The pulse output is open-
collector, that is, a transistor switch to the meter’s
negative supply. To use it, connect it to the input of the receiving device; also
connect that input through a 10K Ohm resistor to a suitable positive supply and
connect the negative supply of the receiving device to the negative supply of the
meter. If an isolated relay contact is required, install the CDI 5200-IPO isolated
pulse output and wire it to the receiving device.

PTION
The RS-485 signal used with the Serial Communication option is wired to the
Serial Communication display board. The two threaded openings in the meter
enclosure permit the signal to be wired from meter to meter without external
splices. Please refer to the data sheet for the Serial Communication options.
