Diagnosis Mode - Multiplex RX-7 SYNTH IPD Instructions D'utilisation

15. R RESET
ECEIVER
The receiver settings can be switched back to the factory default values.
All settings (e.g. RF channel, FAIL-SAFE settings) are lost when you do
this, and are reset to the factory defaults.
Sequence
1. Switch the transmitter on, then switch the receiver on. The LED
flashes:
1,6 sec
LED Code 3
2. Press the button and hold it pressed in until the LED goes out - after
about 10 seconds.
The LED now flashes the confirmation signal:
1,6 sec
LED Code 5
The signal output is switched off after you carry out a RESET. The receiver
can only be used again after switching it off, then on again (
A RESET can also be triggered without a transmitter signal. For this to
work an RF channel must have been set previously.
16. E
RROR COUNT
The receiver features three internal error counters for the following
errors:
Low voltage
Reception blind spots (severe field strength fluctuations)
Signal interference
The LED displays the sum of the errors in the three error counters as soon
as an error is detected:
1,6 sec
LED Code 6
1,6 sec
LED Code 7
1,6 sec
LED Code 8
In our experience the errors described here occur during most flights.
Signal errors in particular occur quite often with FM/PPM transmission.
Generally speaking, the operator does not even notice them, but the
highly sensitive signal error counter still registers them. After a few
sessions, with subsequent analysis of the error count, you will find the
error counter helpful as an early method of detecting irregularities in
operating the model, in order to eliminate problems (e.g. in the power
supply circuit, interference caused by the power system, electrical
"noise" caused by metal-to-metal contact, etc.
15.1 Low voltage error count
The counter records the seconds during which the voltage falls below
4.4 V, either briefly or constantly.
15.2 Field strength fluctuations error count (reception blind spots)
The counter records the seconds in which the field strength collapses.
Instances of constant low field strength (transmitter off) are not counted.
15.3 Signal interference error count
The counter records the seconds in which the signal packet is not within
the prescribed format, e.g. too many, too short or too long servo signals.
If voltage falls (voltage collapse), reception blind spots and signal
interference are not counted. If a blind spot occurs, signal interference is
not counted. However, signal errors often occur before or after a collapse
in field strength or voltage, and these are counted.
Note:
If the voltage falls below 3.0 V for a long period, the receiver's processor
will restart. If this should happen, the values for all three error counters
are lost.
Note: power-on delay
The error counters only start operating after a delay of 20 seconds after
the receiver is switched on.
Note: error counter when the IPD filter is OFF
If the IPD filter is switched off, the receiver does not count the signal
errors, and no errors are displayed. Errors are only displayed again when
the IPD filter is re-activated (

IAGNOSIS MODE
Diagnosis mode can be helpful when you need to carry out adjustments
on the model, but the transmitter cannot be allowed to radiate an RF
signal. The transmitter (MULTIPLEX transmitter with multi-function
socket) is connected directly to the receiver using an MPX switch harness
with charge socket and a diagnosis lead, # 8 5105. The switch harness
must be connected to the socket marked "B/D" (D = Diagnosis)
When you switch the system on, the receiver detects that the diagnosis
lead is connected. The signal packet is received directly from the
transmitter via the diagnosis lead, and not via the RF link.
The RF signal is not restored automatically when you disconnect the
Diagnosis lead. The receiver must first be switched on again.
Note:
First switch the receiver OFF, then the transmitter OFF, then disconnect
the Diagnosis lead.
During Diagnosis operations the LED glows constantly. The error counter
10. ).
does not operate during Diagnosis operations.
18. RX-SYNTH S
If the receiver is permanently installed in the model, and the button and
LED on the receiver are not accessible, the unit can be controlled using
the RX-SYNTH set-up lead which is available as an optional accessory.
Connect the lead to the socket marked "B/D", and install it in an easily
accessible location on the model. The RX-SYNTH set-up lead can be
extended if necessary using a standard UNI extension lead
(e.g. # 8 5031).
The RX-SYNTH set-up lead features a 3-pin connector marked "PC". This
can be used to connect the receiver to a PC (
Note:
When you press the button on the RX-SYNTH set-up lead, the LED on the
set-up lead does not light up! The LED in the receiver continues to work
in the normal way if the button on the RX-SYNTH set-up lead is pressed.
19. RX-SYNTH D
All MULTIPLEX RX-SYNTH IPD receivers incorporate micro-controllers
(FLASH technology). This means that it is possible to connect the
receiver to a PC or notebook using the PC connecting lead
(# 8 5150).
You can download the RX-SYNTH DataManager PC program from
the MULTIPLEX website (www.multiplex-rc.de). This program opens
up more possible functions for the RX-SYNTH receiver:
Expanded receiver options, such as:
freely variable HOLD and FAIL-SAFE time, activate and adjust HOLD /
FAIL-SAFE channel by channel, set RF channel manually, ...
Software update
Scanner funktion
The channels in use on the corresponding frequency band are dis-
played in graphic form. With alarm and logbook function.
Read out error counter / memory
The error count for signal errors, field strength errors and operating
voltage can be read out separately.

AUTOMATIC SERVO CHANNEL COUNT DETECT
During the first four seconds after switching on (
detects the number of servo channels transmitted by the transmitter
(e.g. PPM 5, PPM 9) and stores this data. The number of servo channels
received from the transmitter is a criterion required by the IPD filter in
order to detect the transmission errors when the system is operating.
! Note: every time you change the number of servo channels or the
transmitter's operating mode (or when you use a different transmit-
ter), the receiver must be switched off, then on again.
You will also need to re-set the FAIL-SAFE settings (
The servo channel count or the transmitter operating mode are changed
on the MULTIPLEX ROYAL evo transmitter, for example, by altering the
servo assignment, e.g. PPM 6, 7, 8, 9 or 12.
