About this Guide

This user guide contains information about the Extron IPL T PCS4 and IPL T PCS4i Power Control Interfaces, including explanations of how to install, configure, and operate them. Unless otherwise specified, IPL T PCS4 and PCS4 refer to both product versions throughout this guide.

About the IPL T PCS4 and IPL T PCS4i

The Extron IPL T PCS4 and IPL T PCS4i IP Link Power Control Interfaces are Ethernet-based power management devices that can control power and schedule and monitor up to four output devices via TCP/IP. The IPL T PCS4i is an international version, configured for 220 VAC with IEC connectors.

The PCS4 can be a stand-alone control device or one of many nodes in a distributed control system environment. It lets you remotely power on and off any attached device and to individually sample and store device power levels. The PCS4 has its own web pages, stored in flash memory within the device.

Features

• Remotely powering devices on and off — Centralized management features such as Telnet allow remote powering on and off of projectors, cameras, video conferencing equipment, switchers, and other audio/video equipment.
• Power level monitoring — Four 3-prong power output receptacles sense the power level delivered. Each receptacle can sample and store power levels for a device operating in full or standby mode.
• Individual power threshold settings — User-defined power thresholds can be set for each receptacle. Each threshold can be associated with one or more actions, such as activation of the alarm relay, e-mail notification, and so on. When power exceeds or falls below a stored threshold, the programmed actions are performed.
• Power-up sequencing — Power-up sequencing eliminates power surges at start-up. When the IPL T PCS4 restarts, the receptacles are powered on sequentially, separated by a user-configurable delay. (The factory default delay time is 1 second.) The attached devices are powered up in ascending order from receptacle 1 through 4.

NOTE: The IPL T PCS4 powers up only those devices that were previously powered on when the restart occurred.

- Grouping of receptacles — To support dual powered devices by controlling them simultaneously, two or more receptacles can be grouped together. Grouping and ungrouping can be done via the front panel, TCP ports using Simple Instruction Set (SIS) commands, or the internal web pages.

- Detection device (alarm relay) — This relay on the rear panel can be connected to a relay-controllable siren or other detection device, and can be programmed to react at specified power level thresholds. The alarm relay can be configured for either normally open or normally closed state, which activates the attached alarm device when power drops or increases beyond a specified amount. E-mail messages can be generated based on alarm relay conditions.

- Internet communication — The PCS4 uses standard Ethernet and TCP/IP communication protocols, including ARP (Address Resolution Protocol), DHCP (dynamic host configuration protocol), TCP/IP (Transmission Control Protocol/Internet Protocol), Telnet, and HyperText Transfer Protocol (HTTP).

- Embedded web page serving — The IPL T PCS4 has 900 KB of internal flash memory for storing user-customizable web pages and configuration settings. Nonproprietary programming (HTML and JavaScript™) is available, as well as other programming methods.

• Security — Built-in multilevel security provides user control over access to devices attached to the PCS4. Appropriate security is provided by password protection for Administrator and User levels.

NOTE: The factory configured passwords for all accounts on this device have been set to the device serial number. In the event of an absolute system reset, the passwords convert to the default, which is extron.

- Mounting — The PCS4 can be placed on a tabletop (four rubber feet are provided and can be attached). Optional hardware for mounting the unit under a desktop or podium or on a rack shelf is not included, but can be ordered separately.

③ Power control buttons 1-4 — Press these buttons to switch power on and off to the output receptacle with the corresponding number on the rear panel. These buttons are also used, along with the Set Reference buttons (④), to set the Full and Standby power thresholds.

④ Set Reference (Power threshold) buttons — Press these buttons to set the indicator LEDs for each receptacle to indicate whether the attached devices are operating at Full or Standby power level.

5 LAN status LEDs — These three LEDs show the status of the Ethernet connection as follows:

• 100 — When lit, indicates a 100 Mbps connection speed. Otherwise, the connection speed is 10 Mbps.
• Link — Indicates that the interface has an active network connection.
• Act — (Activity) Blinks while data is being sent or received.

6 Power LEDs (red) — (One for each receptacle) (see figure 7 on page 8) Indicate that power is being supplied to the attached device.
7 Power Management (threshold) LEDs — (Set of two for each receptacle) After the power thresholds have been set, these LEDs indicate the status of the attached device as follows:

- F — Indicates that power is at or above the Full reference threshold.

- S — Indicates that power is at or above the Standby reference threshold, and below the Full threshold.

Setting Up the System Using the Front Panel

The PCS4 can be set up and operated by using:

• The front panel controls
- A computer or other device using an Ethernet connection and IP protocol (Telnet or a web browser)

The following system setup procedures can be performed using the front panel, the embedded web pages, or the SIS commands. Some settings can be adjusted only through a host computer, either using SIS commands via Telnet or using the PCS4 embedded web pages. For details on setup and control via Ethernet, see SIS Programming and Control starting on page 42 or the HTML Configuration and Control starting on page 16.

Setting Up Power Control

To set up control of power to the devices plugged into the PCS4 receptacles, do the following for each device:

1. On the PCS4 front panel, press and release the power control button for the receptacle into which the device is plugged.
   The Power LED at the right of the button lights and remains lit while the receptacle is powered on. It is unlit when the receptacle is powered off.

2. Power on the device, using its own power switch.

Power LED

Setting Power Level Reference Thresholds

You can set the PCS4 to notify you when the power level of a connected device drops from Full to Standby or to None. For each device, you can use front panel controls to set the reference threshold (Full or Standby) at which a notification is triggered.

Until a threshold is set for a receptacle the first time, the status displayed for the receptacle on the web page or given in response to SIS queries is Not Set. Once a threshold has been set, the receptacle status defaults to None if all thresholds are cleared (see None and Not Set thresholds on page 11).

There are two common types of power for electronic devices: soft and hard.

- Soft power devices normally have three power states: On, Standby, and Off. Such devices include projectors, DVD players, and VCRs.

Example: On soft power devices, the Standby mode allows the unit to be powered to its Full power mode via RS-232 commands or a remote. Pressing a PCS4 receptacle button to Off when the receptacle is connected to a device that supports Standby power causes the device to power off.

