On the TE0791 board are footprints available for 10-pin JST Wire-To-Board IDC connectors J4 and J5 with two different pin-assignments, where all XMOD signals A - H are available. The pin- and signal-assignment with standard System Controller CPLD firmware of the XMOD board are as follows:
| Pin Name | J4 Pin Number | J5 Pin Number | Signal | Note |
|---|---|---|---|---|
| A | 1 | 10 | UART TXD | |
