Installation & Operation
Connections
Installation of the ServSwitch CX Remote modules is straightforward and minimal
configuration is required in most cases. Each of the (up to) two moulded SAMs
(
Server Access Modules
) connect directly to a computer system, while the remote
ServSwitch CX Remote module is at the other end of the twisted pair cable run(s)
and attaches to the keyboard, mouse, etc.
ServSwitch CX Remote receiver units can also be used with ServSwitch CX digital
switches to allow one or more user consoles to be placed remotely from the
central unit.

Cable length advice
The ServSwitch CX Remote modules support twisted-pair structured cabling
within categories 5, 5e and 6. Of these three cable types, category 5 generally
provides the best transmission of video signals because its four pairs of
conductors are the most evenly twisted.
Category 5e and 6 cables use conductor pairs that are unevenly twisted in
order to combat interference effects encountered within higher frequency
networks. While these uneven twists work well for Ethernet signals, they
can impose problems for the video signals transceived by the ServSwitch CX
Remote modules. The SAMs send the red, green and blue video signals on
separate twisted pairs within the cable. If any of the colour signals are made to
travel slightly further or shorter distances than the others, the result is seen as
misaligned colours on screen. This is called
skew
and becomes more noticeable
as cable runs become longer and screen resolutions/refresh rates increase.
As an approximate guide, you should expect the following maximum cable
lengths:

When used with an ServSwitch CX switch
It is possible to locate each SAM up to 50 metres from the ServSwitch CX
switch. This distance must be taken into account when planning the cable run
from the ServSwitch CX Remote to the CX switch. The total distance from any
ServSwitch CX Remote to any SAM must not exceed 980 feet (300 metres) or
less if an ServSwitch CX Remote without de-skew is used.