- Hard power devices normally have two power states: On and Off. These devices include Extron switchers and interfaces.

Example: On Extron switchers, there is no power button or Standby condition, and the unit power can be set only to On and Off from the PCS4 front panel. Therefore, when the power is on, it is at Full power, and can be set for Full reference threshold.

The Full and Standby reference thresholds must be configured with the device attached to the PCS4 receptacle. The thresholds must be set in the correct order, with Full being set first. Follow these steps to set the threshold for each device, using the front panel. (These thresholds also can be configured using the web pages or SIS commands.)

NOTE: The Full threshold must be set first. If Standby is set first, the Standby reference setting is removed by the setting of the Full reference threshold.

1. Connect a device to a power output receptacle on the IPL T PCS4. Make a note of the receptacle number to which you connected it (1 through 4).

2. Press the corresponding front panel button to activate the receptacle. Check to ensure that the Power LED for the receptacle is lit.

Setting the Full power threshold

1. Power on the attached device.
2. Press and hold the Full button on the PCS4 front panel (see the image at right).
3. While holding the Full button, press and release the button for the receptacle into which the device is plugged. Both the F (Full) LED and the S (Standby) LED for the selected receptacle blink twice. Only the Full LED remains lit.

Receptacle Button

1. Release the Full button. The Full threshold for the receptacle is now set.

Setting the Standby power threshold

1. Power off the attached device.
2. Press and hold the Standby button (shown at right).

1. While holding down the Standby button, press and release the receptacle button for the same device for which you set the Full threshold (see the illustration at right). The Standby LED for the selected receptacle blinks twice and remains lit.

1. Release the Standby button.

2. Repeat steps 1 through 9 for any other receptacles to which you have connected devices to be controlled through the PCS4.

NOTE: Settings that are made via the front panel for power output receptacles and reference thresholds take approximately two minutes to be stored in memory. If you recycle power too soon after settings have been made, the settings are lost.

These threshold settings are preserved if the PCS4 AC power is recycled or if power is removed from an attached device. For example:

If the receptacle is set to...	And the power level... The receptacle...
Full drops below the	stored threshold	F (Full) led shuts off, and the S (Standby) LED lights.
Standby	drops below the stored Standby threshold	S LED shuts off.
	exceeds the stored Standby threshold	F LED lights.

To indicate that the configuration has been saved, both the Standby LED and the Full LED light and remain lit when those thresholds are selected.

None and Not Set thresholds

When a Full or Standby reference threshold has been set for a receptacle at some time, and neither threshold is detected, a threshold status of None appears on the web page or can be the response to SIS queries. None also appears if the receptacle is powered off. The None threshold is a state that is detected; it cannot be set manually.

If a receptacle has never been set to a Full or Standby reference threshold, its threshold status is shown as Not Set on the web page and in response to SIS queries. Not Set is the default setting for reference thresholds.

Clearing thresholds

To remove the reference threshold settings from any receptacle:

1. Shut off power to the receptacle that you want to clear by pressing its button on the front panel. The red LED to the right of the button shuts off.
2. Press and hold the Standby or Full button while pressing and releasing the receptacle button. All three receptacle LEDs flash twice, indicating that the settings have been cleared.
3. Release the Standby or Full button that you were holding. If desired, you can now turn power to the receptacle on again by pressing its button.

Grouping Receptacles

Two or more power receptacles can be grouped so that both their connected devices can be controlled simultaneously. To group receptacles using the front panel, follow these steps for each receptacle:

1. Place the receptacle in configuration mode by pressing and holding its receptacle button for 2 seconds. The green Power LED on the front panel flashes continually, indicating that the unit is in configuration mode.
2. Press each receptacle button repeatedly to cycle through the available group selections, indicated by the LEDs beside the button, until you arrive at the setting you want for the receptacle:

3. No LEDs lit — No groups (The receptacle will not be part of any grouping.)
   • S LED lit — Group 1
   • F LED lit — Group 2
   • Red (power) LED lit — Group 3

4. Press either the Standby or the Full button to exit configuration mode.

Ungrouping receptacles

To remove a receptacle from a grouping:

1. Place the receptacle in configuration mode by pressing and holding its button for two seconds, until the green power LED flashes continually.
2. Press the receptacle button repeatedly until none of its LEDs are lit (indicating no groups).
3. Press the Standby or Full button to exit configuration mode.

Front Panel Security Lockout (Executive Mode)

When the PCS4 is in executive mode, it does not accept commands from the front panel. If any button is pressed while the unit is in executive mode, the Power LED flashes three times, indicating that the input from the front panel is not being accepted.

To enter or exit executive mode, press and hold the Standby and Full buttons simultaneously for 2 seconds. The front panel Power LED flashes three times to indicate that the mode has been switched.

NOTE: If power to the PCS4 is recycled while the unit is in executive mode, the PCS4 remains in executive mode.

Resetting the Unit

There are four ways to reset the PCS4 unit (called modes 1, 3, 4, and 5 for the sake of comparison with other Extron IPL products). Reset the unit by pressing the Reset button on the front panel (see Front Panel Features on page 8 for the button location). This button is recessed; it can be accessed with a pointed stylus or small Phillips screwdriver.

ATTENTION:

Figure 8. Reset Button

ATTENTION:

• If the Reset button is continually held in, the LEDs pulse (blink) every 3 seconds, and the PCS4 is put in a different mode, corresponding to the underscored notes in modes 3 through 5. The mode 5 LED blinks three times, the third blink indicating that it is the last mode.
• The reset modes are separate functions, not a progression from mode 1 to mode 5.
• The factory configured passwords for all accounts on this device have been set to the device serial number. In the event of an absolute system reset (mode 5), the passwords convert to the default, which is extron.

Mode 1

Activation	Hold in the Reset button while applying power to the unit.
Result Returns the unit	to the default base firmware that was shipped with the PCS4 from the factory. Event scripting does not start when the unit is powered on in this mode.
Purpose and notes	Use mode 1 to remove a version of firmware if incompatibility issues arise. All user files and settings are maintained. User web pages may not work if you are using an earlier firmware version.

