... Everything worked fine whilst the enclosure was open (with the 2 halves sitting beside each other) and was still fine until the two halves were closed to within about 5mm. Once the final closure happened though, there was a problem with the signal transmission between the RX and WD units. I put this down to interference so tried a small shield made out of a piece of aluminium tube. That did the trick and now everything works fine.

You never talked about your intention to have the two units working side by side ...

So, and for everyone which wants to have a Wireless Display unit working very close or side by side with a Pro2 receiver, here is a small and easy trick:

Don't install the RX module in the Wireless Display unit, instead, just connect a single wire from the TX Dat pin of the Pro2 receiver to the RX Dat pin of the Wireless Display unit.
Of course we should have a common GND between the two boards (don't use the GND pin of the TX module for this)
Configure the software normally, setting the same Relay_ID on both units, and that's all.


If there is no intention of Broadcast data to other Wireless Display units, the TX module on the Pro2 receiver can even be removed or not used.
