Modbus function usage
Take MPort3101-I as an example below, other models are similar. Simulate the master with software such as Modbus Poll, and simulate the slave with software such as Modbus Slave.

Modbus Master

Take Modbus_RTU_Master as an example (Modbus ASCII Master is the same):
Configure the “serial port parameter” of the serial server to 9600-8-N-1, the working mode in”network parameters” is Modbus RTU Master, and the network address in “Network Connections” is config-ured as the IP and port of the slave. The physical connection is described as follows:

• Serial port: connect to the host
• Network port: connect to the slave

Modbus Poll software configuration:
Open the Modbus Poll software, go to “Connect” -> “Connect”, and the connection parameters are configured as follows:Read parameter configuration: the slave ID is 1, the function code is 03, the starting address of the register to be read is 0, the number of registers to be read is 10, and the cycle reading interval is 1000ms. Open Modbus Slave software: Go to “Connect” -> “Connect”, and the connection parameters are configured as follows: Slave device definition configuration: the slave ID is 1, the function code is 03, the register start address is 0, and the total number of registers is 200. Double-click the cell of Modbus Slave software and modify it to auto-increment mode, you can see that the register cell of Modbus Poll software also changes value automatically. Indicates that the device communication is normal.

Modbus Slave
Take Modbus_RTU_Slave as an example (the same applies to Modbus ASCII Slave):
Configure the “serial port parameter” of the serial server to be 9600-8-N-1, the working mode in the “network parameter” is Modbus RTU Slave, and the local port is 502. The physical connection is described as follows:

• Network port: connect to the host
• Serial port: connect to the slave

Open Modbus Poll software: Go to “Connect” -> “Connect”, and the connection parameters are configured as follows: Read parameter configuration: the slave ID is 1, the function code is 03, the starting address of the register to be read is 0, the number of registers to be read is 10, and the cycle reading interval is 1000ms. Open Modbus Slave software: Go to “Connect” -> “Connect”, and the connection parameters are configured as follows: Slave device definition configuration: the slave ID is 1, the function code is 03, the register start address is 0, and the total number of registers is 200. Double-click the cell of Modbus Slave software and modify it to auto-increment mode, you can see that the register cell of Modbus Poll software also changes value automatically. Indicates that the device communication is normal.

Attention

1. The port numbers 57050 and 57051 have been used by the system. When configuring the port numbers, please do not reuse them.

2. The device and the remote device must have the same baud rate, parity bit, data bit and stop bit.

3. If the working mode of the device is UDP, the remote device must also work in UDP mode; if the working mode of the device is TCP_Client, the remote device must work in TCP_Server mode; if the working mode of the device is TCP_Server, the remote device must work in In TCP_Client mode.

4. When you need to use long frame data frequently or have high data transmission requirements, please adjust the baud rate and lengthen the sending interval appropriately to prevent the slow serial port from causing messy codes or packet loss.

5. When configuring the device, the user should ensure that the external RS-232/RS-
   485/RS-422 device stops sending data to the serial server to avoid garbled characters.

6. When Modbus_ASCII_Master turns on the transparent transmission mode, it only supports reading of up to 60 registers. 7. Mport3101 is affected by the hardware configuration, Modbus ASCII protocol transmission only supports use below 19200 baud rate.

RealCOM function usage
In RealCOM mode, the serial server cooperates with the operating system installed with RealCOM driver software. The RealCOM driver software maps the serial server’s serial port to the host’s local COM in-terface, so that the original serial device software or communication module on the host can be used directly without modification. The RealCOM driver software transparently transmits the data received by the virtual COM interface on the host to the serial server in the form of TCP/IP. The serial server transparently trans- mits the data received from the serial port to the virtual COM interface of the host computer in the form of TCP/IP.
The serial server supports three RealCOM protocols: RealCOM_MCP mode is compatible with Moxa’s drive management software; RealCOM_CCP mode is compatible with Kang Hai’s serial manage-ment tool; RealCOM_MW mode supports Maiwe’s MWVirtualCOM software.

How to use Maiwe RealCOM:

1. The WEB of the serial server is configured as RealCOM_MW mode;
2. Install and open Maiwei virtual string management software;
3. Click [Add Device], and the add serial mapping interface will pop up;
4. Click [Scan], the software will scan the serial server devices in the local area;
5. According to the MAC address and IP address, select the corresponding serial server device;
6. Click [String Mapping] and wait for the creation of a local virtual string;
7. Connect the string of the serial server with the real string on the host, and use the string debugging tool to open the string created by the virtual string management software and the real string on the host, one of the two Send data to each other for testing.

Httpd Client function usage
This function is that the serial server submits the data received by the serial to the HTTP server in the form of HTTP. If the HTTP server has data to be sent, the string server will transparently transmit the data of the HTTP body to the string.

