Configuring an eGauge

eGauges require some configuration in order to be ready to connect to Critical Labs.

To configure the eGauge, you will need a power supply and either an ethernet cord to connect the unit to your LAN or a device that has an ethernet port to be able to plug directly into the unit and configure your network settings to be able to reach the eGauge configuration web page.

Connecting to the eGauge from the Internet

To access eGauge from the Internet, plug in the eGauge's power supply and connect an ethernet cord. Then open a compatible web-browser and visit the Web page at: http://egauge.net/devices/

Find the name of your device (e.g., eGauge53 found on the unit) on that page and click on it. This will connect you to your device.

Alternatively, you can directly enter the following Web address into your browser: http://devname.egaug.es/ where devname is the name of your device (e.g., “eGauge53”)

Connecting to the eGauge directly

By default, the eGauge will attempt to obtain an IP address and associated information through a service called Dynamic Host Configuration Protocol (DHCP). If you cannot or do not wish to run this service on your LAN, or there is no LAN or network environment, the device will default to using IP address 192.168.1.88, so the device can be accessed as: http://192.168.1.88/.

Connect a computer to the same network as the eGauge, or directly to the Ethernet port. Then configure an IP address of 192.168.1.11, with a netmask of 255.255.255.0 on your computer. Then navigate to http://192.168.1.88/ in your browser.

Configuring the installation

Once you have opened the eGauge web page in your browser you will need to configure the CTs and the registers that will be recorded.

Navigate to Settings -> Installation

On the installation page, you will need to configure any PTs (Potential Transformers) and the type of CTs (Current Transformers) that will be installed on the unit.

Once you have configured the PTs and CTs, configure the registers that will be recorded. The standard Critical Labs configuration is to record Amperage for each CT, Voltage for L1, L2, and L3, and Frequency for L1, L2, and L3.

Use the screenshots below as a guide to configure the registers. Depending on the model of eGauge, the registers configuration may look a little different. Please refer to the eGauge owners manual if there are any discrepancies.

Here is another example on a different model that only has 15 CTs:

Once you have finished configuring the registers, click Save. You will be prompted for a username and password. The default username and password is: owner/default.

Enable Modbus TCP

From within the Settings page, navigate to Modbus Server.

Select the checkbox labeled Enable Modbus TCP server and click Save.

Configure a static IP address (Optional)

From the Settings page, select Network Settings.

Uncheck the box labeled Automatically obtain address with DHCP. And then enter the static IP address configuration. Be sure to validate all of the settings before saving, once you save the device will reboot with the new settings and you may be unable to reach the device if the settings are incorrect. Once you have validated the settings, click Save. You may be prompted for the username and password, if they have not already be entered. The default username and password is: owner/default.
