3.2 Interconnection Cable Requirements
To connect the Local and Remote Units you will need CATx (any category 5, 5e, 6 or higher)
cable terminated with RJ45 plugs. Please note that shielded cable is advised to maintain
regulatory EMC compliance.
Interconnect cables must be solid-core type. Stranded patch cable will give poor results over
longer distances. The pairing of the cable and pinning of its connectors should normally be in
accordance with EIA-568B (see page 49).
One CATx cable is required for each video channel.
•
The Primary interconnect cable connects INTERCONNECT Port 1 on the Local and
Remote Units. This carries the main video channel and all data (plus audio/serial).
•
The Secondary CATx cable (connected to INTERCONNECT Port 2) carries the
additional video channel on dual-head units.
In order to send USB, Audio and Serial signals to the PC, the Primary
interconnect must be connected.
The Primary interconnect does not have to be connected in order to use the
keyboard attached to the Remote Unit for video setup.
With some cables, video performance may be improved by using a crossover
patch cable at each end or an alternative RJ45 pin-out (see Appendix D:
Advanced Cabling Issues (Skew), page 48).