Specific usage method:

1. Select “Httpd Client” as the work mode;
2. Fill in the HTTPD address, that is, the address of the HTTP server, which can be an IP address or a domain name (the ability to connect to foreign countries is required);
3. Fill in the HTTPD port number;
4. The HTTPD method needs to fill in the correct URL path, and select the GET or POST method as needed;
5. Fill in the HTTPD request header as needed;
6. Finally, click the Configure button to save the parameters.

WebSocketClient function usage
This function is that the serial server acts as a WebSocket Client, and transparently transmits the data received by the serial to the WebSocket server in hexadecimal format. The WebSocket server can also send data to the serial device at any time.

Specific usage method:

1. Select “WebSocket Client” as the work mode;
2. Fill in the WebSocket server address, which can be an IP address or a domain name (you need to have the ability to connect to the outside world);
3. Fill in the WebSocket server port number;
4. WebSocket method needs to fill in the correct URL path;
5. You can select the WebSocket Ping time interval according to your needs, fill in 0 to indicate not to use the Ping function; 6. Finally click Configure button to save parameters.

Attention

1. The port number 80, 4500, 4800, 57050, 57851, 57850, 57851 has been used by the system. When configuring the port number, please Do not use repeatedly.

2. The device and the remote device must have the same baud rate, parity bit, data bit and stop bit;

3. If the operation mode of this device is UDP, the remote device must also operate in UDP mode; if the operation mode of this device is TCP_Client, the remote device must operate in TCP_Server mode; if the device operates The mode is TCP_Server, and the remote device must work in TCP_Client mode.

4. If the operation mode of this device is UDP multicast mode, the same multicast ad-dress can only be used once, and no multicast address is allowed.
   The address is used in different serial configurations.

5. When you need to use frame data frequently or have high requirements for data transmission, please adjust the baud rate and the sending interval appropriately. The slower anti-crossover speed causes garbled characters or packet loss.

6. When configuring the device, make sure that the external RS232/485/422 device stops sending data to the serial server to avoid garbled characters.

7. When Modbus_ASCII_Master turns on the transparent transmission mode, it only supports reading of 60 registers at most.

8. Mport3101 is affected by the hardware configuration, Modbus ASCII protocol trans-mission only supports the use below 19200 baud rate.

9. Affected by the serial rate, when Modbus data timeout occurs, the web should be configured with appropriate modbus receiving timeout
   At the same time, the read timeout time of the host computer should be appropriately extended according to the baud rate.

10. To use the RealCOM function, the firmware version of the serial server must be V1.x.9.210512 and above, and the software version of the virtual serial tool must be V1.0.300.05 and above.

Serial Port Information
The serial port information module includes two parts: serial port information and network connection information.

Serial port information
The serial port information page is used to display the current connection information of the serial port as shown in Figure 27:

Network Address
The network address module includes: the IP address of the network, the subnet mask, and the default gateway.

Network address

The function of this function is to assign a designated IP address to the Mport series serial server.
The default IP address of the serial server when it leaves the factory is 192.168.16.253. The network address configuration page is shown in Figure 28 .

• Network protocol: select static address or DHCP.

• IP address: IP address is a 32-bit address assigned to devices connected to the Internet. The IP address consists of two fields: the network number field (Net-id) and host number field (host-id). The IP ad-dress is assigned by the Network Information Center (NIC) of the US National Defense Data Network. In or-der to facilitate the management of IP addresses,IP addresses are divided into five categories: Class A, B, and C addresses are unicast addresses; Class D addresses are multicast addresses; Class E addresses are reserved addresses for future special purposes. The IP addresses currently in large numbers belong to three types of addresses: A, B, and C.

• Subnet mask: The mask is a 32-bit number corresponding to an IP address. Some of these numbers are 1, and the others are 0. The mask can divide the IP address into two parts: the subnet address and the host address. The part of the IP address corresponding to the 1 bit in the mask is the subnet address, and the other bits are the host address. The mask for class A addresses is 255.0.0.0; the mask for class B addresses is 255.255.0.0; the mask for class C addresses is 255.255.255.0.

• Default gateway: The default gateway in the host is usually called the default route. The default route
  (Default route) is the route chosen by the router when no other route exists for the destination address in the IP packet. All packets whose destination is not in the router’s routing table will use the default route. This route usually connects to another router, and this router also processes data packets. If you know how to route this data packet, the data packet will be forwarded to a known route; otherwise, the data packet will be forwarded to the default Routing to reach another router.

• DNS: The IP address of the DNS server. When the device uses a static IP address, the user is required to fill in this item. If a specific DNS server is not used, the default gateway IP address is generally sufficient. Whenever users modify the address settings, they need to click the button to submit to the Mport series se-rial server and switch to a waiting page as shown in Figure 29.

When the progress bar in the screen is finished, the Mport series serial server restarts the Web server, and the user needs to log in again.

Attention

1. When entering the waiting page after configuring the IP, do not power off or perform other operations to avoid failure of the IP address modification.
2. The configured IP address and the default gateway must be in the same network segment.
3. If the device uses DHCP to obtain an IP address, after the device restarts, the user needs to use the company’s network management assistant to search for the device to accurately know the new IP address of the device.

