For step-by-step installation instructions, insert the CD in your computer and click the “Install USB Driver”
link on the Welcome screen. The software will install the appropriate driver that is compatible with your
computer’s operating system.
When the software is fully installed, the adapter can be connected to the computer and used to connect to the
MC-III via MC-III software (Tools/Select COM Port).
