window to guide you through the initial configuration process. Select the option “No, not this time”
and click on “Next” button to continue.
The following wizard helps you install the software for “High-Speed USB Multi Serial Compound
device”. Select the option “Install the software automatically” and click on “Next” to proceed
further.
As specified in earlier section, a warning message will popup informing the user that the software
being used has not passed the Windows Logo testing. You can ignore the warning message by

clicking on the option “Continue Anyway”.
The following window conveys that the OS had finished the software installation for “High-Speed
USB Multi Serial Compound Device”. Click on “Finish” to complete found new hardware wizard.

Follow the same steps as explained for “High-Speed USB Multi Serial Compound Device” for the
second port installation . Select the option “Install the software automatically”……
“Continue Anyway”

The following wizard indicates that the OS has completed installing the software for the first serial
port. Continue the same process for installing the rest of the serial ports.

TRP-C08X device detection can be confirmed by checking the Device manager. Check for
“High-Speed USB Multi Serial Compound Device” under Universal Serial Bus Controllers and
“High-Speed USB Serial Port (Com X)” under the category Ports (COM & LPT)
