APPENDIX A: Cable Pinning/Pairing

Appendix A:

Cable Pinning/Pairing

The cable you will use to interconnect the Local and Remote Units of your

ServSwitch™ Brand CAT5 KVM Extender should be terminated with RJ-45 plugs

and should be wired according to the EIA/TIA-568 standard (preferably 568B

rather than 568A). See Section 4.2.5 for a more complete set of cable

recommendations.

Looking into the interconnect socket on either Extender Unit, or looking at the

cable plug from behind, Pin 1 should be on the left and Pin 8 on the right, and the

wires should be arranged this way:

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

NOTES

The Extender has been tested with all major makes of CAT5 cable

including Black Box, Berk-Tek

™

, Mohawk

, and AT&T

. The Extender has

also been tested and found to work, in certain situations, with 4-pair

Category 3 cable or with four pairs of 25-pair UTP trunk cables instead

of 4-pair Category 5 cable. But we do not recommend such installations;

if you want to experiment with them, do so at your own risk.

You might be able to use some makes of CAT5e cable (rated for

155 Mbps) between Extender Units at distances up to 120 m (400 ft.). In

general, however, a

void using cables rated CAT5e, “Level 6,” “Level 7,”

etc.
