Meaning of switches
The WCS-DG310 interface module has 6 switches with the following
functions:
Rx 422/Tx 422 Termination (serial interface)
If the interface module is operated as the first or last physical device in an RS485 bus, there
must be a bus termination on this gateway. To do this, set the slide switch "Rx 422 Termination"
to "Off" and the slide switch "Tx 422 Termination" to "On". This activates the RS 485 terminator
(150
Ω
) built into the interface module.
If you connect only one WCS reader to the WCS-DG310, you must always activate the RS 485
terminator.
