Controller Area Network (CAN) Interface
The AGX Xavier Series Module integrate two independent CAN ports/channels which support connectivity
to two CAN networks. The CAN interfaces are routed to the baseboard via a 4-Pin Miniature 1.25mm Pitch
latching connectors.
CAN Transceiver interfaces between the CAN protocol controller and the physical bus. It
enables high-speed automotive applications using baud rates from 60 Kbaud up to 1 Mbaud and provides
differential transmission capabilities to the bus and differential receiver capabilities to the CAN protocol
controller.
of the Addendum on configuring the interface.
Utility Header Connector
A 2X3 Utility Header connector on the baseboard implements the Power button, Reset and Force Recovery
signals through the on-board switches.
LED Indicators
The baseboard hosts the LED Indicators. The on-board LED Indicator panel is located to the left at the
baseboard edge. The LEDs are displayed on a silkscreen panel with a description of their function and status
as listed in the table below.
