P1 is a 50-pin, Champ 0.8 mm receptacle connector. The AMP part
number is 787096-1.
Signal pairs “TXnA”/”TXnB” and “RXnA”/”RXnB” are the positive and
negative lines of an ARINC differential pair.
The discrete inputs and outputs share the same lines. There are a total
of 16 bi-directional discretes on the CEI-820, each of which can be
treated as an input or an output. For example, you may choose to use
discretes 1-4 as inputs and 5-16 as outputs.
Discrete inputs/outputs 9-16 are available only on the mezzanine
connector (P14).
Optional, non-ARINC 429 protocols are assigned to the following
channels for configurations that support them:

ARINC 573/717
Bipolar return-to-zero encoding

ARINC 573/717
Harvard bi-phase encoding

Since they use the same pins,
BPRZ & HBP encoding cannot
be used at the same time.
