Introduction

Spektrum’s Digital Spectrum Modulation (DSM) system offers the ultimate in radio link security. No longer do you have to worry about transmitters on your frequency unintentionally being turned on, waiting for the frequency clip to practice or interference caused from noisy motors, speed controllers or other interfering sources. The DSM system utilizes Digital Spread Spectrum technology providing an impenetrable radio link.

Operating within the ultra high frequency 2.4GHz worldwide ISM band, each individual module is programmed at the factory with its own unique serial code called GUID (Globally Unique Identiﬁcation code). Once a receiver is programmed to a speciﬁc module (called binding), the receiver will only recognize that module, ignoring signals from any other sources. And with over 4 billion possible GUID codes, it’s virtually impossible for a receiver to listen to anything other than its bound transmitter.

The DSM system is telemetry-ready for optional telemetry modules (purchased separately). Engine temperature, speed, rpm, signal strength, battery voltage and even lap times are displayed in real time via Spektrum’s handheld display or via a PC. Telemetry options will be updated periodically to include a wide variety of popular functions.

Benets

• Eliminates the possibility of interference from an unintentional turn-on

• Impervious to model-generated RF interference (like noisy motors, speed controllers,

metal-to-metal noise, etc.)

• Robust interference from any outside sources like other transmitters, cell phones,

pagers, WiFi systems, etc.

• No more waiting for an open frequency

• Eliminates the need for a frequency board and frequency clips

• Fail-safe drives the servos to a preset position (usually full brakes) in the unlikely

event of signal loss

• No need to impound transmitters at events

• The DSM system is available for all popular module-based 3-channel transmitters

• 2.4GHz worldwide band allows international use

• Short 8.5" receiver antenna is easy to mount

• Telemetry-ready— optional modules allow real time monitoring of head temperature, rpm,

speed, battery voltage, lap times, etc.

• No maintenance or tuning required (always stays in tune)

• No need for crystals

• Up to 79 users can simultaneously operate DSM systems with no interference

• FCC, UKCC, ROAR, NORCCA and ETSI approved

Spectrum Modulation

The DSM system operates in the 2.4GHz band (that’s 2400MHz). This high frequency offers a signiﬁcant advantage as it’s well out of the range of model-generated radio interference (like motor and ESC noise). All the complex issues that now exist using 27 and 75MHz radios with model-generated interfering noise are eliminated with this system. The DSM system uses Direct Sequence Spread Spectrum modulation to generate a wide signal on a single frequency. The FCC requires that these systems be “smart”– incorporating collision avoidance such that when a system is turned on, it scans the

2.4GHz band and selects a channel that is not being used, then begins transmitting on that unused channel. 79 channels are available and the odds of one DSS spread spectrum system interfering with another are astronomically remote. The 2.4GHz spectrum has a capacity of 79 channels. In the unlikely event that the spectrum is full, the 80th system will not connect or cause any interference, going into hold scan until a channel is free.
