Industrial USB TO RS485 Bidirectional Converter, Onboard Original CH343G, Multi-Protection Circuits And SP485EEN Chips, Providing Better Stability And Compatibility, Built-In Lightningproof Tube, Resettable Fuse, ESD And TVS Protection Circuits, Etc.The USB Signal Can Be Converted Into A Balanced Differential RS485 Signal And The Transmission Rate Is Stable. The Reliable Speed Is 300bps ~ 3Mbps, The Transmission Distance Is About 1.2km For RS485 And About 5 Meters For USB.CH343G is a USB bus adapter chip, which can convert USB to a high-speed asynchronous serial port, supports automatic identification and dynamic self-adaptation of communication baud rate of 115200bps and below, and provides commonly-used MODEM contact signals to expand asynchronous serial ports for computers. It can upgrade a common serial device or MCU directly to a USB bus.
