The MYLAPS RC4 Pro Transponder is a compact and lightweight device designed for tracking and timing in racing applications. It features a pitch-black design with a short cable for a perfect fit and optimized lightweight construction, weighing only 3 grams.

Function Description:

The RC4 Pro Transponder is used to transmit a unique signal that allows for precise timing and lap counting in various racing events. It operates by magnetic induction, sending data to a receiver channel, typically from ch3 or higher. The device is designed to be mounted horizontally on a vehicle, no higher than 15 cm (6 inches) from the track, to ensure optimal signal strength. All practice and event results are accessible through the free MYLAPS Speedhive App, available on both the App Store and Google Play.

Important Technical Specifications:

• Dimensions (WxLxH): 15.7 x 18.0 x 4.5 mm (0.62 x 0.71 x 0.18 in)
• Weight: 3 g
• Cable Length: 80 mm (3.1 in)
• Max. Speed: 120 km/h (75 mph)
• Signal Transfer: Magnetic induction
• Transponder Position: Max. Height 15 cm (6 in)
• Connection Plug: Standard Servo plug
• Operating Voltage: 2.8 – 16 VDC (recommended: 3.5 – 12 VDC)
• Power Consumption: 19mA @ 6 VDC
• Humidity: Max. 90% relative
• Temperature Range: 0-50 °C (32-122 °F)
• Code Resolution: 1.5 ms
• Power Source: Free receiver channel (ch3 or up)
• Wire Insulation: Aerospace/MIL-spec high-temp PTFE (Gasoline/Nitro resistant)

Usage Features:

• Mounting: The transponder should be mounted horizontally to ensure the strongest signal. Avoid placing metal or carbon fiber between the transponder and the track, as this can weaken the signal. It can be fixed using double-sided tape.
• Power Connection: Connect the transponder to a free receiver channel (ch3 or higher) using a standard Servo plug. If a free channel is not available, a Y Splitter can be used.
• Polarity: Ensure the correct polarity of the servo connector when connecting to the receiver. If wires are shortened, refer to Figure 2 for proper polarity.
• LED Indicator: The transponder features an LED that blinks red when powered.
  • 1 Hz (1x per second) blink: Indicates normal operation with voltage between 3.3 VDC and 12 VDC.
  • 5 Hz (5x per second) blink: Indicates that the voltage is lower or higher than recommended, meaning the transponder may not function properly.
• Results Access: All practice and event results are available through the MYLAPS Speedhive App, allowing users to check their performance.

Maintenance Features:

• Compliance: The device complies with part 15 of the FCC Rules, meaning it must not cause harmful interference and must accept any interference received.
• RF Exposure: To comply with FCC RF exposure requirements, the transponder should be used or installed at locations with at least 20cm separation between the antenna and all persons.
• Support: In case of any issues, users are advised to contact the MYLAPS support team via their website, www.mylaps.com.
• Warning: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.
