Multitech Cell Modem Setup (MTE-LAT6-B07)

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.

This document is to be used with the Multitech MTE-LAT2-B07 and MTE-LAT6-B07.

Model Default username / password Notes
MTE-LAT2-B07 admin / admin  
MTE-LAT6-B07 (newer, sold starting around May 2019) admin / admin123 eGauge configures the password as admin123 before shipping. Factory resetting will cause the default password to be admin, and upon first setup a new password is required to be set.
MTE-LAT6-B07 (newer firmware, mid 2020) admin / Admin123 Note password has Admin123 capitalized per password requirement from Multitech firmware. Factory resetting will cause the default password to be admin, and upon first setup a new password is required to be set.

SIM card installation:

To remove the SIM card, push in on the SIM card and it will spring it out from the locked position.

Ensure the SIM card notch lines up with the notch on the SIM card slot image (circled in green below). The modem uses a full sized SIM card, do not remove outer plastic holders of it. When correctly inserted, pushing the SIM card in (may need to use a fingernail) will lock it in place.

A rapid flashing SIM LED indicates there is a problem physically reading the SIM card.


Initial Configuration for T-Mobile data plans from eGauge Systems:

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 192.168.2.1 (assuming the modem still has the default configuration in place). The default username is "admin" and password is either "admin", "admin123", or "Admin123". If credentials have been changed, a factory reset may be performed to regain access with username "admin" and password "admin".

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

Network Setup Wizard - first page

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 must be configured:

APN (this must be changed from default): iot.tmowholesale

Dialed Number (this should remain default): *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.

WAN interface page - page 4

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. 

Network Status page

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. 

Change Password page

 

Factory Reset

To perform a factory reset, power the modem on and allow it to fully boot (2-3 minutes). While the modem is powered up, using a paperclip or other object press and hold in the "Reset" button located on the side of the multitech next to the Ethernet port for 10 to 30 seconds. Release and the Power LED should rapidly blink indicating a factory reset is occurring.

TP-Link powered USB WiFi Bridge Setup (TL-WR802n)

 

Tips for Troubleshooting:

Setup instructions

Do not connect Ethernet to the TP-Link bridge before the setup via WiFi is complete. If an eGauge meter or other device is connected via Ethernet to the TP-Link bridge, the initial setup will not work.

2) Using a laptop with WiFi, connect to the wireless network broadcasted by the TP-Link bridge. The SSID and password are located on a card that comes with the wireless bridge. This information is also printed on the bottom of the bridge itself.

3) When connected to the wireless bridge's network, open a web browser to http://tplinkwifi.net/. Log in using the default login printed on the card that comes with the wireless bridge.


4) Choose "Next" to begin the Quick Setup.


5) You may choose to change the admin password in this step. Choose Next when done.


6) Choose "Client" as the operation mode and press Next.


7) A list of in-range WiFi networks are displayed. Choose "Connect" next to the network you will connect the eGauge to.


8) Enter the password for the WiFi network and choose Next.



9) Choose "Smart IP" for the LAN type. This will automatically assign the admin interface an IP address from the main network, and any eGauges connected to the Ethernet port will obtain an IP address from the main network. Press Next to continue.


7) You can review the configuration and press Finish to save and reboot.


Below shows the setup of an eGauge connected to a TP-Link TL-WR802N bridge connected in client mode on a WiFi network. The network uses the 172.17.2.* network. The WiFi bridge was assigned 172.17.2.180 while the eGauge was assigned 172.17.2.182:

Comet T4411 Temperature Sensor (Modbus RTU)

Overview

This product is not fully supported by eGauge Systems. Information here is provided as-is.

The T4411 Temperature Sensor from Comet can be used to read temperature in outdoor installations or where a sensor meeting IP65 requirements must be used. The T4411 uses an RS485 interface, and as such requires either a BF430 serial to Ethernet adapter (when using the EG30xx or EG4xxx model lines) or an eGauge serial to USB adapter (EG4xxx with USB ports only). Both pieces of hardware can be purchased directly through eGauge Systems. Steps highlighted in green apply only to the BF430, while steps highlighted in blue apply only to the USB485 adapter. Any other steps are required regardless of which adapter type or eGauge model is used.

The information below is intended to provide an overview of the correct wiring, communication settings, and eGauge configuration. Additional steps may be required if the BF430 is not purchased directly through eGauge. eGauge systems can only provide limited support for the T4411 and BF430. Advanced questions may need to be addressed directly to Comet (for the T4411) or Chiyu (if using a BF430). 

While these instructions are for the Comet T4411, most other Comet sensors should work with the eGauge. However, there may be differences in configuration, installation, required input power, etc. eGauge Systems cannot guarantee that every Comet sensor will work as expected. Please contact eGauge support if using a different sensor at support@egauge.net.

 

Installation and wiring

Serial to Ethernet adapter (BF430) - EG30xx and EG4xxx

The BF430 can power the T4411 directly using the included 12V 1A power supply. No additional power supply is needed in this configuration. Connect the BF430 to power using the supplied DC adapter. 

Connect the wiring between the T4411 and BF430 as follows:

T4411 BF430
B (-) 485-
A (+) 485+
GND 9~30V-
U+ 9~30V+

Make sure the toggle switch on the BF430 is set to "485".

The BF430 needs to be connected via Ethernet to the same network used by the eGauge. We recommend connecting the eGauge to the network via Ethernet as well - PLC or WiFi can cause issues with latency.

