Thanks for that. I was looking at the diagram on page 12 to do with
getting the status, (The second row of the split diagram showed
Second Start.

I can always try the different combinations to try and get it working
correctly. From what i see the address is 7 bit with an 8th bit to
say weather the command is being sent to the board or requesting
information from the board. I wasn't really sure how that translated
into mode etc.

Unfortunatly, before I can test this out, I need to get a special 5
pin connector for the OOBoard otherwise I will need to resort to
soldering wires to the connector pins as they are too small for the
jumper cables I already have.

(I've also got a BasicX Developer station board which I can have a go
on (Which is what I'm planning to put the screen on for the Alarm
system I'm working on too).

Thanks for the help.
