DL-V3 User Manual Rev 3 41
The data logging mechanism is designed to be robust and to endure power interruptions (and similar
disruptive events) with minimum loss of data. In this situation, allow for your data to be possibly
reduced by several seconds up to a maximum of five minutes. When possible, error messages are
generated to identify problems as they arise. Refer also to the RXSTATUS log in the OEMV Family
Firmware Reference Manual.
Card Choice
You have the flexibility of choosing the CF card with the storage capacity that is the most appropriate
for your needs, based on the selected logging rate. This is discussed in greater detail in Section 3.4,
Using the DL-V3 starting on Page 51.
Take for example the case where you have to format and use a CF card (the DL-V3 comes with a 64
MB card but up to a 2 GB card is compatible):
At least 1% of free space must be available on the CF card to open a log file. On a 64 MB
disk, there is a 0.64 MB allowance for the file table.
Using CDU to Format the CF Card
1. Establish a physical communication connection between the DL-V3 and the PC/laptop. Either
connect COM1 on the back of the DL-V3 to a DB-9serial port on the PC/laptop or connect the
USB port on the front of the DL-V3 to a USB port on the PC/laptop.
2. Ensure the CF card is in its DL-V3 slot.
3. Launch CDU and open the DL-V3 configuration, refer to CDU’s on-line Help for details.
4. Select DL Explorer from the Tools menu in CDU. The DL Explorer window opens.
5. Click on the CF Status button in the DL Explorer Window:
6. Click on the Format button to format the CF card for use with the DL-V3. The format sequence
erases all data previously stored on the disk. This operation is not reversible and a warning
message is also shown:
The Format process closes all log files first. If a file transfer is in progress, it is stopped and then
the disk is formatted. The logs being logged to file are still present in the log list. The following
command can be entered in CDU’s Console window to remove them:
