4.2.4 Self-Diagnosis
After ten speed measurements, the self-diagnosis is performed. The self-diagnosis checks:
x
Transmitter
x
Receiver
x
Internal signal data paths
x
ADC (Analogue to Digital Converter)
x
High speed (LVDS) interface integrity
x
Transducer
x
External noise
x
Input signal balance
If a detected failure persists for at least 14 diagnosis cycles, a diagnostic code will be sent as an
NMEA telegram with the proprietary sentence PSALW. Also the ALERT LED at the WATER
TRACK U board will be turned on.
4.3 Menu system
The WATER TRACK U has an internal menu system that can be accessed via a serial interface
connected to a remote display such as the NWW-82 Speed log Master Display.
The information is presented as two lines with 16 characters. All WATER TRACK U settings,
calibration, etc., can be changed through the menu system.
The settings are stored in non-volatile memory and will therefore also be active after a reboot
or power shut-down.
4.3.1 Accessing the Menu system
Here follows a short guide to access the menu system in WATER TRACK U via an NWW-82
Speed Log Master Display. (For a detailed description of the NWW-82 menu system, see
Section 7
)
.
4.3.2 Reaching NWW-82 Menu Mode
The Mode window of the NWW-82 Display can be set to Menu Mode, which is used for
internal settings of the display and can be used to connect to a remote unit such as WATER
TRACK U.
The Menu Mode is reached by pressing the
Mode
button for minimum 5 seconds. The Mode
Window will show the text “PRESS ENTER FOR MENU”. Then press the
Enter
(4
th
button
from left) within 5 seconds.
The Mode Window will now show the start menu in the NWW-82. The six buttons under the
Mode Window have now got alternative functions. The alternative functions are lit in red text
below relevant button.
The buttons now have the following functions:
