Yep. The default time is 5 minutes and the default UID us the board serial
number.

Currently it is serial but if there is a PC that can act as a bridge then
it
can/will.

I think RBControl is the schema I use but I would have to check the docs
later to be sure.

Ask some specific questions and I'll do my best to answer them. Otherwise
it
is simply a 32k Atmel chip on a serial link to the PC. It has 8 open
collector outputs and 16 static protected inputs to start with. The program
in the micro takes about 12k at the moment.
