This FAQ describes how to set 2N® SmartCOM PRO ETH for AMS function. 2N® SmartCOM PRO can with this function automatically read data from the INPUTS and store data in the internal memory. This feature is available for all units with firmware 1.13.X

 

2N® SmartCOM PRO ETH is equipped with three inputs (IN1, IN2, IN3)

Input Interfaces:

 

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 the following image
