Receiver Installation

Airplanes with signicant carbon ber construction can create an RF shielding effect,

reducing range. The AR6255 is designed to overcome these critical RF issues in carbon airplanes by outﬁtting the aircraft with two external antennas at speciﬁc points that will ensure secure RF coverage from all angles of the aircraft.

Feeder Antennas

The AR6255 incorporates two feeder antennas, which are designed to be easily mounted through the fuselage in carbon airplanes. The receiver has two 4-inch feeder antennas. Each feeder antenna includes a coaxial portion (which can be thought of as an extension) and an exposed 31mm tip antenna. The last 31mm is the

active portion of the antenna.

Red LED Hold Indicator

The AR6255 features a red LED (labeled with H) that indicates the number of holds that have occurred since the receiver was last powered on. The LED will ash the number of holds then pause (e.g., ash, ash, ash, pause, ash, ash, ash, pause indicates three holds occurred since the receiver was last turned on). Note that holds are reset to zero when the receiver is turned off. During the rst ights of a new airplane, it’s recommended to check the red LED hold indicator. If it’s ashing, it’s important to optimize the installation (move or reposition antennas) until no hold occurs. On later ights, the LED Hold Indicator can be used to conrm RF link

performance.

Step 1. Identifying the Type of Carbon Aircraft

While some Hand Launch Gliders and F5D airplanes are full carbon construction,

many only use carbon in areas that require extra strength. Some of the latest

aircraft are constructed with 2.4GHz friendly fuselages, meaning that the forward

section of the fuselage is constructed from non-conductive materials like ﬁberglass and Kevlar that don’t affect RF. The ﬁrst step in a proper installation is identifying the type of fuselage.

A- Full Carbon

All components of the airplane including the entire fuselage, the wing and tail are

constructed of carbon ﬁber or have a carbon ﬁber weave throughout the aircraft.

External Antennas

Full Carbon

B- 2.4GHz Friendly Fuselage The section forward of the wing is constructed of non-conductive materials like

berglass, Kevlar, etc. but the wing and possibly the tail section have carbon or

carbon weave construction.

Internal Antennas

Step 2. Determining Antenna Mounting Positions

After determining which type of aircraft from the list above, use the above illustrations as a guideline as to where the feeder antennas should be mounted. Note that full carbon aircraft requires externally mounted antennas while the 2.4GHz-

friendly fuselage can have the antennas mounted internally. The goal is to mount the antennas in a location so that at least one will always be in the RF visual line of sight

of the transmitter (e.g. not blocked by carbon ber structures) in all attitudes. This can easily be visualized by having a helper stand about 20 feet away and rotate the

airplane in all attitudes conﬁrming that in all positions there is a direct line between you and at least one receiver antenna that isn’t blocked by carbon ﬁber structure.

Step 3. Installing the Receivers

Install the receiver in the normal position recommended by the

airplane’s manufacturer. Double-sided tape or foam can be used to secure the main receiver in place.

Step 4. Mounting the Antennas

To install the antennas, drill a 1/16-inch hole in the desired antenna mounting

position.

Slide the feeder antenna through the hole until the 31mm tip, and about 2mm of coaxial, completely exit the fuselage. Using a drop of CA, glue the antenna to

the fuselage making sure that the 31mm active portion of the antenna tip is fully exposed.

2.4GHz Friendly

Note: If the antenna is to be mounted internally (in the front of a 2.4GHz fuse), the

coaxial can be taped into position. Be sure the 31mm tip is located at least 2 inches from any signiﬁcant carbon structure.

Step 5. Plugging in the Servo Leads

Plug the servo leads into the appropriate servo ports in the receiver, noting the

polarity of the servo connector. Consult your radio’s manual for speciﬁc details as to which servo plugs into which servo port channel.

Step 6. Binding the Receiver The AR6255 must be bound to the transmitter before it will operate. Binding is the process of teaching the receiver the speciﬁc code of the transmitter so it will only connect to that speciﬁc transmitter.

1. To bind an AR6255 to a DSM2 transmitter, insert the bind plug in the BIND/

DATA port on the receiver.

2. Power the receiver through any other port. Note that the orange LED on the

receiver should be ashing, indicating that the receiver is in bind mode and

ready to be bound to the transmitter.

