CORE SYSTEM DIAGNOSTIC INDICATORS
Transferring Configuration Files to Device:
When you are finished with your configuration and are ready for transfers, there are two ways to transfer to your system. You can just hook up USB to
Core without power to transfer the configuration, but the configuration will not transfer to the internal siren or internal IO until power and ignition is applied.
For this configuration to reach other WecanX devices, Core must be connected and initialized to the other devices in the configuration. Cores diagnostic
indicators are always on and during transfer the Status indicator will be solid or flashing white and the activity indicator will flash Blue to show
communication. When the configuration is finished transferring, the devices diagnostic indicator will either go solid Green or turn off. (This depends on
whether or not you have turned device diagnostic indicators on in "configuration settings") If a large DVM tone is being transferred to an external siren or
howler, the device will display a blinking Red indicator while it is receiving the configuration data only if the diagnostic indicator is enabled in the
configuration. If the indicators are turned off, you will only have the Status and Activity indicators on the Core controller to determine the state of the
configuration.

Idle States:

After Core is initialized and all configuration data has been propagated, Core will enter an Idle state and wait for inputs and instructions pending the events
that you programmed. Cores Activity indicator is always on and will blip every time it is processing a communication. If an analog or OBDII connection is
present, the activity indicator will always be showing activity in an idle state. The activity indicator will blip every time any input state change is senses.
This is helpful to see if device inputs or OBDII inputs are sensed by Core. When testing an input, you can watch for the Activity blip on Core to verify that
Core is reading that input state change. If no blip occurs, verify you have made all the correct connections. If everything on the WecanX bus is initialized,
there is a valid configuration and everything on the bus is in the configuration then the Core Status indicator will be a steady Green. If there are devices on
the bus that are initialized but they are not present in the configuration, then the Status indicator will be steady Green with a Red blip. If there is no valid
configuration on Core, then the Status indicator will flash Red only. If Core is not in one of these idle states, then Core is currently in the middle of another
process as outlined in the diagnostic indicator chart.

System Shutdown:

The entire Core system is designed to always be connected to 12vdc. Every device, including main Core controller, has a built-in sleep function that
minimizes its drain on the battery when in this mode. Applying ignition voltage to the ignition pin of Core will wake up the system and removing the ignition
voltage will put Core to sleep. After about 3 seconds, all other devices connected to Core via WecanX will go to sleep and turn off diagnostic indicators.
