 Installation Overview

 Mounting the IPL T CR48

 Rear Panel Features and Cabling

 Operation

Installation Overview

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

1. Turn all of the equipment off. Make sure that the input devices (such as motion

detectors and alarms), the IPL T CR48, and the output devices (such as projectors or screen lifts) are all turned off and disconnected from the power source.

2. Mount the IPL T CR48 unit (see Mounting the IPL T CR48).

3. Attach the cables (see Connecting the Hardware in the “Connection and

Conﬁguration” section.

4. Connect power cords and turn on the devices in the following order: output devices

(projector lifts, screen lifts, lighting system, and so on), IPL T CR48, serial controller or computer (PC), then input devices (DSS, cable boxes, and so on).

5. Conﬁgure the IPL T CR48 through Telnet, then access the unit using an Internet browser.

Mounting the IPL T CR48

Optional rack shelves and an assortment of mounting kits (furniture and projector mount) are available for use with the IPL T CR48 controller. See the Speciﬁcations and Part

Numbers section for the part numbers of these accessories. Read the instructions provided

with the rack shelf or mounting kit for installation procedures.

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

IPL T CR48 • Installation and Operation 3

UL Guidelines for Rack Mounting

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

1. Elevated operating ambient — If installed in a closed or multi-unit rack assembly,

the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature speciﬁed by the manufacturer [Tma = +32 to +122 °F (0 to +50 °C)].

2. Reduced air ﬂow — Installation of the equipment in a rack should be such that the

amount of air ﬂow required for safe operation of the equipment is not compromised.

3. Mechanical loading — Mounting of the equipment in the rack should be such that a

hazardous condition is not achieved due to uneven mechanical loading.

4. Circuit overloading — Consideration should be given to the connection of the

equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.

5. Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment

should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (such as the use of power strips).

Rack Mounting

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

IPL T CR48 Reset Mode Summary

Mode Activation Result Purpose and Notes

Use mode 1 to revert to the factory default version if incompatibility issues arise with user-loaded ﬁrmware.

NOTE: User-deﬁned Web pages may

not work correctly if using an earlier ﬁrmware version.

Mode 3 is useful for troubleshooting.

Mode 4 enables you to set IP address information using ARP and the MAC address.

Mode 5 is useful if you want to start over with conﬁguration and uploading, and also to replace events.

Use Factory Firmware

Run/Stop

Events

Reset All

IP Settings

Reset to Factory

Defaults

Hold down the recessed Reset button

while applying power to the IPL T CR48.

NOTE: After a mode 1 reset is

performed, update the ﬁrmware of the unit to the latest version. Do not operate the IPL T CR48 ﬁrmware version that results from the mode 1 reset. This mode temporarily resets the unit to factory default until power is recycled. If you want to use the factory default ﬁrmware, you must upload that version again.

Hold down the Reset button for about

3 seconds until the Power LED blinks once, then release and press Reset momentarily (<1 second) within 1 second*.

Hold down the Reset button for about

6 seconds until the Power LED blinks twice (once at 3 seconds, again at 6 seconds). Then, release and press Reset momentarily (for <1 second) within 1 second*.

Hold down the Reset button for about

9 seconds until the Power LED blinks three times (once at 3 seconds, again at 6 seconds, again at 9 seconds). Then, release and press Reset momentarily (for <1 second) within 1 second*.

The IPL T CR48 reverts to the factory default firmware.

Event scripting does not start if the unit is powered on in this mode. All user ﬁles and settings (such as drivers, adjustments, and IP settings) are maintained.

NOTE: If you do not want to update

ﬁrmware, or you performed a mode 1 reset by mistake, cycle power to the unit to return to the ﬁrmware version that was running prior to the mode 1 reset. Use the 0Q SIS™ command to conﬁrm that the factory default ﬁrmware is no longer running (look for asterisks following the version number).

Mode 3 turns events on or off. If the events are currently stopped following the momentary press, the power LED ﬂashes twice, indicating the starting of events. If the events are currently running following the momentary press, the Power LED ﬂashes three times indicating the stopping of events.

