S.BUS

or

CAN bus /S.BUS

I/O port, connecting to the flight controller (CAN bus) and control of the camera gimbal (S.BUS).

AMIMON provides two types of cables for this port:

  • S.BUS-only cable: For output of S.BUS control signals to the S.BUS input on the camera gimbal.

  • CAN bus-S.BUS cable: 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 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.

Telemetry or

MAVLink

This port is used for MAVLink protocol input from a 3DR flight controller (Pixhawk/APM/ArduPilot). The flight control data from the

MAVLink-supported 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.
