The power supply and signal are completely isolated, providing enhanced anti-interference capabilities and safer operation. This USB to RS485/422 converter enables PC users to connect their -485/422 devices to systems with a USB interface. By connecting the converter to a PC, there is no need to open the chassis or turn off the PC for installation. With this converter, users instantly gain an additional high-speed -485 or -422 port. Additionally, since the power is sourced from the USB port, there is no need for cumbersome power adapters, making it particularly suitable for PLCs, printers, POS systems, and industrial control devices. Power supply: USB 5V Transmission distance: up to 1200 meters (9600bps) Chip solution: CH340E Communication protocol: pure hardware device, not restricted by agreements Baud rate: up to 256000bps, supporting mutual transmission for higher baud rates The power supply and signal are fully isolated, enhancing anti-interference performance Protection: TVS transient suppression protection, electrostatic ESD protection, surge protection, short signal line, and short-circuit protection with power supply (short-circuit without damage) Temperature range: -40 °C to 80 °C Supported systems: hot-swappable; compatible with various operating systems including Win98, 2000, 2003, 2008, XP, WIN7, WIN8, WIN10, VISTA, LINUX, and OS X; USB interface supports hot swapping. Automatically identifies and controls the data transmission direction without any handshake signals (such as DTR, etc.) or jumper settings for mode conversion, ensuring compatibility with existing communication software and interface hardware.
