Binding 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 Sequencing Spread Spectrum modulation to generate a wide signal on a single frequency.
Receiver Power System Requirements Inadequate or intermittent power to the receiver that is unable to provide the necessary minimum voltage during operation is the number one cause of control failures with Spektrum systems. Some of the power system components that affect the ability to properly deliver adequate power include: System Features • DSM 2.
3. Q: I’ve heard that the DSM system is less tolerant of low voltage. Is that correct? A: All DSM receivers have an operational voltage range of 3.5 to 9.6 volts. With most systems this is not a problem as most servos cease to operate at around 3.8 volts. When using multiple high-current draw servos with a single or inadequate battery/ power source, heavy momentary loads can cause the voltage to dip below this 3.5-volt threshold thus causing the entire system (servos and receiver) to brown out.
Receiver Compatibility The DX2.0 features DSM technology and is compatible with Spektrum DSM and DSM2 surface receivers and the marine receiver. Charging Jack Compatible Spektrum Receivers The DX2.0 is compatible with the following receivers. Located on the left-hand side of the transmitter is the charging jack, which accepts only JR or Spektrum style wall chargers. Please do not attempt to use any other brand of wall charger as it may be reverse polarity and can cause damage to your system.
Display Screens Normal Display Screen When the power switch is turned on, the LCD screen will read as shown below. This screen is referred to as the Normal Display. Note: If any of the electronic trim buttons are moved while in this screen, the screen will automatically change to display the trim in use. This is called the Direct Trim Mode. For more information on the feature, please see page 5 of this manual.
Model Select (System Mode) The DX2.0 has memory for two models. This feature allows for two different models to be operated with the same transmitter (additional receivers and servos must be purchased separately) or one model with two different race setups. -- I (System Mode) Model Select Function The DX2.0 allows a three-character name to be input for each of the two (2) models available. The current model, with name, will then be displayed in the Normal display screen.
Data Reset (System Mode) The Data Reset function allows you to reset all the programming in the selected model (1 or 2) to the factory default settings. Before using the Data Reset function, it’s important to enter the Model Select function and check to make sure the current model number indicated (1 or 2) is the model to which you want to reset to the factory default settings. The Model Select function is described in detail on page 16.
Endpoint Adjustment (Function Mode) The Endpoint Adjustment feature of the DX2.0 allows the maximum travel of both the steering and throttle servos to be increased or decreased in each direction to achieve the exact servo movement needed. The Endpoint Adjustment range is from 0% to 125% and is factory set to 100% for both channels. The value displayed on the screen depends on the current position of the steering wheel, trigger, or trim lever to be adjusted.
Servo Reversing (Function Mode) The Servo Reversing feature of the DX2.0 is a very convenient feature when setting up a new model. The purpose of the Servo Reversing function is to change the direction of the servo rotation in relation to the wheel/trigger movement. The Servo Reversing function is available for the steering and throttle of the DX2.0.
Steering Trim (STC) The DX2.0 electronic Steering Trim lever, located just above the steering wheel, allows the center position of the servo to be manipulated in either direction to achieve precise centering of the steering assembly. Steering Travel Endpoint Adjustment values (page 20) remain completely independent from the steering trim, unless the trim value exceeds the selected endpoint values.
Grip Lever B: Steering Dual Rate Trim Adjustment STG The Steering Dual Rate Trim Adjustment, located at Grip Lever B, allows the dual rate value (maximum servo travel) to be increased or decreased within a range from 100% through 20% of the total endpoint value established in the steering EPA function. This function is very useful in race conditions as it allows you to custom tailor the steering radius and sensitivity for the current track conditions.
