Power supply

First, connect the power supply according to the power supply information and to the diagram.

Opening inbuilt website

Through the WAN interface

To access the built-in website, connect the gateway by WAN to the local network and enter IP address in the address window of the browser. Please note that it may take some time from powering on to booting up the system. When the LEDs next to the RJ45 socket start flashing, after about 10 seconds the built-in website becomes available.

Cellular modem

Modem

The Gateway in its basic configuration is equipped with an LTE modem that also supports GPRS and SMS functions. Different modems were used depending on the model variant. Here is a table of models.

SIM card

The Gateway supports one microSIM card, both 1.8V and 3V. The card connector is tpush-pull type. When installing the SIM card, pay attention to the correct insertion of the card.

The card can be inserted the other way around and you can have the impression that you have inserted it correctly. So take a close look at the above drawing.

Using Cellular Network

To activate the LTE modem, go to Network > Interfaces and select the lte tab there.

Mostly the network operator requires you to enter the APN, sometimes it also requires a username and password. Enter the required data and save.

Then go to System > Custom Commands and click on Start modem.

The modem will start up and connect to the Internet. To check if it is working properly and what the signal is, go to Modem > Information about 3G/4G/5G connection.

Cellular modem ON on start

To make the gateway automatically connect to the Internet after startup, you need to add a modem startup in the System > Startup section under Local Startup, add a line before line 'exit 0'. /usr/commands/start_modem.sh. Then save the changes. After each reboot, the gateway will automatically start the modem.

SMS

To test the SMS operation, the gateway has an SMS interface installed. Under Modem > SMS Messages. There you can check sent and received SMS. Be sure to enter the phone number together with the country prefix, but without the + sign. The maximum number of characters is 160. The system does not support alphabets such as devanagari. The maximum number of messages in the inbox is 20.

For send SMS go to Send Message tab.

System statistics

The gateway has a built-in real-time statistics system under Status > Realtime Graphs and accurate statistics with selectable time range under Statistcis > Graph. You can check CPU load, memory usage, network load, etc.

Modbus

The Gateway has a very advanced Modbus application with a convenient graphical interface. Below are the capabilities of the application:

Modbus TCP/IP and Modbus RTU support.
Any number of serial ports
Support for external USB/serial interfaces
JSON, TCP/IP and MQTT string formation
Data logging in the event of no connection to a server
Storage of all data in internal memory

Using the terminal

The AG-702 has a built-in bash terminal. With it you can execute all commands in the OpenWRT system. To enter the terminal, go to the tools > terminal section on the built-in website. The default password is the same root/root.

Reset and default

Make factory default

To reset the system to factory settings, hold down the "Default/Reset" button for more than 5 seconds while the device is operational. During the factory reset, all LED indicators will light up for 2 seconds.

Reset device

To restart the gateway without disconnecting the power supply, press and hold the "Reset/Default" button for less than 5 seconds. During the restart, 4 LED indicators will light up for 1 second (IN-1, IN-2, RS485, RS232)

Do not hold the button for more than 5 seconds, as it will trigger the gateway to restore default settings.

Storage overlay

How to make a storage overlay

AG-207 has a 512MB NAND memory in addition to the 64MB FLASH memory. It is possible in a very simple way to increase the memory by extending the system partition to the so-called overlay.

To do this, go to the System > Custom Commands section and select Format NAND and create as EXTROOT. Then wait a while for the operation to complete when on boottom of page "Waiting for command to complete..." will close. The formatting process takes a few minutes.

Then, to verify, go to System > Mounting Points and see if we have the overlay done correctly.

You can also restore partitions to their previous state and format the NAND as data memory. For this isn custom command section click on Delete EXTROOT from NAND and after that Format NAND and mount as /nand in root file.
