As I remember, the Rain8 only needs 3 wires for its RS232 connection: RxD, TxD, and Ground. Those are pins 2, 3, and 5 on the DB9 connector.

Thanks JKish,

also thanks for the killer driver for the squeezebox and i saw that you created one for the rain 8 too. appreciate your contributions. excellent work.

Thanks, glad you like it.

Once you get the Rain8 installed, you will need to install the Rain8 driver (which I didn't write) and the Irrigation Scheduler driver if you are interested in my stuff. I should have an updated version of the Irrigation Scheduler coming soon.

I have the thermostats now and i think i have them wired correctly except im not sure what the A+ A- B+ B- relationship should be? should i be wiring the TX to A+ and the RX to B- or B+?

Thermostats?

sorry jkish im confusing myself...

im installing the thermostats not the rain8 Sad

The thermostats are RS485 and....welll i need to go back to the drawing board.
