Hi all,

Can anyone tell me what the wiring configuration is to connect an HAI RC-80 thermostat
to ECS?

The owner's manual says to refer to the connection diagram provided by the automation
software, and the ECS manual says to refer to the manufacturer's instructions.  It's
a 4 pin connector with yellow, green, red, and black wires on it.

I'm assuming it's RS-232 and want to hook it up to a DB-9 connector on the PC.

Since I have 3 of them, do I have to dedicate a serial port to each one?  The manual
says they can be connected in parallel, but I didn't think the RS-232 spec supported
this... perhaps it's RS-485?

Thanks,
Brian
