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

How Does DSMX Work?
DSMX combines the superior data capacity and interference 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 GHz transmitters are 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 GHz 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 technology is far less likely to suffer significant data loss from on­channel 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.

Brownout Detection—Not Available on DSMX Receivers

DSM2 receivers feature Brownout Detection that causes the receiver’s LED to flash
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
DSMX uses frequency shifts 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 in busy 2.4GHz environments. When taking flight log data readings, the
Frames and Hold Data are important and should be used as a reference, while
Fades are insignificant due to the nature of frequency agile systems. A 10-minute
flight will typically result in less than 50 Frame Losses and no Holds.

EN

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.

EN

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, 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 GHz environment is by
pairing a DSMX transmitter with a DSMX receiver.

Are DSM2 Transmitters Eligible for a DSMX Add-on?
Yes. DX8 owners can simply download Spektrum AirWare™ v2.0 software
from spektrumrc.com and update the firmware using their SD card. All DSM2
transmitters, except the DX5e, are eligible for the add-on for $75 by sending them to
the Horizon Hobby service center. DSM2 receivers and transmitter modules are not
eligible for the DSMX add-on.

Does DSMX have ModelMatch™ and ServoSync™ Technology?
Yes. DSMX will provide you with these and other exclusive Spektrum advantages
that 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 GHz.

NOTICE: While DSMX allows you to use more than 40 transmitters simultaneously,
when using DSM2 receivers, DSMX receivers in DSM2 mode or transmitters in
DSM2 mode, do not use more than 40 transmitters simultaneously.

Spektrum AR12200

The Spektrum AR12200 Cockpit is an advanced, 12-channel receiver system
that offers the ultimate solution for powering high-current draw radio systems. It
features a freely programmable gear and door sequencer for up to 6 servos with up
to 12 programmable tasks for retracting the gear and another 12 tasks per servo for
extending the gear.

The Cockpit features an integrated servo matching system for up to 4 different dual
channels, perfect for giant-scale aircraft using ganged servos on a surface. The
Spektrum Cockpit eliminates the need for external voltage regulators, gear door
sequencers, and servo matchers.

In aircraft with multiple high-current draw servos (e.g. giant-scale aircraft, jets,
etc.), the Cockpit can provide constant current of up to 20 amps. Each battery
input is regulated independently to 5.9 or 7.4 volts and each regulator is capable
of handling 10 amps (2 x 10 A). This offers true dual battery redundancy and a
fail-on SensorSwitch for the ultimate in reliability. By locating four remote receivers
throughout the aircraft, the RF link can be optimized in even the most demanding
aircraft installations that have significant conductive materials like carbon, stainless
steel bypass tubes, tuned exhausts, etc.

The Spektrum Cockpit main unit is not a receiver. The Spektrum Cockpit’s main unit
is a power distribution center that provides up to 20 amps of current to power your
integrated gear and door sequencer and servo matching system. Through extensive
testing, our engineers discovered that mounting the unit in the typical location in
a sophisticated aircraft (an aircraft with many high-current draw servos and/or
conductive materials) at the end of the servo and battery leads is not the optimum
location to provide the clearest RF signal. The Spektrum Cockpit uses four remotely
mounted receivers that can be optimally placed in your aircraft to provide the best
possible RF link.

Battery Requirements

Using One Battery

The Spektrum Cockpit allows the option of using one or two battery packs.
When using one battery, simply connect the battery into either of the two battery
connectors (BATT 1 or BATT2).

Using Two Batteries

The Spektrum Cockpit offers a true redundant dual battery system with built­in dual voltage regulation. When using two battery packs, each pack functions
independently and is isolated from the other so that if one pack should fail (open
circuit, short circuit or become discharged), the other battery will provide power to
operate the system.

