Introduction

About this Manual

This manual contains information about the Extron IPL T SF24 (Extron part #60-544-02) and the IPL T SFI244 (Extron part #60-544-06) Ethernet control interfaces. It includes information on how to install, configure, and operate each system. When information in this manual applies to both models, they may be referred to generally as an IPL T unit or interface.

About the IPL T SF24 and SFI244 Interfaces

The Extron IPL T interfaces (SF24 and SFI244) are Ethernetbased control interfaces designed to be used as one of many nodes in a distributed control system environment, or as standalone control interfaces allowing legacy products to link to today’s IP Tools

The IPL T SF24 has two serial ports and four Flex I/O ports. Each serial port is available on both 9-pin D and captive screw connectors. The 9-pin D connectors support RS-232, RS-422, and RS-485. The captive screw connectors support RS-232 only. The four Flex I/O ports are on a 5-pole captive screw connector which provides one pole for each port, as well as a fifth for ground. All serial ports are fully software configurable through the network using either the Web-based interface or a Telnet connection.

The IPL T SFI244 has one 10-pole, 3.5 captive-screw connector for the two bidirectional COM ports and the four digital I/O ports. It also has one 8-pole, 3.5 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 will support the RS-232 protocol only (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 interfaces can host their own Web pages, stored in flash memory within the devices, and can accept power over a LAN (local area network). They will support Telnet, SMTP (simple mail transfer protocol), ICMP (Internet control message protocol) or ping, and DHCP (dynamic host configuration protocol).

The IPL T interfaces are 1U high and one quarter rack wide. They are rack-mountable, using either a VersaTools Kit (Extron part #60-190-20) or a Universal 1U Rack Shelf

based networks.

The 5-pole captive screw serial ports support only RS-232.

™

Rack Shelf

(Extron part #60-190-01). They can also be mounted under a desk or podium top, or on a projector mount.

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

Features

Distributed system architecture — A decentralized architecture

insures fault-tolerance throughout the system and standalone reliability.

IR remote control — Infrared remote control allows “learning”

of commands to control A/V devices.

Easy component configuration — Using the Global Viewer

software allows point-and-click component configuration and control.

Power over LAN — Accepts power over the LAN (802.3af

compliant) and provides s a 12VDC power supply, if required.

High speed — Provides constant high speed data throughput,

with a 6 Mbit/second transfer rate.

User customizable — Tailor the on-board Web pages with

advanced programmability, e-mail alerts, and storage to suit your needs and requirements. Or develop your own Web pages using the Global Viewer application software.

Direct port access — Use existing software programs to control

a device that has no Ethernet support. Any existing Extron product with a serial control port can be interfaced with a LAN.

Built-in multilevel security — User controls access to the

devices attached to the interface. Two levels of password protection provide appropriate security.

Easily connected — Serial ports on 3.5 mm, captive screw

connectors, and RJ-45 male auto-sense 10/100 Mbs Ethernet LAN connection.

I/O ports — Can be used to sense when a switch or relay has

been activated (input). Can also be used to activate external relays for power, screens, or projector lift controls (output).

IR ports (SFI244 only) — Allow control of up to 16 devices,

with four IR emitters per port.

Resetting the unit

There are five reset modes available by using the Reset button (

) on the front panel. The Reset button is recessed, so use of a

pointed stylus, ballpoint pen, or Extron Tweeker is suggested.

CAUTION

Review the reset modes carefully. Use of the wrong reset mode may result in unintended loss of flash memory programming, the reassignment of ports, or a unit reboot.

If the Reset button is continuously held down, every 3 seconds the LED will pulse (blink) and put the unit 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’s the last mode. The following modes are listed as separate functions, not as a continuation from Mode 1 to Mode 5.

Mode 1 — Holding the Reset button while applying power will

default the unit back to the base firmware that shipped with the unit from the factory. Event scripting will not start when the unit is powered on in this mode. This allows you to recover a unit that has incorrect code or updated firmware running. All user files and settings are maintained. User Web pages may not work correctly if using an earlier firmware version.

Mode 2 — Momentarily (<1 second) pressing the Reset button

and typing three “+’s” into any available COM port on the IPL unit (e.g., “+++” within 2 seconds of the momentary press) will enable the connected COM port to be used as a console port to send SIS commands. If the three “+’s” are not entered in the 2 second time frame, the COM port will remain or return to being a control port only.

