Range: 2km LOS (Line Of Site) or more**
Telemetry range – 400m. LOS or more**
Current consumption: 55mA
** Please note: Receiver range highly depends on your transmitter output power, environment conditions (weather, air
humidity, obstacles and metal structures), antenna orientation. Presence of another signal sources (Wifi, FPV etc.) can
significantly affect the range and even completely block reception. These receivers were tested using DSMX transmitter with
18.9dBm(77.62mW) power and a standard 2.4gHz dipole antenna on it. The range of stable reception was 2km
“ground-to-ground”. The range of stable telemetry data was 400m “ground-to-ground”. Ground-to-Air conditions (LOS)
typically give better range than “ground-to-ground”.
The R620X – R1220X incorporates diversity antennae, offering the security of dual path RF redundancy
By locating these antennae in slightly different locations in the aircraft, each antenna is exposed to its own RF environment,
greatly improving path diversity (the ability for the receiver to see the signal in all conditions).
In gas and glow aircraft install the main receiver using the same method you would use to install a conventional receiver in
your aircraft. Typically, wrap the main receiver in protective foam and fasten it in place using rubber bands or hook and loop
straps. Alternately, in electric airplanes or helicopters, it’s acceptable to use thick double-sided foam tape to fasten the receiver
in place. Mounting receiver antennae and satellites (if used) in slightly different locations, gives tremendous improvements in
path diversity. Essentially, each receiver/satellite sees a different RF environment and this is key to maintaining a solid RF link,
even in aircraft that have substantial conductive materials (e.g. larger gas engines, carbon fiber, pipes, etc.), which can
weaken the signal.
The receiver can initiate binding when powered ON with a bind plug installed in Bind connector or automatically after time out
depending on settings set by using Programming Card.
1. Binding by BIND plug: Install a bind plug into BIND connector. In case if you want to disable telemetry function on the
receiver, install second bind plug into THRO connector.
Apply power to the receiver. It can be from 3.7 to 9.6 volts DC. Please refer to picture on the side of the receiver for the correct
pinout (GND, VCC, SIGNAL)
You will see the orange LED rapidly blinking. That means the receiver is in Bind mode.
Follow the procedures of your specific transmitter to enter Bind Mode, the system will connect within a few seconds. Once
connected, the orange LED on the receiver will blink several times and go solid indicating the system is connected.
Remove the bind plug from the BIND port on the receiver before you power off the transmitter and store it in a convenient place.
2. Binding by timeout. In autobind settings user can set the time when the receiver enters autobind mode if no signal from already
known (bound) transmitter is available. Available settings:
• Autobind OFF – Receiver never enters autobind mode. To avoid accidental binding with transmitter nearby please use this
mode when possible.
• Autobind 30 (60, 120)sec. – select timeout when receiver will enter an autobind mode. Please use this mode carefully. In
autobind mode receiver blinks red LED indicating this mode before it enters binding.
Please note: Autobind is a useful feature but user has to follow safety procedures: Never keep your model turned ON
without presence of your transmitter signal unless you want to bind your receiver and transmitter. If you want to do so
for some particular reasons make sure that you switched Autobind OFF
NOTICE:
Remove the bind plug to prevent the system from entering bind mode the next time the power is turned on.
The R620X – R1220X features advanced failsafe. After missing transmitter signal for 1 second the receiver enters failsafe
mode. The channels states can be preprogrammed to make model act the safest way. There are several options for reaction in
failsafe:
• no packet – no output signals on servo channels at all.
• on bind – servo channels values will be same as coming from transmitter during binding
• all 1500 – all channels except throttle are 1500ms. Throttle is 1003ms(min)
• set current – remembers the values currently coming from the Programming Card (ID: 9171001376-0, sold separately).
This option is used in conjunction with Channels Menu. In channels menu you can set desirable values for your failsafe.
After this you can go to Failsafe menu and choose “set current”. The card will ask to store values. After confirmation the
values that currently set in Channels menu will be stored as failsafe values (Please refer to the Programming Card manual
for details).
When the receiver only is turned on (no transmitter signal is present), the throttle channel has no output, to avoid operating or
arming the electronic speed control. All other channels are driven to their preset failsafe positions set during binding.
Sometimes a short power loss happens in the flight. It can happen if your BEC is not powerful enough and servos consume
high current or receiver pack is weak or discharged. It causes a short voltage drop. The event when receiver suddenly loses
power in the flight is called a brownout. When power comes back it takes time for the receiver to reconnect to transmitter.
During this time (up to 1 second, depends on the environment conditions) some analog servos may coast to their extremes
even though no signal is present. This may lead to crash due to unexpected servo moves. To avoid this a new feature Fast
Brownout Recovery is introduced. With this feature analog servos will have only a minor glitch during the recovery time.
For bigger aircrafts, 600 and more size helicopters, gas aircrafts or long range projects you don’t want to give a chance for a
signal loss. To improve the reception and reduce risks of signal loss you can attach up to two satellite receivers to the main
receiver. Using two additional OrangeRx R110XL 2.4Ghz Satellite Receivers you will get 6(six!!) antennae receiving the
signal
at the same time. The antennae should be oriented in different directions and satellites placed at the different sides of
the aircraft.
For optimum RF link performance it’s important that the antennae be mounted in an orientation that allows for the best possible
signal reception when the aircraft is in all possible attitudes and positions. This is known as antenna polarization. The antennae
should be oriented perpendicular to each other; typically vertical and horizontal and at different angles.
After you’ve set up your model, it’s important to rebind the system so the true low throttle and neutral control surface positions
are set.
