UW-6 Power Bulkhead Connector Assembly Wiring
CB-Series Buoys without NexSens integrated electronics will ship with a solar tower and pass-through plate outfitted with a UW-6 power bulkhead connector (UW6-BULK) port. Information regarding the port pinout and different options for wiring power to user-supplied electronics is supplied below. For installation instructions, follow the guide here.
The diagram and table below show the pinout of the UW-BULK cable assembly.
|UW6-Bulk Pin #||Molex Wire Color¹||Flying Lead Wire Color²||Notes|
|3||Red||–||Solar Connector Jumps to Pin 6|
|6||Orange||Red||Solar Connector Jumps to Pin 3|
¹Molex connector is designed to interface with a NexSens CB-A01-2 or CB-A05-x battery harness. If this accessory was not ordered, connector can be cut off to wire to user-supplied components.
²The Red and Black flying lead wires are intended to supply power to user-supplied electronics.
Solar Charged Battery [most commonly used]
If power to the buoy electronics is to be maintained by a solar-charged battery and the buoy was not delivered with a CB-A05-x or CB-A01-2 battery harness, a solar regulator and 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 opened to manually disconnect the battery.
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.
