• Installation Overview
• Mounting the IPL T CR48
• Rear Panel Features and Cabling
- Operation

Installation Overview

To install and set up the IPL T CR48, follow these steps:

1. Turn all of the equipment off. Make sure that the input devices (such as motion detectors and alarms), the IPL T CR48, and the output devices (such as projectors or screen lifts) are all turned off and disconnected from the power source.
2. Mount the IPL T CR48 unit (see Mounting the IPL T CR48).
3. Attach the cables (see Connecting the Hardware in the "Connection and Configuration" section.
4. Connect power cords and turn on the devices in the following order: output devices (projector lifts, screen lifts, lighting system, and so on), IPL T CR48, serial controller or computer (PC), then input devices (DSS, cable boxes, and so on).
5. Configure the IPL T CR48 through Telnet, then access the unit using an Internet browser.

Mounting the IPL T CR48

Optional rack shelves and an assortment of mounting kits (furniture and projector mount) are available for use with the IPL T CR48 controller. See the Specifications and Part Numbers section for the part numbers of these accessories. Read the instructions provided with the rack shelf or mounting kit for installation procedures.

The IPL T CR48 includes rubber feet so that it can be set on a table. If you are going to mount the unit to a rack shelf, furniture, or pole, and these feet were attached to the controller, remove the feet before mounting.

UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines pertain to the installation of an IPL T CR48 unit onto a rack.

1. Elevated operating ambient — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature specified by the manufacturer [Tma = +32 to +122 °F (0 to +50 °C)].
2. Reduced air flow — Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
3. Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
4. Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
5. Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (such as the use of power strips).

Rack Mounting

For optional rack mounting, mount the unit on an RSF 123 Rack Shelf (part #60-190-20) (figure 1) or an RSU 129 Universal Rack Shelf (part #60-190-01) (figure 2).

Power

① Power Connection — Plug the external 12 VDC power supply into this connector. The power supply is included with the unit.

WARNING: When wiring, the two power cord wires must be kept separate while the power supply is plugged in. Remove power before continuing.

CAUTION: Always use a power supply supplied by or specified by Extron. Use of an unauthorized power supply voids all regulatory compliance certification and may cause damage to the supply and the end product. Unless otherwise stated, the AC/DC adapters are not suitable for use in air handling spaces or in wall cavities. The installation must always be in accordance with the applicable provisions of National Electrical Code ANSI/NFPA 70, article 75 and the Canadian Electrical Code part 1, section 16. The power supply shall not be permanently fixed to building structure or similar structure.

When connecting the power supply, voltage polarity is extremely important. Applying power with incorrect voltage polarity could damage the power supply and the unit. Identify the power cord negative lead by the ridges on the side of the cord.

Figure 6. Power Connector Wiring

NOTE: Do not tin the stripped power supply leads before installing the captive screw connector. Tinned wires are not as secure in the captive screw connectors and could pull out.

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

Ethernet/LAN

② LAN port — Plug an RJ-45 jack into this socket to connect the unit to a computer network. Use a straight-through cable to connect to a switch, hub, or router, and a crossover cable to connect directly to a PC.

Activity LED — A blinking yellow LED indicates LAN activity. Link LED — A green LED lights to indicate a good LAN connection.

Figure 9. Example Application

Ethernet Connection

This type of connection is used on an ongoing basis to connect the IPL T CR48 to a LAN and to control switching and display devices through the unit.

1. Plug one end of a CAT 5, straight-through Ethernet cable into the rear panel Ethernet connector on the IPL T CR48. See figure 7 for RJ-45 connector wiring.
2. Plug the other end of the Ethernet cable into a network switch, hub, or router connected to an Ethernet LAN or to the Internet.
3. Launch your Web browser on your PC and type the Web address that you set up on the IPL T CR48 (see IPL T CR48 Interface Configuration later in this section) in the Address field of the browser. The IPL T CR48 default Web page is displayed.

Contact Closure Input and Relay Connections

Contact closure input connections

The IPL T CR48 can be connected to any relay providing a closure to ground (closed = logic 1 and open = logic 0). The contact closure inputs are connected to 5 VDC via a 1k ohm pull-up resistor and must be wired with a ground. This allows the input to be tied to devices such as motion detectors and alarms. You can define what this input triggers via control software.

