DSMX

Spektrum launched the 2.4GHz RC revolution with its DSM2 technology. Since
then millions of hobbyists the world over have come to embrace 2.4 as the way
to fly. Spektrum leads the way yet again with DSMX; the world’s first wideband,
frequency-agile 2.4GHz signal protocol.

HOW DOES DSMX WORK?

It’s a crowded 2.4GHz world out there and every 2.4GHz system faces the same
challenges. DSMX better equips you for these challenges by combining the
superior data capacity and interfer¬ence resistance of a wideband signal (like
that used in DSM2) with the agility of frequency shifts.

Compared to the wideband signal of DSMX, the narrow band signal of other
frequency hopping 2.4 transmitters is more likely to suffer data loss in the event
of on-channel interference. Think of it as a river vs. a stream. It takes more
interference to dam a river than it does a stream.

As more and more 2.4 transmitters vie for the same number of available
channels, there is more interference and more of a risk for data loss. By
adding the agility of frequency shifts to the superior interference resistance of
a wideband signal, DSMX is far less likely to suffer significant data loss from
on-channel interference. The result is quicker connection times and superior
response in even the most crowded 2.4GHz environment.

DSMX OPERATIONAL DIFFERENCES

DSMX transmitters and receivers function nearly identically to Spektrum DSM2
systems. Binding, setting the failsafe, recording flight log data, as well as general
use of the system is no different than using any current Spektrum system.

FOLLOWING ARE THE OPERATIONAL DIFFERENCES:

Brownout Detection- Not Available on DSMX Receivers

DSM2 receivers feature Brownout Detection that flashes the receiver’s LED if
a power interruption occurs. While DSMX receivers have QuickConnect and
recover instantly from a power interruption, the architecture of DSMX prevents
Brownout Detection when operating in DSMX mode.

FLIGHT LOG RECORDING-FADES HIGHER THAN DSM2

Note that DSMX hops through the band while DSM2 finds two quiet channels
and remains on those channels. Consequently because DSMX operates on
quiet and noisy channels, it’s common to have more Antenna Fades than when
using DSM2, when used in busy 2.4GHz environments. When taking flight log
data readings, the Frames and Hold Data are important and should be used a
reference while Fades are insignificant due to the nature of frequency hopping. A
10-minute flight will typically result in less than 50 Frame Losses and no Holds.

JUST HOW GOOD IS DSMX?

In multiple tests, 100 DSMX systems were operated simultaneously for extended
periods of time. During these tests each of the 100 systems was monitored in
flight and on the ground. In every test not a single case of RF link loss, latency
increase or control degradation was experienced or recorded.

IS DSMX COMPATIBLE WITH DSM2?

Yes. DSMX is fully compatible with all DSM2 hardware. In fact, many pilots may
find the DSM2 equipment they have now is all they will ever need. Even if a new
DSMX transmitter eventually comes along that they really want, all the DSM2
receivers they have now will work with it.

It is important to note, however, that while DSMX is compatible with DSM2, the
only way to experience the full benefits of DSMX in a busy 2.4 environment is by
pairing a DSMX transmitter with a DSMX receiver.

CAN DSM2 TRANSMITTERS
BE UPGRADED TO DSMX?

Yes. DX8 owners can simply download Spektrum AirWare™ v2.0 software from
spektrumrc.com and update the firmware using their SD card. DX6i transmitters
manufactured after October 2010 can be upgraded using instructions provided
on spektrumrc.com. All other DX6i DSM2 transmitters can be upgraded for $75
by sending them to the Horizon Hobby service center. DSM2 receivers
and transmitter modules cannot be upgraded to DSMX.

DOES DSMX HAVE
MODELMATCH AND SERVOSYNC?

Yes. DSMX will provide you with these and other exclusive Spektrum advantages
you already enjoy with DSM2. Want to know more about DSMX? Visit
spektrumrc.com for complete details on this as well as the many other
reasons Spektrum is the leader in 2.4.

GENERAL NOTES

Radio controlled models are a great source of pleasure. Unfortunately, they
can also pose a potential hazard if not operated and maintained properly. It
is imperative to install your radio control system correctly. Additionally, your
level of piloting competency must be high enough to ensure that you are able
to control your aircraft under all conditions. If you are a newcomer to radio
controlled flying, please seek help from an experienced pilot or your
local hobby store.

