Introduction

DX2.0 Quick Start Setup

Thank you for purchasing Spektrum’s DX2.0 radio system. The DX2.0 is designed to provide RC racers with a bulletproof 2.4GHz spread spectrum radio link. With the DX2.0 DSM system you’ll no longer have to wait for a frequency clip, worry about radio interference from noisy motors or ESCs or be concerned that someone may turn on a radio on your channel causing interference. In addition, the DX2.0’s programming is user-friendly and offers the most important features and functions that racers demand. It’s important that you carefully read this manual before attempting to operate your DX2.0 system.

For those who would like to get out to the track quickly with just the basic radio setup, please refer to the Quick Start section that follows.

Included in this manual are in-depth instructions detailing all the steps and procedures needed to correctly program each of the DX2.0’s features. Quick Start covers the basic programming information necessary to get you to the track fast. Later, when you want to learn more about the speciﬁc features of the DX2.0, refer to the appropriate page(s) in this manual for more detailed programming information.

Binding

It’s necessary to program the receiver to a speciﬁc transmitter so that the receiver will only recognize that transmitter, ignoring signals from any other sources. If the receiver is not bound to a transmitter, the system will not operate. Also, during the binding process, the servo failsafe positions are set.

1. Make sure the transmitter and receiver are turned off.

2. With the receiver off, insert the bind plug into the BIND port on the receiver.

3. Power the receiver through any port. The green LED will ﬂash continuously, indicating the receiver is in bind mode.

4. Hold down on the SCROLL and CHANNEL buttons while turning on the transmitter. To enter System Mode, press the SCROLL button until “BND” appears on the screen.

5. With the steering wheel and the throttle trigger in their desired failsafe positions, press the INCREASE and DECREASE buttons at the same time to enter bind mode. “BND” will ﬂash when in bind mode.

6. After several seconds the LED on the receiver will quit ﬂashing and remain solid, indicating that the binding process was successful. Once binding is complete, the system will automatically connect.

7. Once the bind process is complete and before power is cycled on the receiver, remove the bind plug from the receiver and store it in a convenient place. Failure to remove the bind plug will result in the receiver going back into bind mode.

DX2.0 with Digital Spectrum Modulation

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. 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.

During the ﬁrst installation, the receiver(s) must be bound to the transmitter. Binding is necessary to program the receiver(s) to distinguish its corresponding transmitter from others. Also failsafe positions are transferred from the transmitter to the receiver during binding. (See binding below for more details.)

It is necessary to bind the receiver to the transmitter during the ﬁrst installation, and is recommended when the receiver is moved from one vehicle to another. Receivers can be re-bound to the same transmitter or to other transmitters an inﬁnite number of times. Also multiple receivers can be bound to a single transmitter, which is common when using one transmitter to operate several models.

Only bound receivers and transmitters can connect. During power-up, the transmitter scans for a free channel while the receiver scans for its bound transmitter. When control is achieved, the LED on the receiver remains on continuously.

b D

At 3.6 inches in length, the receiver antenna is signiﬁcantly shorter than conventional antennas. Like all antennas, it’s important to mount the antenna vertically. In most cases the antenna can be mounted inside the body with no loss of range. Mount the receiver antenna as recommended by the manufacturer of the vehicle, however, it may be necessary to trim the plastic antenna tube (included with your vehicle).

In the unlikely event that the link is lost during use, the receiver will drive the servos to their failsafe 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 failsafe mode, driving the servos to their preset failsafe position. When the transmitter is turned on, normal control is resumed.

To Bind the Receiver to the Transmitter

1. Make sure the transmitter and receiver are turned off.

2. With the receiver off, insert the bind plug into the BIND port on the receiver.

3. Power the receiver through any port. The green LED will ﬂash continuously, indicating the receiver is in bind mode.

Receiver Power System Requirements

Power System Test Guidelines

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:

•Receiverbatterypack(numberofcells,batteryconstructionquality,connectorandstate

of charge)

•TheESC’scapabilitytodelivercurrenttothereceiverandservosinelectricvehicles

•Theswitchharness,batteryleads,servoleads,regulatorsetc.

All Spektrum receivers have a minimum operational voltage of 3.5 volts. If the voltage drops below 3.5 volts, the system will cease control until power is regained.

If a questionable power system is being used (e.g. small or old battery, ESC that may not have a BEC that will support the servo’s current draw, etc.), it is recommended that a voltmeter be used to perform the following test.

Plug the voltmeter into an open channel port in the receiver and with the system on, load the servos (apply pressure with your hand) while monitoring the voltage at the receiver. The voltage should remain above 4.8 volts even when all servos are loaded. For gas vehicles, tap and twist the receiver battery pack while watching the voltmeter. Some battery packs have poorly welded tabs that give only intermittent power. Such a defect will show up during shock and vibration, so this test will verify that the battery construction is good.

While your DSM equipped 2.4GHz system is intuitive to operate, functioning nearly identically to 27 and 75MHz systems, following are a few common questions from customers.

1. Q: Which do I turn on ﬁrst, the transmitter or the receiver?

Typical Range

Your system’s range can vary greatly due to your installation and the environment. In most cases you should be able to have full control of your vehicle to the limits of sight (about 300 ft with a 1/10-scale car). If range issues exist your installation can be optimized by extending the receiver’s antenna as vertically as possible locating it as high in the vehicle as practical and also by routing the antenna away from any onboard electronics.

