UW6-Bulk Pinout

CB-Series Buoys without NexSens integrated electronics will ship with a solar tower and pass-through plate outfitted with a UW6-Bulk port. Information regarding the port pinout and different options for wiring power to user electronics is supplied below.

¹The Molex connector is designed to interface with a NexSens CB-A01-2 or CB-A05-x  battery and solar regulator harness. If this accessory was not ordered for the buoy, users can cut-off this connector to wire to locally-sourced components.

²The Red and Black flying lead wires are intended to supply power to user-electronics.

Wiring Options


Solar Charged Battery [most common use]

If power to the buoy electronics is to be maintained by a solar-charged battery and the user did not purchase a CB-A05-x or CB-A01-2 battery harness, a solar regulator and 12V SLA battery must be sourced locally.

The internal jumper inside the solar panel connector disconnects battery power from on-board electronics when the solar panel plug is removed from the UW6-Bulk port. This simplifies system storage as the data well does not need to be accessed to manually disconnect the battery.

Battery ONLY

If solar charging is not required for the application, a user may source a standalone battery to supply power to on-board electronics. The following wiring will direct battery power to the Red and Black flying lead wires of the UW6-Bulk
