I have three RCS RS-485 thermostats working for years through a RCS COM Star Hub controlled by my ELK M1 Gold. Now I am trying to move them to work directly with HS3.
I am using a USB to RS-485 adapter model number USA-482422 from gearmo.com. This works fine communicating with the RCS program on the same PC but will not receive one response in HS3 RCS plugin. Same com port is used for both.
I have eliminated the Star Hub from the equation as it would not work at all through that.
Why could this be failing?
