Introduction
This Adapter is designed to make massive data communication become quick and simple through
an USB port of PC. By taking the advantage of the feature of USB port and Serial port, it provides
an easier and more convenient connectivity than ever for efficient and friendly interaction between
RS-422 or RS-485 devices and your computer systems.
The interface of RS-422 and RS-485 are very common adopted in data acquisition world. Both
standards feature reliable performance of full-duplex or half-duplex multi-drop communication
network with faster data rates and longer communication distance than RS-232. Application
devices include telecommunication units, LAN, data concentration, data multiplexers, ISDN, POS,
industrial controls, etc.

Windows 98SE Installation Guide
If a device of the same type has been installed on your machine before and the drivers that are about to be
installed are different from those installed already, the original drivers need to be uninstalled. Please refer to
the uninstalling instruction.
Download the latest available drivers from the FTDI website and unzip them to a location on your
PC.
Connect the device to a spare USB port on your PC. This will launch the Windows Add New
Hardware Wizard. Windows may display a message reading "Building driver database" at this point
which may take a few minutes to pass. Click "Next" to proceed with the installation.
Select "Search for the best driver for your device. (Recommended)." as shown below and then click "Next".
