NOTE
It’s possible to attach an original (non-R2 model) ServSwitch Duo
Extender to the local user-port connectors of an -R2 model Duo or a
Quadro. But we don’t recommend this because the original Extender
can’t make use of the -R2 Duo’s or Quadro’s RJ-45 remote user port.
The -R2 Extender can’t be used with the original Duo.
Attach all of your local equipment to the ServSwitch Duo/Quadro as described in
Section 3.4.1 . Leave everything powered off, and make sure the ServSwitch Duo
Extender and your remote monitor are powered off as well.
Run twisted-pair cabling from the RJ-45 jack in the Duo’s user port #1 or the
Quadro’s user port #1 or #3 to the matching jack on a ServSwitch Duo Extender.
(Do
not attach these jacks to a LAN; you could damage the Duo/Quadro or
Extender and possibly the network as well.) Category 5 twisted pair will give the
best results, but you should be able to use Category 3, 4, or 5e if you keep the
distance short (not more than 100 m [325 ft.]).
Avoid using cabling rated as
“Level 6,” “Level 7,” etc., for data rates above 155 Mbps; the large differences
between the twist ratios of the wire pairs in these cables cause the video signals
from the Duo’s/Quadro’s CPUs to get out of sync with each other.
The twisted pair can be a single continuous length of cable if that’s the best
option. But this kind of cable is often already installed in buildings and terminated
at data-wiring sockets in various locations. If twisted-pair cable is preinstalled at
your site, you can run patch cables from the Duo/Quadro and Duo Extender to
these sockets and set up a direct one-to-one connection between them using the
patch panels in your wiring closets, which will probably be much more convenient.
CAUTION!
Even though the cabling and connectors might be the same, do not
connect a ServSwitch Duo, Quadro, or Duo Extender to your LAN or to
the telephone network. Doing so will damage the device and might
damage the network as well.
Connect your remote user equipment (keyboard, PS/2 mouse, and monitor) to
the appropriate user-port (“control-port”) connectors on the Duo Extender. If you
have had to place the Extender farther from the user equipment than the
equipment’s native cables will reach—up to an additional distance of 30 ft. (9 m)—
you can plug the native cables into Premium KVM User Cable. We don’t
recommend keeping your user equipment any farther than that from the
Extender. If you’re attaching a CPU to the Extender model that supports a CPU
(KV6EXT-R2), follow the directions in your Extender manual.