1. Connect one end of the input cable to a 3.5 millimeter, 5-pole captive screw connector, wired appropriately, and plug it into the rear panel input port connector of the unit.
2. Connect the other end of the input cable to the input relay device that will provide a triggering signal.

Relay connections

The IPL T CR48 can be connected to any device that can be activated by a relay closure. This allows the relay to be tied to devices such as lights (preset recall), projector lifts, and screen or drape controllers. You can define what triggers this action via control software.

1. Connect one end of the relay cable to an 8-pole captive screw connector, wired appropriately, and plug it into the rear panel relay port connector of the unit.
2. Connect the other end of the relay cable to the device that will be activated when the triggering signal is received.

Configuring the Hardware

To function together properly, both the controlling PC and the IPL T CR48 must be configured correctly. The PC must be network-capable, with the proper protocols installed and the hardware configured correctly. The IPL T CR48 must be set to recognize and accept commands and pass them through to the projector lift, screen lift, or other controlled device.

PC Configuration

This guide assumes that you have a Microsoft® Windows® PC equipped with an operating network adapter. To allow your PC to work with Extron Ethernet-controlled products, the TCP/IP protocol must be installed and properly configured.

For use on an existing Ethernet LAN intranet, your network administrator can provide you with a unique IP address or confirm whether you need to set up the IPL T CR48 for DHCP (Dynamic Host Configuration Protocol) to have an address assigned automatically when you sign on.

Initial start up

When you power on the IPL T CR48 for the first time, there are two ways to set up the IP address:

• Use the ARP (Address Resolution Protocol) command method.
  • Use the direct PC method.

The default Web pages that are preloaded on the IPL T CR48 provide a way to reconfigure the unit once it has an active network connection with IP access. These Web pages are compatible with Internet Explorer® (version 6.0 or higher). See Communication with the Interface in the "Communication and Control" section for information on accessing and configuring the controller.

Once the unit has been reconfigured, an Ethernet (intranet or Internet) connection can subsequently be used to contact or control it. See Ethernet Connection, earlier in this section, for additional information.

IPL T CR48 Interface Configuration

Configuring the IPL T CR48 using the ARP command

You can make use of the ARP command to set up an IP address for your IPL T CR48. The ARP command tells your computer to associate the MAC address of the IPL T CR48 with the assigned IP address. You must then use the ping command to access the IPL T CR48 unit, at which point the IP address of the device server is reconfigured.

NOTE: To use this setup method, both your computer and IPL T CR48 must be connected to the same LAN. Or, you can use a crossover Ethernet cable to connect the device server directly to the Ethernet card of the computer.

Use ARP to configure the IP address as follows:

1. Obtain a valid IP address for your IPL T CR48 from your network administrator.
2. Obtain the MAC address of the IPL T CR48 from the label on its back panel.
3. If the unit has never been configured and is still set for factory defaults, go to step 4. If not, perform a Mode 4 system reset. See Resetting the Controller in the "Installation and Operation" section for detailed information on reset modes.

CAUTION: The IPL T CR48 unit must be configured with the factory default IP address — 192.168.254.254 — before executing the ARP command, as described in the following steps.

1. On the PC, access the command prompt (from the Windows desktop, click Start, then Run, and type Telnet in the Run dialog box) then execute the arp -s command. Enter the desired new IP address for the IPL T CR48 and the MAC address (located on the rear panel of the controller). For example:

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

Figure 10. Executing the ARP Command

1. Execute a ping command by typing ping followed by a space and the new IP address at the command prompt. For example:

ping 10.13.170.15

After issuing this command, the unit changes to the new address and starts responding to the ping requests, as shown below. You must ping the IPL T CR48 in order for the IP address change to take place.

Figure 11. Unit Response to a Ping Request

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

1. After verifying that the change was successful, enter and issue the arp -d command at the command prompt. For example:

arp -d 10.13.170.15 removes 10.13.170.15 from the arp table

- or -

arp -d* removes all static IP addresses from the arp table.

