Note 1:
Unlike the programming method described in the previous chapter, this method does
not allow setting the interval for messages with periodic transmission. This method
allows turning on and off message transmission only. When transmission is turned on,
the interval specified in NMEA 2000 Standard for this message is applied (see Appendix C).
1st bit (least significant) corresponds to PGN 130311 “Environmental Parameters”,
2nd to PGN 130312 “Temperature”, 3rd to PGN 130313 “Humidity”, and 4th to PGN
130316 “Temperature, Extended Range”. Factory setting have all these bits set (value 15,
1111 binary). Increasing of the value over 15 causes it to reset to 0 (transmission
of all periodic messages is off) and the next increase will turn on the transmission
of PGN 130311 (setting value of 0001 binary).
Note 2:
1st bit (least significant) corresponds to humidity, 2nd bit to air temperature and
3rd to dew point temperature. Factory setting has all bits set (value 7, 111 binary).
Increasing of the value over 7 causes it to reset to 0 (transmission off for all data types)
and next the increase turns on transmission of humidity (setting value 001 binary).
STEP 4. Saving the settings in the non-volatile memory
Without turning the Device power off, change the chart datum setting on the plotter to “WGS 1984”,
or magnetic variation setting to 27°W. The Device will save the settings in the non-volatile memory,
produce three confirming signals, and return to normal operation mode. If you do not save the settings
into the non-volatile memory, they will be kept only until the power is turned off (see STEP 2). Do not forget
to return the initial chart plotter settings after programming.