DSMX TECHNOLOGY

DSMX technology can be turned on and off with this transmitter. The default is
for DSMX technology to be turned on. When it is on, the transmitter will bind to
standard DSM2 receivers and DSMX receivers. The only time DSMX technology
must be turned off is to bind to high-speed 11ms 2048 DSM2 receivers.

DSMX ON:

Press and hold the trainer button, and move and hold the sticks as shown below.
Turn on the transmitter, and you will hear a series of beep tones. Then release the
trainer button and the sticks.

DSMX cannot be turned on if France Mode is set. See page 13 for more
information on France Mode.

DSM2 ON:

Press and hold the trainer button, and move and hold the sticks as shown below.
Turn on the transmitter, and you will hear a series of beep tones. Then release the
trainer button and the sticks.

RECEIVER COMPATIBILITY

The DX4e is compatible with all current Spektrum™ and JR® brands of DSM2®
and DSMX aircraft receivers.

CAUTION: When using the DX4e with park flyer receivers (the

AR6115, AR6115e, etc.), it’s imperative that these receivers only be flown
in park flyer-type aircraft (small electric airplanes or mini and micro
helicopters). Flying receivers designed for park flyers in larger aircraft could
cause loss of connection.

EN

Note: The DX4e is NOT compatible with the original DSM AR6000 receiver.

9

Note: The DSMX DX5e is compatible with all current Spektrum DSM2
and DSMX aircraft receivers, but NOT compatible with the original DSM
AR6000 receiver. For current receiver compatibility information, go to
www.spektrumrc.com.

INSTALLING THE TRANSMITTER BATTERIES

The DX4e requires 4 AA alkaline, heavy-duty or rechargeable batteries.

BATTERY INSTALLATION

Remove the battery door and install 4 AA batteries. Make sure the polarity of each
corresponds with the diagram in the battery holder. Replace the battery door.

LOW BATTERY ALARM

When the battery voltage drops below 4.7 volts, an alarm sounds and the voltage
LEDs flash. The batteries must be replaced immediately. If this happens while
flying, land your aircraft as soon and as safely as possible.

TRAINER

The DX4e offers a trainer function that allows the transmitter to operate as a
master or slave. The trainer button is located on the left shoulder of the mode
2/4 transmitters and on the right shoulder of the mode 1/3 transmitters. When
using the trainer function, plug the trainer cord (SPM6805) into the trainer port
in both the master (instructor) and the slave (student) transmitters. The master
transmitter must have the power turned on. The slave transmitter must have the
power turned off. When you press and hold the trainer button on the master, it
gives control authority to the slave. When you release the trainer button, control
returns to the master.

Note: The DX4e trainer system is compatible with all JR (excluding the
JR S400) and Spektrum aircraft transmitters that feature trainer ports.

MASTER/SLAVE

The slave transmitter must always have the same reverse settings as the master.

BINDING

The receiver must be bound to the transmitter before operating. Binding
teaches the transmitter’s specific code to the receiver so it only connects to
that transmitter. These instructions explain how to bind most Spektrum aircraft
receivers. Some receivers, such as the AR6400 series receivers, have different
binding methods. Please check the manual for your receiver for the proper
binding procedure.

EN

10

1. To bind a receiver, insert the bind plug in the BIND/DATA port.

Note: To bind an aircraft with an electronic speed controller that powers the
receiver through the throttle channel (ESC/BEC), insert the bind plug into
the BIND/DATA port in the receiver and the throttle lead into the throttle port.
Proceed to Step #2.

Shown above using a separate receiver pack

Note: When binding using a switch harness and separate receiver pack, you

must use a three-wire switch harness such as SPM9530 (not shown). In
addition, you may need to purchase the Male/Female bind plug SPM6803.

2. Power the receiver by plugging in a receiver battery in any port on the
receiver. The LED on the receiver will flash. The receiver is ready to be
bound to the transmitter.

EN

Shown above using an ESC/BEC and a flight pack

3. Move the sticks and switches on the transmitter to the desired failsafe
positions (low throttle and neutral control positions).

11

5. Remove the bind plug from the BIND/DATA port on the receiver before you
power off the receiver. Store the plug in a convenient place.