User Password

The user password module is mainly used to modify the password.

User password
The Web server of this Mport series serial server provides users with three different permissions. The first type is for visitors, which can only view the current various configurations of the serial server, but cannot modify the configuration. The user name and password are both “none” and cannot be modified; the second is for ordinary users, which can configure various functional parameters of the serial server. The user name is admin and cannot be modified. The initial password is “admin”, which can be modified on this page; the third is the administrator, the account has the highest authority, and when the password of a common user is forgotten, the administrator can log in and modify it The password of this machine, the user name is fixed as “admin”, and the password is the last six digits of the machine’s MAC address. (If you don’t know the MAC address of the machine, you can log in as a guest to view it first).

The login password must be legal characters, consisting of 4-12 English letters (case sensitive) and numbers. When changing the password, you need to enter it twice, and you must ensure that the passwords entered twice are consistent. The page is shown in Figure 30.

• User name: The user name of this machine is fixed as “admin” and cannot be modified.
• New password: Set the user password of this group, consisting of 4-12 English letters (case sensitive) and numbers.
• New password confirmation: Repeat the password to prevent entering the password incorrectly.

Attention

1. The passwords of ordinary users are modified on this page.
2. For security, it is recommended to change the default password after logging in for the first time.

System Information
The model, name, and number of the device can be configured on the system information page, as shown in Figure 31.

• Device model: Users can customize the model of the Mport series serial server.
• Device name: The user can customize the name of the Mport series serial server.
• Device platform: the name of the manufacturer’s platform, which cannot be configured by the user.
• Device Number: The serial number of the serial server is not configurable by the user.

System Management
This page can perform some system operations on the Mport series serial server, including restarting, restoring factory configuration, and upgrading. It is recommended that users use it with caution. Improper operation may damage the serial server. The page is shown in Figure 32.

• Device restart: This function is used to restart the Mport series serial server by software. Before the serial server is completely restarted, the device does not work and cannot forward any data packets. This restart is different from the hardware reset of power-on restart, but the serial server system software is reset, just like the “warm restart” of the windows operating system. The biggest advantage of this function is to provide a function of remotely restarting the serial server. As long as the user can access the serial server remotely, it can be restarted remotely. Click on “Start” Button, the page pops up a prompt box, as shown in Figure 33, click “OK” to jump to the waiting page, after the progress bar in the page is read, the serial server restarts to complete.

• Restore the factory settings of the device: This function is used to restore the Mport serial server to the factory settings and automatically restart the serial server at the same time. Before the serial server restarts successfully, the serial server does not work and cannot forward any data packets. This function is to restore the factory default configuration value once the user sets the wrong parameter and causes the serial port server to work abnormally. There is the option of “Keep the current IP address” on the right. When checked, the current IP address will be retained. If not checked, the IP address will also be restored to the factory default address: 192.168.16.253. Click the “Start” button, and a prompt box will pop up on the page, as shown in Figure 34. Click “OK” to jump to the waiting page. After the progress bar in the page is read, the serial port server is restored to its factory configuration.

• Device upgrade: This function is used to upgrade the software of the Mport series serial server. Users can get the upgrade program of the serial server through email or our company’s website. Please pay attention to the matching of the device model and version, and use the unmatched upgrade program Will cause the upgrade to fail. After the user gets the upgrade program, click ‘’Browser”.
  Click the “Start” button to select the upgrade program, and then click the button, the page pops up a prompt box, as shown in Figure 35, click “OK” to jump to the waiting page, after the progress bar in the page is read, the serial server software upgrade is completed.

• Device restart without data: This function is used for the serial port server of the Mport serial server without any data transmission or reception for a long time, and the serial server automatically restarts. If the restart time is set between 0 and 59 seconds, this function does not take effect. Only when the time is set to be greater than or equal to 60 seconds, the restart function of the device without data will take effect. The default value is 3600s, which is one hour.

Attention

1. Restoring the factory settings will cause all the settings to be restored to the state just left. If you want to keep the IP, please check the “Retain the current IP address” on the right, otherwise the IP address will also be restored to the default configuration 192.168.16.253.
2. Do not upgrade the device casually. When the device needs to be upgraded, you must make sure that the upgrade file is correct, otherwise it is easy to damage the software of the device and cause the Mport series serial server to malfunction.
3. Please do not operate the Mport serial server during the upgrade process, and it is forbidden to click on the serial server web page. If the upgrade is interrupted due to misoperation, please restart the serial server and try again.
4. Power failure is not allowed during the entire upgrade process. Power failure may cause permanent damage to the Mport series serial server. If the power is interrupted during the upgrade, please mail the product to our company immediately for possible solutions.
5. To set restart parameters for devices with no data, avoid using the Chrome 68 version of Google Chrome, otherwise there will be a problem that the configuration page cannot respond.
