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 52).
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).
• Secondary CATx cables (connected to INTERCONNECT Ports 2 - 4) carry
additional video channels on multi-head units.
In order to send Keyboard, Mouse, 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 set-up. However, if the Primary interconnect is
disconnected, the keyboard cannot be used for configuration for 15 seconds after
disconnection (to maintain data integrity).
With some cables, video performance may be improved by using a cross-over patch
cable at each end or an alternative RJ45 pin-out (see Appendix D: Advanced Cabling
Issues (Skew), page 51).
