Figure 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 switcher is ideal for displaying images on projectors with limited display resolutions,
such as LCD projectors, DLP projectors, and plasma projectors.
The switcher features built-in test patterns to aid in monitor or projector set-up and
evaluation.
The switcher is housed in a rack-mountable, 3U high, 17.5 inch wide, metal enclosure. The
ISM has an internal 100VAC to 240VAC, 50/60 Hz, 30 watts power supply that provides
worldwide power compatibility.
