PECIAL EATURES
High-quality 7-channel / 9-channel receivers assembled
using the latest SMT methods, exploiting MULTIPLEX
2.4 GHz M-LINK technology, suitable for all types of model.
Dual receivers:
Each receiver features two complete reception circuits
working in parallel (receiver diversity).
This ensures excellent reception quality by minimising
directional effects.
Supplementary signal pre-amplification:
For highest possible sensitivity.
In-line connector arrangement:
Ideal for models with limited internal space.
HOLD / FAIL-SAFE function.
Integral SET button and LED:
For binding, FAIL-SAFE programming, RESET and
displaying operating status information.
Telemetry / feedback channel capability:
Receiver battery voltage and connection quality
= standard features.
Integral sensor interface for connecting external sensor
modules.
Prepared for two-receiver operation:
Diversity lead (# 8 5070) required.
Integral error counter / data logger:
For voltage and signal errors.
Compatible with the MULTImate (# 8 2094).
Integral PC interface:
Carry out updates and change settings using the
RX DataManager PC program.

PPLICATIONS
The RX-7-DR M-LINK and RX-9-DR M-LINK 2.4 GHz receivers
(abbreviated to RX-7/9-DR M-LINK in this document) are radio
control receivers intended exclusively for use in model sport. It is
9
prohibited to employ them for other purposes such as full-size
(people-carrying) vehicles or industrial installations.
5. C
OMPATIBILITY
RX-7/9-DR M-LINK 2.4 GHz receivers can only be operated in
conjunction with transmitters which utilise MULTIPLEX M-LINK
transmission technology.
These are as follows (correct as of February 2010):
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.
! *Note:
Unless stated otherwise, when this document refers to the
transmitter types ROYALevo, ROYALpro, and PROFImc 3010,
3030 and 4000, the terms refer to the 2.4 GHz M-LINK versions.
6. P
OWER
RX-7/9-DR M-LINK receivers work within a broad range of vol-
tages from 3.5 V ... 9.0 V, i.e. they can be used with receiver
batteries consisting of four to six NiXX cells or 2S LiPo / 2S LiIo.
! Note: if you intend to use a five-cell or six-cell NiXX battery,
or a 2S LiPo or 2S LiIo pack, it is essential to check that all the
servos, gyros and other components connected to the system
are approved for use with this higher operating voltage.
! Note: ensure that the power supply is adequate
A power supply system in good condition and of adequate capa-
city 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
defective, cables of inadequate cross-section, poor-quality
connectors or an overloaded or defective BEC system.