3. Move the sticks and switches on the transmitter to the desired failsafe positions

for the throttle, elevator and aileron channels.

4. Follow the procedures of your specic transmitter to enter Bind Mode; the

system will connect within a few seconds. Once connected, the orange LED on

the receiver will go solid indicating the system is connected.

5. Remove the bind plug from the BATT/BIND port on the receiver before you

power off the transmitter and store it in a convenient place.

IMPORTANT: Remove the bind plug to prevent the system from entering bind

mode the next time the power is turned on.

Step 7. Radio Setup and Programming

Following the instructions in your radio manual, program your airplane.

Step 8. Rebinding the Receiver

After you’ve programmed your model, it’s important to rebind the system so the true

failsafe control surface positions are set.

Step 9. Ground Range Testing and Veriﬁcation Red LED Advanced Range Testing

In airplanes that have signicant carbon ber construction, it is imperative to rst

do an advanced ground range check. This ground range check will conﬁrm that the receiver is operating optimally and that the antennas are properly mounted in a position that will give positive RF coverage in all attitudes. This advanced range check allows the RF performance of the receiver and the positions of each antenna to

be veried and to optimize the locations of the antennas.

Advanced Range Test

1. Turn on the system (Tx and Rx).

2. Have a helper hold your aircraft while observing the red LED (labeled with H)

located on the receiver.

3. Standing 30 paces away from the model, face the model with the transmitter in

your normal ying position and put your transmitter into range test mode. This

causes reduced power output from the transmitter.

4. Have your helper position the model covering all orientations (nose up, nose

down, nose toward the Tx, nose away from the Tx, etc.) while watching the red LED, noting any correlation between the aircraft’s orientation and when holds

occur. Do this for one minute. The timer on the transmitter can be used here.

5. After one minute, release the range test button. A successful installation will

yield the following: no holds, no ashing red LED.

If any holds occur redo the test, noting the orientation of the aircraft when the holds occur. This will allow you to change and optimize the antenna position(s) to a better

location.

Step 10. Short Test Flight Veriﬁcation with Hold Indicator

When the system tests successfully, it’s time for a short near test ight. This rst ight should be close (in less than 200 feet) and about ve minutes or less. After the ight, land near yourself and check that no holds occurred. A successful ight will result in 0 holds. Extend the ight distance and times, checking the Hold data after every ight until you are condent with the results.

IMPORTANT: Y-Harnesses and Servo Extensions When using Y-harness or servo extensions, it’s important to use standard nonamplied Y-harnesses and servo extensions as they can/will cause the servos to

operate erratically or not function at all. Ampliﬁed Y-harnesses were developed

several years ago to boost the signal for some older PCM systems and should not be used with Spektrum equipment. Note that when converting an existing model to Spektrum, be certain that all amplied Y-harnesses and/or servo extensions are

replaced with conventional non-ampliﬁed versions.

Preset Failsafe

The AR6255 features preset failsafe on all channels. Preset failsafe is ideal for sailplanes, allowing the aircraft to automatically dethermalize if the signal is lost. With preset failsafe, all channels will go to their preset failsafe positions if the signal is lost, preventing a yaway.

Receiver Power Only

• When the receiver only is turned on (no transmitter signal is present), all channels have no output signal, to avoid overdriving the servos and linkages.

Note: Some analog servos may drift slightly during power-up even though no

signal is present. This is normal.

After Connection

• When the transmitter is turned on and after the receiver connects to the transmitter, normal control of all channels occurs.

• After the system makes a connection, if loss of signal occurs Preset Failsafe drives the throttle, aileron and elevator servos to their preset failsafe position set

during binding.

Receiver Power System Requirements

Inadequate power systems that are unable to provide the necessary minimum voltage to the receiver during ight have become the number one cause of in-ight

failures. Some of the power system components that affect the ability to properly deliver adequate power include:

• Receiver battery pack (number of cells, capacity, cell type, state of charge)

• The switch harness, battery leads, servo leads, regulators, etc.

• The BEC used in the speed controller won’t support the current required by the

servos.

The AR6255 has a minimum operational voltage of 3.5 volts; it is highly

recommended the power system be tested per the guidelines below.

Recommended Power System Test Guidelines

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

perform the following test.

Note: The Spektrum Flight Log (SPM9540) is the perfect tool to monitor voltage

in the test below.

