DSMX
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 interference 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.
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.
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 different 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
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 common 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 simultaneously 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.
Are DSM2 Transmitters Eligible for a DSMX Add-on?
Yes. DX8 owners can simply download Spektrum AirWare
™
software from
spektrumrc.com and update the firmware using their SD card. All DSM2
transmitters, except the DX5e, are eligible for the add-on by going to
https://community.spektrumrc.com/ for details. DSM2 receivers and transmitter
modules are not eligible for the DSMX add-on.
™
Does DSMX have ModelMatch
and ServoSync™?
Yes. DSMX will provide you with these and other exclusive Spektrum advantages
you already enjoy with DSM2. Want to know more about DSMX? Visit spektrumrc.
com for complete details on this as well as the many other reasons Spektrum is the
leader in 2.4.
Note: DSMX receivers are not compatible with DSM2 remote receivers and DSM2
receivers are not compatible with DSMX remote receivers.
• DSMX transmitters are compatible with all DSM2 and DSMX receivers and will
operate in the mode noted in the chart.
• DSM2 transmitters are compatible with all DSM2 and DSMX receivers and will
operate in the mode noted in the chart.
• DSMX technology is active only when both transmitter and receiver are DSMX
enabled.
Note 1: DSMX upgraded DX5e and DX6i transmitters are compatible with all
DSMX receivers except the high-speed DSM2 receivers (like the AR7600, AR9000,
etc.). When using a high-speed DSM2 receiver with the DX5e or DX6i, it’s necessary to manually put these transmitters into DSM2 mode. See the Spektrum website
for details on DX5e/DX6i DSM2 mode for details.
