Configuration and Setup

The CMe3100 M-Bus Metering Gateway can be easily configured and updated through its web interface. Follow these steps to set up the device:

1. Connect the gateway to a power source using the supplied cables.
2. Access the web interface by entering the gateway’s IP address in a web browser.
3. Follow the on-screen instructions to configure the gateway settings, such as integration protocols and meter readings.
4. Save the settings and ensure proper communication with the receiving system.

Data Compilation and Delivery

The CMe3100 gateway reads data from up to 512 meters, compiles it into customized reports, and delivers it to a receiving system. Here’s how to manage data compilation and delivery:

1. Set up the gateway to read data from the desired meters using the M-Bus standard protocol.
2. Create customized reports based on the compiled data for specific analysis requirements.
3. Select the delivery method (e.g., ModBus, DLMS, JSON, REST) for transmitting the reports to the receiving system.
4. Ensure regular updates and maintenance of the gateway for efficient data delivery.

FAQs
