the U3 Launchpad and click on Settings, then select U3 Launchpad Settings and click

6. Create a directory in the current working directory for data logging: Type [FSMKDIR]
followed by a directory name. (i.e.
[FSMKDIR] “Pt_Conception”, Refer to the [FSMKDIR]
command for details on creating directories.) Repeat to create multiple directories for data
logging.
The directories will be stored in the “datalog” folder (see Figure 6).
7. Type [LOGFILE]A:, START
8. Click the Send button to begin logging the scheduled messages into the specified directory
(messages are logged in the *.dat format; see Notes below).
9. Type any of the following on the Input Terminal window, as necessary (updates can be a
little slow; only issue the command once and allow 30 seconds for a response):

[LOGFILE]A:
– displays the current file logging status for the internal memory device

[LOGIFLE]A:,pause – stops data logging on drive A until a resume command is issued

[LOGFILE]A:,resume – resumes data logging on drive A

[LOGFILE]A:,stop – stops data logging on drive A

[LOGFILE] – displays the current file logging status for drives A and B, including
READY, RUNNING, STOPPED, or PAUSED

When the status is RUNNING or PAUSED, the logged bytes are displayed.
[LOGFILE]A: RUNNING 5245989 BYTES LOGGED; B: STOPPED

After power cycle, file logging is in Stopped status. If DC power is removed from the
receiver power input port prior to turning off the front panel switch, there is a risk of
corrupting and losing the stored data. Always stop data logging before removing
power. Similarly, there is a risk of corrupting and losing the stored data if DC power
is removed from the receiver power input port while transferring data from the
receiver to a PC.

Each time data logging is restarted, a new log file is created (see Figure 8). The log
files are created in a datalog_YYYY_MM_DD_HH_MM.dat format.
