About this Manual

This manual describes the function, installation, configuration, and operation of the IPL T SFI244 Ethernet control interface.

About the IPL T SFI244 Interface

The IPL T SFI244 interface is an Ethernet-based control interface designed to be used as one of many nodes in a distributed control system environment, or as a stand-alone control interface allowing legacy products to link to today's IP Link®-based networks.

The IPL T SFI244 has one 10-pole, 3.5 millimeter captive-screw connector for the two bidirectional COM ports and the four digital I/O ports. It also has one 8-pole, 3.5 millimeter captive-screw connector for the four IR output ports. The ports are fully software configurable via the 10/100 Ethernet port using a Web-based interface. The IPL T SFI244 only supports the RS-232 protocol (RS-422 and RS-485 protocols are not supported). The IR ports are capable of transmitting both carrier and non-carrier (wired or IR) control data.

The IPL T SFI244 interface can host its own Web pages, stored in flash memory within the devices. It supports Telnet, SMTP (simple mail transfer protocol), ICMP (Internet control message protocol) or ping, and DHCP (dynamic host configuration protocol).

The IPL T SFI244 ships with an external, desktop, 12 VDC, 1A power supply (Extron part #28-071-01), that accepts 100-240 VAC input.

Features

Distributed system architecture — A decentralized architecture ensures fault-tolerance throughout the system and stand-alone reliability.

UL Guidelines for Rack Mounting

The following Underwriters Laboratories (UL) guidelines pertain to the installation of an IPL T SFI244 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 ^ (0 to +50 ^)] .

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 1U Rack Shelf (part #60-190-20) (see figure 1) or an RSU 129 standard Universal 1U Rack Shelf (part #60-190-01) (see figure 2). On the standard rack shelf, the unit mounts in one of four locations to the rear of the rack or in one of four locations to the front of the rack.

1. If feet were previously installed on the bottom of the IPL T SFI244 unit, remove them.
2. Mount the unit 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. Install blank panel(s) or other unit(s) 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.

Configuring the Hardware

To function together properly, both the controlling PC and the IPL T SFI244 must be configured correctly. The PC must be network-capable, with the proper protocols installed and the hardware configured correctly. The unit must be set to recognize and accept commands, as well as pass them through to the switcher, projector, or other controlled device.

PC Configuration

This manual assumes that you have a 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 SFI244 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 SFI244 for the first time, there are two ways to set up the IP address.

1. Use the ARP (Adress Resolution Protocol) command method.
2. Use the direct PC method.

The default Web pages that are pre-loaded on the IPL T SFI244 interface provide a way to reconfigure the IPL T SFI244 once it has an active network connection with IP access. These Web pages are compatible with Internet Explorer ^® (version 5.5 or higher). See Communication with the Interface for information on accessing and configuring the interface.

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

IPL T SFI244 Interface Configuration

Configuring the IPL T SFI244 using the ARP command

You can make use of the ARP command to set up an IP address for your IPL T SFI244. The ARP command tells your computer to associate the IPL T SFI244 unit's MAC address with the assigned IP address. You must then use the ping command to access the IPL T SFI244 unit, at which point the device server's IP address will be reconfigured.

NOTE: To use this setup method, both your computer and IPL T SFI244 interface must be connected to the same LAN. Or, you can use a crossover Ethernet cable to connect the device server directly to your computer's Ethernet card.

Use ARP to configure the IP address as follows:

1. Obtain a valid IP address for your IPL T SFI244 from your network administrator.
2. Obtain the IPL T SFI244 unit's MAC address from the label on its rear 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 Unit for detailed information on reset modes.

CAUTION: The IPL T SFI244 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. Access the command prompt, then execute the arp -s command.

Enter the desired new IP address and the MAC address (the MAC address is located on the rear panel's upper right corner) for the IPL T SFI244 unit. For example:

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

C:\>arp -s 10.13.178.15 00-05-A6-00-00-90 C:\>

Figure 13. Executing the ARP Command

1. Execute a ping command by typing your new IP address in 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. The IPL T SFI244 unit's IP address should now be updated to the new address, and then you can reconnect using either Telnet or the Web to verify that the update was successful.

