SERVSWITCH™ BRAND FIBER KVM EXTENDERS

5.1.1 CPU

The ACS235A Extender supports IBM PC compatible desktop CPUs; it does not support laptops. A CPU must have these kinds of interfaces to work fully with the ACS235A Extender:

•Video: VGA, SVGA, XGA, or XGA-2. (Also supports most CPUs that output RGB.)

•Keyboard: IBM PS/2 style (6-pin mini-DIN). (With the included keyboard-port adapter, will also support CPUs with PC/AT [5-pin DIN] keyboard ports.)

•Mouse: IBM PS/2 style (6-pin mini-DIN). (With the included mouse-port adapter, will also support CPUs with RS-232 serial [DB9] mouse ports.)

•Parallel (optional): IBM PC style (Centronics compatible). This interface has strict limitations; see Section 5.1.5.

The ACS236A Extender supports most Sun compatible CPUs that output VGA video on an HD15 connector or legacy Sun Video on a 13W3 connector.

5.1.2VGA MONITOR

The VGA red, green, and blue color signals are analog values in the range of 0 to

0.8Vpp. The signals have no DC offset; this means that the black level meets ground (that is, that the zero-signal [black] voltage level of the color leads is equivalent to the voltage level of the color-ground leads). The horizontal and vertical synchronization signals are TTL signals with various polarities, depending on the selected monitor resolution (for example, text-only, 640 x 480, 800 x 600, etc.). For transmission across the fiber cable, the SYNC signals are added to the color-signals and separated again at the receiver.

CAUTION!

If you use a “Plug and Play” monitor, you will have to configure the video settings manually.

5.1.3RGB MONITOR OR LEGACY SUN MONITOR

The RGB red, green, and blue color signals are analog values in the range of 0 to

0.8Vpp. The composite (horizontal + vertical) synchronization signal is usually added to the green signal, although some devices also add synchronization or other information to the red and/or blue signals. Normally the color signals have a DC offset, or at least the green/SYNC signal does; this means that DC voltage is added to the lead so that even when there’s no color signal present (when the screen is black), the color lead with the DC offset has higher voltage than the ground lead. These signals must be clamped at the remote end, for linear amplification in stages that follow.