There will be no LED indication. If the three “+’s” are entered within the 2 second time frame, the copyright message below will be shown.

This will indicate that you have successfully enabled the COM port.

Configuring the Hardware

To function together properly, both the controlling PC and the IPL T interfaces must be configured correctly: the PC must be network-capable, with the proper protocols installed and the hardware configured correctly, and the interface must be set to recognize and accept commands and 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’s 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 unit 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 interface for the first time, there are two ways to set up the IP address:

1. Use the ARP command method.

2. Use the direct PC method.

The default Web pages that are pre-loaded on the IPL T interface provide a way to reconfigure the IPL T unit once it has an active network connection with IP access. These Web pages are compatible with Netscape Navigator (version 6.0 or higher), or Internet Explorer (version 5.5 or higher). See Communication with the Interface in chapter 4 for information on accessing and configuring the interface.

Once the interface has been reconfigured, an Ethernet (intranet or Internet) connection can subsequently be used to contact or control it. Refer to Ethernet connection in this chapter for additional information.

IPL T SF24 and IPL T SFI244 • Connection and Configuration

Configuring the IPL T using the ARP command

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

IPL T SF24 and IPL T SFI244 • Connection and Configuration

3-5

Connection and Configuration, cont’d

In order to use this setup method, both your computer and IPL T interface must be connected to the same LAN. Or, you may 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 interface from

your network administrator.

2. Obtain the IPL T unit’s MAC address (UID #) 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. For detailed information on reset modes, see Resetting the unit in Chapter 2.

CAUTION

4. Access the MS-DOS 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 unit. For example:

arp –s 10.13.170.15 00-05-A6-00-0A-90

Your IPL T unit must be configured with the factory default IP address — 192.168.254.254 — before executing the ARP command, as described below.

After issuing this command, the unit will change to the new address and start responding to the ping requests, as shown below. The IPL T 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.

Figure 3-6 — Unit response to a ping request

6. After verifying that the change was successful, issue the

arp –d command at the DOS prompt. For example: arp –d 10.13.170.15 will remove 10.13.170.15 from the arp

table or arp –d* will remove all static IP addresses from the arp

table.

Figure 3-5 — Executing the ARP command

5. Execute a ‘ping’ command by typing your new IP address

at the command prompt. For example:

ping 10.13.170.15

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, relays, etc. 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 Web Server (see figure 4-1 below; also see Establishing or changing system or port settings later in this chapter) or by dynamically using the Simple Instruction Set commands (see the Command/Response Table for Simple Instruction Set commands in this chapter) via Telnet, scripts or Web pages.

Digital input

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

Figure 4-3 — equivalent digital input circuit

The Digital Input mode has two configurable options:

1. The ability to turn on an internal pull-up resistor to

+5VDC (shown below as SW2)

2. Adjustable detection threshold voltages The default threshold voltages follow standard TTL logic:

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

If the integrator selects threshold voltages that are more than

0.1V apart, a deadband, or hysteresis, will be established. In the example below, the lower threshold voltage is set at

+6VDC and the upper threshold is set at +16VDC. The colored bands show state changes on the logical outputs.

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

Digital output

When a Flex I/O port is configured as a digital output, it is set to offer 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 250mA 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 +5VDC.

Bidirectional serial control interface ports

The IP Tools 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 thirdparty devices. The most common serial control formats are RS232, RS-422, and RS-485. Within the IPL T products, there are two different implementations for the serial control ports: the 9-pin D connector and the captive screw connector.

9-pin D Connectors — On some IPL T units, serial control is

accessed through a 9-pin D connector. In this configuration, all three control formats are available and fully software configurable. By selecting the RS-232 format, hardware handshaking (RTS, CTS) is also available. The RS-232 connection uses the same industry standard interface pin-out as found on standard PCs. If selecting either RS-422 or RS-485 formats, verify proper wiring as detailed in figure 2-8. These two formats do not have an industry standard pin-out and will vary from device to device.

Captive Screw Connectors — On other IPL T units, several 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.

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 115Kbs. Using the Simple Instruction Set (SIS) commands found in the Command/ Response Table for Simple Instruction Set later in this chapter, 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 interface. Web browsers such as Netscape Navigator (version 6.0 or higher), or 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 interface. 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 unit (but not when you initially access the Web server, since no passwords have been established). Your level of control over the interface will depend on the password you enter in this password screen. If you enter the administrator’s password, you will have control of all matters of configuration. If you enter a user password, you will be restricted to control of A/V devices and viewing status.