C:\>arp -> 10.13.170.15 00-05-06-00-00-90 C:\>ping 10.13.170.15 Pinging 10.13.170.15 with 32 bytes of data: Reply from 10.13.170.15: bytes=32 time<10ns TIL=64 Reply from 10.13.170.15: bytes=32 time<10ns TIL=64 Reply from 10.13.170.15: bytes=32 time<10ns TIL=64 Reply from 10.13.170.15: bytes=32 time<10ns TIL=64 Ping statistics for 10.13.170.15: Packets: Sent = 4, Received = 4, Lost = 0 (0; loss), Approximate round trip times in nilli-seconds: Minimun = 0ns, Maxinun = 0ns, Average = 0ns C:\>

Figure 14. Unit Response to a Ping Request

1. After verifying that the change was successful, issue the arp -d command in 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 SFI244 using direct PC connection

This type of connection is used initially to connect to and configure the IPL T SFI244. The unit's default settings (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 SFI244. See figure 6 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. (If you are using Windows 2000, right-click Local Area Connection and select Properties from the menu, then select Internet Protocol (TCP/IP) from the list and click on Properties again.) If Internet Protocol (TCP/IP) is not on the list, it must be added (installed). Refer to your Windows user manual or the online Help system for information on how to install the TCP/IP protocol.
5. 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 on 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. The IPL T SFI244 default Web page is displayed. See IPL T SFI244 Interface Configuration for more information on configuring your unit.
3. After configuring the IPL T SFI244 interface, repeat steps 3 and 4 to change your TCP/IP settings back to their original configuration.

Firmware upgrades

Firmware upgrades become available as improvements are made to the versatility and functionality of the IPL T SFI244. These upgrades are available for download from the Extron Web site. See Upgrading the firmware for more information on upgrading the firmware.

Communication and Control

This section describes communication with the IPL T SFI244 interface as well as A/V device control. Topics that are covered, include:

• Ports Overview
• Communication with the Interface
• Programmer's Guide for the Telnet and Web Browser

Ports Overview

Flex I/O Ports

Extron flex I/O ports are configurable input or output ports designed to provide connectivity to various devices such as motion detectors, alarms, lights, LEDs, buttons, photo (light) sensors, temperature sensors, or relays. All flex I/O ports are tied to a common ground, but can be individually configured to operate in one of three different modes:

- Digital Input

- Digital Output

- Analog Input

These ports can be configured by using the default Web pages of the IPL T SFI244 Web Server (see figure 15; also see Establishing or changing system or port settings) or by dynamically using the Simple Instruction Set™ commands (see Programmer's Guide for the Telnet and Web Browser) via Telnet, scripts, or Web pages.

Figure 15. Default Web Page for Flex I/O

Digital input

When a flex I/O port is configured as a digital input, the port measures two states: 1 or 0; On or Off; high or low. A closed circuit = a logic 1 and an open circuit = a logic 0.

+30V+5V 2K SW2 24KS W1 I/O GND

Figure 16. Equivalent Digital Input Circuit

The Digital Input mode has two configurable options:

1. The ability to turn on an internal pull-up resistor to +5 VDC (shown below as SW2)

2. Adjustable detection threshold voltages

The default threshold voltages follow standard TTL logic: a voltage below 0.8 VDC is measured as logic low and a voltage above 2.0 VDC is measured as logic high. Using an adjustable threshold, the integrator can select the proper high and low voltages for the installation.

NOTE: In the figure below, the SW2 switch is turned closed, activating the +5 VDC and 2K pull-up resistor.

+30V+5V 2K SW2 24K I/O GND

Figure 17. Sample Wiring for a Digital Input Reading an External Pushbutton Switch

If the integrator selects threshold voltages that are more than 0.1 V apart, a deadband, or hysteresis, will be established.

In the following example, the lower threshold voltage is set at +6 VDC and the upper threshold is set at +16 VDC. The shaded bands show state changes on the logical outputs.

The range between 6-16 VDC is the deadband in which the signal can fluctuate without affecting the input state.

Figure 18. High and Low Transitions of Adjustable Threshold with Deadband (Hysteresis)

Digital output

When a flex I/O port is configured as a digital output, it offers two output states: "on" and "off". When the port is set to an "on" state, (SW1 is closed), the I/O pin is connected to ground (each I/O port is capable of sinking 250 mA max). When the port is set to the "off" state, (SW1 is open), the output pin is floating.

If the application calls for TTL compatibility, SW2 can be selected to provide a 2K pull-up resistor to +5 VDC.

