All the info it's on the board diagram
Perfect, thanks.
Might not be able to have a bash at this for a couple of days but will update with anything I manage to do.

I had a little success with this today.
I used the J22 connectors to connect a 232 cable to my processor (Crestron)
I had to edit Configuration.h slightly
#define SERIAL_PORT 2 \\was #define SERIAL_PORT 0
and
#define BAUDRATE 115200 \\was #define BAUDRATE 250000
I only had to change the baud rate as my processor doesn't support 250000
When I power up the board I get a reasuring barrage of start up data...

echo:SD card ok
This tells me that I am definitely connected, the tx and rx are the right way round and the baud rates match on both devices.
Once this happens I then get
echo:Unknown command: ""
every few seconds. It seems like it is monitoring for commands and if it gets nothing then it gets upset. I'm not too bothered about that yet, what I really need to work out is why it doesn't respond when I do send commands.
I'm also not sure yet what commands I can send to get information I need or to control the printer. (have tried some G and M codes but none of them seem to work)
I think I may have to enable serial 2 to accept and handle control commands somehow...
But serial communication is a good start.

Certainly will.
Serial 3 looks like my ticket, 2, 3 + 4 is all that's needed.
Can you post the full image for me, can't seem to find it...
