This is implemented as a windows service that detects any power event (Suspend, Hibernate, Reboot, Shutdown) and can send a proper response to the control circuit (Heartbeat or Kill). The trigger is also controlled via Ignition Power so that the amp will shut off when the car`s ignition is turned off regardless of the status of the carputer or the

override switch. The communication between the device and computer happens via USB and emulated Serial protocol. When the delay is changed on the device, a new value is sent to the computer so that the service timer can adjust it`s heartbeat rate accordingly. By default, the service will send 2 heartbeats per delay value but that can be changed in the app. config. So far the solution has withstanded countless reboots and it always properly brings up the amp on restore.
