INTRODUCTION
Thank you for purchasing the TruLink USB to 4-Port Serial Adapter. This USB to 4-Port Serial Adapter
provides an external plug-and-play solution to add up to four RS-232 serial devices to a USB-enabled
computer. Many newer computers, particularly laptop computers and handheld devices, no longer include
the legacy serial ports, and desktop computers have reduced the number of serial ports supported. Users
with serial devices may find themselves unable to communicate with installed equipment. The USB to 4-Port
Serial Adapter is a great solution for connecting those legacy devices to a new computer. The four DB-9
serial ports ensure you’ll have the connections you need, when you need them. We recommend that you
read this manual thoroughly and retain for future reference.
Note-Illustrations/Screenshots in this user guide are taken from Windows XP operating system. Other operating systems will
appear different.
