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.

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
