Description

1

Micro HDMI IN

For receiving video from the camera.

2

Power Connector

Input rating: 8-26 VDC (3−6 cells).

3

S.BUS/CAN bus

or

S.BUS/MAVLink

I/O port, connecting to the flight controller (CAN bus or MAVLink) and control of the camera gimbal (S.BUS). The cable for this port can support either of the following options:

  • CAN bus-S.BUS: Allows both CAN bus telemetry input from the A2/NAZA flight controller (to be overlaid on the video via OSD) and S.BUS control output to the S.BUS input on the camera gimbal.

  • S. BUS-MAVLink/Telemetry: Allows both MAVLink protocol input from Pixhawk/APM/ArduPilot flight controller (to be overlaid on the video via OSD) and S.BUS control output to the S.BUS input on the camera gimbal.

The flight control data from the flight controller is overlaid on an On Screen Display (OSD). Telemetry information includes flight mode, number of connected GPS satellites, speed, height and more. To receive telemetry data on the Ground Unit, the Air Unit should be connected to the drone’s telemetry port. For more information, refer to Supported Remote Controls, Gimbals and Telemetry Flight Controllers.

S.BUS properties can be configured using the CONNEX Management application for Windows / MAC or for Android devices.

Note

AMIMON recommends using the CONNEX link for gimbal control ONLY and NOT for full drone control.

Note

  • The CAN bus port and USB port (for firmware upgrade) should not be connected at the same time.

  • Do not connect the S.BUS/CAN bus cable under voltage.