Configuring the IPL T CR48 using direct PC connection

This type of connection is used initially to connect to and configure the IPL T CR48. The default settings of the unit (IP address, subnet mask, and [optional] administrator name and password) must be changed in order to use the unit on an intranet (LAN) or on the Internet (WAN).

1. Plug one end of a CAT 5 crossover Ethernet cable into the rear panel Ethernet connector on the IPL T CR48. See figure 7 for RJ-45 connector wiring.
2. Plug the other end of the Ethernet cable into the Ethernet port on your PC.

3. Right-click on the Network Neighborhood or My Network Places icon on your Windows (98, 2000, NT, ME, XP) desktop and select Properties from the menu.

4. Select Internet Protocol (TCP/IP) from the list and click on Properties.

- Or -

If you are using Windows 2000:

a. Right-click Local Area Connection and select Properties from the menu.
b. Select Internet Protocol (TCP/IP) from the list.
c. Click on Properties.

If Internet Protocol (TCP/IP) is not on the list, it must be added (installed). Refer to your Windows user guide or the online Help system for information on how to install the TCP/IP protocol.

1. Write down your current IP address and subnet mask below. If your PC is set to "Obtain an IP address automatically," make a note of that, instead.

IP Address:

Subnet Mask:

1. Click Specify an IP address or Use the following IP address (depending on your operating system) and leave the default gateway blank. Enter the following values: IP Address: 192.168.254.253

Subnet Mask: 255.255.0.0

1. Save the changes and exit the Network setup. Reboot the PC, if required, for the changes to become effective.

2. Launch your Web browser (Internet Explorer), and type http://192.168.254.254/index.html in the Address field of the browser. The IPL T CR48 default Web page is displayed. See IPL T CR48 Interface Configuration, earlier in this section, for more information on configuring your unit.

3. After configuring your IPL T CR48, repeat steps 3 and 4 to change your TCP/IP settings back to their original configuration.

Ports Overview

Contact Closure Input Ports

The contact closure inputs on the IPL T CR48 are able to detect a closed circuit between any of the inputs and ground. The contact closure input ports use a 1k ohm pull-up resistor in a TTL (5 VDC) circuit to sense external switch or contact closure.

By connecting one side of an external switch or relay to the contact closure ground port and the other side to one of the four contact closure input ports, logic 1 (closed) can be produced. Logic 0 (open) can be produced by disconnecting either side of the external switch or relay from the IPL T CR48.

Figure 12. Equivalent Circuit for Contact Closure Input

Relay Ports

The relay ports can be used for remote switching of low level signals. The relays can be activated via software in three ways:

1. The Port Settings default Web page found under the Configuration tab (figure 16)
2. Telnet
3. An event script running on the IPL T CR48

The Port Settings Web page allows you to turn any of the eight relays on or off.

Telnet allows you to send SIS™ commands (see Programmer's Guide for the Telnet and Web Browser, later in this section, to turn the relays on or off directly.

Event scripting allows an event script to turn the relays on or off based on the state of the four inputs on the IPL T CR48, or any other event script conditions.

States of the relay ports are volatile; if a given relay port is on and power for the unit is turned off, the state of the port is not remembered. When the unit is powered on, the relay ports are open and the corresponding LED will be off.

Communication with the Interface

Web Server

The on-board Web server is displayed as a set of default Web pages, which can be accessed via a Web browser. These pages are the primary means of communication with, and control through, the IPL T CR48 controller. Web browsers such as Microsoft® Internet Explorer® (version 5.5 or higher) can be used, but if using Internet Explorer, you must also have Microsoft Script (version 5.6 or higher).

The PC used to access the Web server and the unit should be connected to your local intranet or the Internet.

If you have established passwords for the unit, you will be shown a Password window when your browser accesses the IPL T CR48 (but not when you initially access the Web server since no passwords have been established). Your level of control over the unit depends on the password you enter in this Password window. If you enter the administrator password, you have control of all matters of configuration. If you enter a user password, you are restricted to control of only A/V devices and viewing status.

