Power Connection

Connect RaceCapture/Pro to a power source between 9 and 24V. To fully support all devices and outputs, provide at least a 5A fused connection.

Analog Inputs

  • Active Sensors/Signals

The Analog Input Channels accept a 0-5v input signal (protected up to 45V). Connect the input from a sensor to the appropriate connection of the terminal block.

  • Resistive sensor

When connecting resistive style sensors, like many temperature and pressure sensors, one terminal of the sensor is connected to ground, and the other is connected to the Analog input, with a pullup resistor connected to the +5V Voltage Reference on the terminal block. A 2.2K resistor is recommended for most applications. Our Sensor Breakout Board provides a convenient way to wire up 7 sensors to the RaceCapture/Pro.

Expansion Port

The RJ45 Expansion port located next to the terminal block is provided for future sensor / control expansion.

SD Card Slot

The SD card slot is used to store datalogging sessions. 512MB to 32GB cards are supported.

USB Port

The USB port

LED Indicators

  • Power LED

Indicates the unit is powered up (via 12v supply or USB)

  • LED1

Indicates GPS Activity. Slow flash (1Hz) indicates GPS is actively acquiring. Fast flash (5Hz for 5Hz GPS; 10Hz for 10Hz GPS) indicates GPS is locked on to satellites.

  • LED2

Indicates SD card Logging Activity. The flash rate matches the channel with the highest configured logging rate.

  • LED3

Indicates Telemetry Logging Activity. The flash rate matches the channel with the highest configured logging rate.

Indicates

Pushbutton

Press to manually start / stop a logging session. Note this may be overridden by any on-board scripts that may automatically start or stop logging.

Communication Ports

The communication ports a standard RS232 serial connection with power (up to 5v at 1.5A)

  • Port 1

Used for telemetry expansion module

  • Port 2

used for GPS module

Internal Switches / Jumpers

4 position DIP switch (SW1)

This switch bank configures the 4 outputs for Analog or Frequency/PWM mode. To enable analog mode for a particular output channel, slide the switch for the selected channel to the 'on' position. For Frequency/PWM mode slide the switch to 'off'.

GPIO configuration jumpers

The array of jumper blocks configures the 3 GPIO channels for either digital input or output. To configure a particular channel, move the jumper to either the IN position (for input) or OUT (for output)

  • When configured for input, the channel accepts a 0-5v input.
  • When configured for output, the channel provides an open-drain output that can drive 1A and is thermal / over-current protected with inductive load clamping. When the output is deactivated, a 1K ohm pull-up to +5v is present.

Reset Pushbutton

The reset push-button, if installed, is used as a hard reset for the running firmware.

Test Pushbutton

The test push-button, if installed, is used to load the factory bootloader for re-writing flash. Also see: How to flash RaceCapture/Pro firmware

JTAG header

The JTAG header is used to debug or program the RaceCapture/Pro firmware. This is not needed for normal operation
