RJ-45 CABLES AND ADAPTERS
IMPORTANT
:
The DS-RPC host communications modules have
an RJ-45 port which uses an 8-pin crossed modular cable to
connect to a local EIA-232 device such as a computer terminal or
external modem. Most serial computers do not have RJ-45
connections; therefore an adapter is provided with this unit to
convert from a DE-9 connector to an RJ-45 connector (Bay Tech
Part No. 9FRJ45PC-4). An adapter to convert from a DB-25
connector to an RJ-45 connector is also available from Bay Tech,
upon request (Bay Tech Part No. 25FRJ45PC-4). The 8-pin
crossed modular cable is configured to operate with these adapters.
CAUTION: All power should be removed from the DS-RPC
prior to removing or installing cables.
Figures 1 and 2 provide visual representation of an RJ-45 receptacle and
plug; pin number assignments are given in Tables 2 and 3.

DS73TP CONNECTION
You should connect a straight cable between the RJ-45 ports of the DS73TP
module and the network hub. The “LINK” light will light green when a good
link has been established.
