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 TM based networks.

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

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 ™ Rack Shelf

Kit (Extron part #60-190-20) or a Universal 1U Rack Shelf

1-2 IPL T SF24 and IPL T SFI244 • Introduction

(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.

IPL T SF24 and IPL T SFI244 • Introduction 1-3

Easily configured and controlled —

•

•

Using a standard Web browser (Internet Explorer V5.5,

Netscape V6.0 or higher) and Web-based interface.

Using a standard Telnet client application.

• Requires no centralized processor to operate within a system.

Choice of mounting options — Can be mounted under a desktop or podium, on a projector mount, or on a rack shelf.

Resetting the unit

There are five reset modes available by using the Reset button

(

2

) 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.

CAUTION The reset modes listed below (with the exception of

Mode 2) will close all open IP and Telnet connections and close all sockets.


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.

Mode 3 — Holding the Reset button until the Power LED blinks once (3 seconds) followed by a momentary

(<1 second) press will turn events either on or off, depending on the current state of the events:



• If the events are currently stopped following the momentary (<1 second) press, the Power LED will

flash twice indicating the starting of events.

or

• If events are currently running following the momentary (<1 second) press, the Power LED will

flash three times indicating the stopping of events.

Each flash will last for .25 seconds. Nothing happens if the momentary press does not occur within 1 second.

Mode 4 — Holding the Reset button until the Power LED blinks twice (6 seconds) followed by a momentary (<1 second) press will reset IP settings. The Power LED will blink four times in quick succession, confirming a Mode 4 reset. This mode will

1. Enable ARP program capability.

2. Set IP back to factory IP.

3. Set Subnet back to factory default.

4. Set Gateway back to factory default.

5. Set port mapping back to factory default.

6. Turn DHCP off.

7. Turn events off.

Nothing happens if the momentary press does not occur within one second.

Mode 5 — Holding the Reset button until the Power LED blinks three times (9 seconds) followed by a momentary

(<1 second) press will cause an absolute system reset back to factory default conditions. Nothing happens if the momentary press does not occur within 1 second. The power LED will blink four times in quick succession, confirming a Mode 5 reset.

IPL T SF24 and IPL T SFI244 • Connection and Configuration

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 interface 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.



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 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.

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

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 3-5 — 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


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.

Configuring the IPL T using direct PC connection

This type of connection is used initially to connect to and configure the IPL T unit. 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 unit. Refer to figure 2-7 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. (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’s 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:

. . .

6.

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

7.

Save the changes and exit the Network setup. Reboot the

PC, if required, for the changes to become effective.

8.

Launch your Web browser (Netscape Navigator or Internet

Explorer), and type “http://192.168.254.254/index.html” in the address box. The IPL T default Web page will be displayed. Refer to IPL T interface configuration, in this chapter, for information on configuring your unit.

9.

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

Firmware upgrades

Firmware upgrades will become available periodically, as improvements are made to the versatility and functionality of the IPL T interface. These upgrades will be available for download from the Extron Web site. For information on upgrading the firmware, see Upgrading the firmware in chapter 4.

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.

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.

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

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 RS-

232, 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. Since RS-232 is the most common control interface encountered, this port configuration allows for quick termination.



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).

6.

Select the port the IR command will be sent to.

7.

Execute the IR command by clicking the command link.

The IR LED on the front of the IPL T SFI244 unit will blink a green light verifying the sending of the IR command.



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.

Figure 4-13 — Example of the default Web interface of an .eir file

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.

c.

Click Save to keep changes to recipient e-mail addresses and file names.

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

6.

Obtain your gateway IP address from your system administrator.

7.

Click System Settings on the menu on the left side of the window.

8.

Within the System Settings screen (figure 4-10) place the gateway IP address into the Gateway IP Address field.

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

For detailed information on creating monitoring and scheduling scripts and software, see the Global Viewer Software User’s Guide.

Upgrading the firmware

Firmware upgrades will become available periodically, as improvements are made to the versatility and functionality of the IPL T interface. These upgrades will be available for download from the Internet.

