This is EXTREMELY IMPORTANT as the Interface pins operate at different voltage levels
depending upon the Interface type selected. SERIOUS DAMAGE may occur, for example, if
the External Interface is operating at V.35 voltage levels and the Universal Interface is
configured for RS422 voltage levels.
2.4.1 Modem Connections
All modem connections are made to labeled connectors located on the rear of the unit: The
connector definitions and pinout tables are shown below, and are those on the RCS10 unit and
Universal Interface Modules. Any connection interfacing to the modem must be the appropriate
mating connector. Refer to Figures 2-2 and 2-3 to locate the rear panel connectors.
2.4.2 Connector Pinout Tables
The following paragraphs and tables contain the pinout information for the various data/IF connectors
located on the rear panel of the RCS10.
2.4.3 Universal Interface Module (UIM) Connectors
The RCS10 chassis is shipped with the Universal Interface Modules installed. The following table
lists the signals, descriptions and directions for the connectors located on the UIM. Refer to Figure
2-2 for the three possible UIM configurations.
