Description
The industrial USB TO RS485 bidirectional converter integrates original CH343G chip and provides multi-protection circuits. 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.
-
Support USB to RS485 bidirectional conversion
