Version B:
The interface module is located at the beginning of the data line; one reading head is
located at the end of the data line. Both need the RS 485 terminator. The second reading
head is connected to the line connection between the interface module and the first
reading head through a short spur (length < 1 m). Use bus terminal BT111 to connect the
spur.