Purpose and notes Mode 5 is useful if you want to start over with control software configuration and to replace events.This reset also removes the initial serial number passwords and sets them toextron.

HTML Configuration and Control

The IPL T PCS4 must be configured before use, or it cannot control other devices. In addition to using the buttons on the PCS4 front panel, you can configure and control the PCS4 via any computer attached to a LAN by using the embedded web pages or SIS commands. This section describes the web pages and provides instructions for using them to configure the IPL T PCS4 series interfaces. Topics include:

• Configuring the Hardware
  • Using the Embedded Web Pages
• Custom Web Pages
  • A/V Device Power Control

Configuring the Hardware

To function together, both the computer and the PCS4 must be configured correctly. The computer must be network-capable with the proper protocols, and the PCS4 must be set up so it can be connected to a LAN (local area network). Note that some settings can be configured only via Internet protocol.

For your computer to communicate with the PCS4, it must be equipped with an network interface card and an HTML browser. To allow your computer to work with Extron Ethernet-controlled products, the TCP/IP protocol must be installed and properly configured.

Setting Up the Computer Using ARP

The Address Resolution Protocol (ARP) command provides a quick way to set up an IP address for the PCS4, using your computer. The ARP commands tell your computer to associate the PCS4 Media Access Control (MAC) address with an IP address that you assign. After entering the ARP command, enter a ping command to access the PCS4 at its new address to confirm the address has been successfully changed.

1. Obtain a valid IP address for your PCS4 from your network administrator.
2. Obtain the PCS4 MAC address (UID#) from the label on its rear panel. The MAC address should have the following format:

∅∅-∅5-A6-XX-XX-XX

where x can be a letter or a number.

1. If the PCS4 has never been configured and is still set for factory defaults, skip to step 4. If not, perform a mode 4 system reset to restore the factory-set values (see Resetting the Unit on page 13 for the resetting procedure).

NOTE: The PCS4 must be configured with the factory default IP address (192.168.254.254) before you execute the ARP command, as described below.

1. On the computer, access the command prompt, then enter arp -s, the desired new IP address for the PCS4, a space, and finally the PCS4 MAC address (taken from the label on the rear panel). For example:

arp -s 10.13.170.15 00-05-A6-00-0A-90

A space must separate arp from the hyphen (-).

Figure 9. ARP-S Command Screen

NOTE: After the arp -s command is issued, the PCS4 changes to the new address and starts responding to ping requests, as described in the next step.

1. To verify that the new address has been set, execute a ping command by entering ping, followed by the new IP address, at the command prompt.

NOTE: Ping is a utility or diagnostic tool that tests network connections. It is used to determine if the host has an operating connection and is able to exchange information with another host.

Example: ping 10.13.170.15

Ping is a utility or diagnostic tool that tests network connections. It is used to determine if the host has an operating connection and is able to exchange information with another host.

The response should be the new IP address of the PCS4, as shown below.

Figure 10. Screen Showing the Ping Command

You can reconnect using either Telnet or a web browser to verify that the update was successful.

1. After verifying that the IP address change was successful, issue the arp -d command at the DOS prompt to remove the address from the ARP table. For example:

arp -d 10.13.170.15

A space must separate arp from the hyphen (-).

Setting Up the Computer Using a Web Browser

To set up the PCS4 using a web browser, you must temporarily configure the computer to communicate with the interface. Then you can change the PCS4 default settings (IP address, subnet mask, and [optionally] administrator name and password) in order to use the unit on an intranet (LAN) or on the Internet (WAN). After you have set up the PCS4 for network communication, you can reset the computer to its original network configuration.

NOTE: The factory configured passwords for all accounts on this device have been set to the device serial number. In the event of an absolute system reset, the passwords convert to the default, which is extron.

IPL T PCS4 LAN port defaults:

• PCS4 IP address: 192.168.254.254
• Gateway IP address: 0.0.0.0
- Subnet mask: 255.255.0.0
DHCP: Off
• Link speed and duplex level: Auto detected

If you use an existing Ethernet LAN intranet, your network administrator can provide you with a unique IP address for the PCS4 or confirm whether you need to set up the PCS4 for Dynamic Host Configuration Protocol (DHCP) to have an address assigned automatically when you sign on.

Setting up the computer for IP communication

Follow these steps to set up communication between your computer and the PCS4.

NOTE: The procedure and illustrations in this section are for Windows XP. For other Windows versions, the screens may appear slightly different.

1. Open the Network Connections page as follows:

a. From the Start menu, select My Network Places.
b. From the Network Tasks left side-bar menu, select View Network connections.

1. Right-click Local Area Connection, then select Properties from the pop-up menu.

Figure 11. Network Connections Dialog Box

1. Select Internet Protocol (TCP/IP), and click the Properties button. If Internet Protocol (TCP/IP) is not on the list, it must be added (installed). See your Windows user manual or the Windows online help system for information on how to install the TCP/IP protocol.

Figure 12. Internet Connection

1. Write down the current IP address of your computer and its subnet mask below. You will need to restore these settings to the computer later.

If an IP address automatically has been selected, make a note of that. If not, write down the following:

IP address:

Subnet mask:

1. Change the IP address of the computer temporarily so that it can communicate with the PCS4.

a. Select the Use the following IP address: radio button.

b. Enter the following values as shown below:

IP address: 192.168.254.253

Subnet mask: 255.255.0.0

Default gateway: Blank or ∅.∅.∅.∅

(The temporary IP address differs from the PCS4 factory default by one digit.)

Figure 13. Enter the IP Address

c. Click OK to save the changes, and exit the network setup.
d. Reboot the computer if required for the changes to become effective.

1. Plug one end of a Category 5, 6, or 6E Ethernet crossover cable into the Ethernet (LAN) connector on the PCS4 rear panel (see Setting Up the LAN Port on page 6 and Rear Panels on page 5 for information on the RJ-45 LAN connector wiring). Plug the other end of the Ethernet cable into the Ethernet port on the computer.

NOTE: If you are using a network hub or switch between the computer and the PCS4, use a straight-through Category 5 cable instead of a crossover cable.

