DIP switches:
DIP switch S1 can be used to switch off selected bus lines allowing an additional security feature to function.
This allows the ACS-8 to de-activate selected lines following a trigger event.
With all switches in the OFF position (factory setting) all the RS 485 lines are active. Any lines whose DIP switch
is set to ON can be deactivated by the ACS-8. This prevents any tampering affecting the other data buses from
the communication module.
