A
Cables and Connectors
This appendix lists cables that have been tested and verified for use with the
HP Hub-16M. The following topics are covered:
■ recommended Cables
■ twisted Pair Cable/Connector Pinouts
■ RS-232 Connector and Cable Pinouts
It also includes minimum pin-out information so, if you wish to use an unlisted
cable, you can verify that the cables used in your installation are correctly
wired. Note that each pin-out does not necessarily match the pin-out for the
corresponding HP cable, but cables manufactured to follow the minimum pin-
out will function correctly.
