Package jmri.jmrix.nce
Class NceAIU
java.lang.Object
jmri.jmrix.nce.NceAIU
public class NceAIU extends Object
Model an NCE AIU
These AIUs are numbered ala the cab bus, from 1 to 63. AIU number 1 carries sensors 1 to 14; AIU 2 from 17 to 30, etc.
The array of sensor states is used to update sensor known state only when there's a change on the cab bus. This allows for the sensor state to be updated within the program, keeping this updated state until the next change on the cab bus. E.g. you can manually change a state via an icon, and not have it change back the next time that AIU is polled.
