850-165186 / Rev.B
Sensor configuration
On delivery, all Height sensors are configured in Channel 14
and with Fast update r ate.
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 sensor reads and
reports the height. T hree settings are available. Note that a faster
update rate will decrease the battery life.
• Fast (~5,5 sec): Recommended for new trawl or changes in
rigging to monitor any instabilities or unexpected changes.
This mode provides the shortest battery life before charging.
• Normal (~14 sec): Recommended for well known trawl
behavior with stable situations. Use this setting during
normal conditions.
• Slow (~34 sec): Recommended to monitoring a stable
situation over time. The system will be more sensitive to bad
communication conditions due to the slow data update. This
mode provides longest operational battery life before
charging.
System configuration
Sensor configuration: The sensor must be configured with a
unique sensor number. Select channel number and update rate
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.
