Multiplex COCKPITmm User Manual
Instructions
Dear customer,
Dear fellow -modeller,
The COCKPITMM: that’s the name of the new system from MULTIPLEX. We have used
this name before, on a transmitter which we introduced in 1985, but the new Cockpit is not comparable in any way with the earlier version. The new transmitter incorporates micro-processor technology, and it is this which provides its wideranging facilities and operating convenience. The new system features many inte resting and useful innovations which modellers could ha rdly have imagined at the
time of the earlier Cockpit:
The COCKPITMM’s primary features:
• 7 channels, PPM transmission
• 9 model memories with copy function
• Suitable for fixed-wing aircraft, helicopters and vehicles
• Simple programming based on a 3D digi-adjustor and 2-line
LCD screen with up to 11 symbols
• Digital trims with trim memory
• Programmable servo reverse, centre, and end-points (both directions) for all 7
channels (3-point curve)
• 9 mixers for fixed-wing model aircraft: combi-switch, aileron differential,
V-tail mixer, delta mixer, flaperon mixer, spoileron with aileron differential su ppression, 3 x elevator trim compensation for motor, control E (flap), and control
F (spoiler)
• 3 mixe rs for helicopters
• „MOTOR OFF“ switch as emergency motor stop
• Choice of 8 primary control configurations (stick modes)
• Switchable reduced travels (Dual Rates) for 3 channels
• Expo for 3 channels
• Stopwatch, operating hours timer
The name „Cockpit“ is also intended to reflect the aim which we kept in mind all the
time when developing this system:
„Just as in a ‘full-scale’ cockpit, the model pilot should be able
to reach and control all the essentials quickly and easily.“
And the „MM“? Quite simple: MM is two thousand in Roman numerals, and we use it
to show that the Cockpit is our contribution to the theme of the new millennium.
Please read right through these instructions carefully before you use your new RC
system for the first time. This will help you to get to know the COCKPIT MM’s features quickly, so that you can exploit its many facilities to the full.
We hope you have many hours of fun and pleasure with your new system.
Yours the MULTIPLEX team

2. Safety
Radio controlled models are not playthings!
Safety in RC modelling is of extreme importance, and you can make the greatest
contribution to it yourself, simply by handling and using your radio control system
and model carefully, responsibly and conscientiously.
• Check all electrical and mechanical connections in the model regularly.
• Check regularly that all control surfaces work smoothly, freely, and without slop
(disconnect the linkages to check this).
• Carry out regular range checks (see 12.2. Range testing).
• Check with other pilots and the site flight line director that your channel is not
already in use. The Channel-Check module (optional accessory - see 10. Channel-Check) provides an extra level of security.
• Before launching your model extend the transmitter aerial to its full length and
check that it is in good condition and firmly secured.
• Check that the transmitter is set to the correct model memory.
• Before every flight check all the working systems as follows:
Do all the control surfaces work in the correct „sense“ relative to the stick
movements? Are the control surface travels correct? Have you set the appropriate mixers for the model, and have you adjusted them corre ctly?
• Are the transmitter and receiver battery adequately charged, and in good, wellmaintained condition?
• Use only genuine MULTIPLEX crystals, batteries and accessories.
• Read and observe the recommendations for any components of your receiving
system whic h are not covered by these operating instructions.
If you are not sure of any of these points, do not launch the model! Check everything again in peace and quiet, and give yourself a chance to locate and remedy the
fault. If you still cannot eliminate the problem, ask your model shop or the
MULTIPLEX customer service department for advice and assistance.
! Read Chapter 12. - The system in use -
and keep to the recommendations !

4. Switching on for the first time
4.1. Preparation
4.1.1. Charging the transmitter battery
On the left-hand side of the transmitter you will find the MULTIPLEX universal
socket. We call it „universal“ because you can use it for several functions:
• charging the transmitter battery,
• connecting the cable for teacher/pupil operation (9.2. Teacher/pupil mode), and
• connecting the cable for diagnosis operation (12.3. Using the diagnosis lead).
Charging the battery - important note:
•• Automatic battery fuse
The battery installed in your transmitter is fitted with an internal the rmal fuse.
The COCKPITMM must be used only with a genuine MULTIPLEX battery
fitted with this type of fuse.
This fuse protects the battery from excessive current flow if a short-circuit should
occur.
When the short-circuit is removed, the fuse element cools down within about
!!
one minute, and the battery then works again normally.
•• First connect the charge lead to the charger
Always connect the charge lead to the battery charger first, and only then to the
transmitter. If you do it the other way round, the banana plugs on the charge lead
could touch and short-circuit the battery.
•• When charging the battery please note:
Normal (slow) charging:
Rapid charging with automatic charge termination: do not exceed the maximum
current stated in the operating instructions. If you ignore this, the fuse element may
trip, and the charge process will be broken off prematurely.
Never exceed the charge currents stated by the manufacturer!
no restrictions or special measures required.
4.1.2. Charging the receiver battery
The same recommendations apply to the receiver battery.
Read the manufacturer’s charging notes, which are printed on the
battery. The charge currents stated by the manufacturer must not be
exceeded!

