Looking at the BCM signal today it is def serial RS485, and looking at the BCM board I have found the two transceiver chips are Linear Tech 1487.

Datasheet below.

Now just got to capture and analyse it.

I'll order one of these chips so I can drive it with a picaxe and send some data on the rs485 bus.

Another useful device I've just ordered to play around with is.
