This simply resets the orientation to the factory preset. The preset for an internal GF module is
assumed that the PDR is flat with the LCD/Keypad facing upwards and the button/led/battery
door is facing the rear of the vehicle.
GFORCE RECORD TRIGGER
Gforce Record Trigger is used to tell the PDR100 to record when it senses a predetermined
motion setting. In other words, you can set it to record when the vehicle is moving. The top line
will give you status such as GFORCE TRIGGER IS ON. The next line is a menu option that with
a select key press, will toggle through your choices. You can TURN THRESHOLD ON, TURN
DIFFERENCES ON and TURN OFF GFORCE TRIGGERING.
THRESHOLD
Threshold is used to indicate a minimum Gforce reading. Use THRESHOLD only if your Gforce
module is calibrated and reading zero or close to zero at rest.
DIFFERENCES
Differences is a safer method in that if you did not calibrate the Gforce module, the PDR100 will
not look for an absolute Gforce number, but will look for a difference. The unit can read 0.78 G at
rest, but will not trigger until you reach a difference from that number (or any number it hits).
SENSITIVITY
Here you can simply set what kind of Gforces will trigger the recording. If the intent is to record
ANYTIME the vehicle is moving, we recommend setting the unit to 0.19Gs. But other numbers
are available. If you only want to record extreme driving from someone that borrowed the car, or
accident avoidance, than setting the unit to 0.50 or 0.75G makes sense. You may wish to
experiment here.
DELAY
Set the PDR to keep recording AFTER it no does not receive a trigger command from the GForce
settings. In other words, if you set the PDR to start recording at 0.13Gs, as soon as it hits 0.13Gs
or higher, it will start recording. As soon as it no longer senses 0.13Gs or higher, the delay
countdown will start. At the end of the countdown, if it has not been triggered again, it will stop
recording and go into pause mode, waiting for the next trigger. You can set the delay at
10,20,60,120,300,and 600 seconds. What this means is, if you want to only record an autocross
run, set the trigger to 0.5Gs and then the delay to 10 seconds. A normal drive from the paddock
to the starting line will not trigger the recording, and the recording should stop 10 seconds after
your run is over. Or if you want to record a standing start or launch, make sure you are recording
when you come to a stop (hit the brakes to trigger if needed). Then with the delay set to 300
seconds or so, the unit will keep recording for 5 minutes.
Note we are looking to add “pre-triggered recording” to the PDR100 at some point, so keep
updated on the features.
AUTO ON and AUTO RECORD
To sum up, you can set up the PDR100 to automatically record anytime the vehicle is moving.
We recommend the use of the Supercap Power Supply option for this feature. The PDR100 can
be set up to automatically power up when the vehicle is powered. Simply hardwire the switched
accessory 12V supply to the PDR100 terminal block. Make sure the AUTO ON switch is
properly set.
AUTO ON SWITCH
In all newer PDRs, there is a small red block switch just inside the battery door (below the
power/record switch). If the white switch lever is pushed toward the middle of the PDR100, then
it is set to not come on automatically. If it is pushed to the outside, then the unit should power up
anytime it senses external power being applied.
