Receiver Installation

In gas and glow aircrat install the main receiver using the same method you would use to installa conventional receiver in your aircrat. Typically, wrap the main receiver in protective oam andasten it in place using rubber bands or hook and loop straps.

Alternately, in electric airplanes or helicopters, its acceptable to use thick double-sided oam tapeto asten the main receiver in place.

Mounting the remote receiver in a slightly dierent location, even just inches away rom theprimary receiver, gives tremendous improvements in path diversity. Essentially, each receiversees a dierent RF environment and this is key to maintaining a solid RF link, even in aircrat thathave substantial conductive materials (e.g. larger gas engines, carbon ber, pipes, etc.), whichcan weaken the signal.

Using servo tape, mount the remote receiver keeping the remote antennas at least 2 inches awayrom the primary antenna. Ideally, the antennas will be oriented perpendicularly to each other. Inairplanes, weve ound it best to mount the primary receiver in the center o the uselage on theservo tray and to mount the remote receiver to the side o the uselage or in the turtle deck.

In helicopters, there is generally enough room on the servo tray to achieve the necessary separation.If necessary a mount can be fashioned using clear plastic to mount the external receiver.

Important: Y-Harnesses and Servo ExtensionsWhen using Y-harnesses or servo extensions its important to use standard non-amplied

Y-harnesses and servo extensions as this can/will cause the servos to operate erratically or notunction at all. Amplied Y-harnesses were developed several years ago to boost the signal orsome older PCM systems and should not be used with Spektrum equipment. Note that whenconverting existing models to Spektrum be certain that all amplied Y-harnesses and or servoextensions are replaced with conventional non-amplied versions.

BindingThe receiver must be bound to the transmitter beore it will operate. Binding is the process oteaching the receiver the specic code o the transmitter so it will only connect to that specictransmitter.

1. To bind an AR7600 to a DSM2 transmitter, insert the bind plug in the BATT/BIND port on thereceiver.

AR7600 User GuideThe AR7600 ull range 7-channel receiver eatures DSM2 technology and is compatible withall Spektrum and JR aircrat radios that support DSM2 technology including: JR12X, X9303,Spektrum DX7, DX6i, DX5e and Module Systems.

Note: The AR7600 receiver is not compatible with the Spektrum DX6 parkfyer transmitter.

PatentedMultiLinkReceiverTechnologyThe AR7600 incorporates dual receivers, oering the security o dual path RF redundancy. Aninternal receiver is located on the main printed circuit board, while a second external receiveris attached to the main board with a 6-inch extension. By locating these receivers in slightlydierent locations in the aircrat, each receiver is exposed to its own RF environment, greatlyimproving path diversity (the ability or the receiver to see the signal in all conditions).

AntennaPolarizationFor optimum RF link perormance its important that the antennas be mounted in an orientationthat allows or the best possible signal reception when the aircrat is in all possible attitudes andpositions.Thisisknownasantennapolarization.Theantennasshouldbeorientedperpendiculartoeachother;typicallyoneverticalandonehorizontal(seeReceiverInstallation).Theremotereceivers antenna should be mounted in a position perpendicular at least 2 inches away romthe main receivers antenna using double-sided oam tape.

Note:To bind an aircrat with an electronic speed controller that powers the recethe throttle channel (ESC/BEC), insert the bind plug into the BATT/BIND porreceiver and the throttle lead into the throttle (THRO) port. Proceed to Step

2. Power the receiver. Note that the LED on the receiver should be fashing, indicatireceiver is in bind mode and ready to be bound to the transmitter.

3. Move the sticks and switches on the transmitter to the desired ailsae positionsand neutral control positions).

4. Follow the procedures o your specic transmitter to enter Bind Mode, the system

connect within a ew seconds. Once connected, the LED on the receiver will go sindicating the system is connected.

5. Remove the bind plug rom the BATT/BIND port on the receiver beore you powetransmitter and store it in a convenient place.

6. Ater youve set up your model, its important to rebind the system so the true lowneutral control surace positions are set.

IMPORTANT: Remove the bind plug to prevent the system rom entering bind motime the power is turned on.

RangeTestingBeore each fying session and especially with a new model, it is important to perorm a rangecheck. All Spektrum aircrat transmitters incorporate a range testing system which, whenactivated, reduces the output power, allowing a range check.

