2. SPECIAL FEATURES
• Small, all-purpose 6-channel / 7-channel receiver exploiting
MULTIPLEX 2.4 GHz M-LINK technology, ideal for use in
small models.
• Dual receiver:
The receiver contains two complete receiving circuits which
operate in parallel (receiver diversity).
This provides excellent reception quality by minimising
directional effects.
• In-line connector arrangement:
Ideal for use even in slender fuselages (e.g. F3B, F3J, …).
• HOLD / FAIL-SAFE function.
• Integral SET button and LED:
For binding, FAIL-SAFE programming, RESET and
operating status information.
3. SAFETY NOTES
! Please read the instructions before using the receiver.
! Use the receiver only for the intended applications
(
Î 4.).
! Ensure the power supply is of adequate capacity (
Î 6.).
! Observe the installation notes (Î 9.).
! Carry out regular range checks (
Î 10.).
4. APPLICATION
The RX-6/7-DR light M-LINK is a radio control receiver inten-
ded exclusively for use in model sport applications. It is prohi-
bited to use it for other applications, such as man-carrying
vehicles or industrial installations.
The RX-6/7-DR light M-LINK was designed with minimum
possible size and weight as top priority, and for technical rea-
sons such a unit cannot offer the same reception characteristics
as a larger, technically more sophisticated and more expensive
receiver. In the interests of safety we recommend that you use a
larger receiver wherever space permits. However, under normal
conditions it is possible to obtain an excellent reception perfor-
mance with the RX-6/7-DR light M-LINK provided that all the
RC components are arranged carefully, and the two receiver
aerials are deployed correctly.
5. COMPATIBILITY
The RX-6/7-DR light M-LINK 2.4 GHz receiver can only be used
in conjunction with transmitters which use MULTIPLEX M-LINK
transmission technology. As of June 2009 these are:
• ROYALpro 7, 9 and 16 M-LINK.
• ROYALevo or pro 7, 9 and 12 with firmware version V3.xx
and the HFM4 M-LINK 2.4 GHz RF module.
• PROFImc 3010, 3030 and 4000 with the HFM3 M-LINK
2.4 GHz RF module.
• COCKPIT SX M-LINK.
• MULTIPLEX transmitters with the HFMx M-LINK 2.4 GHz
RF module.
6. POWER SUPPLY
The
RX-6/7-DR light M-LINK
receiver works with a wide range
of voltages from 3.5 V … 9.0 V, i.e. with receiver batteries con-
sisting of 4 to 6 NiXX cells or 2S LiPo / 2S LiIo batteries.
! Note: if you wish to use a five-cell (six-cell) NiXX battery,
check that all the servos, gyros and other components to be
connected to the system are approved by the manufacturer for
use on operating voltages up to 7.5 V (9.0 V). If you wish to use
a 2S LiPo (2S LiIo) pack, check that all the servos, gyros and
other components to be connected to the system are approved
by the manufacturer for use on up to 8.4 V (8.2 V).
! Note: ensure that the power supply is adequate
A power supply system in good condition and of adequate
capacity for the specific application plays an indispensable role
in the safe operation of any model:
• Use only high-quality receiver batteries of adequate capacity.
Balance and maintain them carefully, and charge them fully.
• Ensure that all cables are of adequate conductor cross-
section. Keep all wiring as short as possible, and use the
absolute minimum of plug / socket connections.
• Use high-quality switch harnesses exclusively.
• Brief collapses in the power supply voltage (lasting a few
milli-seconds) have no adverse effect on the receiver. Longer
voltage collapses to below 3.5 V may cause a receiver reset,
resulting in a brief interruption in reception. This may be due
to a receiver battery which is almost flat, too weak or defec-
tive, cables of inadequate cross-section, poor-quality con-
nectors or an overloaded or defective BEC system.
