How to choose barcode scanner RS232 or network port

The serial port and network port of the barcode scanner differ in the following aspects:
Communication protocol: The serial port barcode scanner uses a serial port communication protocol (such as RS232, 485 communication), while the network port code scanner uses a network communication protocol (such as TCP, UDP).
Transmission distance: The transmission distance of the serial port code scanner is relatively short, while the transmission distance of the network port code scanner is longer.
Transmission rate: The transmission rate of the serial port code scanner is relatively low, while the transmission rate of the network port barcode scanner is higher.
Stability: The stability is good since serial communication is asynchronous and communicates through handshake lines. However, network port communication greatly affects the network environment and has relatively poor stability.
Development difficulty: The development difficulty of a serial port barcode scanner is relatively low, while the development difficulty of a network port barcode scanner is relatively high.

To sum up, there are obvious differences between serial port and network port code scanners regarding communication protocols, transmission distance, transmission rate, stability, and development difficulty. The specific choice of which type of barcode scanner needs to be comprehensively considered based on the actual application scenarios and needs.
