Memory | Compact flash type I. Data in FAT16 PC format. Minimum card size 32MB, maximum card size 2GB (limited by FAT16). |
GPS | Outputs position, speed, position accuracy and speed accuracy every 200ms with no interpolation. GPS tracking loops optimised for applications up to about 4g. Tracking of all satellites in view. |
GPS antenna | Magnetic base, 3.3v active antenna with SMA connector |
Analogue Inputs | 8 external inputs, all 12 bit resolution, all 12v full scale. All inputs are protected to twice maximum input voltage |
Frequency Inputs | 4 external frequency inputs with a maximum input frequency >2kHz. Hardware dividers of 4 or 16 to average readings if required. Triggering voltage requires a low input of <1v and a high input of >4v and 15v maximum. |
Lap Beacon Input | Triggering voltage requires a low input of <1v and a high input of >4v and 15v maximum. |
Start Sample Input/Output | Input requires grounding to start sampling and again to stop sampling. Open collector output with a maximum current of 50mA |
Power Supply Requirements | 12v nominal input, minimum of 10v, maximum of 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 capacitively coupled to the high-tension side. |
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 | Extruded aluminium anodised black, nominal case thickness 2mm. End panels CNC cut carbon fibre. |
Connector Type | Spring loaded positive retention for ease of installation |
Main Processor | 24MHz RISC with embedded flash program memory |
GPS Serial Port | User configurable for baud rate and messages. Factory set at 4800 baud and outputting NMEA messages of $GPRMC and $GPGGA, |
DL1 Serial Ports | 2 separate ports. Port 1 fixed at a baud rate of 115200 baud. Whilst logging outputs all data from all channels at 100Hz. Also used for reflashing, diagnostics and configuration. Port 2 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. Guaranteed 2g minimum full scale on all axes. Resolution of 0.005g. Optional 6g sensor available as a factory option. |
Vibration | Factory tested at 25g, 50Hz sinusoid for 5 minutes (without compact flash card inserted). |
Temperature | Factory tested from -20oC to 70oC |