Accessing and using the Web server

Logon and 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 interface

configuration in chapter 3) in the address field at the top of

the screen and press the Enter key. The Password window (figure 4-8) 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).

Setting and changing your passwords

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

To set or change the passwords:

1. Click the Passwords link on the menu (on the left side of

the window) and the Passwords screen (figure 4-14) is displayed.

2. Enter the passwords for administrator and/or user, then

reenter the same passwords to confirm.

3. Click the Submit button to enter the changes, or click

Cancel to revert to previous settings. If the fields are blank, no passwords have been assigned.

To clear a password, enter a single space, repeat the entry, and press ‘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 interface, you can write an e-mail alert with a message corresponding to that event or task (e.g., a timer notification indicating it’s 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 E-mail Alerts page:

1. Click E-mail Alerts on the menu (on the left side of the

window) and the E-mail Alerts screen (figure 4-15) is displayed.

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. For instructions on how to do this,

see Accessing and using Telnet later in this chapter.

2. Use the “Send e-mail” SIS command to send the alert to

the e-mail address of a numeric mailbox (see figure 4-15). Refer to the Command/response table for Simple Instruction Set (SIS) commands later in this chapter for specific command code.

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

Esc 4 SM

File names must end with an .eml extension.

Due to the 7 character limit for full file names, it’s advised that you use numeric titles (e.g., 1.eml, 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 upgrade the firmware:

1. Click Firmware Upgrade on the menu (on the left side of

the window) and the Firmware Upgrade screen (figure 4-16) is displayed.

IR Learning (SFI244 only)

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 the Global Viewer to assist in controlling commonly used functions.

During IR learning, the user must hold the device remote between 2” and 12” away from the IR pick up device. See figure 4-18 for an example.

Creating a driver with the IR Learner software

In order 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 unit. In other words, you must create a driver for your remote control device. You have the option of creating a new, custom driver or manipulating an existing driver. Both can be accessed or created through the IR Learner software.

To create a driver for your remote control device, do the following:

1. Launch the IR Learner software application. The

application window will appear; there will be 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.

3. Edit the Header fields (figure 4-19), the most important of

which is Type. The driver will be populated with a default set of commands according to the selected device type. A device type of “Other” creates an empty driver with no functions.

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

User definable functions may be added to the driver. The names and ordering of user definable functions may be changed at any time by double clicking on the function to be renamed. The names and ordering of any default functions can not 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 4-20). Then begin a learning session by pressing the learn toolbar button. A series of messages and windows will guide the user through the “learn” process, instructing the user 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.

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 (e.g., 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

With Telnet you can use either the “Escape” commands or the “W” commands, and the carriage return or the pipe character. With the Web browser, you are required to use the “W” commands and the pipe character.

In either method {Data} = Data will be directed to a specified port and must be encoded if non-alphanumeric.

The table on pages 4-23 through 4-29 lists the commands that the IPL T interface recognizes as valid, the responses that are returned to the host, a description of the command’s function, or the results of executing the command.

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

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 shows the proper implementation in a Telnet or Web browser session.

For Web browsers: all non-alphanumeric characters

Customization

In the IPL T interface family, varying degrees of customization are possible. Server side includes make it possible to obtain information from the unit and display the information on Web pages. URL encoding allows you to send information and commands to the unit to change its configuration or provide you with feedback.

Server side includes

Server sides includes (SSIs) 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 Extron’s Simple Instruction Set (SIS) to communicate commands to the products or attached control devices. Using SSIs, custom pages can be designed and displayed, with IPL T interface 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.

The SIS instructions sent to IP Link-enabled products fall into two categories: “host” or “remote”.

1. Host commands instruct the IP Link product to act or

2. Remote commands pass data to an external control

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 4-23 — Example of SSI “remote” command

In figure 4-23 above, a “remote” serial command sends the word “hello” and will wait up to 50ms for a response (until three characters are received). For more information on this command, refer to the Command/response table for Simple Instruction Set (SIS) commands earlier in this chapter.

Query string

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”>Input #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 IP Link product will remove and execute.

As with SSI formatted commands, query strings can use any valid SIS command—either “host” or “remote”.

Code examples

This section shows practical uses for both SSIs and query strings.

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 4-26a, 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.

