Announcing the Latest Innovation from Spektrum
Spektrum launched the 2.4GHz RC revolution and remains the leader of it for one simple reason – RC is our sole focus. It’s why Spektrum has made more innovations in RC in the last 5 years than anyone else.
DSMX is just such an innovation. It is a new, frequency-agile evolution of Spektrum™ 2.4GHz technology that matches the consistently superior speed and data capacity of DSM2 with the most advanced frequency shifting algorithm to date. The result is the fastest, most precise response in heavily congested 2.4GHz environments you will find anywhere.
A Solid Foundation: Wideband DSSS
DSMX is built on the same foundation as DSM2—the superior on-channel interference resistance and coding gain of wideband 2.4GHz DSSS technology. Compared to the wideband signal of a DSM2™ or DSMX™ system, the narrow-band signal of other 2.4 transmitters is more likely to suffer crucial data loss in the event of on-channel interference. Think of wideband 2.4 as a river and narrow-band 2.4 as a stream. It takes much more interference to stop a river than it does to stop a stream.
The big reason wideband is so robust is coding gain. Essentially what this means is that the unique coding in a DSM2 or DSMX wideband signal allows it to be heard well above the noise of surrounding 2.4GHz signals without requiring any more power. In fact, a Spektrum wideband signal can achieve as much as 3X the range of its narrow-band competition using the same amount of power.
The ‘X’-tra Benefit of Agility
What DSMX adds to the tried and true wideband technology of DSM2 is the extra interference protection and faster reconnection times of frequency agility. But DSMX is anything but a common frequency hopping system.
Agile: quick and well-coordinated in movement
DSMX frequency shifts are coordinated using the most advanced spread spectrum algorithm ever seen in an RC application. Unlike other FHSS transmitters that all hop in the same fixed patterns, every DSMX transmitter has its own unique frequency shift pattern calculated using its GUID (Globally Unique Indentifier). And each pattern uses just 23 channels in the 2.4GHz spectrum.
By adding the agility of unique frequency shifts to the superior interference-resistance of a wideband signal, and limiting those shifts to a smaller portion of the 2.4 band, DSMX transmitters provide quicker reconnection times and superb response in the noisiest 2.4GHz environments.
3D Spread Spectrum
In addition to its wideband DSSS foundation and smarter frequency agile protocol, DSMX users will enjoy a third dimension of signal protection that DSM2 users have always enjoyed. Only Spektrum full-range receivers offer the patented advantage of MultiLink™ dual-path redundancy. When combined with the superior wideband power and frequency agility of DSMX, MultiLink gives RC pilots the fastest, most reliable 2.4 RC technology available in any signal environment.
Just How Good is DSMX?
In multiple tests, 100 DSMX systems were operated simultaneously for extended periods of time. During these tests not a single case of RF link loss, latency increase or control degradation was experienced or recorded.
See the 100 transmitter test for yourself. Go to spektrumrc.com and watch the DSMX video.
Is DSM2 and DSMX equipment compatible?
Yes! DSM2 transmitters are forward compatible with DSMX receivers and DSMX transmitters are backward compatible with DSM2 receivers. And because DSM2 and DSMX share the same wideband DSSS foundation, all Spektrum users will enjoy superior range, speed and precision whether they’re using DSM2 equipment, DSMX equipment or a combination of both.
It is important to note, however, that the only way to experience the full benefits of DSMX (wideband DSSS plus frequency agility) is by pairing a DSMX transmitter with a DSMX receiver.
Are DSM2 Transmitters eligible for a DSMX add-on?
Yes, but the difference a DSMX system makes is really only apparent when hundreds of 2.4GHz systems are in use at once. DSM2 users who rarely, if ever, fly in big events or other exceptionally “noisy” 2.4GHz environments will find the DSM2 equipment they have now is all they will ever need. In typical RC environments like the local flying club or the neighborhood park, DSM2 is still consistently faster, more robust and more precise than any other narrow-band 2.4GHz solution.
DX8 owners who wish to get the DSMX add-on can simply download Spektrum AirWare™ v2.0 from spektrumrc.com and update the firmware using their SD card. All other DSM2 transmitters are eligible for the DSMX add-on for a fee of $75. Please visit horizonhobby.com for details. DSM2 receivers and transmitter modules are not eligible for the DSMX add-on.
DSM2 transmitter owners interested in making the move up to DSMX should visit spektrumrc.com for complete details on requesting the add-on.
Does DSMX have ModelMatch™ and ServoSync™?
Yes. DSMX will provide users with these and the many other exclusive Spektrum advantages they already enjoy with DSM2.
