This section covers the power input requirements. AIRCRAFT POWER 1 and AIRCRAFT POWER 2 are
“diode ORed” to provide power redundancy.
25.2.4 ARINC 429 RX/TX
The ARINC 429 outputs conform to ARINC 429 electrical specifications when loaded with up to 5
standard ARINC 429 receivers. Each ARINC 429 Transmitter pin is physically connected to two DSUB
pins. When running one transmitter to two receivers use two separate pins to avoid splicing wires.
Running one transmitter to more than two receivers will require splicing wires.
