Seite drucken4 Starting the buoy
Before switching ON the buoy, unscrew the hatchcover from the hull, connect
the plug at the end of the main hatchcover connector cable between the hull
and the electronics unit as shown on the right and put the hatchcover back in
place. In case of under-pressure in the hull use the lifting hole to open the
hatchcover. Clean the o-ring groove beforehand. Take care that the rubber
sealing ring completely resides in the circular groove otherwise water will
enter the buoy. Fasten the 24 hexagon socket screws.
If you ordered an anti-spin triangle on your DWR-MKIII or WR-SG, you can
apply it now. If you expect difficulties in transporting the buoy with the
triangle in place, you may delay mounting it until the buoy is on board the
ship. Lift the triangle over the buoy and lower it on to the fender. Use two
screw bolts and one plate on all three touching sides to attach the triangle.
Place the HF/CAT4/LED flasher antenna on the port flange designated 'HF'.
Clean the groove beforehand. Take care that the rubber sealing ring completely
resides in the circular groove otherwise water will enter the buoy. Fasten the 6
hexagon socket screws.
Power the buoy by flicking the switch. Check if the buoy has started by
observing the flash lights. An even better way is to set up the receiving equipment and to
monitor the buoy output on your PC. Datawell has also developed the Buoy Tester application
(only for DWR-MKIII) to check whether all sensors on your buoy are working properly.
4.1 Buoy tester application
In order to troubleshoot your DWR-MKIII before it is deployed we have developed the Buoy
Tester application.
This application is free to download from the Datawell website:

5 Receiving antenna installation
Datawell supplies standard GP (ground-plane) antennas to receive all its models of wave buoys.
These antennas are able to withstand strong winds and are protected against corrosion. The user
should provide for an antenna mast with the same properties. For optimum reception the
antenna should overlook all surrounding buildings and have a direct view of the sea surface.
Consult local companies for lightning protection. Feed the antenna signal to the RX-C4 or RX-
D receiver through the high quality coax cable that is included in the GP antenna set. In less
demanding circumstances a portable antenna can be used, especially in combination with a
DWR-G4. The maximum range decreases to line of sight. It has a magnetic foot for easy
fixation.
6 RX-C4 and RX-D buoy receiver
The RX-C4 and RX-D receive the following buoys: DWR-MkIII, DWR-G and WR-SG.
Connect the antenna coax cable to the connector on the back panel. Once you have applied
power, the receiver will inform you of the buoy readings on the LCD display.
Datawell will tune the receiver to the transmitting frequency of the buoy.