When using dual batteries, it’s important that both batteries be of the same capacity,
number of cells and ideally of the same age and condition. Keep in mind, however,
that it’s normal for one battery to discharge slightly more than the other. This is
the nature of an isolated battery system. The battery that has the higher voltage or
lower internal resistance will discharge at a faster rate. Generally, the difference is
negligible (less than 10%).

When using two batteries, the total available capacity equals the sum total of both
batteries, for example, BATT1 (2000mAh) + BATT2 (2000mAh) = a total capacity of
4000mAh.

Battery Capacity

It’s important to select a batteries that have more than adequate capacity to provide
the necessary flight time. Current draw varies depending on your servos, installation
and flying style.

40–45% aerobatic aircraft with 9–12 high-current servos: 4000–8000mAh
33–35% aerobatic aircraft with 7–10 high-current servos: 3000–6000mAh
25% quarter scale aerobatic aircraft with 5–7 high-current

servos:
Jets–BVM Super BANDIT, F86, Euro Sport, etc.: 3000–6000mAh
Giant-scale jets–BVM Ultra Bandit: 4000–8000mAh

Recommended Guidelines for Battery Capacity

Scale aircraft—The varieties of scale aircraft and the accessories they use vary

tremendously, making it difficult to give capacity recommendations for these types
of aircraft. Using the previously mentioned aerobatic guidelines, relative to the size
and number of servos used, will provide a conservative capacity for your scale
aircraft. As always, check the battery charge condition before each flight.

Battery Voltage

CAUTION: D0 NOT use a 4-cell, 4.8-volt battery to power the Spektrum

Cockpit. Four-cell, 4.8-volt batteries do not provide enough voltage headroom
(additional margin needed) necessary to power the system when heavily loaded.
Under load, the system voltage can drop below the voltage system’s minimum
operating voltage threshold (3.5 volts) and cause loss of control.

The Spektrum Cockpit is capable of handling voltages from 6.0 to 9.0 volts. The
voltage limitations are generally the servos. The output voltage of the servos are
regulated to 5.9 or 7.4V. Each voltage regulator is capable of handling 10 amps for a
total of 20-amp continuous current capability.

CAUTION: NiMH batteries have a tendency to false peak when being fast

charged. Always make sure NiMH batteries are fully charged and have not
false peaked during charging.

6

2000–4000mAh

Many pilots use 2-cell LiPo batteries to power their aircraft. LiPo batteries offer
greater capacity for their size and weight and are easier to manage when charging.

CAUTION: When not in use, always disconnect the battery from the Spektrum

Cockpit to prevent over-discharge. Batteries discharged below recommended
voltage may become damaged, resulting in loss of performance and potential fire
when batteries are charged.

CAUTION: When charging any brand of NiMH battery pack, make sure the

battery is fully charged. Due to the nature of peak charges and variations in
charging rates, heat development and cell types, the capacity reading of a battery
charged on a fast peak charger may only reach 80% of its nominal value. Use a
charger that displays total charge capacity. Note the number of mAh put into a
discharged pack to verify the charge is at full capacity.

Installation

The Spektrum Cockpit requires a minimum of three remote receivers to be plugged
in for the system to operate. Each receiver functions independently and offers a
more secure RF link in difficult environments. The added security of redundancy,
should a failure occur, outweighs the additional weight and cost penalties.

Installing the Spektrum Cockpit Main Unit and SensorSwitch

1. Using the 4 included screws, drill 4, 1/16” pilot holes into a plywood or hardwood

mount. Secure the main Cockpit unit in the position desired.

2. Mount the switch on the side of your aircraft and insert the switch plug in the
SensorSwitch port in the Cockpit unit. Make sure to install the connector with the
ribbon cable facing up. In models with severe vibration, secure the ribbon lead by
at least one additional point to prevent the connector from coming loose. If the
connector falls out in flight, you will need to connect the SensorSwitch again to
power off the Cockpit.

NOTICE: The Spektrum Cockpit uses a specifically designed switch. Conventionally
wired switches are not compatible with the Spektrum Cockpit.

