life bef ore charging is required. The system will be more
sensitive to bad communication conditions due to the slow data
update.
System configuration
Sensor configuration: The sensor must be configured with a
unique sensor number. Select update rate and channel number
according to the sensor’s configuration. Write down this
configuration for future reference.
Status & Receiver: The Interference filter must be switched on.
Set it to level 9 if you have noise problems from other
hydroacoustic sources. Note t hat with the filter on, it will
influence the signal spectrum shown in the Status display.
Catch/Bottom sensor filter: Switch this f ilter off. Set it to
Light or Heavy only if you experience excessive noise.
Mounting
Location: Place the sensor where you
wish to monitor bottom contact. This
is normally in the center of the net.
Seize the attachment ring (A) for the
stay underneath the net, then put two
carabine hooks inside the footrope
forming a bridle of 15 to 20 cm
securely holding the sensor in a stable
position.
Penetration ring: Place the
penetration ring (B) for the detection
wire approximately 30 cm rear of the
footrope. Before final seizing, mount
the sensor to the carabine hooks and
check that the detection wire (E)
passes trough the center of the
penetration ring (B). Remove any net
on the i nside of the penetration ring.
