If
two reading heads
are attached to one interface module, there are two wiring versions:
•
Version A:
One reading head is located at the beginning and one reading head at the end of the data
line. With two reading heads, the RS 485 terminator is activated. The interface module is
located between these two heads and does not have an RS 485 terminator. Each reading
head is connected to the interface module by a separate data cable.