3. To power on the Spektrum Cockpit with the SensorSwitch, press and hold the SET
button on the SensorSwitch until the central LED glows red. Press buttons I and II
separately to turn each battery on. If you have only 1 battery installed, you only need
to press the button for that battery.

4. To power off the Spektrum Cockpit with the SensorSwitch, repeat the procedure
for turning the unit on in reverse order. Intermittent contacts or interruptions in the
battery power cannot power off the Spektrum Cockpit.

Installing the Batteries

Using the guidelines mentioned earlier, select the battery system that best fits your
application and install the battery(s)/regulator(s) in your aircraft. Connect the battery
to the Spektrum Cockpit. Spektrum PowerSafe™ batteries are pre-wired with an
EC3 connector and require an EC3 to MPX adapter to connect to the Spektrum
Cockpit. It is essential to maintain the correct polarity as connecting a battery with
reversed polarity will instantly damage the Spektrum Cockpit’s internal regulators
and will prevent the Spektrum Cockpit from working. The default battery type setting
is for Lithium Polymer (LiPo) 2-cell packs. If you wish to use other battery types, the
specific battery type must be set using the Power Manager feature described later.

Patented MultiLink™ Receiver Technology

The AR12200 supports four receivers, offering the security of multiple path RF
redundancy. External receivers attach to the main unit using extensions. Installing
these receivers in different places in the aircraft exposes each receiver to its own RF
environment, greatly improving path diversity (the ability for the receiver to see the
signal in all conditions).

Antenna Polarization

For optimum RF link performance, mount the remote antennas in an orientation
that allows for the best possible signal reception when the aircraft is at all
possible attitudes and positions. This is known as antenna polarization. Mount one
antenna vertically, one horizontally in-line with the fuselage and one horizontally
perpendicular to the fuselage. Installing antennas in this pattern offers optimum
cross-section visibility.

Receiver Installation

While Spektrum 2.4 GHz systems are far more resistant to interference caused
from internal RF generating sources, the remote receivers should be mounted as far

away as practical (typically 4” or greater, if possible) from the following:

• Ignition systems

• Ignition batteries

• Ignition switches

• Engines

• ECUS pumps

• Electric motors

• Receiver batteries

• Fuel tanks

• Metal bypass tubes

• High-temperature components like exhaust systems

• Any signicant metallic conductive components

• High-vibration areas

Mount the remote receivers a minimum of at least 2” apart from each other as

greater antenna separation gives improved path diversity (RF link performance)
in critical environments. In large aircraft where space is not an issue, mount the
antennas throughout the aircraft as illustrated below. Spektrum offers remote

receiver extensions ranging from 6” to 36” to ensure the receivers can be mounted

in the most optimum locations throughout the aircraft.
Using double-sided foam tape and tie wraps, mount a minimum of 3 remote

receivers in your aircraft and connect the receivers to the receiver ports of the
Spektrum Cockpit. The following illustrations show typically recommended
installations. Note the remote receiver orientation.

Mounting the Remote Receivers

• 35% aerobatic plane with single NiMH battery and three remote receivers

• 35% aerobatic plane with dual NiMH batteries and three remote receivers

• 40% aerobatic plane with dual LiPo batteries and four remote receivers

EN

• Jet with dual LiPo batteries and four remote receivers

Installing Servos

Connect the servo leads to the appropriate ports in the Spektrum Cockpit and
prepare to bind the system to your transmitter.

The Spektrum Cockpit has 4 dual-matched channels available to operate 2 separate
ailerons, rudders, aux 1, flap or any other available channel servos. Use the built-in
servo matching feature to adjust each of the 4 dual-channel servo ports to match
each other. These ports can be matched at the servo center points as well as each
endpoint.

NOTICE: Failure to match ganged servos throughout the range of motion on a
control surface will result in high amperage drawn by the servos, which can lead
to servo failure. Use an inline current meter (such as the HAN172) to adjust for
decreased current draw in the system.

