The I-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 I-7561 to a PC, you get one RS-232/422/485 port. Like our I-7520A, the I-7561 contains “ Self Tuner “ This chip auto-tunes the baud rate and data format to the Rs-485 network.The I-7561 module derives the power from the USB port and doesn't need any power adapter. It also features a high-speed 115.2K bps transmission rate, and supports various O.S. independent RS-232/422/485 Ports.
