Connecting the RFID Sled to the App

Connecting an RFID sled to the RUFUS Timing App enables seamless semi-automated timing, improving accuracy and efficiency during events. This guide provides detailed steps on how to connect both the Zebra RFD2000 and Zebra RFD8500 sleds to the app.

Before You Begin

  • Bluetooth Enabled: Ensure that Bluetooth is turned on for your mobile device. The RUFUS Timing App requires Bluetooth connectivity to communicate with the RFID sleds.

  • App Permissions: Make sure that Bluetooth permissions are authorized for the RUFUS Timing App.

Connecting the Zebra RFD2000

The Zebra RFD2000 sled is designed to be used specifically with Zebra's TC20 and TC25 mobile computers. Follow these steps to connect:

  1. Attach the Sled: Physically attach the RFD2000 sled to the TC20 or TC25 mobile computer. The sled is designed to snap onto the handheld, creating an integrated system.

  2. Turn on the Sled: Power on the RFD2000 by pressing the power button located on the side of the sled. The LED indicator will turn on, showing that the sled is powered.

  3. Launch the App: Open the RUFUS Timing App on your TC20 or TC25 device.

  4. Bluetooth Authorization: If prompted, allow the app to use Bluetooth to connect to the sled.

  5. Check Connection Status: If the sled is correctly connected, you will see a success message and the status of the sled's battery at the top of the screen. Once connected, you are ready to start reading RFID tags during your timing session.

Connecting the Zebra RFD8500

The Zebra RFD8500 is a versatile sled that can be paired with a range of Android or iOS devices via Bluetooth. Follow these steps to connect:

  1. Power on the Sled: Turn on the RFD8500 sled by pressing the power button until the LED indicator lights up.

  2. Pair via Bluetooth:

    • On your mobile device, go to Bluetooth Settings.

    • Search for available devices and select RFD8500 from the list.

    • Once paired, you will see the RFD8500 listed as a connected device.

  3. Launch the App: Open the RUFUS Timing App on your mobile device.

  4. Authorize Bluetooth Access: When prompted, allow the app to access Bluetooth so it can communicate with the RFD8500.

  5. Verify Connection in the App: If the sled is correctly connected, you will see a success message and the status of the sled's battery at the top of the screen. Once connected, the sled is ready for use.

Using the RFID Sled During Timing

  • Reading RFID Tags: Once connected, the RFID sled will automatically detect and read RFID tags when pressing the trigger. The tag data will be displayed in the session passings list and associated with the corresponding timestamp.

Troubleshooting Tips

  • Connection Issues: If you encounter problems connecting the sled, make sure that Bluetooth is turned on and that the sled is charged.

  • Reconnecting: If the connection is lost, try turning off the sled, restarting Bluetooth on your mobile device, and repeating the pairing process.


By following these steps, you can easily connect your RFID sled to the RUFUS Timing App and start leveraging the power of RFID technology for your event. Whether you are using the Zebra RFD2000 or RFD8500, these devices offer reliable and accurate performance for enhancing race timing operations.
