Tested with the meter which supports pulse output (S0) and 2N SmartCOM PRO ETH with firmware 1.13.x

• S0 pulse inputs (You can increase the S0 bus resistance against interference if necessary by connecting PullUp voltage from the power supply or an internal 3V6 supply)

Disconnect the 2N SmartCom PRO from the power supply before opening the cover. Be careful while handling the jumpers to avoid damaging the device!

Make sure that the 2N® SmartCOM PRO ETH jumpers are set as shown in figure