Mode 4:

 Enables ARP capability  Sets the IP address back to factory

default (192.168.254.254)

 Sets the subnet back to factory

default

 Sets the default gateway address to

the factory default

 Sets port mapping back to factory

default

 Turns DHCP off  Turns events off

Mode 5 performs a complete reset to factory defaults (except the firmware).

 Does everything mode 4 does  Clears driver-port associations and

port conﬁgurations

 Removes button/touchpanel

conﬁgurations

 Resets all IP options  Removes scheduling settings  Removes/clears all ﬁles from the

Contact Closure Input and Relay Connections

Contact closure input connections

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

1. Connect one end of the input cable to a 3.5 millimeter, 5-pole captive screw connector,

wired appropriately, and plug it into the rear panel input port connector of the unit.

2. Connect the other end of the input cable to the input relay device that will provide a

triggering signal.

Relay connections

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

1. Connect one end of the relay cable to an 8-pole captive screw connector, wired

appropriately, and plug it into the rear panel relay port connector of the unit.

2. Connect the other end of the relay cable to the device that will be activated when the

triggering signal is received.

Conﬁguring the Hardware

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

PC Conﬁguration

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

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

IPL T CR48 • Connection and Conﬁguration 11

Initial start up

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

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

The default Web pages that are preloaded on the IPL T CR48 provide a way to reconﬁgure the unit once it has an active network connection with IP access. These Web pages are compatible with Internet Explorer® (version 6.0 or higher). See Communication with the

Interface in the “Communication and Control” section for information on accessing and

conﬁguring the controller.

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

IPL T CR48 Interface Conﬁguration

Conﬁguring the IPL T CR48 using the ARP command

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

NOTE: To use this setup method, both your computer and IPL T CR48 must be

connected to the same LAN. Or, you can use a crossover Ethernet cable to connect the device server directly to the Ethernet card of the computer.

Use ARP to conﬁgure the IP address as follows:

1. Obtain a valid IP address for your IPL T CR48 from your network administrator.

2. Obtain the MAC address of the IPL T CR48 from the label on its back panel.

3. If the unit has never been conﬁgured and is still set for factory defaults, go to step 4. If

not, perform a Mode 4 system reset. See Resetting the Controller in the “Installation and Operation” section for detailed information on reset modes.

CAUTION: The IPL T CR48 unit must be conﬁgured with the factory default IP

address — 192.168.254.254 — before executing the ARP command, as described in the following steps.

IPL T CR48 • Connection and Conﬁguration 12

4. On the PC, access the command prompt (from the Windows desktop, click Start, then

Run, and type Telnet in the Run dialog box) then execute the arp -s command.

Enter the desired new IP address for the IPL T CR48 and the MAC address (located on the rear panel of the controller). For example:

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

Figure 10. Executing the ARP Command

5. Execute a ping command by typing ping followed by a space and the new IP address at

the command prompt. For example:

ping 10.13.170.15

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

Figure 11. Unit Response to a Ping Request

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

6. After verifying that the change was successful, enter and issue the arp -d command at

the command prompt. For example: arp -d 10.13.170.15 removes 10.13.170.15 from the arp table

- or -

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

IPL T CR48 • Connection and Conﬁguration 13

Conﬁguring the IPL T CR48 using direct PC connection

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

1. Plug one end of a CAT 5 crossover Ethernet cable into the rear panel Ethernet connector

on the IPL T CR48. See ﬁgure 7 for RJ-45 connector wiring.

2. Plug the other end of the Ethernet cable into the Ethernet port on your PC.

3. Right-click on the Network Neighborhood or My Network Places icon on your Windows

(98, 2000, NT, ME, XP) desktop and select Properties from the menu.

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

- or -

If you are using Windows 2000:

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

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

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 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 (Internet Explorer), and type

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

9. After conﬁguring your IPL T CR48, 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 CR48. These upgrade are available for download from the Extron Web site. See Upgrading the ﬁrmware in the “Communication and Control” section for more information on upgrading the ﬁrmware.

