General device configuration46 / 121 DLT-V72 Operating Instructions V2.509.3. Linux (optional)The configuration of the DLT-V72 with Linux with regard to radio networks, touchscreencalibration, etc. is described in the “Advantech Linux Manual”. Please contact ourTechnical Customer Support if required.9.4. USB Recovery StickThe optional recovery stick allows images to be backed up and restored onto the DLT-V72 when necessary(backup & recovery).The “USB Recovery Stick for ADLoG Terminals” user manual is available on ourwebsites.9.5. Automatic shut downFunctional descriptionThe DLT-V72 is equipped with an automatic shutdown module.If wired up accordingly, the DLT-V72 conveniently switches off together with the vehicle’s ignition.As disconnecting the power supply during operation can lead to data loss, the operating system needs to beshut down normally using the appropriate hardware and software installed on the system when the ignition isswitched off.The DLT-V72 is connected to the vehicle with three supply cables.DC+ and DC- are directly connected to the power supply of the vehicle, the connection is of course run throughfuses. The supply voltage connected is then linked to the DLT-V72’s ignition input via a switch, for example, thekey switch of the ignition (also with a fuse).SequenceWhen the vehicle ignition is turned on or the DLT-V72 button is pressed, the DLT-V72 checks itsinternal temperature and runs a test to confirm that the automatic shutdown function is working.If this check of the environmental conditions is successful, the DLT-V72 starts the operating system normally.Once these checks have been successfully completed, the DLT-V72 starts the operating system. Noenvironmental conditions (e.g. the internal temperature of the device or the state of the ignition input) arechecked for one minute during startup.After one minute, the DLT-V72’s internal temperature and the state of the ignition input are constantlymonitored.If the DLT-V72’s internal temperature reaches a critical level, a controlled shutdown of the operating system iscarried out. The computer will remain switched off until the temperature is once again within the permittedrange.If the ignition input is grounded or isolated during normal operation of the DLT-V72, the device will switch to adelayed shut-off state.The device will continue to operate normally in this state until the shut-off delay (e.g. 20 minutes) has elapsed.If the ignition is turned on again during this shut-off delay, the DLT-V72 will revert to a normal operational state.Once the shut-off delay (after run time) has elapsed, the operating system will shut down and the device willautomatically shut down (e.g. after one minute or a signal from the operating system).
