Aim PDM 32 - Other Internal Sensors and Channels; Math Channels Configuration

www.aim-sportline.com - PDM 32 User Guide 25
The status and labels associated to a every single digital input may be dependent upon the time
of activation (Time Dependent).
It is possible to enable an internal pull-up resistor, in case the digital input is closed to ground,
or an internal pull-down resistor, in case the input is closed to battery, as shown in the here
down image.
11.5 Other internal sensors and channels
The PDM offers other internal sensors, that may be used for activating some features or simply
for better understanding the vehicle behavior in data analysis:
- IMU 9 Axis: it features 3 axis accelerometer, 3 axis magnetometer, 3 axis gyros.
- Internal temperature sensor
- Brightness sensor (only with a display connected)
- SafeIgnition: it is ON when the PDM is activated by the IGN input. It is OFF when the
PDM is activated by CH_IN11 or CH_IN12
- POTotCurrent: it indicates the sum of all the currents drawn by the Power Outputs
- GPS information (only when the GPS module is connected)
11.6 Math channels configuration
The math channels are useful to create some channels depending upon the input data:
BIAS
CH1/(CH1 + CH2)
The BIAS computes which channel between two is
prevailing (typically used for suspensions or brakes)
Bias with threshold
CH1 / (CH1 + CH2)
As above, but computed only when the two channels exceed
a user configurable threshold