+30V 24KΩ W1 I/O GND +5V 390

Figure 19. Sample of a Digital Output Port Driving an LED Using an External +5 VDC Source

Analog input

When a flex I/O port is configured as an analog input, the port can measure 0 to 25.3 VDC with 12-bit accuracy. A DC level is indicated by a count from 0-4096 (≈ 6 mv/count).

+30V 24K I/O 10 10K +12V GND

Bidirectional Serial Control Interface Ports

The IP Link ^® family of products has several models that incorporate bidirectional serial control ports. The serial ports allow for control of a wide variety of existing Extron and third-party devices. The most common serial control formats are RS-232, RS-422, and RS-485. With the IPL T SFI244, the captive screw connector is an implementation for the serial control ports.

Captive Screw Connectors — On the IPL T SFI244 unit, all of the serial interface ports are connected on captive screw terminals. When using the ports on the captive screw terminals, only RS-232 control is available, and hardware handshaking is unavailable. Since RS-232 is the most common control interface encountered, this port configuration allows for quick termination.

NOTE: Pacing and handshaking are not supported on captive screw connectors.

All of the bidirectional serial ports are completely software configurable. Baud rates can be set up to 115 Kbs. Using the Simple Instruction Set (SIS) commands found in the Programmer's Guide for the Telnet and Web Browser, these ports can be configured to control most serial devices. Once a port is configured and properly cabled to the controlled device, serial commands can be issued to the port from a Web page, Telnet connection, or by using the advanced scripting capability built into the IP Link product family.

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 SFI244 interface. Web browsers such as 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 must have a connection in common with the IPL T SFI244. In other words, both the unit and the PC should be connected to your local intranet or the Internet.

If you have established passwords for the interface, you will be shown a password window when your browser accesses the IPL T SFI244 (but not when you initially access the Web server, since no passwords have been established). Your level of control over the interface depends on the password you enter in this password screen. If you enter an administrator password, you have control of all matters of configuration. If you enter a user password, you are restricted to control of 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 SFI244 Interface Configuration) in the Address field at the top of the screen and press the Enter key. The Password window (see figure 21) is displayed if a password has been set (this will not happen the first time you access the interface, as no password is set at the factory).

IR Learning

The IPL T SFI244 IR can "learn" commands from a third-party remote control device in order to control devices such as VCRs, audio tape players, or DVD players. IR learning can be performed in conjunction with GlobalViewer to assist in controlling commonly used functions.

During IR learning, you must hold the device remote between two inches and twelve inches away from the IR pick up device (see figure 31).

2-12" 15 deg. (typ)

Figure 31. IR remote distance

Creating a driver with the IR Learner software

To use your third-party remote device with the IPL T SFI244, the functions of your third-party driver must be "learned" by the IPL T SFI244. In other words, you must create a driver for your remote control device. You can create a new, custom driver or manipulate an existing driver. Both can be accessed or created through the IR Learner software.

To create a driver for your remote control device:

1. Launch the IR Learner software application. The application window appears; there are no open drivers.

2. Create a new or empty driver by selecting File > New. A driver document is created and its Header tab is selected.

2. Add functions by pressing the Add button in the toolbar.

NOTE: User-definable functions can be added to the driver. The names and ordering of user-definable functions can be changed at any time by double-clicking on the function to be renamed. The names and ordering of any default functions cannot be altered.

At this point the driver is populated with unlearned functions.

To learn driver functions:

1. Select those functions that are to be learned (see figure 33). Then, begin a learning session by pressing the Learn toolbar button. A series of messages and windows will guide you through the "learn" process, providing instruction on how to aim the remote, what button to press, and when to release the button.

2. Save the driver by selecting File > Save, or you can add or learn new functions.

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 Web browsers, 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).

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 36 through 41 lists the commands that the IPL T SFI244 recognizes as valid, the responses that are returned to the host, a description of each command's function, 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 34.

X1 = Specific port number (01-99) The port number will be represented as two ASCII characters (2 bytes); 00 = All ports

X2 = Command data section

NOTE: For Web encoding only - Data will be directed to specified port and must be encoded (URL encoding) if non-alphanumeric. Since data can include either command terminator, they must be encoded as follows when used within the data section: space (hex: 20) would be encoded as %20 and plus sign (hex: 2B) would be encoded as %2B.

