Setting the DIP switches
You can use the DIP switches on the front to set the behavior of the outputs in the event of
an error (e.g., interruption of the wireless connection). Any changes in the setting of the DIP
switches will be directly applied.
–
RESET = Output value is set to 0
–
HOLD = Hold last valid output value