Ports Overview

Contact Closure Input Ports

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

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

+5V

Figure 12. Equivalent Circuit for Contact Closure Input

IPL T CR48 • Communication and Control 15

Relay Ports

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

1. The Port Settings default Web page found under the Configuration tab (ﬁgure 16)

2. Telnet

3. An event script running on the IPL T CR48

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

Telnet allows you to send SIS

Web Browser, later in this section, to turn the relays on or off directly.

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

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

Communication with the Interface

Web Server

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

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

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

Programmer’s Guide for the Telnet and Web Browser

Using the Command/Response Table

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

command/response table show the proper implementation in a Telnet or Web browser

session.

NOTE: For Web browsers, all non-alphanumeric characters must be represented as their

hex equivalent such as %xx where xx equals the two character representation of the hex byte that needs to be sent (for example, a comma would be represented as %2C).

Telnet

Web Browser

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

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

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

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

NOTE: With Telnet you can use either the “Escape” character or the “W” character,

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

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

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

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

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.

IPL T CR48 • Communication and Control 25

Error responses

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

E10 — Invalid command E12 — Invalid port number E13 — Invalid parameter E14 — Not valid for this conﬁguration E17 — System timed out E22 — Busy E24 — Privilege violation E25 — Device not present E26 — Maximum number of connections exceeded E27 — Invalid event number E28 — Bad ﬁlename/ﬁle not found E31 — Attempt to break port pass-through when not set (A user or software attempted to disable the port redirect feature when it wasn’t already set or active.)

URL Encoding

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

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

Alphanumerics 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.

IPL T CR48 • Communication and Control 26

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.

Device Control

Custom Web Pages

Telnet (Port 23)

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

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

Web page development can be done with a Web site development tool such as Frontpage or Dreamweaver. Custom Web pages can be loaded with the Web server File Manager (see Managing ﬁles earlier in this section).

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

Browser earlier in this section) to control devices connected to the IPL T CR48.

Accessing and using Telnet

1. From the Windows desktop, click Start, then Run.

2. In the Run dialog box, type Telnet.

3. Click OK. The Telnet program starts (ﬁgure 22).

Figure 22. Telnet Command Prompt

4. At the command prompt, type open and press Enter on the keyboard.

5. At the <to> prompt, type the IP address of the IPL T CR48. (The default IP address is

192.168.254.254, but it may have been changed in the setup or conﬁguration process. If it was changed, use the new address.) Telnet defaults to port 23.

IPL T CR48 • Speciﬁcations and Part Numbers 36

Glossary

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

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

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

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

Custom Web page — Any ﬁle that can be loaded into an IPL T CR48 and served by the unit’s internal Web server. A custom Web page can provide control of devices attached to the IPL T CR48 without use of the GlobalViewer® (GV) or Global Conﬁgurator (GC). This is true with or without an accompanying event script. Any number and size of graphics can be used, but if they are too large to ﬁt on the IPL T CR48, you can write your Web page so that they can be served from another Web server. If you install Microsoft® Internet Information Services (IIS) on your desktop, you can serve any page on its hard disk. The IPL T CR48 functions like a small computer with a Web server — you can use it for various Web tasks.

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

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

Ethernet — A network protocol that uses MAC addresses instead of IP addresses to

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

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

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

IPL T CR48 • Glossary 37

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

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

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

IP address — A unique, 32-bit binary number (12-digit decimal number, xxx.xxx.xxx.xxx) that identiﬁes each sender and each receiver of information connected to a LAN, WAN, or the Internet. IP addresses can be static (see “Static IP”) or dynamic (see “DHCP”).

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

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

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

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

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

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

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

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

Telnet — A utility available on most PCs that allows the computer system to communicate with one of its remote users or clients. A user who wishes to access a remote system initiates a Telnet session, using the address of the remote client. The user may be prompted to provide a user name and password if the client is set up to require them.

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