If you see a message like this, your OT-2 is having trouble communicating with the pipette that you just attached.

First, try unplugging the white connector tab from the pipette and re-inserting it. Ensure that the connector is plugged in securely. Then, click Have robot check connection again.

If the pipette still cannot be detected, there may be a problem with the pipette, or with one of the OT-2's cables. To narrow things down:

  1. See if the pipette can be detected in the other mount, leaving the original mount empty.

  2. See if a different pipette can be detected in the same mount.

And contact Opentrons Support for assistance.
