Receiver setup
These settings are used to establish the communication
parameters between the PI54 and the sensors.
To access the parameters, press the MENU button to access the
Setup menu (4). Then, select Receiver setup (6). You need to
acknowledge the access with the ENT button before the
dialogue is displayed.
The Receiver setup parameters have a major influence on the
PI54 performance. The default settings are those we have found
to be the best for general use, but for individual installations
optimized settings may enhance the performance.
Interference filter: When this filter is active it will remove
interference (noise and false echoes) from other echo sounders
and sonars in the the vincinity of your own vessel. It may not
remove all interference, but in most cases you will find this
filter to be very efficient. If you suffer from poor range
performance, and the spectrum on the Status Display is nearly
flat, this f ilter may also prove useful. A normal sensor will then
show up with a narrow peak at its dedicated frequency. This
filter is by default switched on and set to level 9, and will tend
to prioritize stronger signals.
Interference filter level: Use this setting to control the strength
of the Interference filter. 9 is the default value and the heaviest
filtering. Selecting 0 will hardly have any effect, and is really
equivalent with the f ilter switched off.
