Cables and Adapters
10Base-T (Twisted-Pair) Cable
An IEEE 802.3 standard 10BaseT connector is provided for CAT5 (unshielded outer
covering) twisted-pair wiring that is terminated in an RJ-45 modular connector. The
maximum distance between the unit and the network hub using twisted-pair cable is 100
meters (328 feet).
Terminal Cables and Adapters
The RS-232 and Current Loop ports on an AWAN access server are female RJ-45
connectors. Devices such as terminals, personal computers (PCs), printers, and modems
are connected to an AWAN access server using straight-through RJ-45 terminal cables
with either DB-9 or DB-25 adapter hoods.
The AWAN access server adapter hood pinouts are nonstandard, requiring custom cable
hoods to be constructed or purchased from Compaq. Adapter hood pinouts are described
in Appendix C, Adapter Hood Pinouts
.
Table 2-3
describes the adapters that are available from Compaq.
Figure 2-1. Possible AUI Transceiver Configurations
Note. If you want to connect the AWAN access server directly to the Compaq NonStop server
without using a hub, you must use a patch cable instead of the standard 10BaseT cable.
