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/RS485/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.
3.3.3 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 interface, 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 transmits 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 management 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.
3.3.3 Httpd Client function usage

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.

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

3.3.1 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:

Figure 27 Serial port information page

MPort Series Unser Manual
3.4 Network Address
The network address module includes: the IP address of the network, the subnet mask, and the default gateway.
3.4.1 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.
Figure 28 Network address interface
 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 address is assigned by the Network Information Center (NIC) of the US National Defense Data Network. In order 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 serial server and switch to a waiting page as shown in Figure 29.

MPort Series Unser Manual
Figure 29 The waiting interface diagram after the user modifies the address
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.
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.
3.5 User Password
The user password module is mainly used to modify the password.
3.5.1 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.

MPort Series Unser Manual
