DataLogger Mini

This manual explains the hardware setup, Modbus RTU wiring, and internet connection options for the EcoPhi DataLogger Mini.

1. Hardware Setup

1.1 Prerequisite

Before beginning the setup, ensure that the green 6-pin terminal block is plugged into the matching terminal on the device. This makes cable connection easier and helps keep the installation process organized.

1.2 Assembly

The DataLogger Mini comes with:

• 1 external antenna
• 1 green 6-pin screw terminal block
• 1 DIN rail clip
• 1 wall mount

Attach the antenna to the designated antenna connector on the top of the device. Then plug the green terminal block into the power input and RS485 connector on the bottom of the device.

If required, use either the DIN rail clip or the wall mount for installation.

1.3 Power Supply

For stable and reliable operation, follow these power supply recommendations:

Recommended power supply

Use a 24 V / 2 A power supply connected to the + and - power input terminals on the terminal block. This setup is recommended in particular when the device uses GSM communication.

Alternative power supply

The DataLogger Mini can also be powered via USB-C using a 5 V power source. However, this can lead to an unstable GSM connection and should only be used if the recommended 24 V supply is not available.

2. Modbus RTU

Connect your Modbus RTU devices to the RS485 A(+) and B(-) terminals of the terminal block.

For reliable Modbus communication, also connect the ground terminal labeled - on the DataLogger Mini to the ground of your Modbus devices.

Note

Once the devices are connected, the readout configuration can be set up on the EcoPhi Platform.

3. Internet Connection Setup

The DataLogger Mini supports Wi-Fi, Ethernet, and GSM for internet connectivity.

Note

Once a successful network connection has been established, a blue LED on the bottom panel lights up. Depending on the selected connection type and the available network coverage, this can take a few minutes after startup.

3.1 Wi-Fi Connection

1. Press the onboard button labeled KEY to start the configuration interface.
2. Open the Wi-Fi settings on your mobile device.
3. Search for the setup Wi-Fi access point. It appears as Ecophi Setup AP SERIALNUMBER.
4. Connect to this access point using the password EcoPhiSetup.
5. If you are not redirected automatically after a few seconds, open a web browser and go to http://192.168.4.1.
6. Adjust the device configuration as needed in the web interface.

3.2 Ethernet Connection

Connect the device to your LAN using an Ethernet cable and wait for the connection to be established. This usually takes only a few seconds.

3.3 GSM Connection

If GSM is available, allow the device to boot up and connect automatically. This process can take up to 2 minutes.

4. Connection Priority

If one connection type cannot be established, the device automatically tries another one based on the selected connection order.

You can define the connection order either in the local configuration interface or on the EcoPhi Platform.
