Set up an Atomos USB-C docking station, power your monitor, and offload drive caddies safely. A practical step-by-step guide for on-set and desk workflows.

Quick answer

Connect the Atomos USB-C 3.1 Powered Docking Station II to your computer with its integrated USB cable, insert a single Master Caddy or Master Caddy II, and confirm the drive mounts before offloading. Power your monitor separately through its own USB-C or DC input; the dock is designed for drive caddies, not for charging the monitor itself.

Why the dock and monitor power are separate jobs

It is easy to assume one USB-C hub can both charge an Atomos monitor and offload its recorded drive. In practice, the Atomos USB-C 3.1 Powered Docking Station II is built around a single drive caddy: it accepts one Master Caddy or Master Caddy II at a time and passes its contents to your computer over the integrated USB cable. That focus is useful on a desk or in a transport bag, but it means the dock is not a general-purpose monitor charger.

Power your monitor from the source your rig already uses, such as its dedicated USB-C power input or DC coupler, and treat the docking station as the offload path for the caddy. Keeping those two paths separate avoids the most common setup mistake: plugging a monitor into the dock and wondering why it does not charge.

When a single-caddy dock is the right choice

The single-caddy limit is a deliberate trade-off. If your day involves swapping one recorded caddy at a time from monitor to computer, the low-profile design and integrated cable make the Atomos dock a compact accessory for a desk or transport bag. If you regularly need to mount several caddies at once, plan for a multi-bay reader instead and use the Atomos dock for single-drive offloads.

The powered design also means the dock does not rely on the computer alone to run the drive. Keep the dock's power connection stable during a transfer, especially when you are offloading footage that has not yet been backed up.

Step-by-step Atomos USB-C docking station setup

Power the dock before connecting the computer: Plug the Atomos USB-C 3.1 Powered Docking Station II into its power source first, then connect the integrated USB cable to your computer. Check that the dock has power before inserting a caddy. If the dock shows no power, stop and check the power connection rather than forcing a caddy into an unpowered dock.
Insert one compatible caddy: Slide a single Master Caddy or Master Caddy II into the dock. Do not try to insert a second caddy or a bare drive that is not in a supported caddy. Confirm the caddy seats fully; a partially inserted caddy is the most common reason a drive does not mount.
Confirm the drive mounts on your computer: Open your computer's file browser or disk utility and wait for the caddy to appear. Give the system a moment to recognize the drive before opening folders. If the caddy does not appear, eject and reseat it once, then try a different USB-C port before assuming the drive is faulty.
Power the monitor from its own input: Connect your Atomos monitor to its dedicated USB-C power source or DC coupler. Do not expect the docking station to charge the monitor; the dock is for caddy offload. Label or color-code the monitor power cable and the dock cable so they are not swapped on a busy set.
Offload, then eject safely: Copy or verify your footage, then use your operating system's eject command before removing the caddy from the dock. Never pull a caddy mid-transfer; a safe eject protects the last clip you recorded.
