eGauge offers limited support for the Multitech cellular modem. This hardware is typically used in locations where local Internet access is not available or secured. The Multitech can accept a variety of SIM cards from various providers. However, eGauge only offers support for T-Mobile data plans purchased through eGauge. If a third party data plan is used, it may be necessary to contact the cellular service provider to obtain the correct information for modem configuration.

Initial Configuration for T-Mobile data plans from eGauge Systems

Typically, Multitech cell modems should work out of the box with the eGauge. However, in instances where the modem configuration may have been changed/cleared, the modem may need to be reconfigured. In order to do so:

1. Connect a computer to the modem using an Ethernet cable. Disable any wireless adapters (WiFi, Bluetooth, etc). Open the web browser of your choice and navigate to (assuming the modem still has the default configuration in place). The default login credentials are admin:admin.

2. The Network Setup Wizard should load automatically. If it does not, select Wizard and then Network Setup Wizard from the menu on the left side of the screen.

3. Set your user credentials and time zone as desired. On the “WAN Interface” page (step 4), choose “Manual-configuration”. Select “USA” as the Country, and “T-Mobile (LTE)”. The following settings will be auto-populated:

APN: fast.t-mobile.com

Dialed Number: *99***1#

These values will not work with other cellular providers. If using a different cell plan, it will be necessary to contact the cellular service provider to get the information needed to properly configure this page. eGauge Systems cannot assist with this process, even if the Multitech cellular modem was purchased directly through eGauge.

4. Apply the settings on the final page, after verifying that they are correct.

Verifying Connectivity

Once the modem is properly configured, it’s time to verify that the installation location and antenna position are viable. The Network Status page is useful for this process. This page can be found by selecting Status and then Network Status from the menu on the left side. Cellular connectivity and signal strength can be verified under the “3G/4G Modem Status”. Ensure that the Link Status is “Connected” and the Signal Strength is reasonable. Anything lower than about 50 percent may lead to communication issues.

If working with an external antenna, it’s possible to use this page to locate the best antenna positioning. To do this:

1. Move the antenna to the desired location

2. reload the Network Status page (F5 key in most browsers)

3. make a note of the Signal Strength

4. move the antenna to the next test location and repeat

Connecting Multiple eGauges

The Multitech is set up to handle one eGauge by default. However, it is possible to connect multiple eGauge meters to a single Multitech cell modem using a powered switch. Some additional configuration changes will need to be made. Navigate to Basic Network then WAN. Near the bottom of the page, make sure “NAT” is checked.

NAT option (shown checked)

Once NAT has been enabled, you can check to see whether devices are obtaining DHCP leases by navigating to Basic Network and then Client / Server. Select “DHCP Server” from the list of options at the top. Next, select “DHCP Client List”. A list of devices with active DHCP leases should be shown. Note that this assumes the computer is connected to the switch alongside the eGauges.

Changing the default credentials

It is highly recommended to change the default credentials on the Multitech hardware for security purposes. Navigate to System and then System Related. Select “Change Password” at the top of the page. Enter the old password (admin) and your new password twice.
