This has been mentioned before (briefly):

Note it does claim to have a voltage output as well as RS485 (maybe that's temperature only though?)

Hi,
Do you have the D or A/E model.

PASSIVE or ACTIVE ?

DID YOU READ THIS ?

YOU linked it so presumably you have it.

Why are you "struggling " ?

What is the problem ? (is it that you can't read or can't understand or both ?)

Did you read the section on interfacing the USB cable with the RS-485 pins on the 8-pin connector ?
