[Ovmsdev] Relay through diag port.

[Mark Webb-Johnson]

Tricky. It is just a tap into the modem comms.

But, there is an expansion connector on the board itself.

The part labelled "HEADER 9X2" is a standard layout for expansion plugs, or holes are there to directly solder to the board. The I/O is 5v digital on those pins, and there are quite a few spare I/O pins that you can use.

There is also GND, +12V and +5V if you need power.

If you have a use for this, it would be quite simple to control some of these pins on/off on command (similar to the way home link works).

Regards, Mark.
