| 9 | There is a serial port for debugging. This port can be accessed via one of the two TIB RJ45 jacks, but only after |
||
| 10 | a small hardware modification has been made. Please reference the following picture for details. |
||

| 12 | After soldering those two connections, the pin-out of ''TIB out'' is as follows: |
||
| 13 | |||
| 14 | * Pin 7: PPC UART Tx (3.3V) |
||
| 15 | * Pin 8: PPC UART Tx (3.3V) |
||
| 16 | * Pin 10: Ground |
||
| 17 | |||
| 18 | You can use any level shifter to get the signal up to true RS323 values, or directly connect something like a FT232. |
||
| 19 | |||
| 20 | There seems to be some kind of serial console on the device, we haven't yet figured out more details. |
