8.4 MATRIX PORTS – D9
The same connector pin-out applies to ports used for panels or externals. External (4-wire)
connections will not use the data pairs. Cable is quad twisted 100Ω pair, with overall screen.
STP or FTP cables should be used for all installed cables. See Specification for maximum
cable length. We suggest a CAT 5 type cable, from a recognised supplier such as Beldon.
