13 REMOTE STORAGE MODULE (OPTIONAL) AND
USB MEMORY STICK
The primary devices used to retrieve recorded data from the internal hard drive of the DMM is
either the USB Memory Stick or the optional RSM. Copying data to the USB Memory Stick or
RSM does not affect the normal recording by the VDR-100G3.
NOTE: The USB memory stick must be removed and the optional RSM, if
purchased, must be connected before data can be saved to the RSM.
The OAU initiates copying of data to the USB Memory Stick (or RSM) for retrieval and analysis.
Refer to Section 11.13 - Copying Data to USB Memory Stick (or Optional RSM).
Independent of copying data to the USB Memory Stick (or RSM), the VDR-100G3 automatically
records the most recent 4 GB of recorded data to the USB Memory Stick. The OAU displays the
status of the USB Memory Stick device during recording. See Table 11.1 – OAU Status of USB
Memory Stick (or optional RSM).
Unlike the FRM, which contains only data required by IMO regulations, the USB Memory Stick
may contain a much larger and more detailed data set. This data set includes all AIS/NMEA,
audio and video data collected by the VDR-100G3.
During normal operation, the DMM will store the most recent 4 GB of collected data to the USB
Memory Stick. During this time of recording, the OAU status for the USB Memory Stick will
display “USB: REC”. In typical installations this gives approximately 24-28 hours of recording
time. When the USB Memory Stick becomes full, the oldest data contained on it is overwritten
with the new data. This process continues until, via the OAU, an operator either ejects the USB
Memory Stick from the VDR, or selects to copy a data set to it.
Warning: The following situations will results in all data being deleted from the
USB Memory Stick:
1. When the USB Memory Stick is ejected and physically removed from the
system, and then re-connected, the VDR will erase all the data on the
USB Memory Stick and begin recording data to it again; When data from
the USB Memory Stick is downloaded or copied, if the drive is NOT
ejected and physically removed within 1 hour after the download is
complete, then the VDR will erase all data on the USB Memory Stick and
begin recording data to it again;
2. When the USB Memory Stick is unplugged from the system, without first
ejecting it, and then it is re-connected, then the VDR will erase all data
on the USB Memory Stick and begin recording data to it again;
3. When attempting to download or copy a data set to the USB Memory
Stick, if there is insufficient memory, then the VDR will erase all data on
the USB Memory Stick in an attempt to free enough memory for the
download to succeed.
NOTE! The configuration <Vdr-cfg.txt> and parameters <vdrparams.ini> files,
which may be used to correctly interpret playback information, are stored and
located in the root directory of the removable drive.
