Note that a small number of chart plotters and instrumental displays incorrectly process
the “no data available” value if there is more than one data source present on the network. This may
cause “flashing” of data on the display when it receives a “no data available” value after a valid value
from other source.
The Data transmission interval (6) setting allows changing of the interval of periodical (data transmitting)
messages with methods [2] or [3] and individually turning on/off message transmission with all three
methods. Intervals from 50 milliseconds (value 50) to 1 hour (value 3600000) are allowed, a value
of 0 turns off the transmission (but data can be received by request). “Restore default Interval” value
is also supported in method [3] (see Appendix C). In case of method [1], the user can only turn on
and off transmission of messages.
The Device sensor is calibrated at the factory, and wrong readings usually mean that the sensor requires
some cleaning (see chapter II) or is mounted improperly (see chapter III). Therefore, you can set an offset
(7) from -10.0 to +10.0 (Celsius, % RH) for the sensor readings to align with readings from other ship
equipment.
Installation description (8) are two text fields (see the next chapter), which can be filled in by installer
to specify the Device’s location or leave notes and contact data. Special strings starting with “YD:”
in the second field are used for Device programming in method [2].
Resetting of settings (9) returns a Device to the factory state.
The next two chapters describe the details of Device programming with methods [2] and [1].
Regarding method [3], please refer to your software manual and the NMEA 2000 Standard.