6. After setting up your model, rebind the system so the true low throttle and
neutral control surface positions are programmed.

4. Press and hold the trainer button on the top of the transmitter while turning
on the power switch. Release the trainer button once the LEDs on the front
of the transmitter flash and you hear a series of beeps. Within a few seconds
the system should connect. Once connected, the LED on the receiver will go
solid indicating the system is connected.

CAUTION: Continuing to hold the trainer button during the binding

process prevents preset failsafe positions from being learned by the receiver.

HOW TO RANGE TEST THE DX4E

Before each flying session, and with a new model, you should perform a range
check. The DX4e incorporates a range testing system. Placing the transmitter in

SERVO REVERSING

The DX4e features servo reversing on channels 1–4. The switches are located
at the lower front of the transmitter. They are used to select the servo direction
of each channel. Use your fingernail or a small screwdriver to change the switch
position to normal (NOR) or reverse (REV).

ELEVON/ DELTA MIXING

The DX4e offers an Elevon mix. Elevon (also called delta wing) mixing combines
the function of ailerons with the function of the elevator to allow precise control
of both roll and pitch for delta wing aircraft. To activate the Elevon mix, move the
mix switch to the on (up) position.

FRANCE RF SETTING

TO SET FRANCE MODE:

Push and hold the trainer button on the top of the transmitter while pushing and
holding the two sticks as shown below, then turn on the power switch.

After hearing a series of descending beep tones, release the trainer switch and
the sticks. The France setting is now turned on.

Bind the transmitter to the receiver for the change to take effect. See page 9 for
binding instructions.

EN

14

TO SET STANDARD MODE:

Push and hold the trainer button on the top of the transmitter while pushing and
holding the two sticks as shown below, then turn on the power switch.

After hearing a series of ascending beep tones, release the trainer switch and the
sticks. The France setting is now turned off.

ACT/AUX

The ACT/Aux switch is for use with HobbyZone planes equipped with Anti­Crash Technology (ACT) or planes that require an auxiliary function. For more
information about ACT, please refer to the manual of your HobbyZone plane.

HI/LO RATE

The DX4e offers a high/low rate function on aileron, elevator and rudder. When
the HI/LO rate switch is in the upper position, or “HI” position, 100% travel is
achieved on the aileron, elevator and rudder channels. When the switch is in
the lower, or “LO”, position, a reduced travel of 70% is achieved on the aileron,
elevator and rudder channels. This allows the aircraft to have a high control rate
(switch to the “HI” position) for aggressive maneuvers and a low control rate
(switch to the “LO” position) for smooth, precise maneuvers.

You might notice a very slight movement in the aileron, elevator and rudder
position when you change rates. This is due to the style of trim switches on the
DX4e and the amount of trim you have set on each channel. To minimize the
movement, mechanically adjust the linkages on your aircraft so the trims are as
close to center as possible.

EN

RECEIVER POWER SYSTEM REQUIREMENTS

The onboard power system must provide adequate power without interruption
to the receiver even when the system is fully loaded (servos at maximum flight
loads). Inadequate power systems that do not provide the necessary minimum

15

voltage to the receiver during flight loads are the number-one cause of in­flight failures. Some of the power system components that affect the delivery
of adequate power include: the selected receiver battery pack (number of cells,
capacity, cell type, state of charge), switch harness, battery leads and, if used,
the regulator and power bus.

While a Spektrum receiver’s minimum operational voltage is 3.5 volts, test the
system per the guidelines below to a minimum acceptable voltage of 4.8 volts
during ground testing. This compensates for battery discharging or greater actual
flight loads than ground test loads.

RECOMMENDED POWER SYSTEM
GUIDELINES FOR LARGE PLANES

1. When setting up large or complex aircraft with multiple high-torque servos,
you should use a current and voltmeter (Hangar 9 HAN172). Plug the
voltmeter in an open channel port in the receiver. 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.

2. With the current meter in line with the receiver battery lead, load the control
surfaces (apply pressure with your hand) while monitoring the current. The
maximum continuous recommended current for a single heavy-duty servo/
battery lead is three amps. Short-duration current spikes of up to five amps
are acceptable. If your system draws more than these currents, you need to
use multiple packs (of the same capacity, cell number, cell type and state of
charge) with multiple switches and multiple leads plugged into the receiver.

