Version B:
The interface module is located at the beginning of the data line; one WCS reader is
located at the end of the data line. Both need the RS-485 terminator. The second WCS
reader is connected to the line connection between the interface module and the first
WCS reader through a short spur (length <1 m). Use a bus terminal to connect the spur.
