Caddx Farsight Quick Start Guide

Product Introduction

The Caddx Farsight offers the following key features:

• Fast Zoom: The Farsight camera boasts an 8x zoom capability with a quick and smooth zooming process, eliminating the wait time associated with traditional zoom lenses. It utilizes a hybrid zoom solution combining optical, digital, and AI algorithms.
• Lightweight Design: With an ultra-compact size of 19mm x 19mm, it offers a more portable alternative to bulky optical zoom lenses.
• Supports analog output functionality.
• Supports remote control for zoom operations.

Installation Direction

During installation, ensure the indicated side is facing upwards to prevent image inversion.

Control Mode

Zoom Function Control: Zoom operations are managed via PWM signals from the flight controller. For instance, a 100% PWM signal duty cycle displays 1x magnification, while a 200% duty cycle provides 2x magnification.

Reset Function Control: An IO-defined switch is used to quickly reset the zoom to 1x magnification from higher zoom levels. When the IO switch is turned off, the zoom reverts to its previous magnification.

Recommended Button Settings:

• Zoom function: Controlled by a rotary switch.
• Reset function: Controlled by a two-position toggle switch.