NOTICE: Only use standard, non-amplified Y-harnesses and servo extensions with
Spektrum equipment. Use of amplified Y-harnesses or servo extensions will cause
the servos to operate erratically or not function with Spektrum equipment. Amplified
Y-harnesses were developed to boost the signal for some older PCM systems and
should not be used with Spektrum equipment. When converting existing models
to use Spektrum equipment, make sure all amplified Y-harnesses and/or servo
extensions are replaced with conventional, non-amplified versions.

The JR® PCM Y-Harness with Amplifier (JRPA133) is not compatible with the
AR12200 and should not be used.

Binding

Always connect three or more remote receivers to the Spektrum Cockpit for correct
linking and binding to a transmitter. Connecting fewer than three remote receivers
will cause the Cockpit to operate incorrectly.

Bind the Cockpit to your transmitter, so:

The Cockpit recognizes your transmitter, ignoring signals from other sources
Transmitter control and servo failsafe positions are set and saved in the Cockpit

during binding.

After charging the batteries

Reset the Cockpit so reliable values for energy consumption and operating times are
displayed.

To reset the Cockpit battery:

With the system powered on, press and hold buttons I and II on the SensorSwitch
together until the following screen appears:

After this screen appears, release buttons I and II and the capacity available is reset
to the value you have stored for the battery capacity.

When the Cockpit is powered on, the following main screen will appear with the
following information:

Graphic voltage indicator

The graphic voltage indicator provides the batteries’ state of charges. This
display is only correct for the current type of battery selected. If the connected
battery is fully charged, the charge bar will extend to the top of the voltage indicator
box. If the bar only fills the bottom third of the box, the corresponding battery is
almost discharged. This indicator is supplemented by the residual capacity display.

Graphic display of the minimum voltage value

This displays the minimum voltage for the battery type selected. If the voltage is
below this mark, the batteries must be charged.

Operating Time

This displays the elapsed time since the last RESET of the battery capacity as
described above. It is important to perform a RESET each time the batteries are
charged.

Graphic Indicator of the battery charge state

This displays the battery charge remaining. Assuming the battery is of good
quality, if the bar reaches the halfway point, then the battery is halfway depleted.

Digital voltage display

This displays the voltage of the battery in a numerical format.

Output voltage

This displays the Cockpit’s output voltage to the servos.

Residual battery capacity

Assuming that you have previously set the battery type correctly and have
performed a RESET of the capacity of the battery after charging , this displays the
momentary capacity value of the battery. Keep in mind, however, that aging effects
and defective batteries may falsify this value. Residual capacities shown on the
screen may appear different during battery discharge. This may be due to small and
unavoidable differences in discharge rates between voltage regulators matched at
the factory. In practice, if the remaining capacity appears to be high but the voltage
is low, immediately check the battery for problems.

Sequencer

The Cockpit unit supports door sequencer (DS) programming. Doors can be set to
open and close and gear to extend and retract as needed. Look at the unit to see the
six ports marked DS, 1 through 6, available for sequencing and timing. Plan how you
want to sequence and time what you connect using the information below. .

• Servo Position I: (Starting servo position, 700 micro seconds to 2300 micro

seconds)

• Servo Position II: (Ending servo position, 700 micro seconds to 2300 micro

seconds)

• Start Time (This can be set to a delay for the movement to occur, 0–9.9sec)

• Stop Time (This is used to slow the movement from the start position to the end

position 0–9.9sec)

Example

Values for the retraction/extension positions will vary according to linkages and
must be set up individually to suit your model. Ensure that the wheel and door
positions do not mechanically stall or block the servos and that the timing suits the
requirements of your model.

Sequence for retracting the gear

Task 1 is used to open the main wheel door when the transmitter switch is moved
from position A to position B. The selected stop time (three seconds) causes the
door to open slowly.

