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 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 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.
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 spektrumrc.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 Spektrum advantages
you already enjoy with DSM2. Want to know more about DSMX? Visit
