  • for low traffic and low speed application
  • mcu, RS232, RS485/RS422, slave usb all can be interchangeable.
  • usb side
    • support platform in linux with usb driver
    • simulated uart programming in application level
  • rs232 to rs485 side
    • Tested max. baudrate is 115200(i assume more high baudrate can be accepted, but i have not tested)
