Reading The DIP Switch Settings Information From The LEDs
The diagnostic LEDs “mirror” the switch settings for the DIP switches requested. For example, if LED 1
is on, then switch 1 is on for the requested DIP switches. If LED 1 is off, then switch 1 is off, and so forth.
When requesting information on the LIU DIP switch settings, the system replies via LEDs 1 through 4.
LEDs 5 through 8 are not used in this application.
