Category 5, 5e, or 6
cable.
Fibreoptic versions
available for duplex
multimode or duplex
single-mode.
Access video
equipment locally and

uppose you have a PS/2 CPU
at one location, but need dual
access to it (from either a local or
a remote PS/2 keyboard, DVI
monitor, and PS/2 mouse). The
ServSwitch™ DVI/VGA PS/2 CATx
(twisted-pair), Multimode (fibre),
or Single-Mode (fibre) Extenders
are ideal for any KVM application
that demands flexible video
connections and exceptional
video quality. With these
extenders, you get video
resolution at the local console of
up to 1600 x 1200 for VGA or 1280 x
1024 for DVI.
A PS/2 console is defined as a
PS/2 keyboard/video/mouse
combination. When the keyboard
and mouse are being used at one
PS/2 console, the extender blocks
access at the other console until
there is no keyboard or mouse

activity for a defined timeout
period.
CATx twisted-pair cable is
defined as either CAT5, CAT5e, or
CAT6. Extend the distance from
your PC up to 300 ft. (91.4 m) using
CATx cable and a CATx extender.
For greater distances between
consoles and the CPU, choose the
fibre optic extender models.
There’s one for multimode and
another for single-mode cable.
The multimode model lets you run
62.5/125-µm cable up to 650 ft.
(198.1 m) between local and
remote units, or connect 50/
125-µm cable up to 1300 ft.
(396.2 m). And by using fibre
cable, you get all its benefits,
including immunity to electrical
interference.
The single-mode version
enables 9/125-µm connections up
to 6.25 mi. (10.1 km) apart.
All models include a local unit
(transmitter) and a remote unit
(receiver). Connect the local unit
to the computer’s CPU or server
directly with the included PS/2
cable, and attach the KVM
console to the remote unit.
DVI and VGA adapters are
also included.
The extenders work best with
DVI (Digital Visual Interface) video
displays. However, they also work
with VGA displays, too, with an
adapter cable.
Diagnostic LEDs on both local
and remote units tell you link
status, when the devices are
ready, and when the units detect
a video signal or valid mode.
There’s also an LED to indicate
communication errors.
