Figure 7
The wire gauge for the pulse output
cable should be between 16 to
26 AWG to properly fit in the wire
termination connector.
The pulse output ground should
be properly connected to the
customer equipment ground, while
the pulse output signal should be
properly connected to both the
customer equipment pulse input
and an external pull up resistor to
an external supply (if the customer
equipment doesn’t contain the pull
up resistor).
