PR55-1A with PR52-3B firmware wiring

Looking for some help wiring this device to an open collector pulse output.
The wiring is as shown:

The included cable for the counter device has 5 wires. Closing the loop between the blue and black wire will increment the counter. +3v on the black wire, which the manual shows this is COM? No voltage across the white and black.

Which wires do i need from the PR55-1A device and how should it be wired to make this work with the meter?

IOs are pulled low internally, and if you connect them to com, it will set the io high, and the counter will increase by one.