Task 2 controls the secondary wheel door. The servo for this function is installed in
the reverse orientation, as can be seen from the position values.

Task 3 is responsible for operating the nose wheel door. After a period of 3.5
seconds (set in Task 4), the gear is extended, and, after a brief pause, the wheel
door closes again.

Task 4 controls an electronic pneumatic valve for the retractable undercarriage.
The valve will open after a delay of half a second once the wheel doors have
reached their position; at this moment, it feeds compressed air into the air cylinders.
The switching points are programmed on the valve itself after the door sequencer
has been programmed.

Task 5 closes the wheel door that opened in Task 1 1.5 seconds after the gear is
extended. In this example, it closes even more slowly than when opened.

Task 6 closes the secondary wheel door of the main gear.

12

Sequence for extending the gear

Task 1 opens the wheel door at the same times that were selected for retracting
the gear. The only change that needs to be made is the direction B->A must be
selected at the Action point. The software automatically copies the values for
positions I and II as soon as you select Servo 1.

Task 2 opens the main gear door immediately when the retract switch is moved
from position B to A.

Task 3 immediately starts to open the nose wheel door when the transmitter switch
is operated, but slowly.

Task 4 operates the electronic valve again and the gear is extended.
Task 5 closes the main wheel doors slowly.
Task 6 closes the secondary main wheel door after the gear is extended with a

delay of 1.5 seconds.

EN

This example shows how a complex function is put together. It is also possible to
insert additional movements or intermediate stops at any time when opening or
closing the doors by using tasks 7 to 12.

Servo Matching

The Cockpit unit supports servo matching (ganging) in a menu item, when using
four pairs of ports marked A through D. For example, two servos attached to a single
aileron can be connected to port A, decreasing current draw and fighting between
these two servos.

Start by initializing the match channels you
will use by setting the Initial Servo Center
Position described later in these instructions.
Set up the maximum travel and expo functions
completely before matching the servos.

To match servos using the Servo Matching
function, perform the following steps:

1. Disconnect the control surface linkages from the servos to avoid high forces

acting upon the currently unmatched servos.

13

EN

2. Select the output port to adjust, A–D. The channel for the output ports of the

Cockpit are determined in the Servo Mapping function.

3. Select the Servo to adjust, 1–2. Either of the 2 channels can be adjusted,

allowing greater flexibility in servo matching.

4. Move the stick, switch or other controlling device of the transmitter to the desired

position and hold. Note that when the output channel is moved, the arrow will
move on the screen, indicating which parameter is ready to adjust.

5. Select Start with the SET button on the SensorSwitch.

6. Once Start has been selected, you can release the transmitter stick. The position

will be held until the SET button on the SensorSwitch is pressed again. Also
check that the disconnected ball link lines up correctly with the linkage point.

7. Press the SET button on the SensorSwitch to conclude the set-up process. Do

not re-connect the linkage until you have adjusted the center position and both
end points correctly.

8. To make further adjustments, move the transmitter stick in the desired position

and press SET again with the cursor at Start, then repeat the set up process.

9. If you wish to reverse the direction of rotation of a servo, move the control

surface to one end point and select the menu point Start with the SET button
on the SensorSwitch. Now press and hold button I or II until the control surface
moves in the opposite direction. Repeat the procedure for the other endpoint of
travel.

10. Typically, full throw on a servo will be within a range of 900 to 2100 micro

seconds with the servo’s center position at 1500 micro seconds.

CAUTION: Do NOT go beyond the servo’s maximum travel or damage to the

servo could result. Maximum throw varies from servo to servo.

11. Once the servos are matched, use a current meter to minimize the current

draw of each servo to prevent any fighting of the servos. Adjust the servos as
necessary with the linkages and the servo matching function to achieve the
lowest current draw possible at the center and endpoints.