4.1.4. Fitting the transmitter crystal
First open the transmitter (Fig. I). Transmitter crystals are fitted with a blue plastic
sleeve and bear the code letter „S“ before the channel number. Check also that the
crystal is correct for your transmitter’s frequency band.
You can tell the frequency band of any MULTIPLEX transmitter by the colour of the
aerial wire (flexible wire from the main circuit board to the aerial):
• orange = 35 MHz band
• green = 40 MHz band
• red = 72 MHz band
Fit the transmitter crystal in the appropriate socket on the main circuit board
(see Fig. II).
Please be very careful when handling crystals:
• Don’t let them fall
• Don’t force them into the socket
• Don’t subject them to vibration in use or in storage
4.1.5. The transmitter sticks
The sticks of the COCKPITMM transmitter feature:
• variable spring tension
• selectable self-neutralising action or ratchet (non-neutralising)
• height-adjustable stick tops
Adjusting the stick tension (see Fig. III)
The sticks of your transmitter are fitted as standard with neutralising springs. This
means that the sticks always return to centre when you release them. You can adjust the spring tension to suit your personal preference by rotating the M2 x 16
cross-point screws. Turn the corresponding screw clockwise to increase spring tension, and anti-clockwise to reduce spring tension.
Activating the stick ratchet (Fig. IV)
As standard the transmitter is supplied with all four primary stick functions selfneutralising. However, for many functions (e.g. throttle or spoilers) the neutralising
action is not required. For this reason any of the sticks can be converted from
„spring-neutralising“ to „ratchet“ operation if required. The parts required for the
conversion are supplied in a separate plastic bag in the transmitter packaging.
This is the procedure for activating the ratchet:
1. Disable the neutralising spring
Locate the M2 x 16 cross -point screw in the accessory bag and screw it fully into
the plinth designed for it.
2. Now screw the ratchet spring to the stick unit frame using the cross-point 2.2 x
6 mm screw.
Caution: don’t over-tighten the screw, otherwise you could strip the threads in
the plastic.
9
Replacing and adjusting the stick tops
The stick tops are a push-fit on the sticks; they are secured by a twisting motion.
1. To release a stick top rotate the plastic moulding until you feel it come loose.
The stick top can then easily be pulled off the stick shaft.
2. To fit a stick top, first fit the plastic moulding onto the stick and rotate it until it
slips easily down the shaft. Set it at your preferred length, and lock it by twisting the stick top through about 180°.
4.1.6. COCKPITMM expansion facilities and re-adjustment
In its standard form the COCKPITMM features up to 7 control channels (4 stick channels,
3 auxiliary channels), depending on the version you have purchased. You can convert or expand the transmitter to meet your individual needs and wishes.
Auxiliary channels
The three auxiliary channels (controls E, F, G) can be operated by any combination
of:
• slider (# 7 5720)
• rotary adjustor (# 7 5719)
• 2-position or 3-position switch (# 7 5742 resp. # 7 5740)
These controls are connected to the sockets marked E, F and G on the main circuit
board (Fig. V).
Important:
After installation or modification of controls re-adjustment is necessary!
If auxiliary controls are added or their connecting location is changed, all controls must be realigned. Do not attempt to realign the transmitter until you are
familiar with the operating philosophy of the transmitter (see 5. Operating philosophy).
This is how you realign controls:
Procedure
In the menu SETUP select –ADJ– and move to

