Correct RS232 Interface Settings for Drexel & Weiss Aerosmart
OpenDear Loxone Support Team,
I am currently trying to re-establish communication between my Loxone system and a Drexel & Weiss Aerosmart unit via the RS232 interface.
The communication was previously working without any issues. However, after reinstalling/replacing the RS232 adapter, the connection is no longer functioning correctly. I am now only receiving unreadable or junk data from the Aerosmart controller.
Could you please advise what the correct RS232 communication settings should be (baud rate, parity, data bits, stop bits, flow control, etc.) to ensure proper communication with the Drexel & Weiss Aerosmart?
Additionally, are there any specific configuration steps required in Loxone after reinstalling the adapter that I should be aware of?
Thank you in advance for your support.
Best regards, Walter