3. If using a regulator, perform the above tests for a 5-minute period. When
current passes through a regulator, heat is generated. This heat causes
the regulator to increase resistance, causing even more heat to build up

(thermal runaway). While a regulator may provide adequate power for a short
duration, you should test its ability over time as the regulator may not be
able to maintain voltage at significant power levels.

4. For really large aircraft or complex models (for example 35% and larger or
jets), multiple battery packs with multiple switch harnesses are necessary.
In many cases one of the commercially available power boxes/ busses is
recommended. No matter what power system you choose, always carry out
test #1 above. Make sure the receiver is constantly provided with 4.8 volts or
more under all conditions.

5. Nickel-Metal Hydride batteries, when charged with peak detection fast
chargers, have a tendency to false peak (not fully charge) repeatedly.
These include all brands of NiMH batteries. When charging, make sure the
battery is fully charged. You should use a charger that displays total charge
capacity. Note the number of mAh put into a discharged pack to verify it has
been charged to full capacity.

FREQUENTLY ASKED QUESTIONS
ON USING 2.4GHZ SYSTEMS

1. Q: After I’ve bound the receiver to my transmitter, which do I turn on first
when I want to fly?

A: Either one, unless you are using a Smart Bind receiver such as the

AR6400 or AR6400L. With a Smart Bind receiver, the transmitter must be
turned on approximately 5 seconds before the receiver.

2. Q: Sometimes the system takes longer to connect or doesn’t connect at all.
Why?

EN

16

A: In order for a DSM system to connect, the receiver must receive a large

number of uninterrupted signal packets from the transmitter. This process
takes just a few seconds, but if the transmitter is too close to the receiver
(within 4 feet) or near reflective material (metal objects, carbon fiber
materials, tuned pipes, etc.) it may detect its own reflected 2.4GHz energy as
“noise”. This can delay or prevent connection.

If this happens make sure you are a sufficient distance from metal objects

and the receiver itself before you power up and try again.

3. Q: Is it true that DSM systems are less tolerant of low voltage?
A: All DSM receivers require at least 3.5V to operate normally. Most servos

cease to operate below 3.8V. Using multiple high-voltage servos, however,
with an inadequate power supply can allow voltage to momentarily drop
below 3.5V. This will cause the receiver to “brown out” and reconnect.

All recently manufactured JR and Spektrum DSM receivers feature

QuickConnect technology that will reconnect the system within a quarter of
a second after battery power recovery should a brownout occur. For more
information about Brownout Alert and QuickConnect, please refer to the
instruction manual for your receiver.

4. Q: Sometimes when I power on my DSM system I notice the receiver won’t
connect and it needs to be rebound to the transmitter. Can this happen in
flight?

A: No. A DSM receiver cannot be unbound from its transmitter without

specific action by the user. You can accidentally unbind a receiver by
inadvertently placing the transmitter into bind mode. If this happens and the
transmitter doesn’t detect a binding signal from the receiver it can cause the
receiver to be unbound.

5. Q: How important is it that I test my system using a Spektrum Flight Log?

A: All 2.4GHz signals, not just DSM, are affected by proximity to conductive

materials such as carbon fiber or metal. Few RTF and ARF sport airplanes
or helicopters use enough of these kinds of materials for it to be an issue.
If, however, you’re flying a sophisticated model that uses a lot of conductive
materials in its construction, a Flight Log can be helpful. The information it
collects when you fly will help you determine the optimum location for your
receiver(s) so you can minimize the effects of these materials on your signal
performance. For more details on the Flight Log and how it works, visit
SpektrumRC.com.

FEDERAL AVIATION ADMINISTRATION

PURPOSE

This advisory outlines safety standards for operations of model aircraft. We
encourage voluntary compliance with these standards.

BACKGROUND

Attention has been drawn to the increase in model aircraft operation. There is a
need for added caution when operating free flight and radio controlled craft in
order to avoid creating a noise nuisance or a potential hazard to full-scale aircraft
and persons and/or property on the surface.

