Using a Duet Wifi 1.03 (running 2.02RC1 (RTOS)) with an Integrated Panel Due.

For some reason the Integrated Panel Due keeps saying "connecting". I've updated my Panel Due firmware to 1.21.3, however no luck.

The cables are connected, I've switched between the 4 pin (no breaks in the cable) to the SD ribbon and no luck there. Tried every baud rate on the panel due.

I am able to view temperatures and XYZ co-ordinates via the web interface so I know that those are reading okay.

Have I got a dodgy board? Any body have similar issues, or managed to fix it?

I'm going to TCT tomorrow, so will be sure to discuss it with the guys on stand there.
