Reverse Switch

The reverse switch is used to determine when the vehicle is in reverse gear .

Reverse Switch Input

Select an appropriate input to use for the Reverse Switch. An SPI/DPI or an AVI (Analogue Voltage Input) can be used.

Connection Type

SPI/DPI

An SPI (Synchronised Pulsed Input) or DPI (Digital Pulsed Input) requires configuring of the edge and the type of Sensor to be connected.

Edge Select

Falling is used when the input is grounded when the switch is activated. Rising is used when the input is supplied voltage when the switch is activated.

Sensor Type

Set to Hall Effect for all switch inputs

Pullup

Enables a pullup if required to generate a voltage when the switch is off.

AVI

An AVI will require Switch On and Switch Off voltages to be configured so the Elite ECU can know which voltages on the AVI meet the conditions required.

Switch On Voltage

The voltage either above or below where the switch is considered to be ON. When selecting an appropriate value some consideration should be given to allow for voltage fluctuations.

Switch Off Voltage

The voltage either above or below where the switch is considered to be OFF. When selecting an appropriate value some consideration should be given to allow for voltage fluctuations. Eg. if the switch is at 5V when it is Off and is grounded to 0V when the switch is On, you would set the On voltage to 1.0V and the Off Voltage to 4.0V.

Example 1

The switch is at 5V when it is Off and is grounded to 0V when the switch is On. Correct settings with tolerance would be to set the On voltage to 0.5V and the Off Voltage to 4.5V. i.e. when the voltage falls below 0.5V it is considered to be ON, and when it rises back above 4.5V it is considered to be OFF.

Example 2

The switch is at 2.5V when it is OFF, and is at 12V when it is ON. Correct settings with tolerance would be to set the On Voltage to 4.5V and the Off Voltage to 3.0V. i.e. when the voltage rises above 4.5V it is considered to be ON, and when it falls back below 3.0V it is considered to be OFF.
