The Auto Shut Down feature allows battery-capable PDRs to act like SuperCap ones. You can
make an internal-battery-powered PDR automatically shut off in two ways: (1) IF NOT
RECORDING makes the PDR shut down after it has not recorded video for the desired length of
time, or (2) IF NO EXT POWER makes the PDR shut down after it goes without external power
for the preset length of time. The Ext Power feature works similarly to a SuperCap setup.
RECORD SWITCH STYLE
This feature is only used with some data acquisition systems and should not be used on a
stand-alone PDR.
This changes the record button to only record when the button is HELD
DOWN, as some data acquisition and security systems trigger recording in this way.
GFORCE RECORD TRIGGER
See GFORCE section below.
GFORCE
The GF module is available as an option from your dealer or ChaseCam. The module is sold as
either an internal or external device. The internal module needs to be factory installed. If your unit
does not have the GForce module, you will not see the menu option. The GForce module will
overlay the GForce readings and scaled moving bar graphs onto the video, in real time.
Technical data- The GForce module is 3 axis and user set. This means that you can place the
module or recorder in any orientation. The GForce is sampled once per video frame, or 30 times
a second for NTSC and 25 times a second for PAL. The horizontal bar graph is scalable (up to
3G). Vertical bar graph is red for braking (negative G), and green for acceleration (positive G).
CLEAR BACKGROUND – SHOW BLACK BACKGROUND
This will put the text and bars directly on the video. Less obtrusive, but might not work as well if
the background is very light. You may get better results in that case, by toggling this to SHOW
BLACK BACKGROUND which will place the text and GF bars on a black background.
PUT AT TOP – PUT AT BOTTOM
Moves the horizontal text and bars to either the top or bottom of the screen. The left side vertical
bar is not movable.
TURN GFORCE TEXT ON - OFF
This setting allows you to turn off the text that displays the GF readings (such as 1.04) and only
display the bar graphs.
SCALE
You can set the scale to match the vehicle. The most common setting for most race cars would
be 2. We recommend using 1 for street use. A setting of 3 would be used for more extreme racing
cars or vehicles. If the GF readings exceed the scale, it will just mean that the bar graph will be at
the end of what it can display. The text will still reflect the actual measurements (up to 4G).
SET ORIENTATION
This will allow you to calibrate the GF module. Very simply, with the module or recorder securely
in the position you intend to use it, position the vehicle on a level surface with enough room to
complete the calibration. Press SELECT when parked. Wait one second and then accelerate
straight forward for a short distance and then fully brake to a complete stop. You do not need to
use excessive speed or braking forces. You are only instructing the module to learn where it is
located relative to directions. Press SELECT again. The PDR LCD will display if it was successful
or not. Press SELECT again to see a report screen.
