Description of the Configuration Method for the Industrial Modem Wireless Transmission Terminal

In the wide application of Industrial Internet of Things IIoT, Industrial Modem Data Transfer Unit wireless transmission terminal is a key device responsible for transmitting data from field devices to remote servers or cloud platforms through wireless network to achieve remote monitoring and control. For those who need to use network applications, it is crucial to understand and correctly configure Industrial Modem. The following is a detailed description of the configuration method for the Industrial Modem wireless transmission terminal.

1. Overview of Configuration Methods

Industrial Modem is usually configured in three ways: local serial port configuration, network remote configuration, and SMS remote configuration. Some specific models such as the 3180 series support this configuration. Each configuration method has its own characteristics and applicable scenarios, and users can choose the most suitable method for configuration based on their actual needs.

2. Local Serial Port Configuration

2.1 Tool configuration

Connecting equipment:

Connect the serial port of the Industrial Modem to the serial port of the computer using a serial port cable, and ensure a secure connection. At the same time, pay attention to the serial port number of the computer so that it can be selected correctly in the configuration software.

Open the configuration software:

Find the Industrial Modem configuration software in the "Configuration CD" or specified location, such as "Xiamen Caimao Industrial Modem Configuration Software VXXX.exe", and start the software.

Select product model:

In the product model selection area of the configuration software, select the corresponding "type" and "model" based on the actual model of the Industrial Modem. Please note that different models of Industrial Modem may have different interface types and configuration methods.

Set serial port parameters:

In the work area of the configuration tool, set the serial port parameters, including the serial port number and the computer serial port number connected to the Industrial Modem, the baud rate is usually 115200, the data bits are 8, the check bits are none, the stop bits are 1, and the flow control is none. After confirmation, click "Open Serial Port".

Enter the configuration state:

Power on the Industrial Modem according to the software prompts, and select "Configuration State" in the working state switching area of the configuration tool. At this time, the software will enter the configuration mode, allowing users to modify various parameters of the Industrial Modem.

Configuration parameters:Set the network parameters, data transmission mode, and working mode of the Industrial Modem in the configuration tool according to actual needs. During the configuration process, you can refer to the software's help documentation or related manuals.

Save configuration:

After configuration is complete, click "Save configuration parameters" to save all changes.

2.2 Manual configuration

Although manual configuration is relatively complex and error-prone, it may still be necessary in some cases. Manual configuration usually involves the following steps:
Open serial port tools or HyperTerminal and set the correct serial port parameters.

Power on the Industrial Modem and press a specific key, such as the "s" key, until a prompt appears to enter the configuration state.

Configure the parameters of the Industrial Modem by sending AT commands. For detailed AT command set, refer to the user manual or related documents of Industrial Modem.

After configuration, restart the Industrial Modem to make the changes effective.

3. Network Remote Configuration

After the Industrial Modem is connected to the server, it can be configured remotely through the network. The specific steps are as follows:

The server software sends a specific data packet, such as "COMMIT CONFIG", to the designated Industrial Modem, requesting to enter the network configuration state.

When the Industrial Modem returns "Remote Config Ready", it indicates that it has entered the network configuration state.

Modify the parameters of the Industrial Modem by sending AT commands. During the configuration process, it is necessary to ensure the stability and security of network connections.

After configuration, send a restart command such as "AT+RESET" to make the changes effective.

4. Remote Configuration of Specific Models Via SMS

For Industrial Modem supporting remote SMS configuration, such as the 3180 series, when the SIM card has been activated for SMS services, the parameters of the Industrial Modem can be modified by sending SMS messages. For specific formats and steps, refer to the user manual or related documentation of the Industrial Modem.

5. Precautions

Before configuring the Industrial Modem, ensure that all hardware connections such as power cords, antennas, and network cables are correct, and check that the firmware version is the latest to ensure the stability and security of the device.

Avoid configuration in harsh environments such as high temperature, humidity, electromagnetic interference, etc., to avoid affecting the performance and stability of the device.

Operate strictly in accordance with the configuration guide provided by the manufacturer to avoid misoperation and equipment malfunction.

In summary, the configuration methods of Industrial Modem wireless transmission terminals are diverse and flexible, and users can choose the most suitable configuration method according to their actual needs. During the configuration process, it is important to pay attention to the setting of various parameters and security requirements to ensure the stable and reliable operation of the Industrial Modem.
