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:
-
Voltage range: 0–10 V DC
-
Current range: 0–20 mA DC
-
Digital input with threshold level setting
-
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 the following image
