VR Trigger Configuration
HALL Trigger Configuration
SW10 and SW11: Analogue input PULLUP resistors (2.49k) to +5V for Temperature Sensor
Analogue input pull up settings to use for temperature inputs: Most of Analogue inputs can be used as temperature inputs with 2.49Kohm pull up to +5v resistors. These resistors can be enabled by flipping toggle switch to ON position.
SW12 Digital Input PULLUP resistors (680k) to +5v
Digital input 680kohm pull up resistors to +5v. If your digital input requires pull up resistor taht can be enabled by flipping toggle switch to ON possition.
SW9 CAN bus terminator Resistors and Knock Audio Filters
- toggle switch is to ON possition to enable 120ohm terminating resistor on CAN1
- toggle switch is to ON possition to enable 120ohm terminating resistor on CAN2
- toggle switch is to ON possition to enable 3.3nF filter capacitor on KNOCK 1 Input
- toggle switch is to ON possition to enable 3.3nF filter capacitor on KNOCK 2 Input
