Has anybody got the RS485 port on the Atom Switch module to function? I'd like to use it as a Modbus Master and read data from a serially-connected slave, but none of the example code that I've found works when I connect the unit to my existing trunk. (I've got a modbus scanning tool that I use and can see my other devices on the bus, but not the Atom Switch module, with either wiring polarity termination).
