Spektrum launched the 2.4GHz RC revolution with its DSM2
technology. Since then millions of hobbyists the world over have
come to embrace 2.4 as the way to fly. Spektrum leads the way
yet again with DSMX; the world’s first wideband, frequency-agile
2.4GHz signal protocol.

How Does DSMX Work?
It’s a crowded 2.4GHz world out there and every 2.4GHz system
faces the same challenges. DSMX better equips you for these
challenges by combining the superior data capacity and interfer-
ence resistance of a wideband signal (like that used in DSM2)
with the agility of frequency shifts.
faces the same challenges. DSMX better equips you for these
challenges by combining the superior data capacity and interfer-
ence resistance of a wideband signal (like that used in DSM2)
with the agility of frequency shifts.
Compared to the wideband signal of DSMX, the narrow band
signal of other frequency hopping 2.4 transmitters is more likely
to suffer data loss in the event of on-channel interference. Think
of it as a river vs. a stream. It takes more interference to dam a
river than it does a stream.

river than it does a stream.
As more and more 2.4 transmitters vie for the same number
of available channels, there is more interference and more of a
risk for data loss. By adding the agility of frequency shifts to the
superior interference resistance of a wideband signal, DSMX
is far less likely to suffer significant data loss from on-channel
interference. The result is quicker connection times and superior
response in even the most crowded 2.4GHz environment.

NOTICE: While DSMX allows you to use more than 40 transmit-
ters simultaneously, when using DSM2 receivers, DSMX receiv-
ers in DSM2 mode or transmitters in DSM2 mode, do not use
more than 40 transmitters simultaneously.

DSMX Operational Differences
DSMX transmitters and receivers function nearly identically to
Spektrum DSM2 systems. Binding, setting the failsafe, recording
flight log data, as well as general use of the system is no differ-
ent than using any current Spektrum system.

Following are the operational differences:
Brownout Detection- Not Available on DSMX Receivers,
DSM2 receivers feature Brownout Detection that flashes the
receiver’s LED if a power interruption occurs. While DSMX
receivers have QuickConnect™ and recover instantly from a
power interruption, the architecture of DSMX prevents Brownout
Detection when operating in DSMX mode.

Flight Log Recording- Fades Higher than DSM2
Note that DSMX hops through the band while DSM2 finds two
quiet channels and remains on those channels. Consequently
because DSMX operates on quiet and noisy channels, it’s com-
mon to have more Antenna Fades than when using DSM2, when
used in busy 2.4GHz environments. When taking flight log data
readings, the Frames and Hold Data are important and should be
used a reference while Fades are insignificant due to the nature
of frequency hopping. A 10-minute flight will typically result in
less than 50 Frame Losses and no Holds.

Just How Good is DSMX?
In multiple tests, 100 DSMX systems were operated simultane-
ously for extended periods of time. During these tests each of the
100 systems was monitored in flight and on the ground. In every
test not a single case of RF link loss, latency increase or control
degradation was experienced or recorded.

Is DSMX Compatible with DSM2?
Yes. DSMX is fully compatible with all DSM2 hardware. In fact,
many pilots may find the DSM2 equipment they have now is all
they will ever need. Even if a new DSMX transmitter eventually
comes along that they really want, all the DSM2 receivers they
have now will work with it.

It is important to note, however, that while DSMX is compatible
with DSM2, the only way to experience the full benefits of DSMX
in a busy 2.4 environment is by pairing a DSMX transmitter with
a DSMX receiver.

Can DSM2 Transmitters be Upgraded to DSMX?
Yes. DX8 owners can simply download Spektrum AirWare™ v2.0
software from spektrumrc.com and update the firmware using
their SD card. DX6i transmitters manufactured after October
2010 can be upgraded using instructions provided on spektrum-
rc.com. All other DX6i DSM2 transmitters can be upgraded for
$75 by sending them to the Horizon Hobby service center. DSM2
receivers and transmitter modules cannot be upgraded to DSMX.

Does DSMX have ModelMatch and ServoSync?
Yes. DSMX will provide you with these and other exclusive Spek-
trum advantages you already enjoy with DSM2.
