SPECIAL FEATURES • High-quality 5-channel / 7-channel receivers assembled using the latest SMT methods, exploiting MULTIPLEX 2.4 GHz M-LINK technology. • Supplementary signal pre-amplification: For maximum sensitivity and great range. • In-line connectors arranged on the front and back: Ultra-compact dimensions: suitable for models with very little 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 via MSB (MULTIPLEX Sensor Bus). • Prepared for two-receiver operation: Diversity lead (# 8 5070) required. • Prepared for serial servo output: Servo outputs as sum signal – SRXL-MULTIPLEX. The receiver’s first twelve channels are carried by a three- cord lead (# 8 5070) via the receiver’s B/D socket, e.g. for power supply / servo management systems, or for flybarless systems in model helicopters. • Prepared for selecting one sensor address as “priority address”: The selected sensor value is updated at a faster rate than all the other sensor values. • Integral error counter / data logger: For voltage and signal errors. • Compatible with the MULTImate (# 8 2094). • Integral PC interface: Carry out updates and adjustment using the MULTIPLEX Launcher PC program in conjunction with the UNI USB PC lead (# 8 5149). 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 13.). ! Carry out regular range checks (Î 14.). 4. APPLICATIONS The RX-5 M-LINK and RX-7 M-LINK 2.4 GHz receivers (abbre- viated to RX-5/7 M-LINK in this document) are radio control receivers intended exclusively for use in model sport. It is prohibited to employ them for other purposes such as full-size (people-carrying) vehicles or industrial installations. Typical applications for RX-5 M-LINK and RX-7 M-LINK re- ceivers: • Gliders and electric gliders up to about 2.50 m wingspan • Small to medium-sized RC helicopters with rotor diameters up to about 1 m • Model aircraft with electric and I.C. power systems and wingspans up to about 1.60 m • RC model cars • RC model boats 5. COMPATIBILITY RX-5/7 M-LINK 2.4 GHz receivers can only be operated in con- junction with transmitters which utilise MULTIPLEX M-LINK transmission technology. As of April 2011 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. • Graupner/JR transmitters with any of the following 2.4 GHz RF modules: HFMG1 M-LINK, HFMG2 M-LINK or HFMG3 M-LINK. ! * 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. POWER SUPPLY RX-5/7-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 (LiXX). Operating Instructions for RX-5 M-LINK / RX-7 M-LINK 2.4 GHz receivers Page 12 Instructions for RX-5/7 M-LINK 2.4 GHz receivers # 985 5312 (11-05-18/MIWA) • Errors and omissions excepted! • © MULTIPLEX ! 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. 7.