Accessing and using the Web server

To log on and view system status:

1. Double-click the Web browser icon on your Windows ^® desktop to launch your Web browser.

2. Enter the IP address of the unit (see IPL T CR48 Interface Configuration in the "Connection and Configuration" section) in the Address field at the top of the screen and press the Enter key on your keyboard. The Enter Network Password dialog box (figure 13) is displayed if a password has been set (this will not happen the first time you access the unit, as no password is set at the factory).

Figure 13. Enter Network Password Dialog Box

The System Status page (figure 14) is displayed, showing the current IP and port settings of the unit.

Figure 14. System Status Screen

Establishing or changing system or port settings

The System Settings screen is used to initially configure or change the configuration of the IPL T CR48. You may be required to change system settings if your network changes or if port settings change as you add or change display devices or switchers.

To configure system or port settings:

1. Select the Configuration tab and the System Settings screen (figure 15) is displayed.

Figure 15. System Settings Screen

1. Make changes to the IP settings or the date and time settings, as necessary.
2. Click Submit to enter the changes or click Cancel to revert to the previous settings.
3. Click Port Settings on the menu (on the left side of the window) and the Port Settings screen (figure 16) is displayed.

Figure 16. Port Settings Screen

1. Select the desired port and make changes to the port settings, as necessary.
2. Click Submit to enter the changes or click Cancel to revert to the previous settings.

Setting and changing your passwords

For security reasons, you may want to set passwords initially or change passwords either periodically or on a schedules basis. If passwords have been set, you must log on as an administrator to change the passwords.

To set or change the passwords:

1. Click the Passwords link on the menu (on the left side of the window). The Passwords screen (figure 17) is displayed.
2. Enter the passwords for the administrator, user, or both, then re-enter the same passwords to confirm.
3. Click Submit to enter the changes of click Cancel to revert to previous settings. If the fields are blank, no passwords have been assigned.

Figure 17. Passwords Screen

1. Once passwords have been set, you will be required to enter a password (figure 13) whenever you log on to the unit.

NOTES: To clear a password, enter a single space, repeat the entry, and click Submit.

If there is no administrator password, your user password will not be saved.

Editing and adding e-mail alerts

If you have created scheduled events or monitoring tasks on the IPL T CR48, you can write an e-mail alert with a message corresponding to that event or task (for example, a timer notification indicating it is time to replace a projector light bulb). The e-mail alert can notify up to eight recipients at one time.

To edit notification e-mail addresses from the Email Alerts page:

1. Click Email Alerts on the menu (on the left side of the window). The Email Alerts screen (figure 18) is displayed.

Figure 18. Email Alerts screen

1. Click Edit to go into edit mode.
2. Add, update, or change the IP address and domain name of your mail server under Email Settings.
3. Click Save to keep the changes.
4. Click the Edit buttons to independently edit each e-mail address and file name.

a. Enter the e-mail address of the alert recipient in one of the numeric mailboxes under Email Address.
b. Enter the name of the file containing the alert message under File Name.
c. Click Save to keep changes to recipient e-mail addresses and file names.

NOTES: File names must end with an *.eml extension.

Due to the 7-character limit for full file names, it is advised that you use numeric titles (such as 1.eml or 24.eml). Numeric titles reduce the characters of the file name and assist in keeping the alert files organized. However, alphabetical titles are permitted.

To finalize your new e-mail alerts within the Web server, do the following:

1. Obtain your gateway IP address from your system administrator.
2. Click System Settings on the menu on the left side of the window.
3. Within the System Settings screen (figure 15), enter the gateway IP address into the Gateway IP Address field.

IPL T CR48 • Communication and Control 20

Sending an e-mail alert through Telnet

To complete the process of sending an e-mail alert, you must send it through a Telnet session and receive confirmation. To do so:

1. Open a Telnet session. See Accessing and using Telnet, later in this section, for instructions on how to do this.
2. Use the "Send e-mail" SIS command to send the alert to the e-mail address of a numeric mailbox (figure 18). See Programmer's Guide for the Telnet and Web Browser, earlier in this section, for specific command code.

For example, the code for sending an alert from the 4th numeric mailbox would be:

Esc 4 SM←

Refer to the Global Configurator Help file for detailed information on monitoring and scheduling.