1. Set up the PCS4 IP address (see Configuring the IPL T PCS4 using a web browser for the procedure).

After the PCS4 has been reconfigured, an Ethernet (intranet or Internet) connection can subsequently be used to configure or control it.

NOTE: Both your computer and the PCS4 must be connected to the same LAN. Alternatively, you may use a crossover Ethernet cable to connect the interface directly to your computer Ethernet card.

1. After setting the PCS4 IP address, restore the previous IP configuration of the computer by following steps 1, 2, 3, and 5 but using the original IP address settings that you wrote down in step 4.

Configuring the IPL T PCS4 using a web browser

The default web pages that are preloaded on the PCS4 are compatible with popular web browsers such as Internet Explorer (version 5.5 or higher).

NOTE: The following instructions assume that you have already configured the Windows-based computer, connected it to the PCS4 LAN port, and powered on the interface.

1. Obtain a valid IP address, subnet mask, and gateway address for the PCS4 from your network administrator.

2. Launch a web browser (such as Internet Explorer) on the connected computer (for which you set up the network configuration earlier), and enter the PCS4 default address, http://192.168.254.254, in the address box. The PCS4 default web page is displayed.

3. Select the Configuration tab, then select System Settings from the side bar menu on the left of the screen. A configuration System Settings web page appears. A typical settings screen is shown below.

Figure 14. Example of a Default System Settings Page

1. IP, gateway, and subnet mask addresses follow standard naming and numbering conventions and protocol (nnn.nnn.nnn.nnn). The IP network administrator should provide the addresses to be used with this interface.

Enter the new IP address assigned for the PCS4, the corresponding subnet mask, and gateway address, then click Submit.

The PCS4 takes approximately 2 minutes to store the new settings. After the IP address is changed, your computer loses communication with the PCS4 and a screen appears, indicating that the page cannot be displayed.

1. Close the browser.

2. After changing the PCS4 IP settings, change your computer TCP/IP settings back to their original configuration, and reboot if necessary. You are now able to access the PCS4 web pages to configure the front panel.

Using the Embedded Web Pages

The PCS4 features an embedded web server, which includes factory set web pages. These pages can be replaced with user-designed files, but the default web pages provide many basic features for monitoring, configuring, and controlling the PCS4 via a web browser. This section provides an overview of the embedded web pages. To access the web pages:

1. Launch a web browser (for example, Internet Explorer Ⓤ) on your connected computer.
2. On the browser Address line, enter the PCS4 IP address. If a password has been set, the Enter Network Password dialog box opens.

NOTE: The factory configured passwords for all accounts on this device have been set to the device serial number. In the event of an absolute system reset, the passwords convert to the default, which is extron.

If no password has been set, the PCS4 web page opens, displaying the System Status page. Skip steps 3 and 4.

1. In the User Name field on the password window, enter text of your choice, or leave the User Name field blank.

Figure 15. Password Prompt Window

1. Enter the administrator password in the Password field, and click OK. The PCS4 web page is displayed.

NOTES:

• Passwords must contain 4 to 12 alphanumeric characters. Symbols and spaces are not allowed, and the passwords are case sensitive.
• Administrators have access to all of the web pages and are able to make changes to settings. Users can access only the System Status page.

Viewing the System Status

The System Status web page, accessed by clicking the Status tab, provides information on the current settings. Changes must be made via the Configuration web pages or SIS commands (see SIS Programming and Control on page 42). Personnel who have user access can view this page but cannot access the Configuration or File Management pages to make changes. Figure 17 shows an IPL T PCS4 System Status web page.

Figure 16. System Status Web Page

The System Status page displays information in the following categories:

• System Description: Includes product model, a brief description, part number, and firmware version, plus the current date and time.
• IP Settings: Displays the unit name, IP address, MAC address, and all other current IP settings.
• AC Receptacles: For each receptacle, shows whether the receptacle is turned on or off; the current power level threshold setting (Full, Standby, Not Set, or None); whether the receptacle is part of a group; and the alarm state.
• Current Schedule: Shows the day of the week and the time that any receptacle has been scheduled to power on and off.

Configuration

There are seven Configuration web pages, which only administrators can access. They are listed in the side-bar menu at the left of the Configuration screen. The following sections discuss the tasks that you can perform on these screens.

Specifying system settings

On the System Settings screen, you can set the date and time, and change the IP address information for the PCS4. To change the available system settings:

2. Enter your new information in the IP Settings section or select the date and time from the menus in the Date/Time Settings section.

IP settings

The following settings are available in the IP Settings section:

- Unit Name: The default is the product name followed by the last six digits of the MAC address. You can give the unit a new name (such as LightsOn&Off or BoardroomA-PCS4) consisting of up to 24 alphanumeric characters including the hyphen (-).

NOTE: The first character must be an alpha character, and the last character cannot be a hyphen. The unit name is not case-sensitive.

• DHCP: DHCP is a communications protocol that assigns addresses on the local network automatically. Select the On or Off radio button to enable or disable DHCP.
• IP Address: You can enter a new network address consisting of four sets of up to three digits, separated by periods (nnn.nnn.nnn.nnn).
• Gateway IP Address: A gateway is a device that connects your network with others that may be using different, incompatible communications protocols. You can enter your gateway address (obtained from your network administrator), using the same format that is used for the IP Address. (If there is no gateway, this field defaults to 0.0.0.0.)
• Subnet mask: The subnet mask is used to split IP networks into a series of subgroups (subnets). The mask is a binary pattern that is matched up with the IP address to turn part of the host ID address field into a field for subnets. You can enter a new subnet mask address using the same format that is used for the IP Address.

Date and time settings

The following settings are available in the Date/Time Settings section.

NOTE: This section lets you set the date and time on your PCS4 unit. However, the passage of time is not reflected in the Date and Time fields on the web page. The screen continues to display the settings you entered and does not increment them as time passes. However, the PCS4 itself continues to keep the correct time internally, enabling you to schedule power on and off for the receptacles.

• Date: Select month, day, and year from the pull-down menus.
  • Time: Select hours, minutes, and AM or PM from the pull-down menus.
• Zone: From the pull-down menu, select the time zone for the PCS4 location (number of hours offset from Greenwich mean time).

