UW-6 Power Bulkhead Connector Assembly Wiring
CB-Series Buoys supplied with a CB-PTL Pass-Through Lid for integration of user-supplied electronics include a UW-6 power bulkhead connector (UW6-BULK) port on the lid. The UW6-BULK connects to the solar tower on the outside of the buoy and has bare wires with Molex connector on the inside of the data well. 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.
