2.4Ghz - DMSS (JR)

Dual Modulation Spectrum System is JR’s own 2.4GHz protocol. A later entrant into the 2.4GHz market, DMSS can be considered as the truly ‘state of the art’ method of providing radio control for model use. And since JR have not rushed their own 2.4GHz protocol into production they have been able to incorporate the very latest techniques for ‘Wideband Data Transmission’ into the next generation of JR radio control sets.

DMSS combines the best features of Frequency Hopping Spread Spectrum (FHSS) and Direct Sequence Spread Spectrum (DSSS) protocols. FHSS is great for avoiding interference and DSSS offers high response. JR DMSS combines both these attributes, having both frequency hopping and high response.

The JR DMSS system uses a greater than 3Mhz wide signal as compared to the majority of others which utilise a much narrower [1Mhz or less] signal.

If we know anything about spread spectrum signals, a wider base signal [3Mhz Vs 1Mhz] allows for a huge increase in noise and interference immunity performance and at the same time allowing for much faster data bandwidth/throughput.

The fact that DMSS is actually using quite a wide bandwidth signal is a huge advantage in 2.4GHz performance and it will provide superior performance over any other current 2.4GHz system that is currently available.

DMSS also offers ‘Two-Way Communication’ (telemetry) with receiver voltage monitoring as standard. Other types of sensor are due soon, with Temperature and RPM sensors being the next types to become available from JR in late June.

Probably the most important thing about JR DMSS is that it is 100% pure JR, with no involvement from any other outside company. This means that JR are back in full control of product development, so they can now concentrate on doing what they do best – making what are arguably the world’s best quality radio control systems.

NOTE:  DMSS is not compatible with DSMX or DSM2 Receivers.

2.4GHz - DMX[2,X] Overview

DSMX builds upon the incredible DSM2 technology you have come to know and trust. After years of development and in the field use, DSMX is an evolution of DSM2 2.4 GHz technology, destined to deliver the most robust, reliable, and efficient level of RF link possible in the modeling world today.

DSMX is for those modelers who enjoy attending mega events where large numbers of 2.4 systems are on at once. Another great part about all of this is the forward/backward compatibility of DSMX to DSM2 is such that no current technology becomes orphaned with the release of todays or future DSM transmitter products.

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.

1. To realize the full benefits of DSMX technology you must have both a DSMX Transmitter and a DSMX Receiver

1. DSM2 transmitters are compatible with DSMX receivers. Likewise, should you add-on to a DSMX transmitter, the DSM2 receivers you have now will be compatible with it.

1. Because DSM2 and DSMX share the same wide-band DSSS foundation, all Spektrum users will enjoy superior range, speed and precision whether theyre using DSM2 equipment, DSMX equipment or a combination of both.

1. The difference a DSMX system makes is 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 may find the DSM2 equipment they have now is all they will ever need.
   
   *A DSMX system refers to a DSMX transmitter in use with a DSMX receiver.
