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 Micro 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 Micro 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 Micro 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.

We don’t normally recommend using CAT5e cable (rated for up to

155 Mbps), although our EYN795MS cable has performed well in testing. Avoid using cables rated “Level 6,” “Level 7,” etc. If you have problems getting a good picture with CAT5e cable, or if you must use cables with bandwidths higher than 155 Mbps, please contact tech support; the signal-skew problems caused by tightly twisted pairs in these cables can sometimes be resolved by swapping which pairs are used for which signals or by using an external delay line.
