The Tether Tools Air Direct USB-C to USB 3.0 Micro-B Cable (2-Pack) ADC-3MB is a set of replacement or spare cables designed specifically for the Tether Tools Air Direct Wireless Tethering System.
Key Features and Purpose
For the Air Direct System: This is not a standalone tethering cable. It's an essential component for connecting the Air Direct device to a camera. The cable plugs into the USB-C port on the Air Direct and the USB 3.0 Micro-B port on your camera.
USB-C to Micro-B: The cable has a USB-C male connector on one end, which plugs into the Air Direct, and a USB 3.0 Micro-B male connector on the other, which is a common port on many professional cameras.
Data Transfer Speed: The cable supports USB 3.0 data transfer speeds (up to 5 Gbps), which is critical for wirelessly transmitting the large file sizes (especially RAW files) from your camera to your computer via the Air Direct's Wi-Fi network.
2-Pack: The ADC-3MB comes as a two-pack, providing a backup cable for your Air Direct kit. Having a spare cable is crucial for professional photographers who cannot afford to have a shoot halted by a damaged or misplaced cable.
High-Visibility Orange: Like other Tether Tools products, the cables are a distinctive orange color to make them easily visible on a busy set, reducing the risk of tripping and accidental disconnections.
Length: The cable length is approximately 9 inches (22.86 cm). This short length is intentional, as the cable is meant to be a direct link from the camera to the Air Direct device, which is often mounted on the camera's hot shoe or an L-bracket.

How it Works with the Air Direct System
The Air Direct system is a two-part solution: the hardware (the Air Direct device and this cable) and the software (the Air Direct Utility on your computer).
You connect the ADC-3MB cable to your camera's USB 3.0 Micro-B port.
The other end of the cable plugs into the USB-C port on the Air Direct device.
The Air Direct device creates a dedicated Wi-Fi network.
Your computer, running the Air Direct Utility, connects to this Wi-Fi network.
This setup allows you to wirelessly control your camera and transfer files to your computer using your preferred tethering software (like Capture One, Lightroom, etc.), as if you were using a traditional wired connection.
