“R2” SERVSWITCH
Panel Label Connector Description
POWER 5-pin Connect the ServSwitch’s power supply cord
DIN F here. This is not a keyboard input. Power
transformers are available for 110 VAC or 230
VAC. Both have center-tapped output of 17 VAC
at 700 mA.
2.5 Cable Requirements
Many switches of this type have what seems like ten million connectors on their
rear panels: one for each CPU’s video cable, one for each keyboard cable, and a
third for each mouse cable. The potential for tangling or mismatching cables is
high.
By contrast, you can connect the ServSwitch to your CPUs with one “CPU Adapter
Cable” for each CPU. This single cable reaches the CPU’s video output, keyboard,
and mouse ports.
Lastly, you can connect the ServSwitch to the shared monitor, keyboard, and
mouse with a single “MKM Adapter Cable.”
The exact variety or varieties of these cables that you’ll need will depend on the
equipment you are connecting for your application. Refer to
Appendix B for the
available types of these cables and the corresponding product codes. Also refer to
Chapter 1
for information about maximum cabling distances.
NOTES
SVGA (over longer distances) and XGA video place special demands on
cabling that the regular MKM Adapter Cables and CPU Adapter Cables
typically cannot meet. For these applications, you should use coaxial
cables that can carry video signals not only farther but also at higher
resolutions. See Appendix B. To carry true monochrome video, or to
share a 9515, 9517, or 9518 monitor, you will need special cabling. Call
Black Box for technical support; we can give you a quote on these types
of cable.
For systems in which some CPUs output EGA video and others output VGA, SVGA,
or XGA, you would need regular VGA-type or coaxial SVGA/XGA-type CPU
Adapter Cables for all CPUs, as well as an EGA-to-VGA adapter for each EGA
computer. Call for a quote on EGA-to-VGA adapters.
