General Sensor Inputs
The TRC can use four general sensor inputs: barometric altimeter, radio altimeter, magnetic heading, and
GPS navigation data. Five receive channels have been designated for these inputs and will allow various
combinations of speed and equipment types. It is also possible for multiple data inputs (barometric
altimeter, radio altimeter, magnetic heading and GPS navigation) from one source to be received on one
channel (e.g., ARINC-429 superbus). Receiver speed and equipment type must be set via the service
menu. When planning the ARINC-429 interface note the following:
NOTES
1.
The data rate for RX channels 1 and 2 must be set to the same speed
(12.5 or 100 kHz).
2.
The data rate for RX channels 3 and 4 must be set to the same speed
(12.5 or 100 kHz).
3.
The data rate for channel 5 is independent of the other receivers.
Channel 5 can be set to 12.5 or 100 kHz.

Mode S Transponder I/O (future option)
The TRC has one receive and one transmit channel designated for the mode S transponder XT & TX bus
interface. The receiver and transmit speed is fixed at 100 kHz. This is a future option, do not connect at
this time.
