Cable routing in the RS 485 bus
The data cable must always form an in-line connection between the first and the last node. This
in-line connection must end with a terminator.
The RS 485 terminators are integrated in the WCS reading heads and can be switched on and
off with the interface module.
If only
one reading head
is connected, one device is connected at the beginning and one
device is connected at the end of the data line.
