1.4.4 Setting up the three additional pulse inputs
The optional pulse inputs 1 + 2 + 3 for external meters can be set up using a suitable configuration software. You can configure
serial number, manufacturer, version (0 ... 255), medium code, input pulse value, unit and starting value of the external
meters.

Installation notes for pulse inputs:
It is important that the pulse cables not be affected by (or exposed to) an external voltage!
Check the polarity of pulse generators with "open collector" outputs.
The cable wires must not touch each other during installation, otherwise pulses will be counted in the instrument.
When setting up the meter it may be necessary to adjust the meter reading of the instruments connected and the pulse value
using a suitable configuration software.
For transmitting the values of the pulse inputs via radio, transmission must be set using a suitable configuration software, if
the meters were not already ordered with the transmission of these values set.
