NOTE:
One of these inputs (In1) is also used to power on the device from the shutdown state.
For proper power management implementation, the input must be connected to the
vehicle's ignition switch. The platform provides various software control options for this
essential feature. For more details, refer to the
Digital I/O and Power Management
sections of the Developers Guide .

For the disposition map of the Digital Input1 and Digital Output signals of this port on Main Terminal
“Con1” Connector , see page 38 .
For the disposition map of the Digital Input2 signal of this port on Enhanced Terminal “Con2” Connector ,
see page 39 .
In the Fixed-mount mode, the Digital Input1 and Digital Output require the Main Accessory Cable and
Digital Input2 requires the Enhanced Accessory Cable connection.
