Bought this unit in 2017, haven’t used for a while and am trying to find manual/user guide with no luck. Can you assist? Question number one is what type of cord do I use to connect the laptop to the docking station? Thank you.


Thank you for contacting Plugable! I would be happy to provide additional information regarding our docking stations.

To set up your new UD-3900 dock, please follow the instructions provided in this link →

Regarding the USB 3.0 cable, your dock uses a USB-B to USB-A/C cable to connect to your laptop.

Hopefully this information was helpful, but please feel free to reach out if you have any follow-up questions or concerns.

Thank you!
