Terminal Unit, Ic-215 - Nera Inmarsat-c Service Manual

2.3 Terminal unit, IC-215

The terminal unit consists of PWR board (16P0211), RF CON/CPU board (16P0208A) and
TERM CPU board (16P0209).
RF CON/CPU board and TERM CPU board are communicated by RS-232C.
The transmitting control unit such as Nera C 10/11/12 has the function of RF CON/CPU
board, and the terminal unit such as IC-511/IB-581 has the function of TERM CPU board.
Fig.2.3.1 shows the configuration of the terminal unit.
Note) When changing RF CON/CPU board, use EEPROM, U15 which memorizes
the ID (Forward/Retune ID) for communication, the ENID (Fleet Net ID) for
receiving EGC Fleet Net broadcasting, DNID (Data Network ID) for the data
reporting service.
