Page 8: Chapter 3 - Getting Started
CHAPTER 3 – GETTING STARTED Before deploying a CB-400 data buoy , it is very important for the user to become familiar with the hardware connections and operation of the system with iChart software. To begin, lay out the buoy, sensors, data logger, and other components that make up the CB-400 system. -
Page 9: Gathering Sample Data
Connect all sensors, power the system, and gather sets of sample data with iChart software. Refer to the SDL500 and iChart manuals for additional information on setup and testing of the software, data loggers and sensors. Systems may also ship with project-specific startup documentation provided by NexSens Customer Support. CB-400 Data Buoy User’s Manual... - Page 10 NexSens Technology, Inc.

Page 11: Chapter 4 - Buoy Setup
February 19, 2013 CHAPTER 4 – BUOY SETUP This section contains detailed instructions on the physical setup of a CB-400 buoy system. Directions are included for a complete CB-400S package with solar panels and RBP500 battery pack. For standard CB- 400 systems without solar charging, the process is the same, but all sensor connections are made directly to the SDL500 data logger. -

Figure 4-8: Sensor Connected to RBP500 Port P0 Accessories Deployment pipes, instrument cages and ballast weights can be added to CB-400 buoy systems. Deployment pipes and instrument cages provide options for secure mounting of sensors, and ballast weights can help to balance the buoy and prevent overturning. -
Page 16: Instrument Cage
February 19, 2013 4.2.2 Instrument Cage The CB-400 buoy allows an instrument cage to be installed on the bottom. Sensors can be securely attached to the instrument cage. To install the cage, first remove the 1-3/4”-10 x 4” bolt, 1-3/4” lock washer and 1-3/4”-10 nut from the buoy frame. - Page 17 On the bottom end of the rod, tighten a 1-3/4” eye nut with a 1-3/4” lock washer. Tighten the top end of the rod securely to the buoy frame or instrument cage with a 1-3/4”-10 nut and 1-3/4” lock washer. Weld the connections to prevent loosening in rough water.

NexSens does not endorse any particular mooring strategy for any application unless the end user performs a thorough review of the site conditions with the NexSens engineering team. -
Page 19: Two-Point And Three-Point Moorings
Stainless steel bow shackles are used to connect the various mooring components (mooring lines, marker buoys, chains and anchors) together and to the CB-400 buoy. Bow shackles must be properly connected and secured to prevent hardware from loosening and becoming detached over time in rough water conditions. - Page 20 Figure 5-4: Cable Tie Installed on Bow Shackle A 1/2” bow shackle is used to connect mooring lines to the CB-400 buoy eye nuts and to 1/2” bottom chains. Larger, 5/8” bow shackles are required for connection of marker buoys and anchors.
