About this Manual
This manual contains installation, configuration, and operating information for the
Extron ISS 108 and ISS 408 Integration Seamless Switchers.
The ISS 108 and ISS 408 are similar in function and operation; the differences exist
in scaling capabilities. In this manual, the terms "switcher" and "ISS" are used
interchangeably to refer to either model, except where differences exist, in which
case the specific model is noted.

About the Switcher
The Extron ISS 108 and ISS 408 are eight-input, scaling, video and stereo audio
seamless switchers. Figure 1-1 shows a typical ISS 408 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. The ISS seamlessly switches among the input sources without a loss
of sync. The ISS can also mask the switch between sources with a dissolve effect
for a professional look.
Each video input is individually configurable to allow for different video formats.
The ISS 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 an liquid crystal display (LCD) projector, digital
light processor (DLP) projector, plasma display, or digital visual interface (DVI)
device.
The ISS provides two separate outputs: the program output and the preview output.
The program output is the picture the audience sees. The preview output allows
the switcher operator to view the image before it is sent to the program output.
With an optional DVI output card, the ISS converts the scaled image to DVI as an
additional program output.
The switcher inputs all valid video signal formats on eight sets of five BNC
connectors. The ISS 408 scales the input up or down to any of 40 output
resolutions and rates. The ISS 108 scales the inputs to any of 20 resolutions and
rates. Either switcher outputs the scaled video, as RGBHV or RGBS, on two sets
(program and preview) of connectors. The program and preview outputs each
consist of five BNC connectors and a 15-pin HD connector. The BNC connectors
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 ISS 408
features HDTV 576p, 720p, 1080p, and 1080i outputs.
