For external wrap, connect each transmit signal to the corresponding
receive signal (e.g. TX1+ to RX1+, TX1- to RX1-, etc.).
Also available are the CEI-520-1208-C/CEI-520A-1208-C (which provide
CSDB support) and the CEI-520-xxxx-J/CEI-520A-xxxx-J (which provide
ARINC 573/717 support). The P2 connector pinouts for these
configurations are shown in the following tables.
