1. How to set up the M-Bus interface on Landis+Gyr E350 meter?

To configure the energy meter, please follow the article How to configure Landis+Gyr E350 ali E450 in the MAP120 tool.

2. Physical connection

Please connect M-BUS on the energy meter directly to Reduxi Landis Converter RS485-M-BUS. The first four pins at the energy meter are available for M-BUS. The picture below shows you can use the left's first two pins or the left's 3rd and 4th pins.

From Reduxi Landis Converter RS485 side, please connect to Reduxi Controller or Reduxi Gateway, and choose port one or port two:

A->A

B->B

GND->GND

On the interface, there has appeared a green light and a blinking yellow color. If the yellow color is not blinking, the energy meter is not set from electro-distribution and does not send the data.

3. Get the Serial Number of the energy meter

The serial number can be read from the energy meter. Please take a look at the picture below. The red square shows the last four digits of the serial. Another part of the serial is hidden due to security reasons. In your case, please read the whole serial from the energy meter.
