M-LINK is a new radio transmission system from MULTIPLEX. It operates on the 2.4 GHz ISM band, and is based on modern Frequency Hopping Spread Spectrum technology.
The features of M-LINK are as follows:
• Automatic RF channel management
The need for the user to change the RF channel (plug-in crystals, Synthesizer) manually is eliminated. 2.4 GHz Spread Spectrum systems divide up the frequency spectrum automatically, and for this reason conventional frequency monitoring control is no longer needed. Interference due to “channel clashes” (as is possible on the 35, 40 … MHz bands) is virtually eliminated.
When the system is first used, all you have to do is “bind” the transmitter and receiver using a simple binding procedure. Once this is done, the receiver only recognises and processes the signals broadcast by its own transmitter.
• Fast, accurate transmission of up to sixteen servo channels
Depending on the transmitter in use, the new MULTIPLEX M-LINK standard transmits:
- twelve servo channels at 14 ms pulse rate
- sixteen servo channels at 21 ms pulse rate
at 12-bit resolution (3872 steps)
• Feedback capability / Telemetry
The 2.4 GHz ISM band provides the means of transmitting data from the model back to the transmitter. The receiver in an M-LINK system transmits the voltage of the receiver power supply to the transmitter in real time. If the voltage falls to a dangerous level, the transmitter generates a warning signal to alert the user. Additional external sensors (e.g. voltage, current, temperature) can also be connected to M-LINK receivers designed for this facility.
• Diversity and dual-receiver operation
MULTIPLEX M-LINK DR (Dual Receiver) receivers are of very sophisticated construction, and feature two complete receiving circuits in one case (receiver diversity). Both circuits receive constantly, and the circuit compares the signal quality; at any one time the better signal is selected for further processing, and is passed on to the servo outputs with zero delay. If reception conditions are critical, and / or the model is particularly valuable, two receivers can be coupled together in the model; this minimises signal reflections and polarisation effects which are typical of 2.4 GHz, and represents the highest possible level of security.
• Frequency Hopping Spread Spectrum technology (FHSS)
The transmitter and receiver jump (hop) from channel to channel at the same rhythm, at intervals of just a few milli-seconds. The control data is actually transmitted during a fraction of this time. It is this brief period of occupation of each channel which minimises signal conflicts and suppresses interference. Even if individual data packets are lost on individual channels, the constant high-speed process of hopping from channel to channel renders the interruption invisible to the pilot.
• Great range
The MULTIPLEX M-LINK system exploits the Frequency Hopping Spread Spectrum (FHSS) process. The radiated power approved for this system is 100mW EIRP, and in practice this results in radio range of more than 2000 m on the ground. In the air the effective range is even higher due to the more favourable propagation conditions. In simple terms this means an ample margin
of safety, even for large-scale models.
• High data transmission security
The enormous bandwidth available on 2.4 GHz makes it possible to transmit much greater quantities of data than is possible, for example, on the 35 MHz band (bandwidth 2.4 GHz = 83.5 MHz; 35 MHz = 1 MHz). Digital modulation in conjunction with sophisticated error-checking and correction in the receiver ensure excellent data quality.
• High resistance to interference
Typical interference sources in the model, such as electric motors, electronic devices such as speed controllers, ignition units for internal combustion engines etc., generate interference over a spectrum whose maximum frequency is far below the 2.4 GHz range. This simply means that 2.4 GHz systems are virtually immune to interference from these sources, and this results in a
further improvement in safety.
• HOLD / FAIL-SAFE function
If the receiver detects data which has suffered interference and is irreparable, it passes on the last valid data to the servos, thereby bridging the period of the signal loss (HOLD mode).
If interference continues beyond the (variable) HOLD period, FAIL-SAFE is activated, i.e. the receiver moves the servos to a programmable safety position (e.g. throttle off, control surfaces neutral). The FS positions are stored using a push-button at the receiver; some transmitters include a menu for this, enabling the Fail-Safe positions to be set “by radio”.

• Short transmitter / receiver aerials
The typically short 2.4 GHz transmitter aerials are more robust and easier to handle than conventional telescopic aerials, and they also do not interfere with the pilot’s field of view. Short receiver aerials are much easier to install in the model.
• High vibration resistance
Small, modern, highly integrated transceiver ICs replace ceramic components, coils and filters, all of which are susceptible to damage from vibration.
• Ready for LiPo
All MULTIPLEX M-LINK receivers feature a wide operating voltage range of 3.5 - 9.0 V, and are therefore largely immune to collapses in the power supply voltage. They are prepared for use with 2S LiXX batteries without voltage stabilisation to (typically) 6.0 V.
• World-wide approval
Apparatus operating on the 2.4 GHz band can be used world-wide. The components of the MULTIPLEX M-LINK system fulfil all current directives and statutory requirements.
• Update-capable
All transmitters and receivers are equipped with modern Flash memory micro-controller technology, and can therefore be updated at any time. This means that system components can be brought up to the latest state of software development when technical innovations are introduced in the future, or when changes are made to regulations

COCKPIT SX M-LINK

The COCKPIT SX is a very popular, proven seven-channel RC system intended for the ambitious beginner and demanding weekend pilot, and it is now available with the new MULTIPLEX 2.4 GHz M-LINK technology for even greater convenience and security.
The new system includes all the product characteristics and features of the COCKPIT SX:
• Seven fully proportional control channels
• Twelve model memories
• Wide-ranging mixer and set-up facilities for fixed-wing models and helicopters
• Two timers and separate transmitter operating timer
• Generously sized, clearly arranged screen, carefully designed menu structure and 3-D digi-adjuster for ultra-simple operation.
• Fully expanded as standard, including all controls and switches
• Digital trims, specific to each flight phase
• MULTIPLEX multi-function socket fitted as standard: transmitter battery charge socket, Trainer socket, PC interface for firmware updates, data management and simulator operation
• Modern, ergonomically efficient case design
A detailed description of the COCKPIT SX can be found in our current main catalogue, or on our website at www.multiplex-rc.de!
The new, additional advantages are as follows:
• Integral M-LINK 2.4 GHz transmission technology
A menu is provided as an easy and convenient means of activating the special operating modes of Binding and Power Reduction (for range-checking). This eliminates the need to operate buttons which may be difficult to reach or use.
• Feedback channel / Telemetry
If you use a receiver with telemetry facilities (min. RX-7-DR M-LINK or RX-9-DR MLINK), the actual voltage of the receiver power supply is displayed on the transmitter screen. If the voltage falls below a (variable) minimum value, an audible warning signal alerts you that your receiver battery is almost flat. This means that you are constantly aware of the state of the receiver battery, as well as the condition of the transmitter battery (as previously). An important extra safety feature!
• Low latency, high resolution
The COCKPIT SX features an integral RF module. Unlike many other 2.4 GHz transmitters or retro-fit modular solutions, this means that the data does not have to be converted from conventional PPM or PCM format to the digital 2.4 GHz transmission format. The net result is that the system is capable of transmitting high-resolution, accurate control signals at very high speed. The COCKPIT SX M-LINK operates with a servo pulse rate of 14 ms and 12-bit resolution (3872 steps).

TIP:
If you already own a COCKPIT SX, you can easily transfer your model data to the new COCKPIT SX M-LINK using the COCKPIT SX DataManager PC program!
