Tx/Rx pin layout?

I’m trying to connect the CMUCam from the FIRST kit to my vex controller. I know this is possible by connecting the TTL conveter for the camera to the TX/RX, but i don’t know what pin of the three carrys data.

If you compare it to the standard input pin RED is +5, Black is Ground, White is RX/TX. If you are using a CMU CAM plug directly into its TTL port and skip the adapter board.

The easiest way to complete your “MOD” is to kill a pair of bump/limit switches
and use the cable to make an adapter.