Plug the Flight Log into an open channel port in the receiver and with the system on, load the control surfaces (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 of Nickel-Metal Hydride batteries incorporate a new

chemistry mandated to be more environmentally friendly. These batteries, when charged with peak detection fast chargers, have tendencies to false peak (not fully charge) repeatedly. These include all brands of NiMH batteries. If using NiMH packs, be especially cautious when charging, making absolutely sure that the battery is fully charged. It is recommended to use a charger that can display total charge capacity. Note the number

of mAh put into a discharged pack to verify it has been charged to full capacity.

QuickConnect™ With Brownout Detection

Your AR6255 features QuickConnect with Brownout Detection.

• Should an interruption of power occur (brownout), the system will reconnect immediately when power is restored (QuickConnect).

• The orange LED on the receiver will ash slowly indicating a power interruption (brownout) has occurred.

• Brownouts can be caused by an inadequate power supply (weak battery or regulator), a loose connector, a bad switch, an inadequate BEC when using an electronic speed controller, etc.

• Brownouts occur when the receiver voltage drops below 3.5 volts thus

interrupting control as the servos and receiver require a minimum of 3.5 volts to operate.

How QuickConnect With Brownout Detection Works

• When the receiver voltage drops below 3.5 volts the system drops out (ceases to operate).

• When power is restored the receiver immediately attempts to reconnect to the

last two frequencies that it was connected to.

• If the two frequencies are present (the transmitter was left on) the system

reconnects typically in about a fraction of a second.

QuickConnect with Brownout Detection is designed to allow you to y safely through most short-duration power interruptions; however, the root cause of these interruptions must be corrected before the next ight to prevent catastrophic safety

issues.

Note: If a brownout occurs in ight, it is vital that the cause of the brownout be

determined and corrected.

Flight Log (SPM9540 Optional)

The Flight Log is compatible with the AR6255. The Flight Log displays overall RF

link performance as well as the individual internal and external receiver link data. Additionally it displays receiver voltage.

Using the Flight Log

After a ight and before turning off the receiver or transmitter, plug the Flight Log into

the Data port on the AR6255. The screen will automatically display voltage e.g. 6v2=

6.2 volts.

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

low voltage.

Press the button to display the following information: A - Antenna fades on the internal antenna

B – Not used L – Antenna fades on the external antenna R – Not used

F - Frame loss

H - Holds

Antenna fades—represents the loss of a bit of information on that speciﬁc antenna.

Typically it’s normal to have as many as 50 to 100 antenna fades during a ight. If any single antenna experiences over 500 fades in a single ight, the antenna should be repositioned in the aircraft to optimize the RF link.

Frame loss—represents simultaneous antenna fades on all attached receivers.

If the RF link is performing optimally, frame losses per ight should be less than

20. A hold occurs when 45 consecutive frame losses occur. This takes about one

second. If a hold occurs during a ight, it’s important to evaluate the system, moving the antennas to different locations and/or checking to be 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 more conveniently. On some models, the Flight Log can be plugged in, attached and left on the model using double-sided tape. Mounting the Flight Log conveniently to the side

frame is common with helicopters.

ModelMatch™

Some Spektrum and JR transmitters offer a feature called ModelMatch that prevents

the possibility of operating a model using the wrong model memory, potentially preventing a crash. With ModelMatch, each model memory has its own unique code (GUID) and during the binding process the code is programmed into the receiver. Later, when the system is turned on, the receiver will only connect to the transmitter

if the corresponding model memory is programmed onscreen.

Note: If at any time you turn on the system and it fails to connect, check to be

sure the correct model memory is selected in the transmitter. Please note

that the Spektrum Aircraft Modules do not have ModelMatch.

Tips On Using 2.4GHz

While your DSM equipped 2.4GHz system is intuitive to operate, functioning nearly identically to 72MHz systems, following are a few common questions from

customers.

1. Q: Which do I turn on rst, the transmitter or the receiver?

A: If the receiver is turned on rst—all channels have no output pulses. When

the transmitter is then turned on, the transmitter scans the 2.4GHz band and

acquires two open channels. Then the receiver that was previously bound to the

transmitter scans the band and nds the GUID (Globally Unique Identier code)

stored during binding. The system then connects and operates normally.