Copyright information

(c) COPYRIGHT 2009, EXTRON ELECTRONICS IPL T SFI244, Vx.xx, 60-544-86 Thurs, 28 Jan 2010 16:29:10

The copyright message is displayed upon connecting to IP Link product via TCP/IP or Telnet. Vx.xx is the firmware version number. The unit's part number, 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 SFI244 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)

^10 = Commands that give E10 (invalid command).
^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).

Customization

You can use various methods to make the IPL T SFI244 interface perform customized functions or to alter the unit's embedded Web pages. Server Side Includes (SSIs) make it possible to send commands to the IPL T SFI244 itself, or to devices connected to its control ports. Customization is also possible by writing query strings and inserting them into Web pages stored on the IPL T SFI244.

Server Side Includes

Server Side Includes are a type of HTML comment that dynamically directs the IPL T SFI244 as to what material or files to include in the contents of a Web page or to send out to one of the unit's ports. SSIs can include embedded instructions (scripts) and style sheets (to set up page layout), and also specify what information to insert into the Web pages. These instructions run on the unit's internal Web server. Server Side Includes use Extron Simple Instruction Set (SIS) commands to ask for and display information from the IPL T SFI244, itself. When a Web page is requested, the IPL T SFI244 replaces the SSI command with the response to the SIS command.

SIS command types and syntax

SIS commands sent to IP Link-enabled products fall into two categories: host or remote.

• Host commands instruct the IPL T SFI244, itself, to act or respond.
• Remote commands send data to an external control port on the IPL T SFI244.

The basic format for a Server Side Include is as follows:

#directive parameter=x parameter=x

where

• "directive" is an instruction to the server such as include file (to include/insert the content of one document into another file) or echo var (to display a particular HTTP variable).
• The variable (x) is one or more SIS command(s) enclosed in quotation marks ("x").

See the following examples of the basic SSI command format.

Server Side Include for a Host SIS command


Examples: T memory usage. W is the Web-encoded View date substitute for the Esd key. and time.

Figure 35. SSI Syntax for a Host SIS Command In figure 35, the "N" command is used to request the IP Link product's part number and the results of the echo command are displayed in the unit's Web page(s).

Figure 36. Example of SSI "Remote" Command In figure 36, a “remote” serial command sends the word “hello” out port 1 and waits up to 50 milliseconds for a response (until three characters are received). For more information on this command, see Programmer's Guide for the Telnet and Web Browser.

Query String

A query string is a command that contains parameters or instructions for the Web server (the IPL T SFI244) to execute. The query string is contained after the question mark within a reference URL (Web address). See Query string command types and syntax. When a link is accessed on a Web page, the URL is sent to the Web server to tell it which Web page to return to the browser. Upon receiving the URL, the IPL T SFI244's internal Web server locates the query string within the URL and executes the command that it contains.

Query string command types and syntax

As with SSI formatted commands, query strings can use any valid SIS command of either type (host or remote). - Host commands instruct the IPL T SFI244, itself, to act or respond. - Remote commands send data to an external control port on the IPL T SFI244. The basic format for a query string with a link is as follows: linked text where x is the SIS command to be executed.

Figure 39. Example of a Remote Query String Command In figure 39 above, the data string that follows the pipe (|) symbol is sent to the attached controlled device on serial port #2. This string instructs an attached Extron switcher to change to input #1.

Code Examples

This section shows practical uses for both SSIs and query strings. NOTE: Before attempting to develop new Web pages, the user should have a good, working knowledge of JavaScript™, HTML, and Server Side Includes.

Example 1

In figure 40, both host SSI and remote SSI commands are used within the same Web page. You will notice six SSIs: three host commands and three remote commands.

Example 5

This example demonstrates how to send out an IR string from the IPL T SFI244. The line below shows an HTML hyperlink with an Extron IR command encoded into the URL.

<a href="index.html?cmd=W1*1*15*0ir|">Play</a> 

The ?cmd=W1\*1\*15\*0ir | is the syntax for the URL encoding of an IR command that will be sent out of IR port #1. The W and the | (pipe symbol) are used as the leading and trailing delimiters for the instruction that tells the IPL T SFI244 which port number, .eir file or function within the .eir file to send. The command also allows the programmer to define whether the IR should be sent once or continuously until stopped. The IR Learner program determines which IR function, such as play, is assigned to which number. Refer to the IR Learner program for help with this feature.

