- Put your F21S into pairing mode by following the manufacturer's instructions (usually involves holding the power button).
- In Intiface Central, click "Start Scanning" to find your device, which should appear within seconds.
- On Funscript.org, navigate to the Dashboard and select the "Intiface Central" device option.
- Leave the WebSocket URL as the default ws://127.0.0.1:12345 unless you have changed the port.
- Click "Connect" to establish a connection between Funscript.org and your F21S.
Once connected, the F21S is ready to be used across all Funscript.org features, offering a seamless sync experience that enhances every session. The first time I connected it via Intiface Central, the latency was barely noticeable, which is crucial for maintaining the immersive nature of the experience.
Syncing with Funscript Files
After successfully connecting your device, syncing it with funscript files is the next step. Here's how you can ensure your F21S delivers the interactive experience you're after:
- Load your chosen video alongside a compatible funscript file in the Funscript Player.
- Ensure that the video and the funscript are perfectly aligned using the heatmap and sync offset features available in the player.
- Once satisfied with the preview, hit play, and watch as the F21S translates the script's motions into precise thrusts, perfectly timed with the video content.
In practice, the F21S's synchronization capabilities are one of its strongest suits. The linear actuator's precision translates funscript data into tangible, accurate motions, creating an immersive experience that is both satisfying and easy to control. During my sessions, the consistency of the thrusts was notable, maintaining a steady rhythm that aligned well with the scripted content.

Performance and User Experience
After using the Fredorch F21S for a few weeks, several aspects of its performance stood out. Here's a closer look at the thrusting and sync capabilities, as well as how it integrates with Funscript.org features.
