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 4.2.5for 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.
