S107USB:
the electrical connections of the S107USB are shown below:
By inserting an external jumper between terminals T1 and T2, the terminator of the RS485 line is enabled.
We also recommend to use a shielded cable for the RS485 line, in particular if long connections are to be made or
in noisy environments.

Terminal connections:
The module has spring-loaded terminals as electrical con-
nections.
To make the connections refer to the following instructions:
1 - Strip the cables by 0.8mm
2 - Insert a flat-blade screwdriver into the square hole and
press it until the locking spring of the cable
opens.
3 - Insert the cable into the round hole
4 - Remove the screwdriver and check that the cable is
firmly fixed in the terminal
