Cat5 Cable Guidelines
Use only straight-through-pinned four-pair (eight-wire) Cat5 unshielded
twisted pair (UTP) cables, terminated with standard RJ45 plugs, for the
Cat5 cabling links in your Paragon system.
If your existing Cat5 site-wiring system meets these requirements, feel
free to send the signals through your site's patch panels, existing wiring,
and so on, but you should keep the number of patches and splices to a
minimum to avoid degrading the video signals. Maximum end-to-end
cabling distance from any server to any user station should not exceed
1000 feet (304 m).
Please note that although users and servers can be located up to 1000
feet apart, for optimal video quality, limit cable length between the user
station and CIM to less than 100 feet (30.5 m). For good video quality,
limit cable length between the user station and CIM to less than 500 feet
(152 m).
Looking into an RJ45 socket on any Paragon component, or looking at
the cable plug from behind with the tab on the bottom, Pin 1 should be
on the left and Pin 8 on the right, and the wires should be arranged this
way, as per the TIA-568B standard:
Pin Color Function Pair
1 White/Orange TX (transmit signals) Pair 2
2 Orange/White RX (receive signals) Pair 2
3 White/Green TX Pair 3
4 Blue/White RX Pair 1
5 White/Blue TX Pair 1
6 Green/White RX Pair 3
7 White/Brown TX Pair 4
8 Brown/White RX Pair 4
