8.4 Switching the receiver ON and OFF
in normal operations
8.4.1 Sequence of switching ON and OFF
To switch the M-LINK RC system ON, please use this
procedure:
1. Switch the transmitter ON.
2. Switch the receiver ON.
The receiver LED flashes slowly and evenly
(LED code 3
8.1):
⇒ An M-LINK signal is being received,
the RC system is ready for use.
To switch the M-LINK RC system OFF, please use this
procedure:
1. Switch the receiver OFF.
2. Now switch the transmitter OFF.
8.4.2 Locating and correcting faults when switching ON
Fault:
The receiver LED lights up constantly when switched on (LED
code 1 8.1), but does not flash.
Cause:
No M-LINK signal detected.
Remedy:
•
Is the transmitter switched on?
•
Is the transmitter generating an M-LINK signal?
•
Are the transmitter and receiver bound to each other?
•
Have you carried out a receiver RESET (
•
Have you made changes to the setting for "Fast Response"
( 8.3) or "France mode" (
Error:
The receiver LED stays off after switching on
(LED code 0 8.1).
Cause:
The operating voltage (battery voltage) is too low.
Remedy:
•
Recharge the receiver battery or drive / flight battery.
8.5 HOLD and FAIL-SAFE
If no signal is picked up, or if the received data is corrupt, the
last valid information is passed on to the servos in order to
bridge the signal loss (HOLD mode).
If interference should occur and FAIL-SAFE has been invoked,
the servos (...) run to a previously defined position at the end of
the HOLD period (0.75 seconds). FAIL-SAFE mode ends as
soon as error-free signals are picked up again.
FAIL-SAFE is switched OFF in the receiver's default state (as
delivered), and after a RESET. FAIL-SAFE is activated using the
SET button on the receiver, or - in the case of certain trans-
mitters - "by radio".
If you wish to disable FAIL-SAFE again, the receiver must be
reset to the default state (RESET
must repeat the binding procedure (
! Note: always activate FAIL-SAFE!
For safety reasons we recommend that you always activate
FAIL-SAFE, and ensure that the selected FAIL-SAFE settings
will cause the model to take up as safe an attitude as possible
(e.g. motor idle / electric motor OFF, control surfaces neutral,
landing flaps deployed, tow-release open, ...).
Selecting the FAIL-SAFE settings:
Use your transmitter to move all the servos (and the speed
controller) to your preferred FAIL-SAFE positions. Press the SET
button briefly (0.5 to 1 second). The FAIL-SAFE positions are

Testing the FAIL-SAFE positions:
Move the sticks to positions other than the FAIL-SAFE settings,
and then switch the transmitter OFF: the servos should go into
HOLD mode briefly (0.75 seconds), and then move to the FAIL-
SAFE positions which you previously selected.
The FAIL-SAFE positions must always be checked and updated
when necessary, e.g. when you install the receiver in a new
model.
! Checking the FAIL-SAFE function:
For testing the FAIL-SAFE function only, the receiver can be
operated with the transmitter switched off. Caution: if the FAIL-
SAFE settings are incorrect, the motor could burst into life: injury
hazard!
After sixteen seconds in FAIL-SAFE the receiver ceases to send
control signals to the servos. Analogue servos and some digital
servos (see instructions) then become "soft", to avoid them
being stalled. Modern speed controllers switch themselves off.
However, some digital servos remain "hard" and maintain their
last position.
8.6 RESET to factory default settings
The receiver settings can be reset to the factory default settings.
If you do this, all the settings you have entered, such as binding
information, FAIL-SAFE settings are lost permanently.
Hold the SET button pressed in for at least ten seconds (as a
guide, the LED goes out when you press the button, comes on
again after two seconds, then off again after ten seconds).
When the RESET has been carried out, the LED displays the
confirmation signal (LED code 5
switches to binding mode.
! Note: it is not possible to carry out a RESET if the receiver is
in binding mode (LED flashing at high frequency).
9. RX D M
ATA ANAGER
All MULTIPLEX M-LINK receivers are based on modern micro-
controllers (FLASH technology). The RX-9-DR light M-LINK can
be connected to a PC or notebook running the PC program RX
DataManager using a PC connecting lead (# 8 5149).
The PC program RX DataManager is available as a free down-
load from the MULTIPLEX website (www.multiplex-rc.de). This
program can be used to carry out firmware updates, enabling
the user to maintain the receiver at the latest state of develop-
ment at all times.
10. I
NSTALLATION
• Protect your receiver from vibration, especially in models
powered by an internal-combustion engine (e.g. pack it loosely
in foam).
• Locate the receiver at least 150 mm away from electric mo-
tors, petrol engine ignition systems and any other electronic
components such as speed controllers for electric motors and
drive batteries. Do not route the aerials close to these compo-
nents.
• Install the receiver in the model in such a way that both
aerials are as far away as possible from electrically conduc-
tive materials, and are arranged at an included angle of 90°.
Locate the two aerial ends as far from each other as possible.
• If the model's fuselage contains conductive material (e.g.
carbon fibre), the aerials must be installed in such a way that
the active part of the aerial (approximately the last 30 mm) is
located outside the model.
