Sensor configuration
On delivery, all depth sensors are configured in Channel 16
(300 m), Channel 12 (600 m) or Channel 10 (1000 m) and with
Fast update rate. It is not possible t o change the update rate
setting. If you use more than one sensor, you must set them up
to operate in different channels.
Note: The sensor and the PI54 system setup must correspond,
otherwise the communication will not work.
To change the sensor setup (channel selection), use the PI
Configurator utility.
The sensor update rate controls how often the depth is
measured, and the data transmitted to the vessel. To be able to
monitor critical depth information and avoid damage to the
purse seine or the trawl, the depth sensor will only operate on
Fast update rate.
System configuration
Sensor configuration: The sensor must be configured with a
unique sensor number. Select channel number according to the
sensor’s configuration. Write down the 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.
Sensor filter: Switch this filter to Light. Set it to Heavy only if
you experience excessive noise. Position Off will provide raw
data and fastest possible response.
