DRIVE-2 Analog output cable

This cable provides the 5 DRIVE-2 signals as analog outputs.

Preliminary specifications for signals
Signal Type Impedance Range Resting Notes
Gas Raw Analog 1kΩ 0 - 5V 3.5 +/- 0.2 V Drops to ~3V +/- 0.2 when gas fully pressed
Brake Raw Analog 1kΩ 0 - 5V 3.5 +/- 0.2 V Drops to 3V +/- 0.2 when brake fully pressed
Index Raw Analog 1kΩ 0 - 5V 3.9 +/-0.3 V Drops to < 0.5V when steering not centered
Button Raw Analog 1kΩ 0 - 5V 3.9 +/-0.3 V Drops to < 0.5V when button pressed
Steering PWM Analog 10kΩ 0 - 5V 2.5 +/- 0.1 V Drops in CW direction, Increase in CCW, wraps at ~180°

The steering signal can be scaled through firmware so contact us if you would like a different range setting. The other 4 signals are "raw" detected light signals, without conditioning in firmware. So, for example, the button signal will move in an almost switch-like way from ~4V to ~0V when pressed, but you will be able to see that it is inherently analog (if you press it very gradually you can achieve outputs anywhere in the 0.5 to 4V range). The firmware thresholds the signal, and adds hysteresis, to debounce it and to give only a high or low output.

We show the output impedance here to emphasize that these signals should only be used with high impedance inputs.
