| Memory card
| Removable SD card up to 32GB, fixed internal card of 8GB
|
| 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 Regulated Output for powering sensors 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.
