Transmitter and reciever error

[Edwin]

I have a error in hs2 transmitter didnt respond with a correct ack
the reciever program cant give any readings either.
Reciever gives when i klick on get reciever version : f020
5A
transmitter program gives respond

cant recieve rfxsensor data or any other data


What to do?

Thanks, edwin

I suppose you have changed COM ports? If you receive 5A on a get receiver version you are probably connected to the transmitter.

I did change comports after the error,com7 for reciever and 8 for the transmitter cant use another any more cause they dont show up annymore. It was first 2 and 3
must i change 7 and 8 around?
Thanks edwin
