Initiating a Recording with the IQ3 Drag Dash data logger
Anytime power is applied to your system the data logger is ready to record data from the
various sensors connected to the system. When the recording process actually begins and how
much data is recorded is determined by how you program the setup features in your data
logger. The staff at RacePak will have setup your data logger to start recording via pushbutton
by pressing and holding either of the pushbuttons until REC appears on the dash display. The
warning lights will typically flash at least 3 times before REC appears. If you wish to modify how
the data is recorded read the following information.
The start of the recording can be programmed to occur by different methods. These are;
Start Recording Manually on Operator Input (default)
In this mode a momentary push button switch is connected to one of the inputs on the data logger. Each
time power is applied to the data logger; the logger monitors the input, and will begin recording only
when either of the included pushbuttons is held down until the dash displays REC on its screen. Once the
recording is started, it will continue until the maximum record time is reached, or the power is turned off.
Start Recording Automatically when threshold is exceeded.
In this mode the logger is programmed to begin recording only after one of the monitored data channels
exceeds a preset threshold. For instance, the logger can be programmed to begin recording once a
threshold has been reached, for example once the Engine RPM exceeds 3000 rpm. Once the recording is
started, it will continue until the maximum record time is reached, the power is turned off, or the RPM
goes below the Stop Record threshold for more than 30 seconds.
When setting the start record parameters, please keep in mind that it can take up to 1-2
seconds from the time a new recording is initiated, and the time data actually begins to be
recorded. This time is required for the IQ3 Drag Dash data logger to initialize a new recording
and varies depending on the number of V-Net channels installed in your system and the
number of data files on the SD memory card.
Recording Data
After you have programmed the recording parameters as described above, you are ready to
record run data using your new data logger. To record data simply turn on power to your
system. The recording will begin any time the conditions as programmed above are met. The
status of the recorder in the IQ3 Drag Dash data logger will flash REC on the screen while
recording data. The recording will end when the Max Number of Seconds to Record is reached,
the Start Record Channel data goes below the Stop Record Value for more than set period of
seconds, or the power to the data logger is turned off.
If you have selected to automatically start the recording when a data channel exceeds a
programmed threshold, be sure the data channel is functioning properly or the recording will
not start. In addition, if you are trying to take a warm up recording in the pits, be sure the data
channel exceeds the start threshold or no recording will be taken.