File Management

The File Management web page allows you to upload and delete files from the server. File names must contain valid alphanumeric characters and underscores; spaces and special characters (symbols) are not allowed. Only personnel with administrator access can view these pages and make changes.

Figure 26. File Management Screen with Two Files Uploaded

Uploading files to the web page

The IPL T PCS4 has approximately 900 KB of space for user files to be uploaded. The Bytes Left field shows how much space remains for uploading files.

To upload files:

1. Select the File Management tab on the IPL T PCS4 web page.
2. On the File Management screen, click Browse to open a Windows file selection window.
3. On the file selection window, locate and select a file to upload. (Only one file at a time can be selected.) The file name and directory path appear in the Browse field on the File Management screen.
4. Click Upload File while the file is uploading, the button label changes to Uploading....

When the uploading is complete, the uploaded file name appears in the Files list with a time stamp showing GMT time, and the button returns to its original state. (Files are listed separately under headings of their extensions.)

Adding a directory

To add a directory or folder to the IPL T PCS4 file system:

1. Enter a name for the directory in the Dir: field, following the slash (/).
2. Click Add Dir.
3. With the directory name displayed, perform the uploading files procedure described in the previous section to add a file to the directory. The directory name appears at the top of the Files column, preceded by a slash (/).

If no files are added to the new directory, it is deleted.

To add more files to the directory, click the directory name to open it, then use the uploading files procedure. To exit the directory, click (root).

Other file management functions

On the File Management screen, you can also do the following:

• Open and view an uploaded file by clicking on its name.
• Delete an uploaded file by clicking the Delete button beside it.
• Delete all uploaded files and directories by clicking the Delete All button.

Custom Web Pages

On the PCS4, custom web pages are supported. You can determine the layout and appearance of the pages displayed on your screen. Server side includes (SSIs) enable you to obtain information from the unit and display the information on web pages. Query strings allow you to send information and commands to the unit to change its configuration or provide you with feedback (see Query Strings on page 35).

Server Side Includes (SSIs)

Server sides includes are a type of HTML comment that directs the web server to dynamically generate data for a web page whenever it is requested. SSIs typically use SIS commands to communicate with the products or attached control devices. Using SSIs, you can design and display custom pages, with PCS4 information provided by the SIS commands.

The basic format for an Extron SSI is:

<!--#echo var=x->

where x is the SIS command to be executed.

When a web page is requested, the web server removes the SSI and replaces it with the answer to the SIS command within quotes.

Figure 27. Example of SSI Command

In the figure 28, the N command is used to request the PCS4 part number.

Query Strings

A query string is the portion of a URL that appears after the question mark. The query string contains parameters or instructions for the web server to execute. The basic format for a query string within a link is:

<a href=index.html?cmd=x>Receptacle 1</a> 

where x is the SIS command to be executed.

When a link is accessed on a web page, the URL is passed to the web server to tell it which web page to return to the browser. The portion of the URL after the question mark is the query string, which contains the SIS command that the IPL T PCS4 will remove and execute.

Like SSI formatted commands, query strings can use any valid SIS command.

The query string in figure 29 turns off DHCP on the IP Link device.

URL Encoding

URL (Universal Resource Locator) encoding is a method of using ASCII hexadecimal characters to display specific characters in a URL. It is used for several reasons. On some operating systems, certain characters are unsafe or not available, and others are reserved by the HTML or URL specification. URL encoding is used to insure compatibility and functionality with most Internet browsers. As a general rule, use the hexadecimal encoding method shown below when these characters appear in your URLs.

The following types of characters do not require encoding in a URL:

Alphanumerics	0-9 a-z A-Z
Special characters	$___.+!*(),
Reserved characters	;/?:@=&When used for their reserved purposes, these characters do not require encoding within a URL.

Figure 32. Characters that Do Not Require Encoding

Reserved characters

Reserved characters should not be encoded when they appear in their conventional meaning in a URL. For example, do not encode the slash (/) when using it as part of the URL syntax. Only encode unsafe characters (defined in the table in the next section) in your URLs.
The following table lists reserved characters.

Characters Hex Dec
$	Dollar 24 36
&	Ampersand 26 38
+	Plus 2B 43
,	Comma 2C 44
/	Forward slash (virgule) 2F 47
:	Colon 3A 58
;	Semi-colon 3B 59
=	Equal 3D 61
?	Question mark 3F 63
@	At symbol 4O 64

Figure 33. Reserved Characters

Unsafe characters

URLs use some characters for special use in defining their syntax and these characters should be encoded. For various reasons, these characters may possibly be misunderstood within a URL. The following table lists unsafe characters.

Characters Hex Dec
	Space 20 32
Quotation marks 22 34
<	Less than symbol 3C 60
>	More than symbol 3E 62
#	Pound 23 35

A/V Device Power Control

Power control of A/V devices may be accomplished once the PCS4 interface has been connected and configured. These include web pages and Telnet.

Custom Web Pages

These pages can either be modified versions of the existing web pages, or new web pages developed in the field.

Web page development can be done with a web site development tool such as FrontPage or Dreamweaver. Custom web pages can be loaded using the embedded File Management web page (see File Management on page 33).

Accessing and Using Telnet (Port 23)

Telnet, short for Telecommunications Network, provides a way for you to connect to a computer or server (in this case, the PCS4 interface) on a network. Once connected via Telnet, you can send ASCII serial commands to configure and monitor the PCS4 settings (see Command and Response Table for SIS Commands on page 45).

1. Click Start, then Run, then enter Telnet, and click OK. The Telnet program starts (see figure 35 on page 39).

Figure 35. Telnet Command Prompt

1. At the command prompt, enter open.
2. At the prompt, enter the IP address of the PCS4 unit. (The default IP address is 192.168.254.254. If the address was changed in the setup or configuration process, use the new address.) Telnet defaults to port 23.

Figure 36. Connecting to the IP Address

1. If passwords were set up for the connected system, you are prompted to log in as an administrator or a user. Otherwise, the system responds with a carriage return and line feed ().

NOTE: The factory configured passwords for all accounts on this device have been set to the device serial number. In the event of an absolute system reset, the passwords convert to the default, which is extron.

