What are the specifications for the Digital Input (DI) and Output (DO)?

  • Digital Input (DI): Used to detect switch states (e.g., ignition, door open). It defaults to a 10k pull-down resistor but can be configured for pull-up.
  • Digital Output (DO): This is an open-drain output capable of driving up to 300mA. It is typically used with an external relay to control vehicle accessories.