If the transmitter is turned on rst—the transmitter scans the 2.4GHz band and

acquires two open channels. When the receiver is then turned on for a short

period (the time it takes to connect) all channels have no output pulses. The

receiver scans the 2.4GHz band looking for the previously stored GUID. When it locates the specic GUID code, it conrms the uncorrupted repeatable packet information, the system connects and normal operation takes place. Typically

this takes 2 to 6 seconds.

2. Q: Sometimes the system takes longer to connect and sometimes it doesn’t connect at all?

A: In order for the system to connect (after the receiver is bound) the receiver must

receive a large number of consecutive uninterrupted perfect packets from the transmitter. This process is purposely critical of the environment ensuring that

it’s safe to y when the system does connect. If the transmitter is too close to the receiver (less than 4 feet) or if the transmitter is located near metal objects (metal Tx case, the bed of a truck, the top of a metal work bench, etc.),

connection will take longer and in some cases connection will not occur as the

system is receiving reected 2.4GHz energy from itself and is interpreting this

as unfriendly noise. Moving the system away from metal objects or moving the transmitter away from the receiver and powering the system again will cause

a connection to occur. This only happens during the initial connection. Once connected, the system is locked in and should a loss of signal occur (failsafe),

the system connects immediately when the signal is regained.

3. Q: I’ve heard that the DSM system is less tolerant of low voltage. Is this correct?

A: All DSM receivers have an operational voltage range of 3.5 to 9.6 volts. With

most systems this is not a problem as, in fact, most servos cease to operate at

around 3.8 volts. When using multiple high-current draw servos with a single

or inadequate battery/ power source, heavy momentary loads can cause the

voltage to dip below this 3.5-volt threshold thus causing the entire system

(servos and receiver) to brown out. When the voltage drops below the low voltage threshold (3.5 volts), the DSM receiver must reboot (go through the startup process of scanning the band and nding the transmitter) and this can take several seconds. Please read the receiver power requirement section as

this explains how to test for and prevent this occurrence.

4. Q: Sometimes my receiver loses its bind and won’t connect requiring rebinding. What happens if the bind is lost in ight?

A: The receiver will never lose its bind unless it’s instructed to. It’s important to

understand that during the binding process the receiver not only learns the

GUID (code) of the transmitter, but the transmitter learns and stores the type of receiver that it’s bound to. If the transmitter is placed into bind mode, the transmitter looks for the binding protocol signal from a receiver. If no signal is present, the transmitter no longer has the correct information to connect to

a speciﬁc receiver and in essence the transmitter has been “unbound” from the receiver. We’ve had several DX7 customers that use transmitter stands or trays

that unknowingly depress the bind button and the system is then turned on,

losing the necessary information to allow the connection to take place. We’ve also had DX7 customers that didn’t fully understand the range test process and pushed the bind button before turning on the transmitter also causing the system to “lose its bind.”

Der AR6255 ist mit einer roten Leuchtdiode ausgestattet (gekennzeichnet mit einem H), die die Anzahl der Holds seit dem letzten Einschalten anzeigt Die LED blinkt und zeigt dabei die Anzahl der Holds, danach erfolgt eine Pause. Beispiel: blink, blink, blink, Pause, blink, blink, blink. Hier zeigt der Empfänger 3 Holds seit dem letzten Einschalten. Bitte beachten Sie, dass dieser Speicher mit dem Ausschal-ten gelöscht wird. Wir raten an, während erster Flüge mit einem neuen Modell die LED auf Blinken zu kontrollieren. Sollte ein Blinken auftreten, optimieren Sie die Position des Empfängers oder der Antennen bis kein Blinken mehr auftritt. Bei späteren Flügen kann der LED Hold Indikator als für die Empfangleistung angesehen werden.

Schritt 1: Identiﬁzieren des Carbon im Flugzeug

Es gibt Hand Launch Glider und F5D Flugzeuge, die komplett aus Carbon gefertigt sind und es gibt andere Typen, die Carbon nur an besonders belasteten Stellen verwenden. Einige der neuesten Typen haben eine 2.4 GHz freundliche Konstruktion, wo der vordere Rumpfbereich aus Fiberglas oder Kevlar besteht, die die Funkwellen nicht negativ beein¬ussen. Der erste Schritt für einen richtigen Einbau ist das Erkennen des Rumpftypes.
