About this Manual

This manual contains installation, configuration, and operating information for the Extron ISM 182 and ISM 482 Integration Scaling Matrix switchers.

The ISM 182 and ISM 482 are similar in function and operation; the differences exist in scaling capabilities. In this manual, the terms “switcher” and “ISM” are used interchangeably to refer to either model, except where differences exist, in which case the specific model is noted.

Chapter 1 identifies the switcher’s features.

Chapter 2 details how to install the switcher.

Chapter 3 describes how to operate the switcher and use all of its features.

Chapter 4 provides information about programming and operating the switcher under RS-232 control, such as from a PC or host controller.

Chapter 5 details the Extron control software for Windows, which allows you to operate the switcher from a PC in a graphical environment.

Chapter 6 details operation of the switcher using an Ethernet browser.

Appendix A is a high-level Internet protocol (IP) primer (Ethernet and Telnet).

Appendix B lists the switcher’s specifications and pertinent part numbers and provides procedures for replacing the switcher’s firmware.

About the Switcher

The Extron ISM 182 and ISM 482 are eight-input, two-independently-scaled-output, video and stereo audio matrix switchers. Figure 1-1 shows a typical ISM 482 application. The switchers accept high resolution RGB video, YUV (component) video, S-video (Y/C), and composite video inputs; scale the inputs; and output RGBHV or RGBS video and stereo audio. Triple-Action Switching™ (RGB delay) blanks the screen during the switch to prevent distracting video glitches. The switchers’ two independent scalers permit differing video formats on each input to be displayed in different resolutions on different projectors.

Each video input is individually configurable to allow for different video formats. The ISM allows analog RGBHV, RGBS, RGsB, and RGBcvS video, component video, S-video, and composite video signals to be displayed on a device with a fixed resolution and aspect ratio, such as a liquid crystal display (LCD) projector, digital light processor (DLP) projector, or plasma display.

The ISM provides two separate outputs. The selected input can be switched to either or both outputs.

The switchers input all valid video signal formats on eight sets of five BNC connectors. The ISM 482 scales the input up or down to any of 40 output resolutions and rates. The ISM 182 scales the inputs to any of 20 resolutions and rates. Either switcher outputs the scaled video, as RGBHV or RGBS, on two sets of output connectors, consisting of five BNCs and a 15-pin HD connector. The BNCs and 15-pin HD connector share identical outputs. Several of the output resolutions and rates include Extron’s Accu-RATE Frame Lock™ (AFL™), a proprietary technology that locks the output frame rate to the input rate, solving the image tearing problem that can result from different input and output rates. The ISM 482 features HDTV 576p, 720p, 1080p, and 1080i outputs.
