Communication programming instructions
Polarization and termination of the RS485 bus
The bus can be polarized from your device if necessary. To
do this you must switch the two micro-switches (Pol. RS+ (A) and
Pol. RS-(B)) of the electronic card in ON position.
If your device is the last on the line on the RS485 bus you
can switch the Term. RS switch on ON to activate line termination.
For security reasons, it’s imperative to turn OFF the
power of your device before opening the case to switch
the micro-switches!