OPERATING STANDARDS

Modelers generally are concerned with safety and exercise good judgment
when flying model aircraft. However, in the interest of safer skies, we encourage
operators of radio controlled and free flight models to comply with the following
standards:

EN

17

a. Exercise vigilance in locating full-scale aircraft (get help if possible) so as

not to create a collision hazard.

b. Select an operating site at sufficient distance from populated areas so you do

not create a noise problem or a potential hazard.

c. Do not fly higher than 400 feet above the surface.
d. Always operate more than three miles from the boundary of an airport unless

you are given permission to be closer by the appropriate air traffic control
facility in the case of an airport for which a control zone has been designated
or by the airport manager in the case of other airports.

e. Do not hesitate to ask for assistance in complying with these guidelines at

the airport traffic control tower or air route traffic control center nearest the
site of your proposed operation.

INFORMATION PROVIDED BY

Director, Air Traffic Service Federal Aviation Administration,
Washington, D.C.

DAILY FLIGHT CHECKS

1. Check the battery voltage on both the transmitter and the receiver battery
packs. Do not fly below 4.7V on the transmitter or below 4.7V on the
receiver. To do so can crash your aircraft.

Note: When you check these batteries, ensure that you have the polarities
correct on your expanded scale voltmeter.

2. Check all hardware (linkages, screws, nuts, and bolts) prior to each day’s
flight. Be sure that binding does not occur and that all parts are properly
secured.

3. Ensure that all surfaces are moving in the proper manner.

4. Perform a ground range check before each day’s flying session.

5. Prior to starting your aircraft, turn off your transmitter, then turn it back
on. Do this each time you start your aircraft. If any critical switches are on
without your knowledge, the transmitter alarm will warn you at this time.
This will also confirm the failsafe position settings.

6. Check that all trim levers are in the proper location.

7. All servo pigtails and switch harness plugs should be secured in the
receiver. Make sure that the switch harness moves freely in both directions.

DSMX

Spektrum hat die RC Technologie mit dem DSM2 System revolutioniert und
damit Millionen von RC Hobbyfreunden zu zufriedenen Nutzern des 2.4 Ghz
Systems gemacht.

Spektrum setzt jetzt mit dem DSMX System wieder Meilensteine. DSMX ist
weltweit das erste Breitband Frequenz agile 2.4 Ghz Signalprotokoll.

WIE ARBEITET DSMX ?

Die Nutzer des 2.4 GHz Frequenzbereich werden immer mehr und durch diese
Menge steht jedes System vor der Herrausforderung auch in Zukunft eine sichere
Übertragung zu gewährleisten. Das DSMX ist für diese Herausforderungen
besser gewappnet, kombiniert es die excellente Datenkapazität und Sicherheit
vor Störungen eines Breitbandsignales (wie bei DSM2) genutzt mit der
Frequenzagilität.

Verglichen mit dem Breitbandsignal des DSMX neigen die Signale anderer
Frequenzhoppingsysteme dazu Daten bei Kanalstörungen zu verlieren. Stellen
Sie sich einfach das DSMX System wie einen breiten mächtigen Fluss vor und
die Frequenzhoppingsysteme wie einen Bach. Es braucht erheblich mehr Einfluß
einen großen Strom zu stören als einen Bach.

Die Zahl der Nutzer der 2.4Ghz Systeme steigt ständig bei gleichbleibender
Zahl der zur Verfügung stehender Kanäle. Daraus ergibt sich ein höheres Risiko
für Datenverluste. Zusammen mit der Frequenzagilität und der hervorragenden
Störsicherheit des Breitbandsignales ist das DSMX System die sicherste Wahl.
Weitere Vorteile des Systems sind schnelle Verbindungszeiten und excellente
Resonanz auch in dichtester 2,4 Ghz Umgebung.

UNTERSCHIEDE IM DSMX BETRIEB

DSMX Sender und Empfänger arbeiten nahezu indentisch wie das Spektrum
DSM2 System. Der Bindevorgang, Einstellen des Failsafe, Aufzeichnen der Flight
Log Daten und der allgemeine Betrieb des Systems mach keinen Unterschied zu
dem bestehenden Spektrum System.

DIE SYSTEMUNTERSCHIEDE

Brownout Detection (Spannungsabfalldetektion):

Diese Funktion steht bei DSMX Empfängern nicht mehr zu Verfügung.

