Installation & Operation

Connections

Installation of the X100 modules is straightforward and minimal configuration requirements in most cases. The moulded CAM (Computer Access Module) connects directly to the system, while the remote X100 module is at the other end of the twisted pair cable and attaches to the keyboard, mouse, etc.

Cable length advice

The X100 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 X100 modules. The X100 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 mis-aligned 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 (achievable at resolutions up to 1600 x 1200 @ 60Hz):

Category 5	Category 5e or 6
100m ¹	50 to 100m ¹

¹ length limited by skew in the cable.
