VII. Recording of Diagnostics Data
The Device allows all processing data to be recorded to the MicroSD card for the purpose of diagnostics
and configuration.
Recording of diagnostics data is not a normal operation mode. Recording to the MicroSD card
can cause delays in messages processing and some NMEA 2000 messages may be skipped.
High-speed MicroSD cards from proven manufacturers can reduce the impact.
Create a file called YDNG.TXT with the following lines included:
DIAGNOSTICS=60
LOG_FORMAT=TEXT
Where 60 is a duration of diagnostics recording in seconds (1 - 3600 is allowed), one minute in the example
above. LOG_FORMAT can have TEXT or BINARY values. If this parameter is wrong or omitted, TEXT
is used.
Note that the given settings are not saved in the non-volatile memory and will no longer apply after the card
is removed or when the NMEA 2000 network is powered off or if the recording finishes after a specified time.
Insert the MicroSD card into the Device. The Device will produce a 1-second green LED flash that indicates
that recording has started.
Do not eject the card during recording, or the recording will be lost and the file system of the MicroSD card
may be corrupted. The Device will inform you with a 1-second red flash of the LED that recording is finished.
After this, the memory card can be safely removed from the Device.
