The RF channel search generally takes about 2 - 4 seconds. If
the process takes significantly longer, this indicates that no
clear transmitter signal is present. Check that your transmitter
is switched on, and that no other transmitter is in the imme-
diate vicinity. Repeat Step 1.
The LED glows continuously when a transmitter is located:

3. Now move one transmitter stick four times steadily to the
same end-point. The LED should go OFF in time with the
stick movement. This is your means of checking that the re-
ceiver has locked onto the correct RF channel.
The process is complete when the LED flashes the confirma-
tion signal:

4. The receiver must now be switched off, then on again (
10. 10. 10. 10. ); it will now be operating on the set RF channel.
The receiver stores the set RF channel permanently until either
you set a new RF channel, or RESET the receiver to the factory
default settings ( 15. 15. ). 15. 15.
Note: Note: Note: Note:
The signal output to the servo outputs remains switched off
during the RF channel search process, i.e. the servos do not
move and are "soft", and (modern) electronic speed controllers
stay OFF, because the signal is absent. Nevertheless, it makes
sense to secure the model and keep well clear of hazardous
parts.

When the RF channel is set, the receiver also detects the
transmitter's transmission format, i.e. how many servo channels
are transmitted (e.g. PPM 5, PPM 9), and stores this information.
The number of servo channels transmitted by the transmitter is a
criterion required by the IPD filter for detecting signal errors in
use.
Every time the receiver is switched on, it checks the servo
channel count and compares it to the stored value. If the two
are not the same, the receiver remains inactive.

Changes to the transmitter's servo channel count or operating
mode are made as follows: with the MULTIPLEX ROYAL evo by
changing the servo assignment (PPM 6, 7, 8, 9 or 12); with the
PROFI mc 3000 / 4000 series by changing the operating mode:
PPM 7, PPM 9, PPM12.

All MULTIPLEX RX-SYNTH IPD receivers can be operated with
positive Shift (e.g. MULTIPLEX, JR, AIRTRONICS) and negative Shift
(e.g. HiTEC, Futaba). By default the receivers are set to positive
Shift. If you wish to use a transmitter with negative Shift, you
must re-set the RF channel (

passed on directly to the servos, as with conventional FM/PPM
receivers, but are checked for interference and validity.
The advantages of IPD technology: The advantages of IPD technology: The advantages of IPD technology: The advantages of IPD technology:
1. Only permissible signals "get through"
IPD checks the signals for limit values: pulse widths within
the range 890 µsec and 2350 µsec are permissible. Most radio
control transmitters work within these limits, including other
makes of equipment.
2. "Invalid" signals are substituted (HOLD)
If an invalid signal is picked up, the receiver continues to
pass on the last received valid signal until a "good" signal is
received again (HOLD period). This suppresses interference, or
at least reduces its effects.
3. "Safety setting" in the case of total failure (FAIL-SAFE)
If no valid signal is picked up beyond the HOLD period (0.5
sec.) the IPD receiver moves the servos to a freely program-
mable setting (FAIL-SAFE position
control surfaces to neutral.
4. IPD monitors reception quality
The signal analysis process is automatically adjusted to suit
the current reception quality (field strength). Powerful signals
are passed on to the servos unchanged, but weak received
signals are "processed". The nominal servo positions are then
calculated from the last "good" signals. This greatly reduces
the effect of interference, but the pilot remains aware of the
problem (unlike with PCM). He receives a warning, and is able
to react appropriately.
5. IPD is compatible
IPD works on the same basis as the current FM-PPM trans-
mission pro-cess. IPD receivers, with all their advantages, can
therefore be used with most RC systems. A further advantage
of FM-PPM transmission lies in the fast signal transmission of
up to 12 servo channels, all of equal speed and value.
13. A
CTIVATING
The effect of the FAIL-SAFE settings is that the servos (etc.) take
up a pre-defined position, previously stored in the receiver, if
interference occurs.
If FAIL-SAFE has not been activated (factory default state, or after
a RESET (

remain in their last commanded position under no load (this may
equate to full-throttle!) until a valid signal is picked up again.

In the interests of safety we recommend that FAIL-SAFE should
always be activated, and the FAIL-SAFE settings should be
selected so as to bring the model to a non-critical flight situation
(e.g. motor idle / electric motor OFF, control surfaces neutral,
landing flaps extended, aero-tow release open, ...).