1. Once you are connected, you can enter SIS commands as desired.
2. When you are finished entering commands to the interface, press at the command prompt to exit Telnet.

Troubleshooting

Turn on the equipment in the following order:

1. The PCS4 power control interface
2. The power receptacles on the PCS4
3. The connected output devices

If the output A/V device cannot be powered on, check the following:

Power Connections

1. Make sure that the receptacle for each device is receiving power. The red Power LED of the receptacle lights if the receptacle is powered on. If necessary, press the receptacle button to apply power.
2. Ensure that all devices are plugged in properly to the rear panel of the PCS4 and switched on if applicable.

Network Connections

1. Check the network connections and make adjustments as needed. The Link LED is solid green if a network connection is detected. The yellow ACT LED blinks if there is activity on the network. If these LEDs are not lit, either the cable is faulty or not plugged in, or the wrong type of cable is being used (see Connecting the Devices on page 7).
2. At the DOS command prompt, try to ping the unit by entering ping and the IP address assigned to your PCS4 (see Setting Up the Computer Using ARP on page 16). If the PCS4 is connected, you receive the following response to your Ping command:

Figure 37. Successful Ping Command Response

If the connection was not made, the following response appears:

Figure 38. Response to an Unsuccessful Ping Command

If you get a response indicating that the ping was unsuccessful, do the following:

• Make sure your unit is using the appropriate subnet mask (check with your system administrator).

• Make sure your computer does not have a software firewall program which might block the IP address of the unit.

• If contact is established with the unit, but the unit web pages cannot be accessed by your web browser, verify (in the Options or Preferences menu) that your web browser is configured for direct network connection and not set up to use a proxy server.

If you are still experiencing problems, contact the Extron S3 Sales & Technical Support Hotline (see Extron Warranty on page 60).

Downloading Global Configurator Software

The Global Configurator (GC) software is an alternative to using the web pages to configure and monitor the PCS4. GC is a free asset management software that enables flexible, centralized, web-based power management for A/V systems. Using Global Configurator software, administrators can view the immediate status and power levels of all connected devices, schedule powering on and off of the devices, and configure the alarm triggers.

You can download the latest version of Global Configurator from the Extron website (www.extron.com) as follows:

1. Select the Products tab on the Extron website home page.
2. From the sidebar menu at the left of the screen, select Software.
3. On the software products page, click Control Software.
4. On the Control Software page, scroll to locate Global Configurator and click the Download link at right. A login screen appears
5. On the login screen, enter your e-mail address and password.

If you do not have a password, click the click here link and fill in the requested information to obtain a password. When you receive your password, proceed to step 6.

1. On the Download Center screen, fill in the requested information and click Download GVConfigInstallvn.exe. Follow the instructions on the subsequent screens to complete the download.

SIS Programming and Control

This section provides instructions on using the Extron Simple Instruction Set (SIS) commands, which you can use to set up and control the IPL T PCS4 from a host computer or other control system attached to the rear panel LAN port. The following topics are discussed:

• Host-to-Interface Communication
• Using the Command and Response Table
• Command and Response Table for SIS Commands

As shipped, the PCS4 works as a standalone interface, but cannot control any other devices until it is configured. You can set up and control the PCS4 by using the front panel, the web pages, or SIS commands. Both the web pages and the SIS methods are accessed via Ethernet LAN connection. The LAN port defaults are:

IPL T PCS4 IP address:	192.168.254.254
Gateway IP address:	...
Subnet mask:	255.255. .
DHCP: Off

Host-to-Interface Communication

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command sequence. When the PCS4 determines that a command is valid, it executes the command and sends a response to the host device. All responses from the interface to the host end with a carriage return and a line feed (CR/LF = ←), which signals the end of the response character string. (A string is one or more characters.)

Messages Initiated by the IPL T PCS4

When a local event such as a front panel selection or adjustment takes place, the PCS4 responds by sending a message to the host. No response is required from the host. The following PCS4-initiated messages are sent (underlined):

© Copyright 20nn, Extron Electronics, IPL T PCS4 [or -PCS4i], Vn.nn, 60-544-nn

Www, DD Mmm 2011 HH:MM:SS

The PCS4 sends the boot and copyright messages when it first powers on and is connected via Telnet or TCP/IP. Vn.nn is the firmware version number; 60-544-nn is the product part number. The current date and time are displayed. If you are using a Telnet connection, the copyright message, date, and time are followed by a password prompt.

Password Information

NOTE: The factory configured passwords for all accounts on this device have been set to the device serial number. In the event of an absolute system reset, the passwords convert to the default, which is extron.

The ← Password: prompt is displayed only if there is a password defined in the unit. It requires a password (administrator level or user level) followed by a carriage return. The prompt is repeated if the correct password is not entered.

If the correct password is entered, the unit responds with ← Login Administrator ← or ← Login User ←, depending on the password entered. If the passwords are the same for both administrator and user, the unit defaults to administrator privileges.

Error Responses

When the PCS4 receives a valid SIS command, it executes the command and sends a response to the host device. If the PCS4 is unable to execute the command because the command is invalid or it contains invalid parameters, it returns an error response to the host.

The error response codes and their descriptions are as follows:

E12 – Invalid port number
E13 - Invalid value (the number is out of range/too large)
E14 – Not valid for this configuration
E17 - System timed out
E22 – Busy
E24 – Privilege violation
E25 – Device is not present
E26 - Maximum number of connections has been exceeded
E27 – Invalid event number
E28 – Bad filename or file not found

Error Response References

The following superscripted numbers are used within the command descriptions in the Command and Response table to identify commands that may respond as shown:

14	Commands that give an E14 (invalid command for this configuration) response if sent to an IPL product whose power configuration does not support the command
24	Commands that give an E24 (privilege violation) response if you are not logged in at the administrator level
27	Commands that may yield an E27 (invalid event number) response
28	Commands that may give an E28 (file not found) response

Using the Command and Response Table

The PCS4 can be controlled via either a Telnet connection (port 23) or a web browser connection (port 80). The ASCII commands listed in the tables perform the same functions, but they are encoded differently to meet the requirements of each port (Telnet or browser). The ASCII to hexadecimal (HEX) conversion table below is for use with the command and response tables.

