ELEMETRY
The telemetry-capable RX-7/9/12-DR compact M-LINK 2.4 GHz
receivers offer a means of transmitting data from the model back
to the transmitter.
When these receivers are employed, the telemetric values for
"receiver battery voltage" and "connection quality" are transmitted
directly, i.e. they require no additional external sensors.
The receivers can also be used in conjunction with up to sixteen
external M-LINK sensors, which are connected to the "S" socket.
In this way a very wide variety of telemetry data can be "sent
back" to the pilot.
! Note:
The possible methods of indicating telemetry data by visual
and / or audible means vary according to the M-LINK trans-
mitter or RF module in use.
Examples of external M-LINK sensors are as follows:
Voltage sensor (# 8 5400).
Temperature sensor (# 8 5402).
Current sensor:
150 A (# 8 5405) or
35 A ((# 8 5403) or (8 5404)).
Rev count sensor:
Optical (# 8 5414) or magnetic (# 8 5415).
Vario / altitude sensor (# 8 5416).
GPS (# 8 5417).
For more information on connecting and operating the various
sensor types and their features (measurement range, addres-
sing, warning threshold settings, display facilities for minimum,
average or maximum values, in some cases activation of a
second measurement channel, ...) please refer to the instructions
supplied with the sensors and / or the MULTImate.

MATE AND
MULTIPLEX L
All MULTIPLEX M-LINK receivers are based on modern micro-
controllers (FLASH technology). In the case of most M-LINK
receiver types (see the operating instructions supplied with your
receiver) it is also possible to connect the unit to the MULTImate
(# 8 2094) and / or to a PC or notebook computer using the PC
connecting lead (# 8 5149); the PC program MULTIPLEX
Launcher can then be used.
The MULTIPLEX Launcher PC program is available as a free
download from the MULTIPLEX website (www.multiplex-rc.de).
This program, and the MULTImate (V1.50 or higher), opens up
the following facilities:
Availability of expanded receiver options, such as freely
variable HOLD and FAIL-SAFE period, individual FAIL-SAFE
settings can be activated and adjusted channel by channel,
...
Error counter / error memory read-out:
The error count can be read out separately for signal errors
and operating voltage errors.
Unrestricted sensor address assignment for the receiver
battery voltage and for connection quality (0 - 15).
Receiver name assignment (max. 12 characters).
Switching the following options on and off: "Two-receiver
mode" (
11.) and serial servo output (digital servo data /
SRXL-MULTIPLEX) (
Setting one sensor address as "priority address":
The selected sensor value is updated at a higher rate than all

Firmware updates:
Keep your receiver up-to-date at all times.
! Note:
We recommend that you update your MULTImate or the MULTI-
PLEX Launcher at regular intervals to ensure that you can
exploit all the current features of your receiver and the con-
nected components generally.

ECEIVER
MULTIPLEX RX-7/9/12-DR compact M-LINK receivers are what
are known as "dual receivers", ("DR"): each receiver case
contains two complete receiving circuits operating in parallel
("receiver diversity").
It is also possible to set up MULTIPLEX RX-7/9/12-DR compact
M-LINK 2.4 GHz receivers to operate in what is known as "two-
receiver mode":
In this mode two M-LINK receivers are inter-connected using a
Diversity lead (# 8 5070).
With this arrangement three or even four receive circuits operate
in parallel:
All three or four of the receive circuits built into the two receiver
cases pick up and assess the signals ("triple diversity" or
"quadruple diversity"). This form of diversity is also referred to as
"two-receiver mode".
The differing orientation of the (maximum) four receiver aerials
further improves the receive performance, since directional
aerial effects are minimised. This means that at least one
receiver aerial has a "good view" of the transmitter regardless of
the model's attitude. Two-receiver mode therefore provides a
wider safety margin. Two-receiver mode is particularly recom-
mended for use in large-scale models.
! Tip: you can also inter-connect different types of M-LINK
receiver, provided that they are capable of two-receiver mode
(e.g. 1 x RX-9-DR compact M-LINK and 1 x RX-7 DR M-LINK).
Information concerning suitability for two-receiver mode can be
found in the operating instructions provided with the various
M-LINK receivers.
This is the procedure for re-activating two-receiver mode:
! Note:
M-LINK receivers are set to two-receiver mode by default. For
this reason you can skip steps 1. – 3. and go directly to step 4.
! Caution: if one of the receiver's two "B/D" sockets is oc-
cupied by a diversity lead or a serial servo output lead, then this
lead must be disconnected from the receiver's "B/D" socket
before any programming or set-up work is carried out using a
MULTImate or MULTIPLEX Launcher!
1. Re-activating using the MULTImate:
At the menu point "4-7 B/D output" / "4-7 Ausgabe B/D"
(= output B/D) select the following option:
"MPX 2-Receiver" / "MPX 2-Empfänger"
(= MPX Two-receiver mode).
Select the menu point:
"4-10 Send data" / "4-10 Dat. senden" (= Send data)
and hold the 3-D digi-adjuster pressed in:
the MULTImate displays the following:
"please wait..." / "bitte warten..." (= please wait).
Release the 3-D digi-adjuster:
When the send process is complete, the screen
displays "--> OK!" (= complete!).
Disconnect the receiver, switch off the MULTImate.
