PPLICATION
The external HFMx M-LINK 2.4 GHz RF module is the ideal
solution if you wish to use the same MULTIPLEX transmitter and
switch frequently between the 35, 40, ... MHz band and the 2.4
GHz band; or alternatively if you just wish to use an older MUL-
TIPLEX transmitter on the 2.4 GHz band.
The 2.4 GHz RF module is connected to the transmitter's Trai-
ner socket, and can either be attached directly to the transmitter
or mounted in the transmitter tray. No modifications to the trans-
mitter of any kind are necessary.
The term "Trainer socket" used in these instructions refers to the MULTI-
PLEX multi-function socket fitted to the transmitter. Other names used
for it are: DIN socket, charge socket, PC port and Diagnosis socket.
The advantages:
•
Simple, rapid method of switching between 35, 40, ... MHz
(internal transmitter) and 2.4 GHz M-LINK, carried out
directly on the HFMx M-LINK 2.4 GHz RF module using
a switch.
•
Can be switched between full frequency range and limited
frequency range ("France" mode
•
Can be switched between 14 ms servo frame rate (Fast
Response) and 21 ms servo frame rate (
•
Integral SET button for activating Binding mode (
range-check mode (

Legal note: transmitting apparatus must only be set up
and operated on frequencies / transmission channels which
are approved for the country in which it is to be used.
!
Important: in particular countries the module may only
be used within a restricted frequency range.
In certain countries the operation of 2.4 GHz RC systems with
an output power of 100 mW EIRP is only permitted within a
restricted frequency range. For this reason the HFMx M-LINK
2.4 GHz RF module offers the option of limiting the frequency
range (

M-LINK is a transmission system designed by MULTIPLEX. It
operates on the 2.4 GHz ISM band, and exploits modern FHSS
technology (FHSS = Frequency Hopping Spread Spectrum).
Automatic RF channel management:
With this system it is no longer necessary for the operator to
select the RF channel manually (plug-in crystals, Synthesizer).
2.4 GHz Spread Spectrum systems automatically divide up the
frequency spectrum, and this eliminates the need for conven-
tional frequency monitoring. Same-channel interference (as is
possible on the 35, 40 ... MHz band) is virtually impossible. The
first time the system is used you just have to carry out a simple
binding procedure to link the transmitter to the receiver. From
this moment on the receiver only responds to the signals from
your specific transmitter.
FHSS technology:
The transmitter and receiver jump from channel to channel every
few milliseconds, maintaining the same rhythm; the data is
transmitted during a fraction of this period. The resultant brief
period of channel occupation minimises signal conflicts, and
suppresses interference. Even if data packets are lost on par-
ticular channels, the constant high-speed hopping to the next
channel makes any interruptions unnoticeable to the pilot.
Good data security / transmission security:
The enormous bandwidth available on 2.4 GHz makes it pos-
sible to transmit much greater quantities of data than is possible,
for example on the 35 MHz band. Digital modulation in con-
8.) and
junction with sophisticated error-checking in the receiver guaran-
tee outstanding data quality.
