Hardware Connection

Hardware setup and wiring guide for the Synchronizer module.

Interface Overview

The Synchronizer provides multiple interfaces for time synchronization:

Interface	Connector	Description
PPS Input	SMA	GPS/GNSS PPS signal input
PPS Output	SMA	Synchronized PPS output
Trigger Out	JST-GH	Camera/LiDAR trigger signals
Ethernet	RJ45	PTP/IEEE 1588 network sync
CAN	JST-GH	CAN bus time distribution