DSM2 Empfänger sind mit einer Brownout Detection ausgestattet ,die eine LED
zur Erkennung des Spannungsabfall blinken läßt. DSMX Empfänger sind mit
der Quick Connect Funktion ausgestattet, die sich unverzüglich nach einer
Stromunterbrechung wieder verbindet. Die Architektur von DSMX verhindert so
den Brownout im DSMX Mode.

FLIGTH LOG AUFZEICHNUNGEN -
MEHR AUSBLENDUNGEN ALS BEI DSM2

Bitte beachten Sie, dass DSMX sich in den Kanälen bewegt, während DSM2 sich
zwei ruhige Kanäle sucht und auf ihnen bleibt. Da DSMX auf beiden Kanaltypen
arbeitet ist es normal, dass es mehr Antennenausblendungen (Fades) gibt. Bei
der Benutzung eines Flight Logs sind die Informationen zu den Frame Losses
und Holds die wichtigen Parameter, Fades sind aufgrund der Natur des Systems
insignifikant. Ein 10 Minuten Flug kann kann typischweise weniger als 50
Frame Losses aufweisen und keine Holds.

WIE GUT IST DSMX ?

In multiplen Tests wurden für einen langen Zeitraum 100 DSMX Systeme
gleichzeitig betrieben. Während der Tests wurde jedes DSMX System im Flug
und am Boden überwacht. In jedem Test wurde kein Verlust der RF Verbindung,
Verringerung der Latenzzeit oder ein Qualitätsverlust der Verbindung
aufgezeichnet.

IST DSMX KOMPATIBEL MIT DSM ?

Ja, DSMX ist voll kompabitel zu DSM2. Viele Piloten haben mit ihrer DSM2
Ausrüstung das gefunden was sie für Ihr Hobby brauchen. Da ist es gut zu
wissen, dass auch ein neuer DSMX Sender mit den vorhandenen DSM2
Empfängern kompatibel ist. Wichtig zu bemerken ist, dass trotz der Kompatibilität
von DSMX zu DSM2 alle Vorteile des DSMX nur dann zum Tragen kommen,
wenn ein DSMX Sender mit einem DMX Empfänger betrieben wird.

KANN EIN DSM2 SENDER ZU EINEM
DSMX SENDER AUFGERÜSTET WERDEN ?

Ja, DX8 Besitzer können Ihre Anlage aufrüsten mit dem Download der Spektrum
Air Ware v2.0 Software von Spektrum RC, die über die SD Karte in die Firmware
der Anlage übertragen wird. DX6i Sender die nach Oktober 2010 hergestellt
wurden, können nach den Anweisungen auf der www.SpektrumRC.com Seite
aufgerüstet werden. Alle anderen Sender können gegen 75 € im Horizon Hobby
Service Center aufgerüstet werden. DSM2 Empfänger und Sendermodule können
nicht auf DSMX aufgerüstet werden.

HAT DSMX
MODELLMATCH UND SERVOSYNC ?

Ja, DSMX hat dieses beiden und andere exklusive Funktionen, die Sie schon mit
Ihrem DSM2 System schätzen. Wollen Sie mehr über DSMX wissen? Besuchen
Sie spektrumrc.com für alle Details und viele andere Gründe warum Spektrum
führend im Bereich 2.4 Ghz ist.

Hinweis: Das DSMX System erlaubt es mehr als 40 Sender gleichzeitig zu
betreiben. Sollten Sie jedoch DSM2 Empfänger, DSMX Empfänger im DSM2
Mode oder Sender im DSM2 Mode betreiben, sollten nicht mehr als 40 Sender
gleichzeitig betrieben werden.

DX4E--KANAL-DSM™-SENDER VON SPEKTRUM
MIT VOLLER REICHWEITE

Der Spektrum DX4e-4-Kanal-Sender mit 2,4 GHz DSM-Technologie bietet
Reichweiten über die Sichtweite hinaus und ist besonders für Flugmodelle
mit elektrischem Antrieb und Glühzündermotoren mit 4 oder weniger Kanälen
geeignet. Der DX4e verwendet die DuaLink®-Technologie. Diese Technologie
ist nahezu unempfindlich gegenüber interne und externe Funkstörungen.
KeinePins. Keine Störungen. Die DSM-Technologie von Spektrum macht
dasFliegenso einfach: startklar, einschalten, losfliegen!
