Table 7.3—Pinouts for ARINC 429 modules
7.3.3 ARINC 708
The pin assignments for ARINC 708 modules are listed in Table 7.4 below. Each
channel can use either of two buses, which are shared between adjacent receive
and transmit channels. Thus, receive channel 0 can listen to either bus, one of
which could have the transmissions from channel 1. Be sure to follow the