Figure 39. ASCII to Hex Conversion Table
The command and response table lists valid ASCII (for Telnet) command codes, the corresponding URL (universal resource locator) encoded (for web browsers) command codes, the interface responses to the host, and a description of the command function or the results of executing the command.
- Upper- and lowercase characters can be used interchangeably in the command field unless otherwise specified.
- Commands may be sent back-to-back without spaces (for example, 2!65V1Z).
- Numbers can be entered as 1, 2, or 3 digits (for example, 8V = 08V = 008V ).
- There are a few differences in how to enter the commands, depending on whether you are using Telnet or a web browser.

- When using these commands through a web browser, you can use the URL reference to shorten the examples. URL refers to the full address of the control interface and web page reference, including all path information (that is, http://192.168.100.10/myform.htm).

- To send any of the commands using a web browser you must prefix them with the full URL followed by ?cmd=.

- For control via a web browser, all non-alphanumeric characters must be represented as the hexadecimal equivalent, %xx, where xx represents the two-character hex byte. For example, a comma (,) would be represented as %2C. Characters such as %, +, and the space character must be encoded as hex bytes, or they will be misinterpreted by the interface.

- Some characters differ depending on the method you use to send the commands:

Telnet Web Browser
Escape (hex 1B) W (must not be hex encoded)
Carriage return (hex ∅D)	Pipe character (|) (must not be hex encoded)

NOTES:

• With Telnet you can use either an Escape command or a W command, and the carriage return or the pipe character. With the web browser, you are required to use a W command and the pipe character.
• In either method, Data = Data that will be directed to a specified port and must be hex encoded if non-alphanumeric.

Common Symbol Definitions

Common Symbol Definitions
←	=	Carriage return with line feed (hex 0D 0A)
← or |	=	Carriage return or pipe symbol (no line feed, hex 0D)
←	=	Carriage return with no line feed (no line feed, hex 0D) (for URL-encoded commands, use the pipe character, | , instead)
Esc	=	Escape key, or hex 1B (use w instead of Esc for web browsers, or at any time)
|	= Pipe (vertical bar) character (URL equivalent to carriage return)
•	= Space
*	=	Asterisk character (which is a command character, not a variable)

Mounting Instructions

This section contains the mounting information for the IPL T PCS4 and IPL T PCS4i.

Mounting the IPL T PCS4 Interface

The IPL T PCS4 can be set on a table, mounted on a rack shelf, or mounted under furniture such as a desk, podium, or tabletop.

Tabletop Use

Four self-adhesive rubber feet are included with the PCS4. For tabletop use, attach one foot at each corner of the bottom side of the unit, and place the PCS4 in the desired location.

UL Rack Mounting Guidelines

The following Underwriters Laboratories (UL) guidelines pertain to the safe installation of the IPL T PCS4 or IPL T PCS4i in a rack.

CAUTION:

• Elevated operating ambient temperature — If the equipment is installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient temperature. Therefore, install the equipment in an environment compatible with the maximum ambient temperature (TMA = +122 °F, +50 °C) specified by Extron.
• Reduced air flow — Install the equipment in a rack so that the amount of air flow required for safe operation of the equipment is not compromised.
• Mechanical loading — When mounting the equipment in the rack, ensure that uneven mechanical loading does not cause a hazardous condition.
• Circuit overloading — When connecting the equipment to the supply circuit, consider the effect that circuit overloading might have on overcurrent protection and supply wiring. Consider equipment nameplate ratings when addressing this concern.
• Reliable earthing (grounding) — Maintain reliable grounding of rack-mounted equipment. Pay particular attention to supply connections other than direct connections to the branch circuit (for example, use of power strips).

Rack mounting procedure

Rack mount the interface, if desired, using the RSU 129 Universal Rack Shelf Kit) as follows:

Figure 40. Mounting the IPL T PCS4 on a Rack Shelf

1. If rubber feet have been installed on the bottom of the unit, remove them.
2. Mount the PCS4 on the rack shelf, using two 4-40 x 3/16 inch screws in opposite (diagonal) corners to secure the unit to the shelf.

3. Attach a blank panel or other units to the rack shelf.

4. Insert the shelf into the rack, aligning the holes in the shelf with those in the rack.

5. Secure the shelf to the rack using the supplied machine screws. This shelf can be mounted in the front or in the rear of the rack.

Under-desk Mounting

The PCS4 can also be mounted under furniture, such as a table or podium surface, using the optional under-desk mounting brackets.

Figure 41. Mounting the IPL T PCS4 under Furniture

1. If rubber feet were previously installed on the bottom of the unit, remove them.
2. Attach the mounting brackets to the unit with the provided machine screws.
3. Insert #8 wood screws into the four pilot holes. Tighten each screw into the mounting surface until slightly less than 14 inch of the screw protrudes.
4. Align the mounting screws with the slots in the brackets, and place the PCS4 against the surface with the screws through the bracket slots.
5. Slide the unit slightly forward or back, then tighten all four screws to secure it in place.

Glossary

This section contains a list of terms that appear in this user guide, with their definitions.

10/100Base-T

Ethernet that uses unshielded twisted pair (for example, UTP - Cat 5) cable, in which the amount of data transmitted between two points in a given amount of time is equal to either 10 Mbps or 100 Mbps.

A

Address Resolution Protocol (ARP)

A protocol for assigning an IP address to a device based on the MAC (Media Access Control), or physical machine address of the device, that maintains a table showing the correlation between the two.

Alarm relay

A single pole, single throw relay, which can be used with a relay-controllable audible siren or any other alarm.

Alarm status

On the PCS4 web page, reflects the state of the monitored condition. It may be inactive, active, or silenced.

AWG (American Wire Gauge)

A standard measurement for wire conductor diameter.

C

Condition

A state for which the PCS4 is being monitored. When a monitored condition is met, the PCS4 may sound an alarm or send an e-mail message, depending on how the system has been configured (via the front panel or the Monitor web page). Examples of conditions that can be monitored include Receptacle Off, Any Change, or Reference: None.