Using the SSI to assign the state of input 1 and 2 allows the JavaScript code to determine which switcher input is selected. This example also demonstrates using a URL query string in conjunction with the pulse I/O command to allow the user to switch the System 8 with a 250 ms closer.

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 box 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. See the IR Learner program for help with this feature.

<html> <head><title>Example #5</title></head> <h2><b>Example 5</b></h2> <body> <p> This example demonstrates how to send out an IR string from an IR file (1.eir) on IR Port #1 from the IPL T SFI244.

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 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

special characters

reserved characters

IPL T SF24 and IPL T SFI244 • Communication and Control

0-9 a-z A-Z

$ _ _ . + ! * ( ) ,

; / ? : @ = &

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.

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.

IPL T SF24 and IPL T SFI244 • Communication and Control

Communication and Control, cont’d

A/V Device Control

Control of A/V devices may be accomplished in any of several ways once the IPL T interface 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 earlier in this chapter).

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 interface) on a network. Once connected via Telnet, you can send ASCII serial commands (see the Command/response table earlier in this chapter) 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, then type in “Telnet” and click OK.

The Telnet program will start (see figure 4-32).

2. At the command prompt, type “open” and press Enter.

3. At the < to > prompt, type the IP address of the IPL T unit.

(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 will default to port 23.

4. If passwords were set up for the connected system, you

will be prompted to log in as Administrator or User. Otherwise the system will respond with a <cr/lf>.

Figure 4-33 — 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 will pass directly to and from that port without any processing. Serial port parameters should be set via a Telnet connection prior to using direct access.

Figure 4-32 — Telnet command prompt

IPL T SF24 and IPL T SFI244 • Communication and Control

Using direct access

1. Access the unit via Telnet and configure the COM port

parameters as desired using serial commands (see the Command/response table earlier in this chapter).

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 (e.g., 192.168.244.244 2001).

IPL T SF24 and IPL T SFI244 • Communication and Control

Communication and Control, cont’d

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.

You can force the direct access session closed by logging on as administrator and entering “Esc where

is the selected COM port.

* 0CD ”,

Port redirect

Using the port redirector, 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 4-34, a MediaLink controller connected to serial port 1 (COM1) is controlling a projector and input devices connected to serial port 2 (COM2).

Port redirect can also be used in conjunction with Extron’s Serial Link Software (refer to the Serial Link Software User’s Guide) to set up virtual COM ports on a PC or laptop, to monitor COM port data and pass it to the LAN, or to set up a projector or other RS-232 controlled A/V devices via the IPL T interface. Port redirect is enabled with an SIS command (see the Command/ response table earlier in this chapter).

Troubleshooting

Turn on output device(s) (plasma screens, monitors, projectors), the IPL T control interface and the control devices (PC, laptop, etc.).

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 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 (refer to Connecting the Hardware, in

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

Glossary

10/100Base-T is Ethernet which uses unshielded twisted pair (UTP - Cat 5, etc.) 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) is a protocol which assigns an IP address to a device based on the device’s MAC or physical machine address.

Custom Web page is any file that can be loaded into an IPL box and served by the IPL’s internal Web server. A custom Web page can provide control of devices attached to the IPL without use of the Global Viewer (GV) or Global Viewer Configurator (GVC) software. 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, 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 functions like a little computer with a Web server—you can use it for various Web tasks.

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

Driver is a Global Viewer Configurator (GVC) compatible package. It includes the event script that controls devices.

Ethernet is 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 is a program that runs on an IPL 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). The Global Viewer Configurator performs this compilation. The compiled result (.evt) is loaded onto the IPL box. 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 box.

Floating is the condition of a device or circuit that is not grounded and not tied to any established potential.

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

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

HTTP is 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) is the lag that exists between the responding parameter and the changing parameter.

Internet Protocol (IP) is the protocol or standard used to send information from one computer to another on the Internet.

IP address is 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 net mask is 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 rest of the network or the Internet.

Media Access Control (MAC) Address is a unique hardware number given to devices that connect to a network such as the Internet. When your computer or networking device (router, hub, interface, etc.) is connected to a LAN or 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 and provides a link between two ports.

Ping is 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 is 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.

Powered Ethernet is a standard (802.3af) that provides power to network devices by utilizing the existing Ethernet connection, thereby eliminating the need for additional, external power supplies.

Static IP refers to an IP address that has been specifically (instead of dynamically—see DHCP above) 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) is 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 is 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.
