3.4.8 Shield Termination Considerations
For G5 installations utilizing the RS-232, CAN bus and ARINC 429 interfaces, terminate the
shield to the G5, GMU 11 and GAD 29/29B connector backshells as shown in Figure 4-42 and
Figure 4-43. For shield terminations at the GPS or VHF Navigator follow the appropriate
installation techniques as indicated by the manufacturers installation instructions for that unit. If
there are any interposing connectors then the shields must have continuity through the
interposing connector. This can be achieved by
1) Terminating the shields to the backshell of the connector if both mating connectors and
both backshells are metal.
2) Terminating the shield to aircraft ground directly
3) Passing the shield through pins in the connector. This is the least preferred method.
3.4.9 Audio Interference
This STC installation does not interface to audio signals. Attention to harness installation and
routing as specified in Section 3.4.5 should be considered for Audio interference mitigation.