RX/TX Settings

Several functions are in the RX/TX Settings menu, including: selecting DSM2 or
DSMX operation, binding the Cockpit, teaching fail safe positions, selecting the
frame rate, channel output mapping for the output ports and setting the transmitter
center stick positions.

TX System

In the TX System sub menu, DSM2 or DSMX operation can be selected as well as
the option for binding the Cockpit to the transmitter.

To select DSM2 or DSMX operation, press the I or II buttons on the SensorSwitch to
select the desired type, then press the SET button to confirm your selection.

Binding—This function is used to bind the
Cockpit to your transmitter. It is necessary to
bind the Cockpit so that it will only recognize a
specific transmitter, ignoring signals from any
other sources. If the Cockpit is not bound to a
transmitter, the system will not operate.
To bind the Cockpit to your transmitter, follow
these steps:

1. Attach all remote receivers to the ports labeled RX1 through RX4.

2. Select the Binding Menu option with the I or II buttons on the SensorSwitch and

press the SET button to place the receiver into Bind mode.

3. Follow your transmitter’s instructions to enter bind mode on the transmitter.

14

4. The system will connect within a few seconds. Verify that all remote receivers’

LEDs are glowing solid, indicating the system has been bound and is ready to
use.

Teach Failsafe

In the Teach Failsafe sub menu, the failsafe
positions are stored. In the event of a signal loss,
all servos will be driven to the position set.

Preset Failsafe allows you to set the specific
control positions for all channels to return to
should a signal loss in flight occur or at any other
time a successful connection has been made.

The Preset Failsafe is typically used to prevent “y aways” in high-performance

models by deploying spoilers in sailplanes or putting gas- and glow-powered
models into a slight turn at reduced throttle.

To program the failsafe channel positions, follow these steps:

1. Move all transmitter sticks, switches and pots to the desired failsafe positions,

typically to low throttle and centered controls. Set the positions as desired for
your model.

2. Press the SET button with the cursor next to Teach Failsafe.

3. All positions will automatically be stored and ready to use.

Frame Rate

Frame rate indicates the time interval at which
the servo signal is refreshed. Many analog
servos are not compatible with higher frame
rates. For many analog servos, it will be
necessary to select the 21ms setting.

NOTICE: Set this rate to your servo’s operating
rate or damage to your servos can result. For operating rates, refer to your servo
manufacturer’s documentation.

A faster refresh rate causes the servos to respond faster and will offer greater
effective torque because they are better able to counteract the forces acting on
them. The frame rate setting should only be changed if you know that your servos
are suitable for the frame rate you wish to use.

The frame rate adjustment is only available for the four dual-matched channels and
the sequencer output channels. All other channels operate at the same frame rate
as the cockpit.

To select the Frame Rate, complete the following steps:

1. After entering the Frame Rate function with the SET button on the SensorSwitch,

Output Mapping

The Output Mapping function allows the
output ports of the Cockpit to be assigned to
any of the 12 channels available. This allows
for customization of the advanced features
of the Cockpit. For instance, any of the 4 dual
ports can be assigned to any channel for servo
matching and the 6 sequencer channels can
be assigned to any channel desired.

To select the Output Mapping channels, complete the following steps:

1. After entering the Output Mapping function, move up and down through the

mapping function by pressing the I or II buttons on the SensorSwitch.

2. The A through L letters in the Output Mapping function correspond to the output

ports of the Cockpit. The channels in the Output Mapping correspond to the
channels of the transmitter.

3. To change an output port selection, press the SET button on the SensorSwitch to

select the output port desired.

4. Press the I or II buttons on the SensorSwitch to select the channel desired.

5. Press the SET button on the SensorSwitch to confirm the channel selected.

INIT Center Pos

The Initialize Center Position function is used to
set the center positions of each channel of the
transmitter. This is used for servo matching as
well as sequencing.

Complete the INIT Center Pos function before
setting up the servo matching and sequencer
for best results.

