Quick Overview
This DIYables USB to RS232 cable features an HL-340 adapter chip that enables seamless USB to serial port communication for legacy RS232 devices. The adapter provides a virtual COM port on modern computers without built-in serial ports, allowing connection to industrial equipment, modems, serial printers, and other RS232 devices.
The cable is equipped with a 128-byte TX buffer and 512-byte RX buffer for smooth and efficient data transfer, along with auto-handshake protocol support for streamlined communication without additional setup. The enhanced EMI (electromagnetic interference) design ensures stable and reliable data transmission in various industrial environments.
Ideal for legacy RS232 devices, industrial equipment communication, serial modems, PLC programming, CNC machine control, GPS modules, barcode scanners, serial printers, and any application requiring USB to RS232 serial connectivity on modern computers.
