Usb 485 Communication Module Bidirectional

USB to 485 Communication Module



All use original chips! USB to 485 Communication Module All use original chips! All use original chips!

Industrial-grade protection: TVS transient suppression protection, electrostatic ESD protection, surge protection, AB signal line short circuit and power supply short circuit protection (short circuit will not burn)

Transmission distance up to 1200 mete (tested at 9600bps)

Support baud rate of 921600, which is much higher than 115200. Paired transmission uses a higher baud rate, The Lead PINS include: A +, B-, GND ,GND,5V0;I

Multiple systems support hot-swap, support win98/CE/2000/2003/2008/XP/WIN7/WIN8/WIN10/VISTA/LINUX/MAC OS X systems, USB interface can be hot-swapped

Automatically identify and control the data transmission direction without any handshake signal (such as RTS, DTR, etc.) and jumper settings to achieve mode conveion, ensuring compliance with existing communication software and interface hardware.

With TXD, RXD indicator light
