Speed sensor
The speed sensor may be a separate
unit, or it may be integrated with the
echo sounder transducer. You can also
connect to external water speed
sensors using the NMEA interface.
A typical setup page is shown. For
more detailed information about the
parameters, refer to the operator
manual.
1 Ensure that the sensor is connected to the PI54.
- If an echo sounder transducer with a buit-in speed
sensor is, it must be connected to the Echo1 socket.
- If you use a separate speed sensor it must be connected
to Echo1.
- If you wish to use speed information from an external
source, you must connect this external sensor to the
NMEA1 or NMEA2 sockets.
2 Power up the PI54. Once up and running, press the
MENU button to open the main menu.
3 Press 4 to open the Setup menu, and 3 to open the
Interface setup dialogue. Allow the PI54 some time to
scan through the available i nputs.
4 Press the PAGE+ button four times to open the Water
dialogue.
5 Observe that the PI54 has detected the water speed sensor.
- The setting Source will show the name or identification
of the external system. Typically, the setting will read:
Source (one available).
- The name, identifiaction and/or input connector is
shown on the next line.
- Note that if more than one depth sensors are detected,
all will be listed.
6 If more than one speed sensors are listed, move the cursor
to the system you wish to use, and press the ENT button
to select it.
7 If only one sensor is shown, it is automatically selected by
the PI54.
8 Press the ENT key to acknowledge the setting and exit.
If Source is set to None, the most likely reason is that you have
a problem with the wiring.