Upgrading the firmware

Firmware upgrades become available as improvements are made to the versatility and functionality of the IPL T CR48. These upgrades are available for download from the Extron Web site (www.extron.com).

CAUTION: The firmware file you select to upload must have an *.S19 extension. Uploading the incorrect file may cause your unit to stop working.

To upgrade the firmware:

1. Click Firmware Upgrade on the menu (on the left side of the window). The Firmware Upgrade screen (figure 19) is displayed.

Figure 19. Firmware Upgrade Screen

1. Click Browse to find the most current available version of the firmware that has been downloaded on your PC.
2. If you find a later version than the one shown above the box, click Upload to upgrade to the newer version.

CAUTION: If you leave the page before upload is complete, the upload will be cancelled.

Managing files

File Management is a useful tool that allows you to use and upload existing and custom Web pages. Custom pages can be developed using a third-party Web page development program such as FrontPage® or Dreamweaver®. File Management also allows you to remove unnecessary or outdated files when they are no longer needed.

To add or update files:

1. Select the File Management tab. The File Management screen (figure 20) is displayed.

Figure 20. File Management Screen

1. Click Browse to locate the file you want to upload.
2. Click Upload File to upload the file.

The file is added to the list of files under the Files column. After ten files have been loaded, additional file management pages appear in the page navigation area (on the right side of the screen).

To delete unwanted files:

1. Select the File Management tab and the File Management screen (figure 20) is displayed.
2. Find the file you want to delete in the Files list.
3. Click Delete for the file to be deleted. If you want to delete additional files, wait for the screen to refresh before clicking Delete for the next file.

If you want to delete all files, click Delete All. The file count reverts to zero and all subsequent pages are deleted.

Programmer's Guide for the Telnet and Web Browser

Using the Command/Response Table

The following are either Telnet (port 23) or Web browser (port 80) commands. There are some minor differences when implementing these commands via Telnet or via URL encoding using a Web browser. All commands listed below will work using either connection method, but due to some limitations of the Web browser, the encapsulation characters are modified to make sure that the Web browser will properly handle them. All examples in the command/response table show the proper implementation in a Telnet or Web browser session.

NOTE: For Web browsers, all non-alphanumeric characters must be represented as their hex equivalent such as %xx where xx equals the two character representation of the hex byte that needs to be sent (for example, a comma would be represented as %2C).

Telnet Web Browser ____

Escape (Hex 1B) W [must not be encoded]

Carriage Return (Hex 0D) Pipe Character ( | ) [must not be encoded]

When using these commands through a Web browser, the URL reference is used below to shorten the examples. This would, in practice, be the full URL of the control interface and Web page reference including all path information (for example, http://192.168.100.10/myform.htm).

To send any of the commands using a Web browser, you need to prefix them with the full URL followed by ?cmd= (see URL Encoding, later in this section).

NOTE: With Telnet you can use either the "Escape" character or the "W" character, and the carriage return or the pipe character. With the Web browser, you are required to use the "W" character and the pipe character.

In either method {Data} signifies that data will be directed to a specified port and must be encoded if it is non-alphanumeric.

The table on pages 28 through 32 lists the commands that the IPL T CR48 recognizes as valid, the responses that are returned to the host, a description of the function of each command, and the results of executing the command.

NOTE: Upper and lower case text can be used interchangeably except where noted.

Symbol definitions are shown below. An ASCII to HEX conversion table is also provided in figure 21.

Copyright information

(c) COPYRIGHT 2009, EXTRON ELECTRONICS IPL T CR48, Vx.xx, 60-544-x5

Tue, 10 Aug 2010 16:29:10

The copyright message is displayed upon connecting to the IP Link® product via TCP/IP or Telnet. Vx, xx is the firmware version number. The part number of the unit, the current date, and time are displayed as well. This is followed by a password prompt.

Password information

The “◀Password:” prompt 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 passwords are the same for both administrator and user, the unit defaults to administrator privileges.

Error responses

When the IPL T CR48 receives a valid command, it executes the command and sends a response to the host device. If the unit is unable to execute the command because the command contains invalid parameters, it returns an error response to the host.

