Images are for illustration purposes only. E&OE Overview 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. Features Support USB to RS485 bidirectional conversion Fast communication, stable and reliable, better compatibility Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, lightningproof & anti-electrostatic Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage proof, improves shock proof performance 3 LEDs for indicating the power and transceiver status Specifications PRODUCT TYPE Industrial Grade USB to RS485 converter Host port USB Device port RS485 Baudrate 300bps ~ 3Mbps USB Operating voltage 5V Connector USB-A Protection 200mA self-recovery fuse, ESD protection Transmission distance About 5m RS485 Connector Screw terminal Pins A+, B-, GND Direction control Hardware automatic control Protection 600W lightningproof and surge-suppress, 15KV ESD protection (onboard 120R balancing resistor) Transmission distance About 1.2km(low rate) Transmission mode Point-to-multipoints (up to 32 nodes, it is recommended to use repeaters for 16 nodes or more) LED indicators PWR Red power indicator, light up when there is USB connection and voltage is detected TXD Red TX indicator, light up when the USB port sends data RXD Red RX indicator, light up when the device ports send data back Operating environment Temperature -15℃ ~ 70℃ Humidity 5%RH ~ 95%RH Operating system Mac, Linux, Android, WinCE, Windows 11 / 10 / 8.1 / 8 / 7 References
