2.4 - Automotive Ignition Power Sensing (IGN)
The K300 3-pin power input terminal offers automotive ignition sensing. The ignition sensing timing
for power on and off delays can be modified through OnLogic’s microcontroller (MCU) using serial
commands. These commands allow setting the delay on startup after ignition is detected, the delay
until soft and hard shutdown when ignition is lost, and enabling/disabling ignition sensing. For more
information on ignition power sensing, and instructions on using these serial commands from
Karbon series technical support site
