The AIU-900 is a pre-assembled autopilot interface unit following the interconnect specifications and component requirements recommended by the manufacturers of certain PFD systems when interfaced with existing 1C388 series autopilot couplers. This unit is intended to provide a convenient solution in a single device with multiple variations for installers to use in place of producing the same circuits from discrete components as specific in PFD installation manuals.
This AIU-900 auto pilot adapter (Alternate Part# AIU-900-D) interfaces the Garmin GDU700/1060 and GI275 to 1C388/388MC/388C388MC/1C388-2/388-3.
