If your installer has not configured your venue yet, follow the steps in the "Nevco ONE Controller Quick Start Guide" to set up your sporting event. Scan the QR code or visit:
First, it's important to familiarize yourself with the operation of the buttons.
The text in the center of a button indicates a short press operation.
The text shaded at the bottom of a button indicates a long press (hold 3 seconds) operation.
Warning: When an event configured with multiple parent/child receivers is started via the One Controller mobile app, no X3 can join the active event. The One Controller mobile app does not currently support adding X3 serial IDs to existing events.
1. Power on the X3: Hold the ON/OFF button (bottom center) for 3 seconds. You will see the "NEVCO SPORTS ONE" splash screen.
2. Battery check: The X3 checks battery levels automatically; replace batteries if a low-battery warning appears.
3. First time connection: The X3 will attempt to connect automatically:
3a. Pre-programmed receiver: If your receiver's serial is pre-set, the X3 connects automatically and displays Connecting to: plus the serial number.
3b. Device Discovery: If no receiver is pre-programmed, the X3 scans for nearby receivers and displays Searching......
When the scan completes, arrow-key to your receiver and press Enter. If your receiver isn't listed, see Device Discovery in the User Manual.
4. Connecting to a different receiver: From the scoring screen, press Options.
Select Options → Main Receiver. The Main Receiver menu shows Device Discovery (scan) and Manual Entry (type serial).
a. Main Receiver → Device Discovery: press Enter to search, then arrow-key to your receiver and press Enter.
b. Main Receiver → Manual Entry: type the serial number with the keypad and press Enter.
5. Select your sport profile: If multiple profiles are available, arrow-key to your selection and press Enter.
You are now connected and ready to control your scoreboard!
Once connected, your X3 displays the tennis scoring screen:
Top line: H (Home), the serve indicator (< when Home is serving), Home's games won in each set (up to 5 sets; current score: 6, 7, 5), and 27 seconds on the serve timer.
Bottom line: G (Guest), the serve indicator (< when Guest is serving), Guest's games won in each set (up to 5 sets; current score: 4, 6, 6), and the FAULT indicator shared for BOTH teams.
Serving player: A < beside H or G marks which player is currently serving (HOME).
When the event is over, hold the ON/OFF button (bottom center) for 3 seconds. Choose:
Leave the event: Your event continues; another device can connect to control the scoreboard.
End the event: The game ends; the scoreboard goes blank.
X3 will not connect to the receiver: Ensure the receiver is powered on and you are within 50–650 ft of the scoreboard.
No display on the X3: Ensure batteries have capacity. If so, remove and re-insert batteries to power cycle the unit.
Connection drops intermittently: Move closer to the receiver. Check for sources of wireless interference (other wireless devices, metal structures). Ensure batteries are not low; a low battery warning may indicate insufficient power for reliable wireless communication.
"No Events Available" displayed on screen: Using the One Controller app, create an event with the sport profile for the X3's sport.
Wrong data on scoreboard:
- Verify you are connected to the correct receiver (turn off and turn back on to see which receiver is being connected to).
- Confirm the correct sport profile is selected.
- Verify Scoreboard Model matches in the receiver's settings via One Controller.
