Digital Inputs / Ignition Input
The digital inputs are all low-pass filtered and transient protected. To activate the inputs, connect a
positive voltage between the input and the GND connector.
Please note:
The DIN 5/IGN input is a special input as it also functions as the ignition input. If the
ignition input is activated with a logical high or low (Wait For Event mode only), when the C660 is
in low power mode, it will wake-up the unit. A power apply will also wake-up the unit, if it is in
power-down mode or WaitForEvent mode with power Apply and/or ignition selected for wake-
up. The ignition is de-bounced with a period between 1-2 ms, when used as a digital input. So any
logical level applied to this input must be greater than 2 ms to be valid. The DIN 5/IGN input is
available on both the X1 power connector and the X3 connector together with the other digital
inputs – only one should be used at a time.
The power management allows the possibility to configure a wake-up on one or more digital
inputs with individually configured falling- or rising edge detection. Please consult the M2M
CONTROL IDE documentation for additional information.
