Working on four-channel USB to RS232/RS422/RS485
Currently, I’m working on making hardware for a four-channel USB to RS232/RS422/RS485 interface, A four-channel USB to RS232/RS485/RS422 converter is a versatile communication device that allows a single USB port on a computer to interface with up to four independent serial channels simultaneously. It supports multiple industrial serial standards, making it suitable for connecting a wide range of equipment such as PLCs, sensors, industrial controllers, modems, and embedded systems. By consolidating multiple serial interfaces into one compact USB device, it simplifies wiring, reduces hardware costs, and improves system scalability. Each channel typically operates independently, offering configurable baud rates, data bits, parity, and flow control to ensure reliable data transmission. Designed for industrial and commercial applications, four-channel USB to RS232/RS485/RS422 converters often include features such as galvanic isolation, surge protection, and robust metal enclosures to with...
