LabQuest 2 has a few types of connectors. Motion Detectors and other digital sensors connect to the digital ports (DIG 1 and DIG 2). To access the ports, peel back the rubber cover on the long edge of the LabQuest.

The analog ports (CH 1, CH 2, and CH 3) located on the short end of the LabQuest are used to connect most sensors.
