Comtrol VS2000 V.34 - Manual (Page 2)

Note: If using an AUI connection to the server, you can
determine proper polarity by using an AUI to
10Base-T converter box.
Modem Cables
The VS2000 modem ports use standard telephone-type
unshielded twisted-pair cables with RJ11 modular
connectors. These cables can be purchased anywhere
commercial or consumer telephone products are sold.
If you choose to build your own cables, use the following
information:
The connector pinouts are as shown below:
When building cables, use Category 3 (or better)
unshielded wiring.
Ethernet Crossover Cable
If you are connecting from the VS2000 10Base-T
connector directly to the NIC card in the server, you
need a crossover cable, wired as follows:
Remote Connector
The DB9 port labeled “Remote” is reserved for Comtrol
Corporation repair and maintenance use. No user-
accessible signals are present on this port.
