1.3.2.7 Interface Module - Function
The Interface Module is a frame for accommodation of the NMEA Interface or other optional interfaces.
Installed interfaces are accessible from the rear of the radio.
The Interface Module carries connectors X511 to X534, used for connecting up to three optional
modules to the radio, as well as connectors X11 to X13, which establish the connection to the
Motherboard (see Fig. 1.9).
Via these connectors and lines, signals are exchanged with the RDB (Radio Data Bus), DISC (Discrete)
Bus and RCB (Radio Control Bus), and discrete signals are communicated between the platform and
the optional modules. In addition, the required operating voltages are fed in at these connectors.
