Ok, I just purchased two TR-40 thermostats for upstairs and downstairs, a two port RS485 card for the HS pc. I have a few questions.
Can I use Cat 5 cable to connect to the RJ45 jack in the TR-40 control unit to the RS485 card in the HS pc?
What else do I need to install other than the HS plugin?
The serial thing is new to me. In the past I have only used X-10.
Thanks in advance
