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 1/IGN input is unique as it also functions as the ignition input. If the ignition
input is activated with a logically high or low (Wait For Event mode only), it will wake up the unit
when the RTCU is in low power mode. A power apply will also wakeup the unit, if it is in power-
down mode or WaitForEvent mode with power Apply and/or ignition selected for wakeup.
The power management allows the possibility to configure a wakeup on one or more digital inputs
with individually configured falling- or rising edge detection. Please consult the RTCU IDE
documentation for additional information.
