Figure 12-2. RCU Partitioning of Functional Sections
The control section contains the modules that:
Scan the front panel for operator instructions.
Provide outputs to the display.
Provide the remote control interface to an RT.
Modulate and demodulate baseband signals.
Provide control over the routing of baseband signals.
The control section is described in paragraph 12-2.
The ICOM I/O section contains modules that:
Perform bit synchronization.
Provide enhanced data handling capability.
Route and process baseband signals.
Encrypt and decrypt CT signals.
Interface to the AUD/FILL and AUD/DATA connectors.
The ICOM I/O section is described in paragraph 12-3.
The speaker amplifier section provides the amplification circuitry needed to drive the external speaker. The
speaker amplifier section is described in paragraph 12-4.
The power supply converts the dc input voltage into the voltages required by the other modules in the RCU. It is
described in paragraph 12-5.
