1.6 Theory of Operation
The VDR100 records every frame of NMEA 2000
®
network activity onto the attached USB
flash drive.
1.6.1 General Concepts
1.6.1.1 Data Recording
The VDR100 records every single frame of data on the NMEA 2000
®
network.
In order to perform performance analysis, the time at which each event occurs must be
accurately recorded. To this end, there must be a source of time information on the NMEA
2000
®
network, for example, a Maretron GPS or equivalent.
WARNING
At least one device transmitting valid data in the NMEA 2000
®
System Time
(126992) message, for example, a GPS receiver, must be operating on the
network in order for the VDR100 and the
N2KExtractor
®
program to be able to
correlate the data with the time when it was present on the network.
The VDR100 records data to a circular buffer on the USB flash drive. When the USB flash
drive becomes near full, the oldest data on the device is deleted in order to make room for
newer data.
