DL1PRO-WP / Operation

Operating the DL1 PRO

Description of the plug/connections/lights etc on the DL1 PRO










Front

Start/Stop Logging Button Press once to start logging, again to stop logging.
Status Light This light flashes to indicate that the DL1 PROs processor is operating normally and is ready to log data.

In an error situation this LED blinks a number of times followed by an off period, as shown below.

  • 2 SD Card detection error
  • 3 SD card write error
  • 4 SD card read error
  • 5 FAT file system initialize error
  • 6 Over voltage error
  • 7 Configuration error
  • 8 Firmware error
  • 9 License error
  • 10 Serial number error
  • 11 Calibration error
  • 12 Board test error
GPS Lock Light This light will be on when the GPS receiver has a lock. Details about mounting the GPS antenna are here.
Power On This light illuminates when the DL1 PRO is connected to a valid power supply. Advice about connecting a power supply is here.
Logging This light illuminates when the DL1 PRO is actually logging data to the SD card. When this light is illuminated YOU MUST NOT TURN THE DL1 PRO OFF, OR EJECT THE SD CARD!
SD card Slot This is the slot for the SD or SDHC card.

GND Ground, recommended for grounding analogue sensors.
Ground Ground, recommended for grounding analogue sensors.
+5v1 +5v output, maximum current output 1A. This can be used for powering external sensors
+5v2 +5v output, maximum current output 1A. This can be used for powering external sensors
+12v Power ESSENTIAL! This is the power supply for the DL1 PRO, it needs 10v-15v and about 150mA minimum. Details here.
GND ESSENTIAL! This is the ground for the power supply to the DL1 PRO. Details here.
rL This is the "low level" rpm input that triggers about 5v - this MUST NOT be connected to the ignition coil. Details here.
rH This is the "high level" rpm input that connects to the low voltage side of the coil. Details here.
rG This is the ground for the "high level" rpm input that connects to an HT lead or the low voltage side of the coil. Details here.
F1 Frequency input 1, for connection to an external shaft or wheel speed. Triggers at 3v. Details here.
F2 Frequency input 2, for connection to an external shaft or wheel speed. Triggers at 3v. Details here.
F3 Frequency input 3, for connection to an external shaft or wheel speed. Triggers at 3v. Details here.
F4 Frequency input 4, for connection to an external shaft or wheel speed. Triggers at 3v. Details here.
GPS rf +3.3v GPS antenna connection (gold SMA type). This feeds 3.3v out to the active GPS antenna and takes in the GPS rf signal.
Data Port This single connector actually connects to 2 serial ports and a CAN port. One of the serial ports is generally used to connect to a display unit, such as a DASH2, the other to an ECU interface.
    

"WARNING": To avoid any possible damage to the car paintwork, please take care when mounting magnetic GPS antennas. In particular make sure that there are no dust or grit under the antenna. In some cases it maybe required to add additional protection to the paintwork prior to mounting the antenna to avoid damage.


Sampling Data with the DL1 PRO

  • If used, connect a GPS antenna to the rear of the DL1 PRO.
  • Connect the DL1 PRO to a valid power supply. After a short pause the power light on the front of the unit will come on and the status light will start flashing rapidly.
  • Insert a freshly formatted SD card into the slot, the status light will stop flashing for a second or 2 then start again when the DL1 PRO is ready to log data.
  • Press the "Start/Stop Logging" button on the front of the DL1 PRO, the "Logging" light will come on indicating that the DL1 PRO is writing data to the SD card.

To stop data logging:

  • Press the Start/Stop Logging button on the front of the DL1 PRO; the "Logging" light will go out.
  • ONCE THE LOGGING LIGHT HAS GONE OUT, eject the SD card from it's slot. Power can now be disconnected if required.
  • Put the SD card in a suitable reader and check a file has been written to it.

Advanced operation

You can set the DL1 PRO to automatically start and stop logging based on external inputs or on a timed basis. For more information on how to do this, see the DL1 PRO Configuration software section.

Real Time Output

Practically the whole time the DL1 PRO is powered up, it is outputting data in real time to the external serial port. This can be used for a number of applications including monitoring the data on a PC or streaming to a dashboard or video logger.
