DL1PRO-WP / TechSpecification

Technical Specification


Memory card Removable SD card up to 32GB on DL1 PRO, fixed internal card of 8GB on DL1 WP
GPS Outputs position, speed, position accuracy and speed accuracy at 5Hz with no interpolation. GPS tracking loops optimised for applications up to about 4g. tracking of all satellites in view. 20Hz raw data storage for post-processed operation
GPS Antenna Magnetic base, 3.3v active antenna with SMA connector.
Analogue Inputs 12 external inputs, 0-25v. All inputs are protected and have a 2nd order filter with corner frequency of 105Hz. Accuracy = 0.4% of measured voltage +-20mV. Sample rate 100Hz as standard, 1kHz optional.
Frequency Inputs 4 external frequency inputs with a maximum input frequency >2kHz. Triggering voltage requires a low input of <1v and a high input of >4v and 15v maximum.
Lap Marker Input Triggering voltage requires a low input of <1v and a high input of >4v and 25v maximum.
Start Sample Input Triggering voltage requires a low input of <1v and a high input of >4v and 25v maximum
Low level outputs 4 low side drivers updating at 10Hz, each capable of driving 500mA.
Power Supply Requirements 12v nominal input, minimum of 10v, maximum of 23v (higher voltages can be accommodated if specified at the time of ordering). Current consumption of about 180mA including GPS, dependant on SD card requirements.

+5v Reference Out Maximum current draw 500mA x 2.

Ignition In Signal (High Level) Designed to connect directly to negative terminal of ignition coil. Can also fire from fuel injectors and from CD ignition systems.
Ignition In Signal (Low Level) Triggering voltage requires a low input of <1v and a high input of >4v and 15v maximum. Suitable for connection directly to most ECU tacho outputs. Maximum input frequency >300Hz.
Case Construction Custom aluminium housing with integral mounting holes. IP67 on DL1 WP.
Connector Type 19 way and 24 way Binder connector
Main Processor 150MHz TI Digital Signal Processor
Serial Port 1 User configurable for messages. Transmission and reception of RT format messages at 115200 baud
Serial Port 2 Used for reception of RT messages at a fixed baud rate of 115200
CAN Port Maximum of 105 individual messages per port, at up to 1Mbit/s
Message transmission with RTR
Optional RAW CAN reception (100Hz standard, 1000Hz with 1000Hz license)
Optional second CAN port for reception and transmission
Computer communication USB port for reflashing, reading/writing configuration, viewing live data, and file transfer. Case mounted on DL1 PRO, on flying lead on DL1 WP. Download speed 2Mb/s
Accelerometers 3 axis, precision digital output. Guaranteed 2g minimum full scale on both axes. Resolution of 0.005g. Optional 6g sensor available as a factory option.
Gyroscope Single axis yaw rate gyro with a maximum rate of 300 degrees / sec.
Vibration Factory tested at 25g, 50Hz sinusoid for 5 minutes (without memory card inserted).
Temperature Factory tested from -20oC to 70oC
Status indicators Power and logging status lights on DL1 PRO, no status lights on DL1 WP (four status indicators on external cable)

"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.
