Power level

• Initially, the Wireless Racing Panel transmits at its highest power level (Lvl 7, 4 dBm). At this power level, the range in line of sight can be up to 100 meters. However, you can adjust this power level to optimize between battery life and effective radio range.
• Lowering the power increases battery life but reduces range (down to approximately 1 meter, placement dependent).
• To change the transmit power of the Wireless Racing Panel:
• Set the desired power level using the rotary switch highlighted in yellow, where 1 is the lowest transmit power, 7 is the highest power. Position 8 is also treated as the highest power.

When the rotary switch indicates the desired power level, confirm the change by pressing the 4 buttons highlighted in blue for a minimum of 3 seconds. Confirmation of the power change will be reflected in the Tx power lvl channel in the channels window of the Light Client. An example of changing the power from the highest to the lowest is shown in the image below:

Warning
If the set transmit power is too low, data from the Wireless Racing Panel may not be transmitted to the Wireless Receiver, the power level in the Light Client will not be updated.

Communication details

• The Wireless Racing Panel prioritizes battery life by transmitting signals to the Wireless Receiver only when its state changes (e.g., turning a rotary switch or pressing a button). This eliminates redundant updates and preserves battery power. However, it’s essential to remember that if the Wireless Receiver misses a signal due to weak reception or insufficient power, the panel’s state won’t be automatically refreshed on the CAN bus. Therefore, selecting the appropriate signal power level based on the intended distance and placement of the Wireless Receiver is crucial for ensuring reliable communication and control.
• With multiple Wireless Racing Panels connected to a single Wireless Receiver, a key aspect to understand is transmission priority. When a state change occurs on any panel, only the state of the most recently changed panel is transmitted on the CAN bus.

Example

• Imagine a two-driver endurance race, each with their own Wireless Racing Panel.
• Driver 1 makes adjustments to their panel, and the updated state gets transmitted to the Wireless Receiver and subsequently the CAN bus.
• Now, Driver 2 enters the car with their panel. Crucially, until Driver 2 takes any action (even a simple button press), the CAN bus will continue transmitting the previous driver’s settings, potentially causing unexpected behavior if not aware of this prioritization system.
