Apex Dual Orin External Wakeup#

Description#

The external wake-up function means that the device does not start after it is powered on. An external signal provided by the user controls whether to start.

This function allows users to have more flexibility in power control and can be applied to the power-on timing issues faced by users when integrating multiple different devices.

Apex Dual Orin provides two ways to wake up the system.

  • IGN Wakeup

  • CAN Wakeup

Glossary#

Low power mode: TC397 in low power mode, master Orin and slave Orin are off.

Normal mode: TC397, master Orin, and slave Orin, work in normal mode.

Off mode: TC397, master Orin, slave Orin are power off.

Wakeup: Devices enter from low power mode to normal mode.

Sleep: Device from normal mode to low power mode.

IGN Wakeup#

Usually only used in scenarios where local wakeup is used.

When only using IGN to wake up, you need to set the dial code to the following position and do not connect to the interface for waking up CAN. The system is only controlled by IGN signals.

  • Under IGN mode：

    • Power is off.

    • System has power, in low power mode, IGN signal is low.

    • IGN signal becomes high, will trigger system wakeup. System enter normal mode. During normal mode, IGN signal should keep high voltage.

    • IGN becomes low, system will enter low power mode.

CAN Wakeup#

Usually used in scenarios where a special TBOX is used for wake-up. IGN signals should not be connected at this time. The system is only controlled by CAN signals.

  • The system is in a power off state.

  • The system is in a low power state.

  • Wake-up CAN packet received.

  • After receiving the wake-up packet, the data to wake up the CAN interface will no longer have any effect.

  • The system enters normal mode.

  • TC397 triggers the system to enter low power mode again.
