DL1Sport / Operation

1. Operating the DL1 SPORT

1.1 Description of the plug/connections/lights etc on the DL1 SPORT

Front

Start/Stop Logging Button

Press once to start logging, again to stop logging.

Status Light

This light flashes to indicate that the DL1s processor is operating normally

GPS Lock Light

This light flashes when the internal GPS system is locked on. It flashes once slowly then a quick "blink" for each satellite it has locked onto. Details about mounting the GPS antenna are here.

Power On

This light illuminates when the DL1 SPORT is connected to a valid power supply. Advice about connecting a power supply is here.

Logging

This light illuminates when the DL1 SPORT is actually logging data to the compact flash card. When this light is illuminated YOU MUST NOT TURN THE DL1 SPORT OFF, OR EJECT THE COMPACT FLASH CARD!

Compact Flash Slot

This is the slot for the compact flash card. There are more details here.

Rear

A1

Analogue input 1, for use with external sensors maximum input 15v.

A2

Analogue input 2, for use with external sensors maximum input 15v.

A3

Analogue input 3, for use with external sensors maximum input 15v.

A4

Analogue input 4, for use with external sensors maximum input 15v.

A5

Analogue input 5, for use with external sensors maximum input 15v.

A6

Analogue input 6, for use with external sensors maximum input 15v.

A7

Analogue input 7, for use with external sensors maximum input 15v.

A8

Analogue input 8, for use with external sensors maximum input 15v.

GND

Two ground connections, use one for power and the other one for sensor ground connections.

+5v

+5v output, maximum current output 50mA. This can be used for powering external sensors

+12v

ESSENTIAL! This is the power supply for the DL1 SPORT, it needs 10v-15v and about 150mA minimum. 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 ignition 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.

Trigger

Grounding this pin has the same effect as pressing the start/stop logging button on the front of the DL1 SPORT.

Lap

When grounded during data logging a new lap marker will be added at the current location.

Status

Used to trigger starting and stopping of data logging on a GoPro camera.

GPS

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

Used for either streaming data from the DL1 SPORT to a display or VIDEO recorder, or to provide additional data such as from 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.

1.2 Sampling Data with the DL1 SPORT

If used, connect a GPS antenna to the rear of the DL1 SPORT Connect the DL1 SPORT 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 compact flash card into the slot, the status light will stop flashing for a second or 2 then start again when the DL1 SPORT is ready to log data Press the "Start/Stop Logging" button on the front of the DL1 SPORT, the "Logging" light will come on indicating that the DL1 SPORT is writing data to the compact flash card

To stop data logging:

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

Advanced operation

You can set the DL1 SPORT to automatically start and stop logging based on either acceleration or speed, for more information on how to do this see the DL1 SPORT configuration page here.

1.3 Real Time Output

Practically the whole time the DL1 SPORT is powered up it is outputting data in real time to its external serial port, this can be used for a number of applications including providing data to a VIDEO4 unit, one of our DASH displays, and for checking the logger inputs using the monitor software.
