3.2 I-7561 Pin Assignment and Specifications
Introduction
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 extra
high-speed RS-232/422/485 ports. 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 (when you
use I-7561, you should connect power ground to other
modules). It also features a high-speed 115.2 Kb/s
transmission rate, and supports various O.S.
independent RS-232/422/485 Ports.
