The FLEETPC-ARM-300 power input should be applied to the 3-pin DC-IN connector (CN3). Refer to Appendix C for DC-IN mating connector specification.   Refer to Appendix D for DC-IN connector specification. The input voltage can be in the range of DC 9V-36V. An Over-Voltage-Protection circuit   (optional function) is implemented to protect FLEETPC-ARM-300 from over voltage damage. CN3 Pin 2 (GND) (Ignition) CN3 Pin 3 CN3 Pin 1 (PWR) HDMI USB LAN1 LAN2 LAN3 LAN4 DC‐IN The pin 3 of DC-IN connector is a photo-coupled input (5KV isolation) dedicated for vehicle power ignition signal. The input is connected to FLEETPC-ARM-300 power on/off MCU. If pin 3 is not connected to the ignition switch, it has to be connected to HIGH (+12V) to ensure a simulated ignition signal is sent to FLEETPC-ARM-300. Refer to Appendix A for brief specification of the photo-coupler IC. The input power connection is suggested in the following diagrams:

directly and CN3 pin 3 is connected to ignition button. When FLEETPC-ARM-300 MCU detects car ignition on, it will turn on FLEETPC-ARM-300 system power. When car ignition signal is off, MCU will inform iMX6 to execute a Linux shutdown command (shutdown –h +xx, where xx is minute of delay, and xx can be configured in FLEETPC-ARM-300 device manager) and turn off system power. See “MCU- controlled power on/off” descriptions in this section.

This connection will make FLEETPC-ARM-300 always ON. Since CN3 pin3 is connected to high, MCU will always detect an ignition signal. Even software executes “shutdown –h now” or “echo 0 > /sys/class/leds/pwr_gpio/brightness” commands (see “MCU-controlled power on/off” descriptions in this section) to turn off system power, MCU will turn on power again in 5 seconds. Such connection is not suggested unless software developer knows when to turn   off FLEETPC-ARM-300 power. Power Connection 2 In‐car Power bus + ‐ Car Battery 3  2  1 CN3 FLEETPC

cigarette lighter socket. Since CN3 pin3 is connected to DC input, MCU will always detect an ignition signal as long as car power is on. Even software runs “shutdown –h now” or “echo 0 > /sys/class/leds/pwr_gpio/ brightness” commands (see “MCU-controlled power on/off” descriptions in this section) to turn off system power, MCU will turn on power again in 5 seconds. The FLEETPC-ARM-300 can only be turned off when the cigarette lighter socket power output is off. Power Connection 3 Cigarette lighter plug 3  2  1 CN3 FLEETPC ‐ARM‐ 300 Power Connection 4 – The FLEETPC-ARM-300 CN3 pin1/2/3 are connected to a +12V DC power adapter. Since CN3 pin3 is connected to DC input, MCU will always detect an ignition signal as long as DC adapter is on. Even software runs “shutdown –h now” or “echo 0 > /sys/class/leds/pwr_gpio/ brightness” commands (see “MCU-controlled power on/off” descriptions in this section) to turn off system power, MCU will turn on power again in 5 seconds. The FLEETPC-ARM-300 can only be turned off when the DC power adapter output is off. Power Connection 4 3  2  1 CN3 FLEETPC‐ARM‐300

The MCU-controlled power on/off allows software to turn off system power by issuing a command (via I2C channel 1, or GPIO) to the MCU (an 8-bit STM8S MCU). FLEETPC-ARM-300 provides applications (i2creboot and xsignal) in Linux for MCU’s action: i2creboot –m 0 // this command will wait until Linux finishes normal // system shutdown and then turn off system power. i2creboot –d xxx –m 1 // this command will immediately turn off system power and // then turn on system power after xxx seconds, where xxx // is 1 to 65535. This can be used for system reboot (cold start). echo 0 > /sys/class/leds/pwr_gpio/brightness // this Linux command uses GPIO to inform MCU to turn off system power immediately The xsignal is a background application persistently monitoring Linux RunLevel. When Linux executes “reboot” command and RunLevel becomes 6, xsignal will issue command “i2creboot -d 2 -m 1” to turn off power and turn on power after 2 seconds. When Linux executes “shutdown –h now” command, RunLevel becomes 0, xsignal will issue command “echo 0 > /sys/class/leds/pwr_gpio/brightness” to turn off power immediately. When the MCU turns off FLEETPC-ARM-300 system power, some components are still “ON” to monitor power input. These components include MCU, power regulars, power switches and over-voltage protection circuit (The grey blocks in below diagram). This means a minimum power will be dissipated by these components.