To select the Output Mapping channels, complete the following steps:

1. Move all transmitter sticks, pots, sliders and switches (where possible) to the

center positions.

2. With the cursor next to INIT Center Pos, press the SET button on the

SensorSwitch.

3. The center position of each channel is automatically set.

Power Manager

The Power Manager function is used to select
the chemistry type of the battery used, the
capacity of the battery pack, and the output
voltage to the servos.

Set the battery chemistry type, capacity of the
battery and the output voltage before setting the
rest of the functions on the Cockpit.

CAUTION: Ensure you select the correct battery type that you are using. Do not
use the NiMH battery setting while using a LiPo battery or the LiPo battery setting
while using a NIMH battery.

The default battery chemistry type is LiPo/Li-Ion. If this is the battery chemistry that
will be used, this step can be skipped.

16

Three chemistry types are available:

1. 2-Cell LiPo or Li-Ion

2. 5-Cell NiMh or NiCd

3. 2-Cell LiFe
The Output Voltage function is used to select the output voltage to the servos, either

5.9V or 7.4V. For most servos, this selection should be set to 5.9V. For HV or High
Voltage servos that can accept 2-Cell LiPo voltage, this can be set to 7.4V to take
advantage of the servos’ capabilities. Note, however, that in order to use the 7.4V
setting, all servos connected must be capable of handling this voltage.

CAUTION: 7.4V must only be selected on servos that are compatible with this
voltage, if 7.4V is selected on non-HV type servos, failure of the servos can occur,
resulting in a loss in control of the model.

Reset

The Reset function is used to reset the parameters of the Cockpit to the default
settings. The Sequencer, Servo Matching, and Output Map functions can be reset
individually without affecting other functions.

To Reset the Sequencer, Servo Matching or Output Mapping, perform the following
steps:

1. Select the desired reset option by using the SET button.

2. A pop-up message stating “Caution Reset Sure? No or Yes” will be displayed.

3. Press the I or II to select No or Yes as desired.

4. Press the SET button on the SensorSwitch to confirm the selection.
NOTICE: Once you have confirmed your choice by answering Yes, the values are
reset and the previous settings are lost permanently.

Standard Range Testing

Before each flying session, and especially with a new model, it’s important to
perform a range check. All Spektrum aircraft transmitters incorporate a range
testing system that reduces the output power, allowing a range check.

Range Testing

1. With the model resting on the ground, stand 30 paces (approx. 90 feet/28 meters)

away from the model.

2. Face the model with the transmitter in your normal flying position and put your

transmitter into range test mode. This causes reduced power output from the
transmitter.

3. You should have total control of the model in range test mode at 30 paces (90

feet/28 meters).

4. If control issues exist, call Horizon Product Support for further assistance.

Advanced Range Testing Using Flight Log Data

The Standard Range Testing procedure is
recommended for most sport aircraft. For
sophisticated aircraft that contain significant
amounts of conductive materials (e.g. turbine
powered jets, some types of scale aircraft,
aircraft with carbon fuselages, etc.), the
following advanced range check will confirm
that all remote receivers are operating optimally and that the installation (position
of the receivers) is optimized for the specific aircraft. This Advanced Range Check
allows the RF performance of each remote receiver to be evaluated and to optimize
the locations of each individual remote receiver.

Advanced Range Testing

1. To view the flight log data on the screen, press and release the I and II buttons

together while at the main screen and the flight log data will appear.

2. Have a helper hold your aircraft while observing the Flight Log data.

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

your normal flying position and put your transmitter into range test mode. This
causes reduced power output from the transmitter.

4. Have your helper position the model in various orientations (nose up, nose down,

nose toward the transmitter, nose away from the transmitter, etc.) while your
helper watches the Flight Log, noting any correlation between the aircraft’s
orientation and frame losses. Do this for 1 minute. The timer on the transmitter
can be used here. For giant-scale aircraft, it’s recommended that the airplane be
tipped up on its nose and rotated 360 degrees for one minute while recording
the data. Next, place the airplane on its wheels and do a second test, rotating the
aircraft in all directions for one minute.

