fuses), should be added to the M-317 power cable. See Vehicle Battery Connection, on page 45.
WARNING!
Do not connect the terminal power to the ignition switch signal. This can cause uncontrolled
power cut offs, which may have a detrimental effect on the operating system. Instead, connect
the terminal power directly to the car battery and the ignition switch signal to the device’s
Automotive Input. When the ignition switch signal is powered off, use the shutdown function to
power off the terminal, ensuring that all files and sessions have first been closed.
Overview
The M-317 power comes directly from the vehicle's 12V/24V DC battery and provides intelligent
power management options that reduce drain on the vehicle’s battery. In addition, the M-317 also
enables the control of external peripheral power, backlight and power lines for internal modules.

Platform Power
Both internal and external devices can be turned on and off, as required.
Battery Voltage Input
The M-317’s power is connected through the main device 44 pin connector [pin 3 and 4 (+) and pin
1 and 2 (-)], directly to the vehicle’s battery or VLU (Vehicle Location Unit), to provide constant
power. The M-317’s nominal voltage supply, from the vehicle’s battery is 12v or 24v, and the
operating range is between 8v and 30v.

Super Capacitors
In order to prevent device storage drive corruption during an unpredictable power cut-off or voltage
cranking situation (during vehicle ignition for instance), the M-317 offers a super capacitor option for
short power backup.
Using this option, the device monitors the input-power voltage level and, if the power voltage drops
below 4.7VDC, the system closes the device’s backlight and disables the write access to the Flash
storage, USB storage and SD card memory. If the voltage level increases to a value above 3.8V DC
within 200 milliseconds, the backlight and storage access will be re-enabled and the device will
continue to perform as usual. If the voltage remains low for more than 200 milliseconds, the device
will perform a shutdown.
