You may monitor the available space on a USB flash drive using N2KView
®
software or a
Maretron DSM150/DSM250 display. If you wish to keep all recorded data on the USB flash
drive, simply remove the USB flash drive from the VDR100 and replace it with an empty USB
flash drive before the first USB flash drive becomes full.
1.6.1.2 Flash File System
The USB flash drive will be re-formatted the first time it is used in the VDR100. This is done in
order to ensure filesystem integrity of the USB flash drive in the cases of removal of the device
from the VDR100 and also in cases of power removal from the VDR100,
WARNING
When you plug a new USB flash drive (one which has never been used before
in a VDR100) into the VDR100, ALL DATA ON THE MEMORY DRIVE WILL
BE DESTROYED. If your USB flash drive has data you wish to save, please
archive it before plugging the USB flash drive into the VDR100.
The filesystem that is created on the USB flash drive is not compatible with Microsoft
Windows. Drivers for the filesystem used by the VDR100 are included with the Maretron
N2KExtractor
®
software.
1.6.2 Operating States
The VDR100 has several different operating states, which can be monitored by observing the
USB LED on the unit, or by monitoring the VDR Status message transmitted by the VDR100
using a DSM150, DSM250, or N2KView
®
software.
