OUSE
An included User Cable (also called a Monitor/Keyboard/Mouse [“MKM”] Adapter
Cable) connects your monitor, keyboard, and mouse to the ServSwitch Professor.
System Control Module Kits include one PS/2 style User Cable with 6-pin mini-DIN
keyboard and mouse connectors and one PC/AT style User Cable with a 5-pin DIN
mouse connector and a DB9 mouse connector; you can use the cable you need.
The Student Module Kits for PS/2 include just the PS/2 style cable. The Student
Module Kits for PC/AT include just the PC/AT style cable. If you lose this cable or
ever need another one or a longer one, it is also available separately; see
Appendix B
.
CAUTION!
Make
very
sure that the monitor, keyboard, and mouse you plan to use
can meet the demands of your application—see
Section 4.1
. Also, note
that the Professor doesn’t support most keyboard-line dongles.
If you order a longer replacement cable, be careful where and how you
run it; see the other Caution notice below.
Take these steps:
1. After you verify that the Professor is turned OFF, plug the DB25 male
connector of the User Cable into the DB25 female port labeled KEYBOARD/
MONITOR/MOUSE on the ServSwitch Professor’s front panel.
2. Plug the cables from your shared monitor, keyboard, and mouse into the
corresponding connectors on the other ends of the User Cable.
3.3.4 C
ONNECTING THE
CPU
An included CPU Cable runs from the ServSwitch Professor to the keyboard port,
mouse port, and video-output port of the CPU you want to directly attach to it.
System Control Module Kits include a PS/2 style CPU Cable with 6-pin mini-DIN
keyboard and mouse connectors, plus PC/AT keyboard (5-pin DIN) and mouse
(DB9) adapters. Student Module Kits for PS/2 include a PS/2 style CPU Cable but
not adapters. Student Module Kits for PC/AT include a dedicated PC/AT style
CPU Cable. If you lose this cable or an adapter, or ever need another one or a
longer one, they are also available separately; see
Appendix B
.
CAUTION!
Avoid routing longer replacement CPU or User Cables near fluorescent
lights, air-conditioning compressors, or machines that may create
electrical noise. Total length of original Serv cable (not including bus
cable) from any keyboard, monitor, and mouse to any given CPU should
not exceed 15 ft. (4.6 m). For typical equipment and video resolutions,
length of coaxial cable should not exceed 20 ft. (6.1 m) from a Professor
to any attached device (keyboard, monitor, mouse, or CPU). However,
we do provide coaxial cable in lengths up to 100 ft. (30.5 m), because
some CPUs can drive and receive keyboard and mouse signals at
greater distances than others. See
Appendix B
.
