Installation & Operation
Connections
Installation of the X200 modules is straightforward and minimal configuration 
requirements in most cases. Each of the (up to) two moulded CAMs (Computer 
Access Modules
) connect directly to a computer system, while the remote X200 
module is at the other end of the twisted pair cable runs and attaches to the 
keyboard, mouse, etc.
X200 receiver units can also be used with AdderView CATx switches to allow one 
or more user consoles to be placed remotely from the central unit.

Cable length advice
The X200 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 X200 modules. The X200 
modules 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:
Resolution 
X00 without de-skew 
X00 with de-skew 
1920 x 1200  
50m 
50m
1600 x 1200 
100m 
200m
1280 x 1024 
300m
 
When used with an AdderView CATx switch
It is possible to locate each CAM up to 50 metres from the AdderView CATx 
switch. This distance must be taken into account when planning the cable run 
from the X200 to the CATx switch. The total distance from any X200 to any 
CAM must not exceed 300 metres (or less if an X200 without de-skew is used).
