Description:
This gauge interacts with the Apollo SL50, SL60, GX50 and GX60 GPS and GPS/COM
radio gauges which come with this archive. It toggles the autopilot between
NAV/GPS mode and corresponds with the installed GPS gauges in the radio panel.
This gauge is available in two configuarations. One for horizontal and one for
vertical mounting.

The power of the ACU is controlled by the central avionic circuit switch in
your panel.

The buttons and lamps:
See the picture ExplACU.bmp which gives an overview of the functions.

The NAV/GPS button toggles the driver for an installed autopilot gauge. If NAV
is selected, the NAV1 (VOR1) instrument drives the autopilot course.
If GPS is selected, the installed GPS gauge drives the autopilot course.

The GPS/SEQ switch has no function, however it is animated and lighted.

The small TEST button checks the operation of all lamps when pressed.

The NAV annunciator lamp is green when NAV mode is active.

The GPS annunciator lamp is green when GPS mode is active.

The MSG annunciator lamp is yellow if a message was generated by the GPS and
was not read yet.

All other annunciators have no function.


Notes:
This is version 1.0 of this gauge and if any updates are required I will release
them. Send me an email if anything doesn't work as expected.

This gauge is programmed completely new with EASYGauge, a wonderful easy to use
WYSIWYG gauge editor by Bluesky Software Development. Have a look at
