PC connection Weinmann SOMNObalance fails

[HoogendoornJH]

I downloaded and installed WEINMANNsupport, however, I have problems with the communication between the Weinmann SOMNObalance and my laptop. I wanted to buy the Weinmann converter cable USB-RS485, but couldn't find it anywhere on the internet.

I tried it with a Davis A.T. adapter, which looks similar, but that didn't work.

Does anybody know how to get a Weinmann converter cable USB-RS485 or how to to connect the Weinmann SOMNObalance on an alternative way to a laptop?

I hope I did not misunderstand you.  If you know the Weinmann's pinouts, have you thought about something like this, I found it on Amazon? Of course, you will need to know the protocols to communicate.

Yes, I found similar devices, but I don't know the Weinmann pinouts.

I am now thinking about a combination of an USB to RS485 adapter (amazon.nl/dp/B07SK1D163/?coliid=I1F3X1C2KWH8UE&colid=3OIXGSWS7R8II&psc=1&ref_=lv_ov_lig_dp_it) in combination with a RJ12 to RJ45 cable (onlinekabelshop.nl/rj12-rj45-kabel-3-meter) (the SOMNObalance has a RJ12 port).

The problem is not on Weinmann pinouts.

The problem is on spezial "Konverterkabel USBRS485" WM 93321.
