Hello,
I just connected my LM5 to my ventilation system (Villavent VTR300). Ive been connected to the modbus for a long time with two different KNX Modbus gateways (weinzierl and MDT) and it have been working perfectly. I now wanted to test the LM5 instead. But after a few seconds I get a error "operaation timed out". I have connected GND, and I have disconnected the other gateways.
I get values right after I change the RTU settings between half and full duplex. Then the erros pops after 20 seconds.
What could be wrong here? The Baud rate is correct (9600).
