2.22 SYSTEM CONFIGURATION MODULE
The system configuration module (Figure 2-8) is used to store aircraft installation dependent information
(e.g., aircraft type, discrete inputs, heading source, speed of data bus, etc.). Aircraft specific information is
selected via the service menu, typically during system setup. Once the setup settings have been saved the
system configuration will stay with the aircraft wiring allowing the TRC to be replaced or exchanged
without having to re-configure the TRC. When powered up the configuration information is sent to the
TRC via the bi-directional serial data bus (SDA).
NOTE
The system configuration module must be located inside the backshell of
connector P1 and wire-tied to the bundle of wires. Reference Figure 2-9.
