Serial server module application
(1) Remote attendance: The attendance machine and the serial port server can transmit the attendance data to the server, and it is very convenient to count the attendance status of offices across the country.
(2) Unattended weighing: The serial port server can be used to connect weighing instruments, receipt printers, gates and other supporting equipment to the LAN. Centralized control and data statistics management can be completed using a LAN computer.
(3) Remote control PLC: PLC adds a serial port server, and the programming software is combined with a virtual serial port, thus realizing remote programming of the PLC.