• 2-pos. switch (# 7 5742) for auto-rotation select
• 3-pos. switch (# 7 5740 or # 7 5707 E/A/T)
for the timer and MOTOR OFF
• optional rotary adjustor (# 7 5719) for setting gyro gain (sensitivity)
General information for the supplementary installation of controls and switches
The slider can only be installed between the two primary stick units (see instructions supplied with slider). All the other optional controls can be installed in any
arrangement on the front face of the transmitter. As standard the mounting holes
are sealed with plastic blanking plugs.
For more detailed information on the way these auxiliary controls can be used
please read the appropriate section of these operating instructions.
4.2. What is supposed to happen?
We bet you are keen to try out your new radio control system immediately, and the
best way of doing this is to assemble a „test“ receiving system. We assume that you
have already carried out the Preparation as described in Chapter 4.1, and set stick
mode 1 (see 8.2.2., Selecting the stick mode).
If you have purchased the COCKPITMM with a MULTIPLEX The Brick/EinStein,
first plug the receiver crystal into the socket; the
crystal must be on the same channel as the transmitter. MULTIPLEX receiver crystals are fitted with Receiver crystal sleeve and are printed with the code
letter „E“ in front of the channel number. As already
mentioned, it is important to ensure that the receiver
crystal is correct for the frequency band on which the receiver operates.
As with the transmitter, you can tell the frequency band of any MULTIPLEX receiver
by the colour of the aerial:
orange = 35 MHz band
green = 40 MHz band
red = 72 MHz band
The transmitter and receiver must be on the same frequency band!
11
Receiver crystal
Now connect the charged receiver battery to The Brick/EinStein (or a conventional
receiver - see next page). The transmitter aerial is stored in the bottom of the case;
remove it and screw it into the socket on the front of the transmitter. You are now
ready to switch on the transmitter and The Brick/EinStein.
Always keep to this sequence when switching on and off !
>> First switch on the transmitter, then the receiver
(or The Brick/EinStein)
>> First switch off the receiver, then the transmitter !
What should you see on the transmitter?
• During power ON a short trill (quaver) is audible.
• The LED (red) is on for approx. 3 sec. and flashes afterwards every 3 sec.
• The screen will display the type and number of the
active model memory and the voltage of the transmitter battery. In the example on the right model memory
1 is active, and it is set to the Universal (UNI) type. The
battery voltage is 7.8 V in the sample display.
What is supposed to happen
at the receiver?
stick movement
Assuming that the transmitter is set
to stick mode 1, moving the left-
hand stick to the right, or pulling it
back towards you, should cause the
servos in the EinStein to move in the
RUDDER stick:
right
ELEVATOR stick:
back
up-elevator = climb
directions shown in the drawing.
Note that this might not apply if you
have already re-programmed the
transmitter.
If you have purchased a conventional receiving system instead of
The Brick/EinStein,
you must first connect a charged
receiver battery to the receiver via a
switch harness, then fit a receiver
crystal and connect two servos to the
receiver outputs 2 and 3.
Assuming that the transmitter is still
set to stick mode 1, moving the lefthand stick to the right, or pulling it
back towards you, should again
cause the servos to rotate in the directions as shown in the drawing.

5. The operating philosophy
5.1. Introduction
In the development of the COCKPITMM we gave priority to useful, practical adjustment
facilities and mixer functions in conjunction with a simple, easily understood
method of programming which could be implemented quickly. The two elements
which form the basis of programming the COCKPITMM are the 3D digital adjustor and
the LCD screen, which clearly and unambiguously shows the settings you have
selected.
All programming is based on ready-made menus. This is the simplest method of
programming, and is quick and easy to learn. Just select the menu you wish to use,
and then activate and adjust the settings. To do this all you need to use is the 3D
digi-adjustor: rotate it to leaf through menus, view settings and select values; press
it to change levels and switch from line 1 to 2 and back again.
The COCKPITMM offers a wide range of settings, and as this could be confusing they
have been assigned to two separate model types:
• UNIversal model type (U)
• HELIcopter model type (H)
The first step is always to define the type of model you wish to control, i.e. to select
the appropriate model type, as this makes available the settings appropriate to that
model, and suppresses irrelevant functions. This guarantees a high level of clarity in
the programming procedure. The settings are assigned to six different menus, again
with the purpose of keeping the process simple and easy to understand.
The table below represents a summary of these programming instructions in the
form of a flow chart covering the menu structure, together with a short-hand indication of how to operate the 3D digi-adjustor to move through the menus.
Keep this flow chart to
hand at all times when
you are programming
your COCKPITMM for the
first time. You will find it
a useful guide and reminder, and you will
soon find that you intuitively know how to
manipulate the 3D digiadjustor to get the
results you want.

5.2. Screen and 3D digi-adjustor
The LCD screen consists of two lines, each capable of displaying 6 letters, numbers
or symbols, and it forms the basic means of showing the menus and settings currently in use.
When you first switch on the transmitter you will see operating screen 1:
model type (e.g. UNI)
Trim display (4x)
Operating voltage (e.g. 7.8 V)
The first line always helps to orientate you, i.e. it tells you where you are currently
located within the menu structure of the program. Assuming that you are at the
parameter level (see flow chart), the bottom line is where the actual programming
is carried out: changing settings, activating mixers etc.
5.3. Example: selecting your language
Here is a brief example in tended to illustrate how the 3D digi-adjustor is used, and
what can be seen on the screen:
The Cockpit MM features a language select function, i.e. you can switch those texts
which are not internationally comprehensible from the default German to English.
In this example we will use this facility. Keep the flow chart to hand for this. As you
will see from the chart, you select your chosen language as follows:

the first line (orientation line) to the second line (setting line) by pressing the 3D
digi-adjustor once. Once the cursor is in the second line you can adjust the setting
by rotating the digi-adjustor. The cursor moves from the first to the second line to
confirm that you have moved to that part of the program.
