NOTE: The “Active” column refers to the voltage-state present when the device
(sensor, switch, etc…) is performing its intended function.
For example: item 3 – Front/Right Door Open Detection Switch – Active H.
This indicates that when the Right Door is Open this device is active and
the voltage state at CN7/1 will be “High,” in this case 5 volts dc.
If you require the “Ready” condition values refer to the G081/G092
Connector Layout Tables located on the back of your Point-to-Point.
