Introduction
I-7561/I-7561U is a commercial module for transferring serial data via USB. It lets you connect your serial devices to systems that use a USB interface. Connecting the I-7561/I-7561U to a PC, you get one RS-232/422/485 port. The I-7561 contains “Self-Tuner” chip auto-tunes the Baud Rate and data format to the RS-485 network. The I-7561/7561U module derives its power from the USB port and doesn’t need any power adapter.
