A.2.3 RS-422 Input BUS
The RS-422 Bus receives data at 9600 baud on a custom CSDB data format. It may be configured to
operate with an MAG-3000 or MAG-3100 Magnetometer.
A.2.3.1 RS-422 Input Labels
The following labels are inputs from a magnetometer:
•
Label 0A - Magnetometer data
•
Label 0C - Magnetometer fault data

A.2.4.1 Configuration Notes
1.
When Heading Input is configured for ARINC 429, the ARINC 429 BUS #3 and #4 receive data at
high (100 kbps) speed.
2.
When VOR/ILS#1, VOR/ILS#2, TACAN#1, and TACAN#2 are configured for ARINC 429, the
ARINC BUS (see Table A-1 for options) receive data at low (12.0 to 14.5 kbps) speed.
3.
When FMS/GPS#1 is configured for ARINC 429, the ARINC BUS (see Table A-1 for options) can
be configured to receive data at high (100 kbps) or low (12.0 to 14.5 kbps) speed.
4.
When FMS/GPS#2 is configured for ARINC 429, the ARINC BUS (see Table A-1 for options) can
be configured to receive data at high (100 kbps) or low (12.0 to 14.5 kbps) speed.
5.
When VOR/ILS#1 and VOR/ILS#2 is configured for CSDB Input BUS #1, the CSDB can be
configured to receive data at low (12.5 kbps) speed.
6.
CSDB Input BUS #2 is configured for the DME functions if VOR/ILS is configured to use the
CSDB BUS.
