Windows 7 Driver Installation
This section will guide you on how to install the PL-2303 Windows Driver. You can download the latest
Driver Installer program from Prolific Support website:
http://www.prolific.com.tw/US/ShowProduct.aspx?p_id=225 & pcid=41
Note: Please take notice of the installation order. First, run the Driver Installer Program before
plugging in the USB to Serial adapter. If you already plug the device during the driver installation, you
need to re-plug the device for Windows to enumerate the device and load the drivers installed. If your
device is embedded to the system, you might need to restart the system (or click rescan hardware
changes in Device Manager) to reload and install the driver.
The following steps will show how to install the device under Windows 7 (64-bit) OS as this is the most
inquired driver installation support received by Prolific. The procedures are the same and straightforward for all other supported Windows operating system versions.