1. With the model restrained on the ground, stand 30 paces (approx. 90 eet/28 meters) awayrom the model.

2. Face the model with the transmitter in your normal fying position and place yourtransmitter into range check mode.

3. You should have total control o the model with the button depressed at 30 paces (90eet/28 meters).

4. I control issues exist, call the Product Support Team in the U.S. at 1-877-504-0233 orurther assistance. In the UK or Germany use one o the ollowing contacts.

AdvancedRangeTestingFor sophisticated models that have signicant conductive material in them, the advanced rangetest using a fight log is recommended. The advanced range check will conrm that the internaland remote receivers are operating optimally and that the installation (position o the receivers)isoptimizedforthespecicaircraft.ThisAdvancedRangeCheckallowstheRFperformanceofeachreceivertobeevaluatedandtooptimizethelocationsoftheremotereceiver.

AdvancedRangeTest1 Plug a Flight Log (SPM9540 - optional) into the Batt/Data port on the AR7600 and turn on

the system (Tx and Rx).2. Advance the Flight Log until F-rame losses are displayed by pressing the button on the

Flight Log.3. Have a helper hold your aircrat while observing the Flight Log data.4. Standing 30 paces away rom the model, ace the model with the transmitter in your

normal fying position and put your transmitter into range test mode. This causes reducedpower output rom the transmitter.

5. Have your helper position the model in various orientations (nose up, nose down, nosetoward the Tx, nose away rom the Tx, etc.) while your helper watches the Flight Log notingany correlation between the aircrats orientation and rame losses. Do this or 1 minute.The timer on the transmitter can be used here.

ReceiverPowerSystemRequirementsInadequate power systems that are unable to provide the necessary minimum voltage to thereceiver during fight have become the number one cause o in-fight ailures. Some o thepower system components that aect the ability to properly deliver adequate power include:Receiverbatterypack(numberofcells,capacity,celltype,stateofcharge) TheESCscapabilitytodelivercurrenttothereceiverinelectricaircraft Theswitchharness,batteryleads,servoleads,regulatorsetc.

The AR7600 has a minimum operational voltage o 3.5 volts; it is highly recommended thepower system be tested per the guidelines below and in the Flight Log section.

RecommendedPowerSystemTestGuidelinesI a questionable power system is being used (e.g. small or old battery, ESC that may not havea BEC that will support high-current draw, etc.), it is recommended that a voltmeter be used to

perorm the ollowing test.Note: The Hangar 9 Digital Servo & Rx Current Meter (HAN172) or the Spektrum Flight Log

(SPM9540) are the perect tools to perorm the test below.

Plug the voltmeter into an open channel port in the receiver and with the system on, load thecontrol suraces (apply pressure with your hand) while monitoring the voltage at the receiver.The voltage should remain above 4.8 volts even when all servos are heavily loaded.

Note: The latest generations o Nickel-Metal Hydride batteries incorporate a new chemistrymandated to be more environmentally riendly. These batteries when charged with peakdetection ast chargers have tendencies to alse peak (not ully charge) repeatedly. Theseinclude all brands o NiMH batteries. I using NiMH packs, be especially cautious whencharging, making absolutely sure that the battery is ully charged. It is recommended touse a charger that can display total charge capacity. Note the number o mAh put into adischarged pack to veriy it has been charged to ull capacity.

FlightLog(SPM9540Optional)

The Flight Log is compatible with the AR7600. The Flight Log displays overall RF linkperormance as well as the individual internal and external receiver link data. Additdisplays receiver voltage.

UsingtheFlightLogAter a fight and beore turning o the receiver or transmitter, plug the Flight Log inport on the AR7600. The screen will automatically display voltage e.g. 6v2= 6.2 volt

Note: When the voltage reaches 4.8 volts or less, the screen will fash indicating

Press the button to display the ollowing inormation:A - Antenna ades on the internal antennaB Not usedL Antenna ades on the external antennaR Not usedF - Frame lossH - Holds

Antenna adesrepresents the loss o a bit o inormation on that specic antennaTypically its normal to have as many as 50 to 100 antenna ades during a fight. I aantenna experiences over 500 ades in a single fight, the antenna should be reposit

Frame lossrepresents simultaneous antenna ades on all attached receivers. I this perorming optimally, rame losses per fight should be less than 20. A hold occursconsecutive rame losses occur. This takes about one second. I a hold occurs duringimportant to evaluate the system, moving the antennas to dierent locations and/orbe sure the transmitter and receivers are all working correctly.

Note: A servo extension can be used to allow the Flight Log to be plugged in morconveniently. On some models, the Flight Log can be plugged in, attached the model using double-sided tape. Mounting the Flight Log conveniently torame is common with helicopters.