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 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, thesecharacters 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 no 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@ “At” symbol		3F	63
		40 64

Unsafe characters

URLs use some characters for "special use" in defining their syntax and these characters should be encoded. For various reasons, these characters present the possibility of being 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

A/V Device Control

Control of A/V devices can be accomplished in any of several ways once the IPL T SFI244 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 are loadable with the Web server File Manager (see Managing files).

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 SFI244) on a network. Once connected via Telnet, you can send ASCII serial commands (see Programmer's Guide for the Telnet and Web Browser) to control devices connected to the interface through both serial ports. Telnet only works in RS-232 mode.

Accessing and using Telnet

1. Click Start, then Run and type "Telnet". Click OK. The Telnet program starts (see figure 53). 2. At the command prompt, type "open" and press Enter. 3. At the < to > prompt, type the IP address of the IPL T SFI244. (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 54. Connecting to the IP Address 5. Once you are connected, you can enter serial (ASCII) commands as desired. 6. When you are through entering commands to the interface, type "quit" at the command prompt to quit Telnet.

Direct Port Access (Ports 2001 Through 2002)

Direct access allows a direct, one-to-one connection to any of the serial ports using a reserved IP port number: COM1: direct access port #2001 COM2: direct access port #2002 When a TCP session is initiated to port 2001 through port 2002, all data sent and received passes directly to and from that port without any processing. Serial port parameters should be set via Telnet connection prior to using direct access.

Using direct access

1. Access the unit via Telnet and configure the COM port parameters as desired using SIS commands (see the Command/response table). 2. Close the initial Telnet session. 3. Open a direct access Telnet session to the selected port by entering the IP address followed by a space then the port number (for example, 192.168.244.244 2001). 4. Send serial commands directly through the selected COM port to the attached A/V device. 5. Close the Telnet session to end the direct access session. NOTE: You can force the direct access session closed by logging on as Administrator and entering "Esc X1 \* 0CD←", where X1 is the selected COM port.

Port redirect

Using port redirect, either serial port can be configured as a pass-through connection, allowing data to be sent and received directly to and from the serial port back to the client (PC) without any processing. In figure 55, a MediaLink® controller connected to serial port 1 (COM1) is controlling a projector and input devices connected to serial port 2 (COM2). Port redirect is enabled with an SIS command (see the Command/response table).

Troubleshooting

Turn on output device(s) (plasma screens, monitors, projectors), the IPL T SFI244 control interface and the control devices (PC, laptop, and so on). If the output A/V device cannot be remotely controlled, check the following:

Power connections

1. Ensure that all devices are plugged in. 2. Make sure that each device is receiving power. The interface's front panel power LEDs light 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 SFI244 control interface 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). 2. Try to ping the unit by typing "ping 192.168.254.254" at the DOS command prompt, or use the Web address provided to you by your system administrator. If you get no response: a. Make sure your unit is using the appropriate subnet mask (check with your system administrator). b. Make sure your PC does not have a software firewall program which might block the IP address of the unit. 3. If contact is established with the unit, but the unit's 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, call the Extron S Sales & Technical Support Hotline if needed. See the back of this manual for the telephone number for your region.

Glossary

This section provides definitions of terms related to the IPL T SFI244. 10/100Base-T — Ethernet which 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 device's MAC or physical machine address. Custom Web page — Any file that can be loaded into an IPL T SFI244 and served by the unit's internal Web server. A custom Web page can provide control of devices attached to the IPL T SFI244 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 SFI244, 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 SFI244 functions like a little 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 an organization's network. Driver — A GC compatible package and 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 SFI244 box, 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 (.evt) is loaded onto the IPL T SFI244. 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. Floating — The condition of a device or circuit that is not grounded and not tied to any established potential. 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, the user 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® boxes to appear in the same GV, all the boxes 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 SFI244 unit. These pages provide an interface for control of devices attached to the IPL T SF unit. They communicate with the event scripts running on the box, 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 SFI244. 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 — An acronym for the HyperText Transfer Protocol (HTTP), a Web protocol based on TCP/IP, that is used to fetch HyperText objects from remote Web pages. Hysteresis (deadband) — The lag that exists between the responding parameter and the changing parameter. 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 (router, hub, interface, and so on) is connected to the Internet, a table (see ARP) relates the device's IP address to its corresponding physical (MAC) address on the LAN. Pass-through — Allows control systems to work with the IPL T SFI244 unit 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. Static IP — Refers to 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/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.
