1-port serial server configuration tool operating instruction
- Main screen.
Open the CD or configuration tool, double click to open the serial server configuration tool, the following interface
Note: The main interface of the configuration tool mainly includes two parts: the device list and configuration information, and the version number of the current tool at the bottom right, subject to actual use - Device List:

- There are three main functions in the device list for ip address processing
- Search: After confirming that the serial server is connected correctly and running normally, click Search to get the current ip address and MAC address of the device
Add: Click Add, enter the ip address, you can directly add the ip to the list of devices - Delete: select the ip address you want to delete, you can move the ip out of the device list, the default is to delete all
- Note: When the device is not fully operational or failure, the search ip will not be successful
- Search: After confirming that the serial server is connected correctly and running normally, click Search to get the current ip address and MAC address of the device
- about the search

By searching the device, after being selected, you can add to the device list and modify the ip address and other operations, the default add to all add
(This function is mainly to facilitate the user to serial port server and host ip in the same network segment, in order to read and write configuration) - Configuration Information

- Configuration Information Description
- There are three main functions in the device list for ip address processing
Read configuration
After confirming that the serial server is connected correctly and running normally, select the serial server device and click Read Configuration to get the configuration information as follows.
Write configuration
First select the configuration information that can be changed and selected to make changes
After the changes are confirmed, click Write Configuration, which will save the configuration information to the serial server device
Firmware Upgrade:Different from the application mode upgrade mode, click and confirm will enter the upgrade interface as shown below, you can upgrade the device firmware (this mode will interrupt the device that is communicating)
Note: About the upgrade
Click test link, it shows that the link is normal, then you can select the upgrade file, click upgrade after selection, when the progress is completed 100%, the upgrade is successful. In addition, the firmware can support restoring factory settings in version V26 or above, all configurations will be restored to the factory state.
Note: The upgrade status will be different from the application status. When the device is in the upgrade status, please click back to the application mode after the upgrade is completed, wait until you enter the application mode, and then operate to avoid the device abnormality.
Device Mode
Currently the device supports nine specific modes such as VCOM, UDP, TCP Sever, TCP Client, MCP, Modbus, etc. The default mode is VCOM and the port number is fixed at 966
| Mode | Mode Description |
| VCOM | VCOM is a virtual serial port mode, you can virtualize the serial server as a serial device for communication, the port number in this mode is fixed at 966 |
| UDP | The UDP mode of operation is subordinate to the UDP protocol, a connectionless mode that provides a simple, unreliable, thing-oriented messaging service |
| TCP Mode | The TCP mode of operation is subordinate to the TCP protocol, which is a connection-oriented, reliable and transparent transmission service, including the TCP Sever and TCP Client modes; in both modes, the corresponding IP and port numbers can be filled in to communicate with each other. |
| Modbus Mode | Modbus operating mode is subordinate to the Modbus protocol and is an operating mode that supports the Modbus protocol |
This note focuses on the virtual serial port mode VCOM
Virtual serial port mode
Double click on the virtual serial port software VCOM to get the following main interface
Under the Remote Device Management menu, click Add Device in the first step to get the following screen, click Search in the second step to get the following devices, and in the third step, check our devices and add them. 
Click COM Mapping to create a virtual serial port, starting from COM1 by default, you can click COM1 to change the serial port number

Create successfully
Under Device Manager, you will see that there is already a serial port number Select the serial port number for normal communication
1-Port Series Serial Device Server Troubleshooting Instructions
- Click search can not search the IP address of the serial server
- , first check whether the physical connection is normal, the network cable and power supply is connected, observe the power indicator, LINK light, ACT light is normal (connected to the 10M network, this light does not light, 100M light)
- the host network card is available, can not communicate with other local or other hosts.
- close all the tools and software that can block the broadcast packet (do not open the firewall that comes with the system)
Your Reliable Partner in Industrial IoT
- Cannot read or write configuration
- Ensure the normal operating status of the network (whether the ACT light and RUN light are normal)
- Ensure that the serial server device and the connected host are in the same network segment, and whether the IP can ping through
- Ensure that the serial server is in application mode
- if the above can not solve the problem try to power off and restart, if necessary, restore factory settings
- Cannot send and receive data
- Ensure that the serial port can be opened normally
- Observe whether the system light is flashing fast or slow, flashing fast for the data sent and received, such as no flashing fast check the connection between the serial port and the upper network, and the bottom serial device to check the wiring
- Forget the previous configuration information
- Determine the configuration information by reading the configuration, if the ip address is not remembered, then you can search for
- Transmitting and receiving data is messy code
- Check if the wiring is correct,our 485 wiring is 1A+,2B-.
- Check if the line distance has exceeded the standard distance and the quality of the line (also by lengthening the line transceiver or optical isolation)
- Check whether the baud rate set matches the bottom device
- Separate from the client’s top software, use the network or serial debugging assistant can receive normal data, if you can receive normal data, may not be compatible with the top software
- If none of the above ways can solve your problem, please contact the manufacturer