ModelMatchSome Spektrum and JR transmitters oer a patent pending eature called ModelMaModelMatch prevents the possibility o operating a model using the wrong model mpotentially preventing a crash. With ModelMatch each model memory has its own u(GUID) and during the binding process the code is programmed into the receiver. Latsystem is turned on, the receiver will only connect to the transmitter i the corresponmemory is programmed on screen.

Note: I at any time you turn on the system and it ails to connect, check to be sucorrect model memory is selected in the transmitter. Please note that the S

Aircrat Modules do not have ModelMatch.

Tips on Using Spektrum 2.4GHzWhileyourDSMequipped2.4GHzsystemisintuitivetooperate,functioningnearlyidenticallyto72MHzsystems,followingareafewcommonquestionsfromcustomers.

Q:WhichdoIturnonrst,thetransmitterorthereceiver?

A: I the receiver is turned o frstall servos except or the throttle will be driven to theirpreset ailsae positions set during binding. At this time the throttle channel doesnt output apulse position preventing the arming o electronic speed controllers or in the case o an enginepowered aircrat the throttle servo remaining in its current position. When the transmitter isthenturnedonthetransmitterscansthe2.4GHzbandandacquirestwoopenchannels.Thenthe receiver that was previously bound to the transmitter scans the band and nds the GUID

(Globally Unique Identier code) stored during binding. The system then connects and operatesnormally.

I the transmitter is turned on frstthetransmitterscansthe2.4GHzbandandacquirestwoopen channels. When the receiver is then turned on or a short period (the time it takes toconnect) all servos except or the throttle are driven to their preset ailsae positions while thethrottlehasnooutputpulse.Thereceiverscansthe2.4GHzbandlookingforthepreviouslystored GUID and when it locates the specic GUID code and conrms uncorrupted repeatablepacket inormation, the system connects and normal operation takes place. Typically this takes2 to 6 seconds.

Q:Sometimesthesystemtakeslongertoconnectandsometimesitdoesntconnect atall?

A: In order or the system to connect (ater the receiver is bound) the receiver must receivea large number o consecutive uninterrupted perect packets rom the transmitter in order toconnect. This process is purposely critical o the environment ensuring that its sae to fy whenthe system does connect. I the transmitter is too close to the receiver (less than 4 eet) or i thetransmitter is located near metal objects (metal TX case, the bed o a truck, the top o a metalwork bench, etc.) connection will take longer and in some cases connection will not occur as

thesystemisreceivingreected2.4GHzenergyfromitselfandisinterpretingthisasunfriendlynoise. Moving the system away rom metal objects or moving the transmitter away rom thereceiver and powering the system again will cause a connection to occur. This only happensduring the initial connection. Once connected the system is locked in and should a loss o signaloccur (ailsae) the system connects immediately (4ms) when signal is regained.

Q:IveheardthattheDSMsystemislesstolerantoflowvoltage.Isthiscorrect?

A: All DSM receivers have an operational voltage range o 3.5 to 9.6 volts. With most systemsthis is not a problem as in act most servos cease to operate at around 3.8 volts. When usingmultiple high-current draw servos with a single or inadequate battery/power source, heavymomentary loads can cause the voltage to dip below this 3.5-volt threshold thus causing theentire system (servos and receiver) to brown out. When the voltage drops below the low voltagethreshold (3.5 volts), the DSM receiver must reboot (go through the start-up process o scanningthe band and nding the transmitter) and this can take several seconds. Please read the receiverpower requirement section as this explains how to test or and prevent this occurrence.

Q:Sometimesmyreceiverlosesitsbindandwontconnectrequiringrebinding.Whathappensifthebindislostinight?

A: The receiver will never lose its bind unless its instructed to. Its important to understand thatduring the binding process the receiver not only learns the GUID (code) o the transmitter but thetransmitter learns and stores the type o receiver that its bound to. I the transmitter is placedinto bind mode, the transmitter looks or the binding protocol signal rom a receiver. I no signalis present, the transmitter no longer has the correct inormation to connect to a specicreceiver and in essence the transmitter has been unbound rom the receiver. Weve hadseveral DX7 customers that use transmitter stands or trays that unknowingly depress thebind button and the system is then turned on losing the necessary inormation to allow theconnection to take place. Weve also had DX7 customers that didnt ully understand the rangetest process and pushed the bind button beore turning on the transmitter also causing thesystem to lose its bind.
