Spectrum AR6300 User manual

Servo Connectors
The AR6300 uses JST micro connectors offering the lightest and most compact installation. Note that
servos must have micro JST-type connectors to be compatible with the receiver. Note that some JST-
type servos have a different polarity than Spektrum servos. See photo for correct connector polarity.
Plugging In the Leads
Plug the servo leads into the appropriate servo ports in the receiver noting the polarity of the servo
connector.
Binding
The AR6300 receiver must be bound to the transmitter before it will operate. Binding is the process
of teaching the receiver the specific code of the transmitter so it will only connect to that specific
transmitter.
1. To bind an AR6300 to a DSM2 transmitter, with the power off, short the bind pins together with tweezers,
hemostat or small needle-nose pliers.
2. Power on the receiver. If the receiver is installed in an electric aircraft, turn on the speed controller
to power up the receiver. If the receiver is going to be powered by a separate battery, plug the battery
into any unused port. The amber light will blink, indicating the AR6300 is in bind mode.
3. Position the transmitter’s control sticks and switches in the desired failsafe positions (normally low
throttle and all other controls at neutral).
4. Follow the procedures of your specific transmitter to enter Bind Mode; the system will connect
within a few seconds. Once connected, the LED on the receiver will go solid indicating the system
is connected.

Receiver Installation
The AR6300 Nanolite receiver is designed for micro light, foam and slow flyer aircraft. Use double-
sided foam tape to mount the receiver in place.
5. 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.
ModelMatch™
Some Spektrum transmitters (such as the DX7) offer a patent pending feature called ModelMatch.
ModelMatch prevents the possibility of operating a model using the wrong model memory, potentially
preventing a crash. With ModelMatch each model memory has its own unique code (GUID) and during
the binding process the code is programmed into the receiver. Later, when the system is turned on, the
receiver will only connect to the transmitter if the corresponding model memory is programmed on
the screen.
Note: If at any time you turn on the system and it fails to connect, check to be sure the correct model
memory is selected in the transmitter.
SmartSafe™ Failsafe
Your AR6300 features SmartSafe failsafe programming. SmartSafe prevents accidental motor operation
before the system connects and, in the unlikely event of signal loss, SmartSafe drives the throttle to a
preset (off) position. With SmartSafe, if the receiver is turned on before the transmitter, all channels but
throttle will go to their failsafe positions stored during binding. The throttle channel will not generate
a pulse so as to not arm the electronic speed control. After the system is connected, if loss of signal
occurs, the throttle will be driven to a preset failsafe position, normally low throttle (set during binding)
while all other channels will hold their last known position.
Range Check
Before each flying session and especially with a new model, it is important to perform a range check.
Follow the procedures as outlined in the radio instruction manual.
Receiver Power System Requirements
Inadequate power systems that are unable to provide the necessary minimum voltage to the receiver
during flight have become the number one cause of in-flight failures. Some of the power system
components that affect the ability to properly deliver adequate power include:
• Receiver battery pack (number of cells, capacity, cell type, state of charge)
• The ESC’s capability to deliver current to the receiver in electric aircraft
• The switch harness, battery leads, servo leads, regulators, etc.
The AR6300 has a minimum operational voltage of 3.5 volts. If the voltage drops below 3.5 volts
the system will connect when power is restored and the LEDs will flash indicating a brownout. See
QuickConnect below.
Recommended Power System Test Guidelines
If a questionable power system is being used (e.g. small or old battery, an ESC that may not have a
BEC that will support current draw, etc.), it is recommended that a voltmeter be used to perform the
following tests.
Plug the voltmeter into an open channel port in the receiver and with the system on, load the control
surfaces (apply pressure with your hand) while monitoring the voltage at the receiver. The voltage
should remain above 4.8 volts even when all servos are heavily loaded.
QuickConnect™ With Brownout Detection
Your AR6300 features QuickConnect with Brownout Detection.
• Should an interruption of power occur (brownout), the system will reconnect immediately when
power is restored (QuickConnect).
• The LED on the receiver will ash slowly indicating a power interruption (brownout) has occurred.
• Brownouts can be caused by an inadequate power supply (weak battery or regulator), a loose
connector, a bad switch, an inadequate BEC when using an Electronic speed controller, etc.
• Brownouts occur when the receiver voltage drops below 3.5 volts thus interrupting control as the
servos and receiver require a minimum of 3.5 volts to operate.
