Mechanical Installation InstructionsA. AAU Installation(1) Positioning the AAUBecause the AAU communicates with satellites, the AAU must be positioned on thetop of the fuselage. Try to position the AAU near the middle of the cabin area orslightly to the rear. Many factors influence the performance of the system. Factorsthat influence the final position are as follows:Tail Plane RF BlockageThe tail plane and ventral strake block a small amount of the RF beam. For smallaircraft (less than 12,500 lb [5700 kg]), place the AAU at least 10 ft. (3 m) forwardof the base of the tail plane.Other AntennasTransmissions from the AAU may affect other RF systems. The GPS antenna ismost likely to be affected. Mount the AAU at least 1.65 ft (0.5 m) from the GPSantenna. For GPS antennas with poor filtering or high gain, mount the AAU atleast 5 ft (1.5 m) away. Mount the AAU at least 15 inches (381 mm) from the ADFantenna.Magnetic EnvironmentThe AAU contains magnetometers that can be affected by ferrous materials,magnets, or large currents in cables located nearby. Do not place the AAUdirectly above speakers.Fuselage StructureThe AAU is designed to be positioned above the pressurized area, but otherlocations are acceptable. It can be positioned on either side the the center line ofthe fuselage, but keep the offset to a minimum. Use the template to determine thebest position so that the required holes do not interfere with structure components.Distance from FrontPosition the AAU as far from the front of the cabin as possible to reduce drag,wind noise, lightning strikes, and damage from airborne objects.Engines and APU InletsPosition the AAU out of the engine zone of influence and APU inlets.](https://usermanual.wiki/Honeywell/SCS-1000/User-Guide-188961-Page-172.png)

Ensure that they arealigned so that they will fit in the hollow provided in the base plate. Wire theconnectors together with safety wire.(f) Align the AAU with the mounting holes. Secure the AAU with eight mountingscrews. The torque for the mounting screws is 44 lb--inch.CAUTION: DO NOT EXCEED THE TORQUE LIMITS OF THE MOUNTINGSCREWS.(g) Apply a sealant to the mounting screw heads to prevent water seepage.B. Reinstallation Inspection ProcedureInspect and repair in accordance with Table 7-- 1.Table 7-- 1. AAU Reinstallation InspectionInspection Repair ActionMeasure the resistance from the base plate of theAAU to the fuselage. The resistance must beless than 5 milliohms.Remove the AAU. Clean and check all groundingareas. Replace the AAU.Measure resistance from the tab end (not thescrew) of each lightning diverter strip to thefuselage. The resistance must be less than5 milliohms.Remove the screws at the tab ends. Clean off allsigns of corrosion on the top and bottom of thetab and the screw. Care must be taken not tostress the junction between the tab and the stripthat is bonded to the radome. Tighten andrecheck.Check that the AAU is securely fastened to thefuselage.Tighten any loose screws.Check for any cracking of the fuselage over thearea covered by the doubler plate.Repair the cracks in accordance with acceptedprocedures.Check that the lightning diverter strips are secureon the radome.Reattach the diverter strip ends with epoxyadhesive if they are loose (up to 0.47 in. [12mm]).Carefully, lift the loose ends and clean withalcohol. Abrade the painted surface of theradome and underside of the strip with No. 220sandpaper or finer. Apply adhesive to bothsurfaces and press the parts together. Wipeaway any excess adhesive. Tape the strips downuntil the epoxy has cured.If the loose part of the diverter strip is greater than0.47 in. (12 mm), replace the radome or return tothe supplier for repair.Check the radome for cracks. Replace the radome.Check the radome for excessive erosion. Replace the radome.](https://usermanual.wiki/Honeywell/SCS-1000/User-Guide-188961-Page-210.png)

Operating ModesThe SCS system ASD function may operate in three modes given in Table D--1.Table D--1. ASD Function Modes of OperationMode DescriptionCommand Mode The SCS system ASD responds to AT commands. No remotecommunication occurs.Online Command Mode A data call is taking place and an escape sequence has beeninitiated, after which the SCS system ASD responds to ATcommands during the call.Online Data Mode Once the SCS system ASD is connected, anything arriving fromthe PC is interpreted as data and sent to the remote end and viceversa.4. Basic AT CommandsTable D--2 gives the basic AT commands and their descriptions.NOTE:AT commands may be entered in either upper or lower case (not mixed).Table D--2.
