NexSens CB-450 Data Buoy User manual

CB-450 Data Buoy –Quick Start Guide
The NexSens CB-450 Data Buoy is designed for deployment in lakes, rivers,
coastal waters, harbors, estuaries and other freshwater or marine
environments. The floating platform supports both topside and subsurface
environmental monitoring sensors including weather stations, wave sensors,
thermistor strings, multi-parameter sondes, and other monitoring
instruments.
What’s Included:
•(1) Buoy hull with data well
•(3) 10W Solar panels (mounted to tower)
•(1) Data well lid
•(3) Top-side lifting eyes
•(3) Bottom-side mooring eyes
•(1) Instrument cage

CB-450 Step-by-Step Assembly
Attach the cage to the buoy frame:
1 Attach the cage to buoy frame using the ¾” bolt, lock washer
and castle nut.
2 Tighten firmly with 1-1/8” wrenches or large crescent wrenches.
Be sure to flatten the lock washer and lineup the hole in the bolt
with the notches in the castle nut.
3 Place the cotter pin through the hole in the bolt, and bend the
long leg of the pin to prevent the nut from coming loose.

Understanding the data well with NexSens data loggers
The data well is a waterproof canister located in the center of the buoy hull. Batteries are
secured at the bottom and a data logger is mounted to the underside of the lid. The data well
lid provides convenient connection ports for sensors, an antenna, solar charging, and a vent.

Understanding the NexSens data logger ports
Ports include:
•(5) sensor input ports
P0A - 12V switch power, shared RS-232 with port P0B, SDI-12, RS485
P0B - 12V switch power, shared RS-232 with port P0A, SDI-12, RS485
P1A - 12V switch power, shared RS-232 with port P1B, SDI-12, RS485
P1B - 12V switch power, shared RS-232 with port P1A, SDI-12, RS485
P2 - 12V switch power, unique RS-232 port, SDI-12, RS485
•(1) Solar charging port
•(1) Gortex vent for relief of battery outgassing pressure. In heavy wave conditions this
vent can be plumbed with tubing to the top of the tower.
•Antenna port
Note: Sharing RS-232 ports means that only one non-addressable device can be
connected at a time. RS-485 and SDI-12 ports are shared throughout the bus.
Note: To connect analog sensors (i.e. 4-20mA, 0-2.5V) use the mV-RS485 adaptor
