ConMod User Manual 1.0.3
Overview
ConMod P1Modbus is a small industrial protocol converter for smart Meters with P1 interface output to convert
meter data into industrial standard protocols Modbus RTU and Modbus TCP with interfaces RS485 and Wi-Fi (2,4GHz).
They are designed to convert smart meter data into the most popular industrial protocol – Modbus. The solution
perfectly fits integration with energy management systems, remote monitoring, SCADA systems, etc.
ConMod P1Modbus is compatible with the DSMR interface and supports different versions and variations of data
formats. Also, ConMod P1Modbus has a menu to show RAW data (P1 telegram) collected from the smart meter to
enable comparison with converted data in Modbus registers.
ConMod P1Modbus is designed for industrial applications with cybersecurity in mind to disable Wi-Fi communication
and avoid illegal communication over Wi-Fi in critical infrastructure projects.
Features
Easy configuration using Wi-Fi via mobile phone or a laptop;
Indication about P1 interface, RS485, and Wi-Fi data on built-in LED's;
Both Modbus RTU and Modbus TCP are available at the same time;
Debug information about P1 telegram available with every data frame from Smart Meter;
Support different meters with DSMR interfaces like SAGEMCOM and others;
Easy to change Modbus Slave ID and serial communication speed;
Built-in switchable terminating resistors for RS485;
Possibility to provide power for protocol converter from P1 interface as well from external power supply;
Wide power supply range from 5V to 60VDC;
External Wi-Fi antenna with SMA connector;
Wi-Fi on/off switch;
Reset the device button;
Communication port RS485, Wi-Fi (2,4GHz B/G/N);
Modbus RTU, Modbus TCP protocols.
Connection
It is highly recommended that the RJ12 wire is not longer than 7 meters, otherwise the connection might be
unstable.
To connect ConMod to a meter, an RJ12 cable is required. As shown in the picture below, one side of the cable is
connected to a ConMod P1 port, and the other one to a meter. After connecting P1 LED will light up. Instructions on
how to connect to a Wi-Fi are described below in the paragraph Connection and Configuration over Wi-Fi.

This could be either meter or WCC Lite. By holding a reset button for ~5s, ConMod resets the Wi-Fi connection and allows it to connect to another network instead.
- Page 9 As seen in the image above, there is a message indicating that no AP (access point) is set. This means that the user will have to enter a password. To do so, simply click on Configure Wi-Fi, then select the Wi-Fi you are connecting to and enter the required credentials for this specific access point: After entering the correct credentials click on save.
- Page 10 Another way to connect is via web address conmod.local but only after the connection is established. The user interface also allows to setup of Modbus parameters such as slave ID and baud rate: There is also an option to read all the parameters from the meter without connecting ConMod to WCC Lite. Those parameters could also be found on the user interface by clicking on P1 raw data.
