HERELINK
This section will describe how to connect and configure Air Unit of Herelink & Camera to XBLink Plus.

Hardware Setup
Connect Pixhawk
Method 1: Connect to both XBLink and Herelink Air Unit.
In case the telemetry port of flight controller is unoccupied, we highly recommend to use this method to ensure stable and reliable telemetry signal.

Method 2: Connect only to XBLink
XBLink will read telemetry data, then stream it through ethernet to Herelink Air Unit and 4G at the same time.

Connect Herelink Air Unit
Connect directly to ETH0 port's XBLink.
In case you are using USB port of XBLink for IP Cameras or USB Cameras, we recommend you connect Herelink Air Unit to XBLink ETH port as below.


Warning: GND signal of Herelink must be connect to XBLink to prevent data loss
