Under 'Communication', select 'Port Setting'. OR select the USB icon. Either select the COM Port manually using the arrows or click the box to use USB (The default setting is USB and should be kept on USB unless issues arise):

Important: If the VCM-TR1 is not powered by the motorcycle (VCM-TR4/TR3 and Maximus will be powered by the USB connection), then the correct COM Port will not appear (indicated by an illuminated LED).
To rectify, press 'Cancel' and power the VCM-TR1 by turning on the ignition switch and making sure the engine stop/run switch is in the RUN position. Once the LED light is on, the hardware is on, select 'Communication' and 'Port Setting' again to select the correct COM Port. The TR4/TR3 VCM will receive power from either the computer or the motorcycle, as long as either is connected via cables.

Test for connection by selecting testing the VCM (see animation below).

If connection fails, see the next step for trouble-shooting COM port connection issues.