E10 — Invalid command

E12 — Invalid port number

E13 — Invalid parameter

E14 — Not valid for this configuration

E17 — System timed out

E22 — Busy

E24 — Privilege violation

E25 — Device not present

E26 — Maximum number of connections exceeded

E27 — Invalid event number

E28 — Bad filename/file not found

E31 — Attempt to break port pass-through when not set (A user or software attempted to disable the port redirect feature when it wasn't already set or active.)

References to errors (at command descriptions on the following pages)

²⁴ = Commands that give E24 (privilege violation) if not administrator level

²⁷ = Commands that may give E27 (invalid event number)

²⁸ = Commands that may give E28 (file not found)

URL Encoding

URL encoding is the method of using ASCII hexadecimal characters to display specific characters in a URL. URL encoding 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 ensure compatibility and functionality with most Internet browsers. As a general rule, use the URL hexadecimal encoding method shown in the following tables 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.

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 below) 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	40	64

Unsafe characters

URLs use some characters for “special use” in defining their syntax and should be encoded. For various reasons, these characters present the possibility of being misunderstood within a URL and are therefore considered “unsafe.”

The following table lists unsafe characters.

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

NOTE: This command resets all settings/memories. The ZQQQ command resets everything (all settings, adjustments, the IP address, and subnet mask) to the factory default values. Files in flash memory are also erased by this command. The firmware version does not change. The IP address is reset to 192.168.254.254 and the subnet mask is reset to 255.255.0.0.

Device Control

Control of A/V devices can be accomplished in several ways once the IPL T CR48 has been connected and configured. These include Web pages, Telnet, and direct port access.

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 with the Web server File Manager (see Managing files earlier in this section).

Telnet (Port 23)

Telnet, short for Telecommunications Network, provides a way for you to connect to a computer or server (in this case the IPL T CR48) on a network. Once connected via Telnet, you can send ASCII serial commands (see Programmer's Guide for the Telnet and Web Browser earlier in this section) to control devices connected to the IPL T CR48.

Accessing and using Telnet

1. From the Windows desktop, click Start, then Run.
2. In the Run dialog box, type Telnet.
3. Click OK. The Telnet program starts (figure 22).

Figure 22. Telnet Command Prompt

1. At the command prompt, type open and press Enter on the keyboard.
2. At the prompt, type the IP address of the IPL T CR48. (The default IP address is 192.168.254.254, but it may have been changed in the setup or configuration process. If it was changed, use the new address.) Telnet defaults to port 23.

Figure 23. Connecting to the IP Address

1. If passwords were set up for the connected system, you will be prompted to log in as Administrator or User. Otherwise, the system responds with a .
2. Once you are connected, you can enter serial (ASCII) commands as desired.
3. When you are through entering commands to the IPL T CR48, type quit at the command prompt to quit Telnet.

Troubleshooting

For best results, make connections in the following order. Turn on:

1. Control devices (such as a PC or laptop)
2. IPL T CR48
3. Output devices (such as projector lifts, screen lifts, and lighting systems)

If the output A/V device cannot be remotely controlled, check the following:

Power Connections

1. Ensure that all devices are plugged in.
2. Ensure that each device is receiving power. The power LED on the front panel of the IPL T CR48 lights if the device is receiving power.

Data Connections

1. Check the cabling connections and make adjustments as needed. The LINK LEDs on the IPL T CR48 and the computer should be solid green if a network connection is detected. 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 Hardware in the "Connection and Configuration" section).
2. Try to ping the unit by typing ping 192.168.254.254 at the Windows command prompt, or use the Web address provided to you by your system administrator. If you get no response:

a. Ensure that your unit is using the appropriate subnet mask (check with your system administrator).
b. Ensure that your PC does not have a software firewall program that might block the IP address of the unit.

1. 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 of the browser) 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, call the Extron S3 Sales & Technical Support Hotline.

Configuration

If, when configuring a unit, the MAC address on the rear panel is not visibly accessible and the IP address is not known, use the direct PC connection method (see the Connection and Configuration section).

