Multiplex HFMx M-LINK Manual De Instrucciones página 10

Good resistance to interference:
Typical interference sources in the model, such as electric
motors, and electronic devices such as speed controllers, petrol
engine ignition systems etc., have an interference spectrum
whose maximum frequency is significantly below the 2.4 GHz
range. It is virtually impossible for 2.4 GHz systems to suffer
interference from such sources, and this provides a further im-
provement in security.
Fast, accurate transmission:
MULTIPLEX M-LINK is a digital transmission system offering a
maximum of sixteen servo channels with a resolution of 12 bits
(3872 steps). Background noise has no effect on servo signal
accuracy right up to the limits of range. Resolution, centring
precision and with it general accuracy of control are at a con-
stant high level up to the effective limits of range. M-LINK's
digital encoding allows both HOLD and FAIL-SAFE to operate
very accurately. The servo pulse rate of 21 ms (16-channel mode)
can be reduced to 14 ms (12-channel mode - Fast Response).
Short transmitter aerial:
The short 2.4 GHz transmitter aerial is robust and easy to handle,
and it does not impinge on the pilot's field of vision.

6.1.: Determining the optimum location for the
HFMx M-LINK 2.4 GHz RF module
If you use a hand-held transmitter, the new RF module can be
attached directly to the transmitter case. If you prefer to use the
transmitter in a transmitter tray, the HFMx M-LINK 2.4 GHz RF
module can also be installed in or on the tray.
Please note the following when deciding on the location:
•
The RF module should be mounted in such a way that the
2.4 GHz aerial is as far forward as possible (towards the top
face of the transmitter). The 2.4 GHz aerial must not be
concealed or obstructed by the transmitter, as it needs to
have a "free view" of the model.
•
When the HFMx M-LINK 2.4 GHz RF module is installed, it
must be possible to rotate and tilt the aerial attached to the
module to ensure that the radiation pattern is as good as
possible ( 10.).
•
It must be possible to connect the DIN plug attached to the
RF module to the transmitter's Trainer socket when the mo-
dule is in place (check cable length!).
•
Ensure that the components of the RF module (case, aerial,
lead and plug) do not obstruct access to the transmitter's
switches, sliders and rotary controls, nor prevent the pilot
reading the transmitter screen.
•
If you wish to attach the RF module to the back of the trans-
mitter, if at all possible position it in the area protected by a
transport handle, to avoid the risk of mechanical stress on
the module when the transmitter is put down.

6.2.: Securing the HFMx M-LINK 2.4 GHz RF module
Our example illustrates the method of fixing the HFMx M-LINK
2.4 GHz RF module to the case of a PROFImc 4000 transmitter
(used hand-held). The same basic method can be used to attach
the RF module to or in a transmitter tray, or to a different type of
transmitter.
1. Stick the Velcro tape (loop side) to the recessed areas on the
back of the RF module:
2. Stick the Velcro tape (hook side) to the transmitter case in
the appropriate position:
3. Attach the HFMx M-LINK 2.4 GHz RF module to the trans-
mitter case:
