Chapter 1 Before Using the Product
1-1. Overview
This unit is an interface converter that converts PC’s USB port to an RS-422, or RS-485
port. A photo coupler and an isolation transformer electrically isolate the USB port from
the conversion port, which is ideal for FA equipment and medical equipment that require
high safety and reliability. It is able to access the USB port as a COM port using the
application software by virtual COM port driver.
