Adopt industrial grade chip FT232, SP3485, high-speed communication is stable, reliable, good compatibility
Adopting USB-B interface and 5.0mm screw terminal, smooth plugging and unplugging, sturdy and reliable
Adopt large package components, more stable and reliable
With independent power supply isolation and signal isolation circuit
USB terminal with electrostatic ESD protection circuit, effectively preventing electrostatic damage and protecting the rear circuit and equipment
RS485 terminal with over-current protection, surge protection, lightning gas discharge protection circuitry
On-board 120R terminal resistor selector dip switch, can increase the stability of signal transmission
Baud rate support range: up to 2Mbps (in practice, the baud rate supported by the module is limited by the baud rate supported by the two ends of the access device, need to be adjusted according to the actual situation)
On-board three LED indicators, used to indicate the sending and receiving status of the circuit signals
PWR light: red, power indicator
TXD light: green, RS485 data transmission indicator, data flow: USB->RS485
RXD light: blue, RS485 data receiving indicator, data flow: RS485->USB