How QuickConnect With Brownout Detection Works
• When the receiver voltage drops below 3.5 volts the system drops out (ceases to operate).
• When power is restored the receiver immediately attempts to reconnect to the last two frequencies
that it was connected to.
• If the two frequencies are present (the transmitter was left on) the system reconnects typically in
about 4/100 of a second.
QuickConnect with Brownout Detection is designed to allow you to y safely through most short
duration power interruptions, however, the root cause of these interruptions must be corrected before
the next flight to prevent a crash.
Note: If a brownout occurs in flight it is vital that the cause of the brownout be determined and corrected.
Tips on Using Spektrum 2.4GHz
While your DSM-equipped 2.4GHz system is intuitive to operate, functioning nearly identically to
72MHz systems, following are a few common questions from customers.
1. Q: Which do I turn on rst, the transmitter or the receiver?
A: If the receiver is turned on first—all servos except for the throttle will be driven to their preset
failsafe positions set during binding. At this time the throttle channel doesn’t output a pulse
position preventing the arming of electronic speed controllers or in the case of an engine
powered aircraft the throttle servo remains in its current position. When the transmitter is
then turned on the transmitter scans the 2.4GHz band and acquires two open channels. Then
the receiver that was previously bound to the transmitter scans the band and finds the GUID
(Globally Unique Identifier code) stored during binding. The system then connects and
operates normally.
If the transmitter is turned on first—the transmitter scans the 2.4GHz band and acquires two
open channels. When the receiver is then turned on for a short period (the time it takes to
connect) all servos except for the throttle are driven to their preset failsafe positions while the
throttle has no output pulse. The receiver scans the 2.4GHz band looking for the previously
stored GUID and when it locates the specific GUID code and confirms uncorrupted repeatable
packet information, the system connects and normal operation takes place. Typically this takes
2 to 6 seconds.
2. Q: Sometimes the system takes longer to connect and sometimes it doesn’t connect
at all?
A: In order for the system to connect (after the receiver is bound) the receiver must receive a large
number of consecutive uninterrupted perfect packets from the transmitter in order to connect.
This process is purposely critical of the environment ensuring that it’s safe to fly when the system
does connect. If the transmitter is too close to the receiver (less than 4 ft) or if the transmitter
is located near metal objects (metal Tx case, the bed of a truck, the top of a metal work bench,
etc.) connection will take longer and in some cases connection will not occur as the system is
receiving reflected 2.4GHz energy from itself and is interpreting this as unfriendly noise. Moving
the system away from metal objects or moving the transmitter away from the receiver and
powering the system again will cause a connection to occur. This only happens during the initial
connection. Once connected the system is locked in and should a loss of signal occur, (failsafe)
the system connects immediately (4ms) when signal is regained.
3. Q: I’ve heard that the DSM system is less tolerant of low voltage. Is that correct?
A: All DSM receivers have an operational voltage range of 3.5 to 9 volts. With most systems this is
not a problem as in fact most servos cease to operate at around 3.8 volts. When using multiple
high-current draw servos with a single or inadequate battery/power source, heavy momentary
loads can cause the voltage to dip below this 3.5-volt threshold thus causing the entire system
(servos and receiver) to brown out. When the voltage drops below the low voltage threshold
(3.5 volts), the DSM receiver must reboot (go through the startup process of scanning the band
and finding the transmitter) and this can take several seconds. Please read the receiver power
requirement section as this explains how to test for and prevent this occurrence.
4. Q: Sometimes my receiver loses its bind and won’t connect requiring rebinding.
What happens if the bind is lost in ight?
A: The receiver will never lose its bind unless it’s instructed to. It’s important to understand that
during the binding process the receiver not only learns the GUID (code) of the transmitter but
the transmitter learns and stores the type of receiver that it’s bound to. If the transmitter is placed
into bind mode, the transmitter looks for the binding protocol signal from a receiver. If no signal
is present, the transmitter no longer has the correct information to connect to a specific receiver
and in essence the transmitter has been “unbound” from the receiver. We’ve had several DX7
customers that use transmitter stands or trays that unknowingly depress the bind button and the
system is then turned on losing the necessary information to allow the connection to take place.
We’ve also had DX7 customers that didn’t fully understand the range test process and pushed the
bind button before turning on the transmitter also causing the system to “lose its bind.”
