Simrad PI54

850-165186 / Rev.B
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. 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 sensor reads and
reports the current depth. Three settings are available. Note that
a faster update rate will decrease the battery life.
• Fast (~4,5 sec): Recommended for purse seine or trawl,
allows immediate update of critical depth information, and
helps to avoid damage to the purse seine or trawl.
• Normal (~14 sec): Recommended for trawl and normal
fishing.
• Slow (~34 sec): Recommended if maximum operational
battery life before 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 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.
