DL2 specifications
| Memory | Compact flash type I, FAT16 PC format, 128MB to 1GB. |
| GPS | Logs position, altitude, speed, heading, position accuracy, speed accuracy, heading accuracy. Tracks all satellites in view. |
| 5Hz | Logs all data at 5Hz (every 200ms). Typical error (CEP) 3m, under good conditions this is reduced to about 1m. |
| GPS antenna | Magnetic base, 3.3v active antenna with SMA connector. |
| Analogue Inputs | 16 external inputs (optional), all 12 bit resolution, with a maximum input of 12v and resolution of about 3mV. All inputs are protected to twice maximum input voltage. Input impedance >100k. |
| Frequency Inputs | 4 external frequency inputs with a maximum input frequency >2kHz. Suitable for wheel, shaft, or engine speeds, may require additional sensors. |
| Lap Beacon Input | Triggering voltage requires an input of over 4v. |
| Start Sample Input/Output | Input requires grounding to start sampling and again to stop sampling. Open collector output with a maximum current of 50mA. |
| External Power Supply Requirements | 12v nominal input, (between 10v and 15v). Current consumption of about 180mA including GPS, dependant on compact flash card size. |
| +5v Reference Out | Maximum current draw 100mA, tolerance 1%. |
| Ignition In Signal (High Level) | Triggered by fast voltage transients. Can be connected directly to the low tension side of the ignition coil, or coupled to a high-tension lead. |
| Ignition In Signal (Low Level) | Requires a triggering voltage of 4V. Suitable for connection directly to most ECU tacho outputs. Maximum input frequency >300Hz. |
| Case Construction | CNC aluminium, black anodised. Front cover high impact polycarbonate. Sealed using ‘o’ rings. |
| Connector Type | 4 x Binder 723 Series 12-way male bulkhead connectors (for all connections except GPS antenna), 1 x SMA female bulkhead connector (GPS antenna). |
| Main Processor | High performance 40MHz RISC with embedded flash program memory. |
| GPS Serial Port | User configurable for baud rate (1 or 5Hz) and messages. Factory set at 4800 baud and outputting NMEA messages of $GPRMC and $GPGGA. |
| DL2 Serial Ports | Serial output to drive our dashboard or video overlay products. Serial input used for inputting RS232 data for storage during a run, from an ECU, OBDII adapter or any other compatible device. |
| Accelerometers | 3 axis, precision digital output. 2g full scale on all axes. Resolution of 0.005g. Optional 6g sensor. |
Technical specification (options)
| 20Hz (optional) | Logs all data at 20Hz (every 50ms), advanced processing for both a higher update speed and more accurate results than the 5Hz system. Typical error (CEP) 3m, under reasonable conditions this is reduced to about 1m. |
| Battery power (optional) | Approximately 8 hours continuous use from fully charged, depending on compact flash card and external loads. |