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


To upgrade the firmware:

After ten files have been loaded, additional file management pages will appear in the page navigation area (on the right side of the screen).

To delete unwanted files:

1.


2.

Find the file you wish to delete under the Files list.

3.

Click the Delete button of the file to be deleted. If you wish to delete additional files, wait for the screen to refresh before clicking the delete button of the next file.

If you wish to delete all files, click the Delete All button. The file count will revert to 0 and all subsequent pages will be deleted.

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.

Figure 4-19 — Creating a new driver

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.

Figure 4-20 — Selecting driver functions

For more details about IR learning, refer to the IPL T IR Learner

User’s Manual.

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

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 (e.g., a comma would be represented as %2C).

Telnet

Escape (Hex 1B)

Web Browser

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

(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

Encoding later in this chapter.

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.

Symbol definitions are shown below. An ASCII to HEX conversion table is also provided in figure 4-21 (below).

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 respond.

2.

Remote commands pass data to an external control port on an IP Link product.

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

Server Side Include Using the Host SIS command

Figure 4-22 — Example of SSI “host” command

In figure 4-22 above, the “N” command is used to request the IP

Link product’s part number.

Elements


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”.

The query string in figure 4-24 below will turn off DHCP on the

IP Link device.

Figure 4-25 — Example of a remote query string command

In figure 4-25 above, the data string that follows the pipe ( ) symbol will be sent to the attached controlled device on serial port #2. This string will instruct an attached Extron switcher to change to input #1.

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.

Figure 4-26b — Resulting HTML source code served by an IP Link Web server

Notice, in figure 4-26b, that the commands executed by the IP

Link box in response to SSI references have been replied to, and were implemented when the Web page was served to the browser as seen below.

Example 2

The example below (figure 4-27a) shows how a simple hyperlink and a remote query string can be used to build a Web page that can control a device.

<html>


<h2>HTML Example 2</h2>

The next example shows how the flex I/O outputs can be controlled using a query string and the SIS commands.

<html>


<h2>HTML Example 3</h2>

<body>

The following lines demonstrate how to send commands to an IP Link Product:



<a href="index.html?cmd=1*1]">Set Digital Output On</a>

 

<a href="index.html?cmd=1*0]">Set Digital Output Off</a>



</body>

</html>

Figure 4-28a — HTML source code using a query string

<html>


<h2>HTML Example #4</h2>

<body>



<script> var ioState1 = "" var ioState2 = ""

if ((ioState1 == 1) && (ioState2 == 0)) {

document.write('Input #1 Selected')

}

else if ((ioState1 == 0) && (ioState2 == 1)) {

document.write('Input #2 Selected')

}

else {

document.write('No Input Selected')

}

</script>





<a href="index.html?cmd=3*25*3]">Select Input #1</a>

 

<a href="index.html?cmd=4*25*3]">Select Input #2</a>



</body>

</html>

Figure 4-29a — HTML source code showing server side includes

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 4

The flex I/O can also be configured as an input. In the next example, two inputs are connected to a System 8 Plus switcher.

Using JavaScript, the status of the digital inputs can be checked and the appropriate message displayed for the user.





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>Example 5</h2>

<body>



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. This IR driver must be loaded on the IPL T SFI244 in order to send out the string.





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





<a href="index.html?cmd=W1*1*32*0ir|">Stop</a>



</body>

</html>

Example 6

The example below (figure 4-31a) shows how you can use

JavaScript to parse the response from a CrossPoint 8HVA switcher and produce a formatted Web page.

<html>

<head><title>Example 6</title>

<script language="javascript"> xOut1 = ""; xOut2 = ""; xOut3 = ""; xOut4 = "";

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

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.

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.

Figure 4-32 — Telnet command prompt


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.

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).



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

X1

* 0CD ”, where

X1

is the selected COM port.

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).

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 chapter 3).

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 3 Sales &

Technical Support Hotline if needed.

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.

B-2 IPL T SF24 and IPL T SFI244 • Glossary

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.