 

Serial to USB adapter (USB485) - EG4xxx with USB port only

With a serial to USB adapter (USB485), the T4411 will require an external power supply (check the T4411 documentation for acceptable voltage ranges; as of the time this article was written 9-30VDC is the standard). The 12Vdc power supply sold by eGauge systems will work in most cases. Connect the USB485 to the eGauge using the provided USB cable (untested cables may cause problems or may not work at all).

Connect the wiring between the T4411 and USB485 as follows:

T4411 USB485
B (-) D-
A (+) D+
GND ⏚ terminal (ground)

The T4411 will need an external power supply with this configuration. The 12Vdc power supply sold by eGauge Systems will work, or a suitable power supply rated to provide 9-30VDC can be used. Connect the power supply as follows:

T4411 9-30VDC Power Supply
GND negative side of power supply
U+ positive side of power supply

Make sure the termination switch on the USB485 is set to "ON"

Connect the USB485 to the USB port on the eGauge. Make a note of whether USB1 or USB2 is used.

Sample wiring for the Comet T4411. T4411 shown with faceplate removed.

 

Third party device configuration

 

Verify T4411 settings

The Comet sensor default serial settings are as follows:

Baud: 9600
Data Bits: 8
Parity: None
Stop Bits: 2
Modbus ID/slave address: 1

These settings can be changed using the free TSensor software available through Comet. eGauge Systems does not support or distribute this software. For assistance with the TSensor software, contact Comet directly. If using multiple Modbus devices on a single RS485 chain, each device must have a unique Modbus slave address.

 

Verify BF430 settings

The settings provided on the BF430 should be fine if purchased through eGauge. If configuring manually or if in doubt about the settings, connect the BF430 to the local network and use a computer to access the BF430 configuration page. The default credentials are user: admin pass: admin.  Make sure the physical toggle switch on the BF430 is set to "485".

Click "Serial Type" from the menu on the left.

Make sure the following settings are in place:

Serial Type = RS485
Baud Rate = 9600 (selected in the dropdown, leave the user defined baudrate as "0")
Data Bits = 8
Parity Check = None
Stop Bits = 1
Flow Control = None
All other settings should be "0"


Verify USB485 Settings

The USB485 is not user-configurable, and has no settings to adjust. However, the termination switch should be set to "ON".

 

eGauge configuration

 

Create a Modbus map (Firmware 4.1 or later)

For instructions on creating an inline definition, see this section. Note that inline definitions are no longer recommended for use from firmware 4.1 onward.

Open the eGauge UI using the web browser of your choice. Navigate to Settings -> Installation. Under Remote Devices click "Modbus Map" - a new page will load.

Click the image-1623254057280.png icon in the top right corner of the page to create a new map. Name the map appropriately (in this example, we'll use T4411 as the map name - shorter is generally better). 

Next, click the options button. Add the following options:

"Default unit number" should be set to 1 (assuming the default Modbus ID is set on the Comet sensor)
"Default serial-port parameters" should be set to 9600/8n1 (assuming default serial settings are set on the Comet sensor)

IMT Weather Station (Si-RS485TC-2T-v-MB)

Overview

The IMT Weather Station model Si-RS485TC-2T-v-MB (referred to as the IMT sensor for the remainder of this article) is a high accuracy irradiance and cell temperature sensor. Optional attachments can be connected to monitor windspeed and ambient temperature. The IMT sensor is resold (not manufactured) and supported by eGauge Systems for use in applications where measuring irradiance may prove useful. The most common application would be to estimate solar production for an array of a given size using the irradiance and temperature data from the IMT sensor.

There are several IMT models available. Only the Si-RS485TC-2T-v-MB is directly supported for use with the eGauge.

The IMT sensor communicates via Modbus RTU (RS485). A RS485 to USB adapter is required for use with the EG4xxx meter line, and a serial to Ethernet adapter is required for use with EG30xx meters. Instructions for using both adapters are included in this document.

A serial to Ethernet adapter may be used with the EG4xxx meter line, but this is not recommended.

If using multiple IMT weather stations on the same serial bus, the Modbus address must be changed. See the manufacturer's information at https://www.imt-solar.com/downloads/ under "Software Si-Series" for more information.

Third party adapters may cause issues and are not supported.

Installation and Wiring

For best results, the IMT sensor must be installed in the same plane as the solar array. The sensor window should be clean and clear of any obstructions. Follow the mounting instructions included with the IMT sensor, and contact IMT directly with any questions regarding unique installation environments.

The IMT sensor has four wires and a heavier gauge wire shield connector. Depending on the application, the wire shield may or may not be used, and it is not shown in the following diagrams. If required, the wire shield should be connected to earth ground, not the RS485 ground or signal ground. Note that proper wiring is essential. Failure to wire the IMT sensor correctly will prevent the sensor from functioning and may cause damage.


 

Wiring for EG4xxx with RS485-USB adapter

The following diagram shows the IMT sensor connected to a 12Vdc power supply and RS485-USB adapter. The eGauge is not shown.

image-1619628467279.png

The wire assignments are as follows:

Black: Negative side of 12Vdc power supply
Red: Positive side of 12Vdc power supply
Orange: D- terminal on RS485-USB adapter
Brown: D+ terminal on RS485-USB adapter

The larger, thick black wire is a grounded shield and must not be connected to the eGauge, power supply or USB485 converter. Only connect this wire if you know what you are doing as improper grounding conditions can cause damage or communication issues.

Additionally, it is necessary to connect the ground (⏚) terminal on the RS485-USB adapter to the negative terminal of the 12Vdc power supply. 

A barrel connector with terminal blocks is included with the IMT sensor. Use the female side to quickly connect the IMT sensor to the 12Vdc power supply without splicing any wires. The male side can be discarded or saved for use in another project.
