The hardware must be RS-485 compatible.
The line must be made up of a twisted cable with a characteristic impedance
of about 120 W. On the power supply board of the instruments of the "Q" series, there are three jumpers, S1, S2 and S3, with 2 positions that have the
following functions:
Jumper S1 S2 S3
Function of pos. 1 None None None
Function of pos. 2 120 ½ termination Polarization 1 Polarization 1
The standard positions of the switches are indicated in grey.
The S1 pos. 2 termination function is strongly recommended for the two devices located at the two ends of the line, as shown in the following basic diagram:
