3. Setup Guide
3.1. Connecting the ANT+ Stick
- Identify a USB Port: Locate an available USB port on your computer (PC or Laptop).
- Connect the Extension Cable (Recommended): For optimal performance and range, especially if your bike trainer is not directly next to your computer, connect the 3-meter USB extension cable to your computer's USB port first.
- Insert the ANT+ Stick: Plug the CYCPLUS USB ANT+ Stick Dongle Adapter into the female end of the extension cable. If not using the extension cable, plug the dongle directly into your computer's USB port.

3.2. Driver Installation
The CYCPLUS USB ANT+ Stick is designed to be plug-and-play on most Windows and macOS systems. Upon connecting the device, the necessary drivers should install automatically.
- Automatic Installation: Allow a few moments for your operating system to detect the new hardware and install the drivers. You may see a notification indicating successful installation.
- Manual Driver Download (If Needed): In rare cases, if the drivers do not install automatically or if you experience connectivity issues, you may need to manually download them. You can contact CYCPLUS customer service for assistance or visit the official ANT+ website for generic ANT USB2 drivers: http://www.thisisant.com/assets/resources/Software%20Tools/ant_usb2_drivers.zip

4. Operation
Once the ANT+ Stick is connected and drivers are installed, you can begin using it with your preferred cycling software.
4.1. Using with Cycling Software
- Launch Software: Open your cycling application (e.g., Zwift, TheSufferfest, TrainerRoad, Rouvy) on your computer.
- Pair Devices: Navigate to the device pairing or sensor connection section within your software. The exact steps may vary by application, but generally involve searching for nearby ANT+ devices.
- Select Sensors: Your software should detect your ANT+ enabled bike trainer, heart rate monitor, speed sensor, cadence sensor, and power meter. Select the devices you wish to connect.
- Begin Activity: Once your devices are paired, you can start your virtual ride or training session. The ANT+ Stick will transmit data from your sensors to the software in real-time.

4.2. Optimizing Signal Reception
For the best performance, especially with the 3-meter extension cable:
- Proximity: Position the ANT+ Stick as close as possible to your ANT+ sensors (bike trainer, heart rate monitor, etc.). The best performance is typically achieved within 3 meters.
- Line of Sight: Ensure there are no major obstructions (e.g., metal objects, large furniture) between the ANT+ Stick and your sensors.
- Interference: Keep the ANT+ Stick away from other electronic devices that might cause interference (e.g., Wi-Fi routers, microwaves, other wireless devices).
5. Troubleshooting
If you encounter issues while using your CYCPLUS USB ANT+ Stick, refer to the following troubleshooting tips:
5.1. Device Not Recognized / Drivers Not Installing
- Try Another USB Port: Plug the ANT+ Stick into a different USB port on your computer.
- Restart Computer: A simple restart can often resolve driver recognition issues.
- Manual Driver Installation: If automatic installation fails, download and install the drivers manually from the link provided in Section 3.2.
- Check Device Manager (Windows): Open Device Manager and look for the ANT USB device. If there's a yellow exclamation mark, it indicates a driver issue. Right-click and select "Update driver" or "Uninstall device" and then replug the stick.
5.2. Frequent Disconnections / Signal Drops
- Optimize Placement: Ensure the ANT+ Stick is within 3 meters of your sensors and has a clear line of sight. Use the extension cable to position the dongle closer to your bike.
- Reduce Interference: Move other wireless devices (Wi-Fi routers, cordless phones, Bluetooth devices) away from the ANT+ Stick and your sensors.
- Check Sensor Batteries: Ensure all your ANT+ sensors (heart rate monitor, speed/cadence sensors, power meter) have fresh batteries.
- Software Settings: Some cycling applications may have specific ANT+ settings or protocols (e.g., ANT FEC vs. direct trainer protocol). Experiment with these settings if available.
- USB Power: If using a USB hub, ensure it is a powered hub to provide sufficient power to the dongle.
5.3. Sensors Not Pairing
- Activate Sensors: Ensure your ANT+ sensors are awake and transmitting. For example, spin your bike's wheel or pedals, or wear your heart rate monitor.
- Check Compatibility: Verify that your sensors are indeed ANT+ compatible.
- Software Scan: Ensure your cycling software is actively scanning for new devices.
