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,
avoid
using cables rated CAT5e, “Level 6,” “Level 7,”
etc.
