Figure 1. Typical ISS 408 Integration Seamless Switcher Application
The ISS receives and outputs audio on 5-pole captive screw connectors. The audio can
be switched with cross fading; the previous audio channel fading out and the new audio
channel fading in.
For upscaling, the ISS 408 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 ISS 408 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, plasma projectors, and (with an optional DVI card)
a DVI display or projector.
The switcher features built-in test patterns to aid in monitor or projector setup and
evaluation.
The switcher is housed in a rack-mountable, 3U high, 17.5” wide, metal enclosure. The
ISS has an internal 100 VAC to 240 VAC, 50/60 Hz, 30 watts power supply that provides
worldwide power compatibility.
