Figure 1-1— Typical ISM 482 Integration Scaling Matrix Switcher
application
The ISM receives and outputs the stereo audio on 5-pole captive screw connectors.
For upscaling, the ISM 482 converts the horizontal and vertical sync timing and the
number of lines of the lower-resolution video input to match the native resolution
of the display. This produces an undistorted, brighter picture than an unscaled
input would.
For downscaling, the ISM 482 accepts any computer resolution, up to 1600 x 1200,
with horizontal scan rates up to 100 kHz and vertical scan rates up to 120 Hz, and
converts the input to match the native resolution of the display.
The switchers are ideal for displaying images on projectors with limited display
resolutions, such as LCD projectors, DLP projectors, and plasma projectors.
The switchers feature built-in test patterns to aid in monitor or projector set-up and
evaluation.
The switchers are housed in a rack-mountable, 3U high, 17.5” wide, metal
enclosure. The ISM has an internal 100VAC to 240VAC, 50/60 Hz, 30 watts
autoswitchable power supply that provides worldwide power compatibility.
