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.
Benefits • 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.
DSM Digital Spread 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.
Installation Instructions Installing the Transmitter Module During first installation, the receiver(s) must be bound to the transmitter module. Binding is necessary to program the receiver(s) to distinguish its corresponding transmitter from others. Also fail-safe positions are transferred from the transmitter to the receiver during binding. See binding below for more details. 1. Make sure that the transmitter is switched off. 2. Remove the current RF module from the transmitter. 3.
Installing the Transmitter Module (continued) 4. Rotate and angle the antenna on the module to vertical. 5. If the transmitter is PPM and PCM compatible, make sure the transmitter is programmed to PPM modulation mode. If necessary, see the instructions included with your radio system for details. Note: When using the Futaba 3PK, it’s necessary to use the standard PPM mode and not the HRS mode.
Installing the Receiver 1. Using doublesided foam tape, mount the receiver in the position recommended in your vehicle’s instructions. 2. At 8.5 inches in length, the receiver antenna is significantly shorter than conventional antennas. The receiver has provisions that allow the antenna to exit the top of the receiver or at the end of the receiver. To switch antenna positions, it's necessary to open the case to change the antenna exit position.
Installing the Receiver (continued) Note: If desired, the antenna can be shortened (cut) to exactly 3.6" with negligible loss of range and in some applications the short 3.6" length will make installation easier. 3. Connect the servo and ESC leads per the chart below. The connections are compatible with Airtronics Z, JR®, Futaba, Hitec, and KO servos.
Channel Assignments Receiver Channel Usage Port 1 – Battery and telemetry options Port 2 – CH1 Steering Port 3 – CH2 Throttle Port 4 – CH3 Auxiliary channel or personal transponder Note: Align the servo leads so the black wire is towards the outside edge of the receiver case.
Binding Binding Process It’s necessary to program the receiver to a specific module so that the receiver will only recognize that module, ignoring signals from any other sources. If the receiver is not bound to a module, the system will not operate. Also during the binding process the servo fail-safe positions are set. It is only necessary to bind the receiver to the module during first installation and is recommended when the receiver is moved from one vehicle to another.
Binding Process (continued) 5. With the transmitter off, place the transmitter sticks and auxiliary channels in their desired fail-safe positions, normally brake and straight ahead steering. 6. Press and hold the bind button on the transmitter module. 7. Turn on the transmitter while holding the bind button. 8. Release the bind button after the green LED flashes.
Loss of Link / Fail Safe In the unlikely event that the link is lost during use, the receiver will drive the servos to their fail-safe positions that were preset during the binding process. If the receiver is turned on prior to turning on the transmitter, the receiver will enter the fail-safe mode driving the servos to their preset fail-safe position. When the transmitter is turned on, normal control is resumed. Note: The fail-safe positions can be checked by turning the power off on the transmitter.
