CAT5 Cable Guidelines 
Use only straight-through-pinned four-pair (eight-wire) Category 5 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, etc., 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 CPU to any user station should not exceed 1000 ft. (304 m). 
Please note that although users and servers can be located up to 1000 apart, for optimal video 
quality, limit cable length between the Main Switching Unit and CIM to less than 100 feet (30.5 
m). For good video quality, limit cable length between the Main Switching Unit 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, Pair 2 
2  Orange/White  RX, 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
