How QuickConnect Works
When the receiver voltage drops below 3.2 volts, the system drops out (ceases
to operate). When power is restored, the receiver immediately attempts to
reconnect. If the transmitter was left on, the system reconnects, typically about
4ms. The receivers then blink, indicating a brownout has occurred (DSM2 Only).
If at any time the receiver is turned off then back on and the transmitter is not
turned off, the receivers will blink, as a power interruption was induced by turning
off the power to the receiver (DSM2 Only).
CAUTION: If a brownout occurs in-flight, it is vital you determine the
cause of the brownout and correct it. QuickConnect and Brownout Detection
allow you to safely fly through most short duration power interruptions.
However, the root cause of these interruptions must be corrected before the
next flight to prevent catastrophic safety issues.
Flight Log (SPM9540 Optional)
The Flight Log is compatible with the AR10000. The Flight Log displays overall
RF link performance as well as the individual internal and external receiver link
data. Additionally it displays receiver voltage.
Using the Flight Log
After a flight and before turning off the receiver or transmitter, plug the Flight
Log into the BIND/DATA port on the AR10000. The screen will automatically
display voltage e.g. 6v2= 6.2 volts.
When the voltage reaches 4.8 volts or less, the screen will flash, indicating
low voltage.
Press the button to display the following information:
A - Antenna fades on the internal antenna
B - Antenna fades on the external antenna
L - Not used
R - Not used
F - Frame loss
H - Holds
Antenna fades—represents the loss of a bit of information on that specific antenna.
Typically it’s normal to have as many as 50 to 100 antenna fades during a flight. If any
single antenna experiences over 500 fades in a single flight, the antenna should be
repositioned in the aircraft to optimize the RF link.
Frame loss—represents simultaneous antenna fades on all attached
receivers. If the RF link is performing optimally, frame losses per flight should
be less than 20. A hold occurs when 45 consecutive frame losses occur.
This takes about one second. If a hold occurs during a flight, it’s important
to evaluate the system, moving the antennas to different locations and/or
checking to be sure the transmitter and receivers are all working correctly.
TIP: A servo extension can be used to allow the Flight Log to be plugged
in more conveniently. On some models, the Flight Log can be plugged in,
attached and left on the model using double-sided tape. Mounting the Flight
Log conveniently to the side frame is common with helicopters.
ModelMatch ™
Some Spektrum and JR transmitters 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 screen.
IMPORTANT: 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.
Please note that the DX5e and Aircraft Modules do not have ModelMatch.
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 first, the transmitter or the receiver?
A: It doesn’t matter, although it is suggested to turn the transmitter on first.
If the receiver is turned on first, the throttle channel doesn’t put out a
pulse position at this time, 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 DSM2 systems will acquire two
open channels while DSMX systems will begin transmission after being
turned on. Then the receiver that was previously bound to the transmitter
scans the band andfinds the GUID (Globally Unique Identifier code) stored
during binding. Thesystem then connects and operates normally. If the
transmitter is turned on first, the transmitter scans the 2.4GHz band and
DSM2 systems acquire two open channels while DSMX systems will
simply begin transmission. When the receiver is turned on, the receiver
scans the 2.4GHz band looking for the previously stored GUID. 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 continuous (one after the other)
uninterrupted perfect packets from the transmitter. 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 feet) or if the transmitter is located near metal objects (metal
transmitter case, the bed of a truck, the top of a metal work bench, etc.)
connection will take longer. In some cases connection will not occur
as the system is receiving reflected 2.4GHz energy from itself and is