5. After one minute, a successful range check will have less than ten recorded

frame losses. Scrolling the Flight Log through the antenna fades (RX1, RX2, RX3,
and RX4) allows you to evaluate the performance of each receiver. Antenna fades
should be relatively uniform. If a specific antenna is experiencing a high degree of
fades, then that antenna should be moved to a different location.

6. A successful advanced test will yield the following:

H: 0 holds
F: less than 10 frame losses

RX1, RX2, RX3, RX4: Frame losses will typically be less than 100. It’s
important to compare the relative frame losses. If a particular receiver has a
significantly higher frame loss value (2 to 3X) then the test should be redone. If
the same results occur, move the offending receiver to a different location.
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 flight. If any single antenna experiences over 500 fades in a single flight, 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 flight should be less than 20.
The antenna fades that caused the frame loss are recorded and will be added to
the total antenna fades.
A Hold occurs when 45 consecutive frame losses occur. This takes about one
second. If a hold occurs during a flight, it’s important to re-evaluate the system,
moving the antennas to different locations and/or checking to be sure the
transmitter and receivers are all working correctly. The frame losses that led to

the hold are not added to the total frame losses.
NOTICE: The Flight Log data is reset to 0 when you exit this screen display. It is not
possible to read out previous data again.

QuickConnect™ With Brownout Detection
(Brownout Detection not available with DSMX)

The Cockpit features QuickConnect with Brownout Detection (Brownout Detection
not available with DSMX). Should a power interruption occur (brownout), the
system reconnects immediately when power is restored and the LEDs on each
receiver flash, indicating a brownout (power interruption) has occurred (DSM2
only). 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 voltage to the Cockpit drops
below 3.2 volts, interrupting control as the servos and this unit require a minimum
of 3.2 volts to operate.

How QuickConnect Works

When the voltage drops below 3.2 volts, the system drops out (ceases to operate).
When power is restored, the Cockpit immediately attempts to reconnect. If the

transmitter was left powered on, the system reconnects, typically in about 4ms. The
receivers then blink, indicating a brownout has occurred (DSM2 Only). If at any time
the receiver is powered off then back on and the transmitter is not powered off, the
receivers will blink as a power interruption was induced by powering off the Cockpit
(DSM2 Only).

CAUTON: If a brownout occurs in-flight, it is vital that you determine the
cause of the brownout and correct it. QuickConnect and Brownout Detection allow
you to safely fly through most short duration power interruptions, however, the root
cause of these interruptions must be corrected before the next flight to prevent
catastrophic safety issues.

Tips for Getting the Most from your Cockpit System

Flight Log

The Flight Log can be used to test the battery system using the built-in voltmeter
and applying a load to the servos/control surfaces. The voltage should never drop
below the rated voltage (5.9 volts) even under a heavy load.

When the system is first installed, an advanced range check should be performed.
If any receiver is performing less than optimal (higher than normal fades), that
receiver should be repositioned and the advanced range test repeated until low
fades are recorded.

During first flights with sophisticated airplanes (significant conductive materials
onboard, many high-current draw servos, carbon construction, etc.), it’s good
practice to keep your first flight in close, then confirm the RF link performance using
the Flight Log to determine the performance of each attached receiver. Extend the
distance on subsequent flights and record the Flight Log data, confirming that all
systems are performing properly.

Storing Your System

If the system will be stored for more than two weeks, it’s important that the battery
be disconnected from the Spektrum Cockpit.

CAUTION: When a battery is connected to the Spektrum Cockpit, a low current
drain of less than 1mA occurs even when powered off using the SensorSwitch.
If the system is going to be stored for any length of time, always disconnect the
battery from the Spektrum Cockpit to prevent over discharge and damage to the
LiPo battery.
