SERVSWITCH™ AND SERVSWITCH ULTRA™

The IBM and multiplatform ServSwitches will support SVGA (Super VGA) video,

but with original Serv cables the video quality will decrease markedly at higher

resolutions and distances. Table 4-2, below, illustrates this. The distances in the

table are total cable lengths measured from the CPU to the monitor. The table

assumes that one ServSwitch is between the CPU and monitor; in a cascaded

application with a ServSwitch and one or more submasters between the CPU and

monitor, video quality will always be lower.

This table also applies to Mac video in ServSwitch systems in which the Mac

versions of the original Serv cables (our product codes EHN210 and EHN215)

have been installed.

Quality 3 = Near perfect; screen defects are not conspicuous

Quality 2 = Good to very good; images are clear; there are small reflections around

text lettering depending on the color; screen defects are sometimes

conspicuous

Quality 1 = Fair to poor as distance increases; images run from slightly fuzzy to

badly smeared; text runs from fuzzy but readable to completely

washed out