NOTE: If the unit is not new (for example, out of the box), please see Resetting the Controller in the "Installation and Operation" section for instructions on how to reset the IP back to factory default.

Glossary

This section provides definitions of terms related to the IPL T CR48.

10/100Base-T — Ethernet that uses Unshielded Twisted Pair (such as UTP - CAT 5) cable, where the amount of data transmitted between two points in a given amount of time is equal to either 10 Mbps or 100 Mbps.

Address Resolution Protocol (ARP) — ARP is a protocol which assigns an IP address to a device based on the MAC or physical machine address of the device.

Contact Closure — An encapsulated switch containing two metal wires that serve as the contact points. When these contact points meet, it creates a complete circuit (for example, ports 1 through 4 to ground on the IPL T CR48).

Custom Web page — Any file that can be loaded into an IPL T CR48 and served by the unit's internal Web server. A custom Web page can provide control of devices attached to the IPL T CR48 without use of the GlobalViewer® (GV) or Global Configurator (GC). 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 on the IPL T CR48, you can write your Web page 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 CR48 functions like a small computer with a Web server — you can use it for various Web tasks.

DHCP — Dynamic Host Configuration Protocol (DHCP), which is a standardized communications protocol that enables network administrators to locally and automatically manage the assignment of IP addresses in a network for an organization.

Driver — A GC compatible package. It includes the event script that controls devices.

Ethernet — A network protocol that uses MAC addresses instead of IP addresses to exchange data between computers. Using ARP (see above), with TCP/IP support, Ethernet devices can be connected to the Internet. An Ethernet LAN typically uses unshielded twisted pair (UTP) wires. Ethernet systems currently provide transmission speeds of 10 Mbps or 100 Mbps.

Event script — A program that runs on an IPL T CR48 controller, and issues queries and commands to the attached devices. Event scripts are written in the “Extron C” language (*.sc), and compiled into an event script (*.evt). GC performs this compilation. The compiled result is loaded onto the IPL T CR48. The Extron C language is similar to ANSI C, with some differences. As long as event scripts are turned on, event scripts run continuously on the unit.

Global Configurator (GC) — A Windows® program that, based on user input, creates a GlobalViewer (GV). GC requests system information such as which devices you have and your current list of IP addresses. With this information, GC creates a GlobalViewer for your specific devices. GC also compiles the event scripts and loads the GV and event scripts onto the box. When using GC, you must specify the port number for each device (for attached devices to be controlled, they must be on that port). In order for multiple IP Link® units to appear in the same GV, all the units must be configured at the same time, using GC.

GlobalViewer (GV) — A set of Web pages (HTML, XML, JS) and graphics that are loaded into the memory of an IPL T CR48. These pages provide an interface for control of devices attached to the IPL T CR48. They communicate with the event scripts running on the unit, and the event scripts issue the commands and queries. This communication between the Web pages and the event scripts occurs through predetermined memory locations in the IPL T CR48. GV is initially created by GC; however, it is possible to edit the GV HTML, XML, and JavaScript files outside of Global Configurator. This edited GV is called "hard-coded" or manually generated GV.

HTTP — HyperText Transfer Protocol (HTTP), which is a Web protocol based on TCP/IP, that is used to fetch HyperText objects from remote Web pages.

Internet Protocol (IP) — 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, xxx.xxx.xxx.xxx) 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 Netmask — A 32-bit binary number (12-digit decimal number, xxx.xxx.xxx.xxx) 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.

Media Access Control (MAC) Address — A unique hardware number given to devices that connect to the Internet. When your computer or networking device (such as a router, hub, or interface) is connected to the Internet, a table (see "ARP") relates the IP address of the device to its corresponding physical (MAC) address on the LAN.

Pass-through — Allows control systems to work with the IPL T CR48 and provides a link between two ports.

Ping — A utility 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.

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.

Relay — An electromechanical device that opens or closes electrical contacts when energized by an isolated electrical coil circuit.

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.

Transmission Control Protocol/Internet Protocol (TCP/IP) — 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 utility available on most PCs that allows the computer system to communicate with one of its remote users or clients. 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.

URL encoding — Allows you to send information and commands to the unit to change its configuration or provide you with feedback.
