Apply Power to the X2-CB

The X2-CB has an innovative power design that allows for simple connectivity and interfacing with NexSens CB-Series buoys.


Power Jumper

CB-Series solar towers have a special UW-6 plug with a jumper built in that completes the circuit for the battery to supply power to the X2-CB data logger. The X2-CB will not receive power unless the solar panel is connected to the COM/SOLAR port. Alternatively, a UW-JUMPER plug may be connected to the COM/SOLAR port to complete the connection.

All standard CB-Series buoys meet and exceed the X2-CB required specifications.


Power Accessories

Please visit the accessories tab on the X2-CB product page to purchase power accessories.


Connector Wiring

Solar power is supplied to the CB-Series battery pack via the UW-6 Receptacle port. The port also acts as a power switch between the battery and the data logger. This allows users to easily disconnect power when the logger is not in use.The below table and diagram show the proper connections for the X2-CB’s UW-6R port.