Custom web page

Any file that can be loaded into an IPL T PCS4 and served by the PCS4 internal web server. The web page provides a way to control and monitor the PCS4 output power receptacles. This is true with or without an accompanying event script. Any number and size of graphics can be used, but if they are too large to fit in the PCS4 nonvolatile memory, you can create web pages so that they can be served from another web server. If you install Microsoft Internet Information Services (IIS) on your desktop, you can serve any page on its hard disk. The IPL T PCS4 functions like a little computer with a web server — you can use it for various web-based tasks.

D

DHCP (Dynamic Host Configuration Protocol)

A standardized client-server IP networking protocol that enables network administrators to centrally and automatically manage the assignment of IP addresses in an organization's network.

Driver A package of commands that generates or is the event script that controls devices.

E

Edison power receptacle

Is a standard power connector. The rear panel of the IPL T PCS4, U. S. version, has four female Edison receptacles into which devices are plugged in order to be monitored, scheduled, and powered on and off by the PCS4.

Ethernet A network protocol that uses MAC addresses to exchange data between computers.

Using ARP, with TCP/IP support, Ethernet devices can be connected to the Internet. An Ethernet LAN typically uses unshielded twisted pair (UTP) wires. Ethernet systems provide transmission speeds of 10 Mbps or 100 Mbps. Ethernet is mostly based on the IEEE 802.3 standard.

Executive mode

An operating mode in which the IPL T PCS4 does not accept commands from the front panel. Also called front panel security lockout.

F

Firmware

Embedded software that is stored permanently in read-only memory (ROM) and contains basic instructions for how the PCS4 operates. Firmware upgrades are periodically made available for uploading via the IPL T PCS4 Firmware Upgrade web page.

Full reference threshold

The point at which a device starts to operate at full power.

H

HTTP (HyperText Transfer Protocol)

A web protocol based on TCP/IP that is used to retrieve hypertext objects from remote web pages.

|

IEC power receptacle

Is a standard power connector. The IPL T PCS4i rear panel has four female IEC receptacles into which devices are plugged in order to be monitored, scheduled, and powered on and off by the PCS4i.

IP (Internet Protocol)

The protocol or standard used to send information from one computer to another on the Internet.

IP address

A unique, 32-bit binary number (12 digit decimal number — nnn.nnn.nnn.nnn) based on version 4 of the internet protocol (IPv4) that identifies each sender and each receiver of information connected to a LAN, WAN, or the Internet. IP addresses can be static (see Static IP) or dynamic (see DHCP).

IP net mask/subnet mask

A 32-bit binary number (12 digit decimal number — nnn.nnn.nnn.nnn) used on subnets (smaller, local networks) to help the router determine which network traffic gets routed internally to local computers and which network traffic goes out on the Internet.

M

Media Access Control (MAC) Address

A unique hardware number given to devices that connect to the Internet. When your computer or networking device (router, hub, interface, and so on) is connected to the Internet, a table relates the device IP address to its corresponding physical (MAC) address on the LAN.

P

Ping (Packet Internet Groper)

A command that is used to test connectivity between IP devices. The Internet Control Message Protocol (ICMP) echoes Ethernet packets to determine whether a network device is active and what the bidirectional delay is in communicating with it.

Port number

A preassigned address within a server that provides a direct route from the application to the Transport layer or from the Transport layer to the application of a TCP/IP system.

Power level reference threshold

(See Reference threshold.)

R

Reference threshold

The point at which the power level (full or standby) at which a device is operating changes. This threshold is recognized by the IPL T PCS4, which can be configured to sound an alarm whenever a connected device passes this threshold.

Receptacle

A connector on a power supply that is equipped to receive a plug. The IPL T PCS4 has four receptacles into which devices can be plugged, enabling the PCS4 to monitor and schedule power for the connected devices.

s

SIS (Simple Instruction Set) commands

A set of commands developed by Extron that allows control of the PCS4 via the keyboard of a PC with an Ethernet connection. A minimal number of characters are used in these commands and responses.

Standby reference threshold

The point at which a device starts to operate at standby power.

Static IP

An IP address that has been specifically, instead of dynamically (see DHCP), assigned to a device or system in a network configuration. This type of address requires manual configuration of the actual network device or system and can only be changed manually or by enabling DHCP.

Subnet (See Subnetwork.)

Subnet address

The portion of an IP address that is specifically identified by the subnet mask as the subnetwork.

Subnet mask	A 32-bit address mask used in IP to identify the bits of an IP address that are used for the subnet address. Using a mask, the router does not need to examine all 32 bits, only those selected by the mask.
Subnetwork	A network that is part of a larger IP network and is identified by a subnet address. Networks can be segmented into subnetworks to provide a hierarchical, multilevel routing structure.

T

TCP (Transmission Control Protocol)

A connection-oriented protocol defined at the Transport layer of the OSI reference model. It provides reliable delivery of data.

TCP/IP (Transmission Control Protocol/Internet Protocol)

The communication protocol (language) of the Internet. Computers and devices with direct access to the Internet are provided with a copy of the TCP/IP program to allow them to send and receive information in an understandable form.

Telnet

A standard terminal emulation utility/protocol that allows a computer to communicate with a remote user/client. A user who wishes to access a remote system initiates a Telnet session using the address of the remote client. The user may be prompted to provide a user name and password if the client is set up to require them. Telnet enables users to log in on remote networks and use those resources as if they were locally connected.

NOTE: The factory configured passwords for all accounts on this device have been set to the device serial number. In the event of an absolute system reset, the passwords convert to the default, which is extron.

Threshold (See Reference threshold.)

Threshold status

Reported on the IPL T PCS4 System Status screen in the AC Receptacles section. It indicates the current reference threshold (Full, Standby, None, or Not Set) for each PCS4 receptacle.

U

UID (User ID)

An optional user name, for which a field is provided on the Enter Password window that opens if a password has been assigned to the PCS4.

NOTE: The factory configured passwords for all accounts on this device have been set to the device serial number. In the event of an absolute system reset, the passwords convert to the default, which is extron.

URL (Universal Resource Locator)

The address that lets a resource on the internet be identified, located, and accessed.
