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 or two extra
high-speed RS-232/422/485 ports. Like our I-7520A, the I-7561
contains ˇ§ Self Tuner ˇ§ 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 doesnˇ¦t need any power adapter. It also
features a high-speed 115.2 Kb/s transmission rate, and supports
various O.S. independent RS-232/422/485 Ports.
