INSTALLATION

3.2Interconnection 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.

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 below).

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 USB data.

•The Secondary interconnect cable connects to INTERCONNECT Port 2 on the Local and Remote units. This carries the additional video channel on dual-head units and/or audio/serial data.

Technical Note: Although suitable for use with UTP cable, it is recommended that shielded STP/FTP cable is used with this product if possible, especially in electrically noisy environments. When shielded cable is used, it is most important to ensure that shield connectivity is maintained between the Extender units.

Cable Pinning/Pairing

The following table illustrates which RJ45 connector pins the extenders use for various signals. It also details the standard EIA-568B wiring scheme that is recommended for most installations.

Looking into the RJ45 socket on a Remote unit, Pin 1 is on the right and Pin 8 on the left.

Pin	Color (EIA-568B)	Signal
1	White/Orange	Blue Video
2	Orange/White
3	White/Green	Green Video
6	Green/White
4	Blue/White	Red Video
5	White/Blue
7	White/Brown	Data
8	Brown/White

EIA-568A wiring can also be used. Contact Technical Support for details.
