RS232 RS422 RS485 to USB Converter

 The AI-7561 is a cost-effective module for transfer serial data over USB. It allows you to connect your serial devices to systems using a USB interface. Connecting the AI-7561 to a PC, you get one RS-232/422/485 port. The "Self Tuner “ chip auto-tunes the baud rate and data format to the Rs-485 network. The AI-7561 module derives the power from the USB port and doesn’t need any power adapter. It also features a high-speed 115.2 Kb/s transmission rate, and supports various independent RS-232/422/485 Ports.
