Currently I am using the AIU to monitor the status of BD20s. I have not used the AIU to monitor turnout position.
To monitor turnout position with the AIU, am I correct in understanding that I would need to run an additional circuit from an AIU port to the contacts on the Tortoise Switch machine (that would close when the turnout is in a closed position) and back to the ground connection on the AIU. The AIU port would light up if the switch was closed. Then edit the Turnout table to assign that AIU port address as Sensor 1?