A: If the receiver is turned on ﬁrst—all servos will be driven to their preset failsafe positions set during binding. When the transmitter is then turned on, the transmitter scans the 2.4GHz band and acquires an open channel. Then the receiver that was previously bound to the transmitter scans the band and ﬁnds the GUID (Globally Unique Identiﬁer code) stored during binding. The system then connects and operates normally.

If the transmitter is turned on ﬁrst—the transmitter scans the 2.4GHz band and acquires an open channel. When the receiver is then turned on for a short period (the time it takes to connect) all servos are driven to their preset failsafe positions. The receiver scans the 2.4GHz band looking for the previously stored GUID and when it locates the speciﬁc GUID code and conﬁrms uncorrupted repeatable packet information, the system connects and normal operation takes place. Typically this takes 2 to 6 seconds.

2. Q: Sometimes the system takes longer to connect and sometimes it doesn’t connect at all.

A: In order for the system to connect (after the receiver is bound) the receiver must receive a large number of consecutive uninterrupted perfect packets from the transmitter. This process is purposely critical of the environment, ensuring that it’s safe to operate when the system does connect. If the transmitter is too close to the receiver (less than 4 feet) or if the transmitter is located near metal objects (metal Tx case, the bed of a truck, the top of a metal workbench, etc.) connection will take longer and in some cases connection will not occur. The system is receiving reﬂected 2.4GHz energy from itself and is interpreting this as unfriendly noise. Moving the system away from metal objects or moving the transmitter away from the receiver and powering the system again will cause a connection to occur. This only happens during the initial connection. Once connected, the system is locked in and, should a loss of signal occur (failsafe), the system connects immediately (4ms) when the signal is regained.

3. Q: I’ve heard that the DSM system is less tolerant of low voltage. Is that correct?

Control

RC Safety Precautions

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.

4. Q: Sometimes my receiver loses its bind and won’t connect, requiring rebinding. What happens if the bind is lost in ﬂight?

A: The receiver will never lose its bind unless it’s instructed to. It’s important to understand that during the binding process the receiver not only learns the GUID (code) of the transmitter, but the transmitter learns and stores the type of receiver that it’s bound to. If the transmitter is placed into bind mode, the transmitter looks for the binding protocol signal from a receiver. If no signal is present, the transmitter no longer has the correct information to connect to a speciﬁc receiver and in essence the transmitter has been “unbound” from the receiver.

For safe and reliable performance of your RC model, please carefully read and follow these guidelines:

1. Radio control models are not toys. They are capable of inﬂicting serious injury to people and property. Use caution at all times when operating your model.

2. You are responsible for the safe operation of your RC model. You must properly install, test and operate your model with a clear sense of that responsibility. Do not take risks that might endanger yourself or others.

3. Running an RC car in the streets is very dangerous to both drivers and models. Avoid running your model in areas occupied by full-size automobiles. To locate areas where you can safely operate your model, you should contact your local hobby shop for RC tracks or clubs in your area.

4. If at any time while operating your RC model you sense abnormal model functioning, end your operation immediately. Do not operate your model again until you are certain the problem has been corrected.

CAUTION: Control of your model is impossible without sufﬁcient voltage for the

transmitter and receiver. A weak transmitter battery will decrease your range of operation and a weak receiver battery will slow servo movement and decrease your range of operation. Check your receiver pack voltage often to avoid losing control of your model.

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. This feature is very useful either to maximize servo travel or to reduce servo over-travel to eliminate servo binding (servo moves further than control mechanism allows), without the need for mechanical linkage adjustment. The screens below are accessed by turning the wheel to the desired direction to be adjusted (left or right), by moving the trigger to the forward or backward (brake) position, or by moving the Grip Lever A to the forward or back position.

Sub-Trim

(Function Mode)

The Sub-Trim function of the DX2.0 is an electronic trimming feature that allows the neutral position of the servo on either the steering or throttle channel to be moved, while allowing the electronic trim lever for that channel to remain in the center position. This feature is very useful, as it allows the servo arm/wheel position to be moved to help with control linkage installation, eliminating the need to make mechanical linkage adjustments. Although the Sub-Trim function is a very useful feature, it is suggested that only small amounts of subtrim be used so that no unwanted, non-equal servo travel is created. It is suggested that less than 30 points of Sub-Trim be used during adjustment. If more than 30 points of Sub-Trim are required, it is suggested that a mechanical linkage adjustment be performed.

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.

Accessing the Direct Trim Mode

(Function Mode)

The Direct Trim Mode function of the DX2.0 is accessible through the use of the electronic throttle or steering trim levers, as well as the two electronic grip levers (A&B) located on the upper portion of the grip handle. This function allows for quick trim adjustment of these controls, without the need to access these functions through the four keypad control keys.

To access the Direct Trim Mode function, turn on the transmitter power switch. Next, move the desired trim lever to be adjusted. The appropriate screen for the selected trim lever will be displayed. To adjust, simply move the trim lever in the desired direction until the correct amount of trim is achieved. Once the desired trim is achieved, the screen will return to the Normal display screen after approximately two seconds from the last trim input. If the INCREASE or DECREASE key is pressed any time during the two seconds, the system will return to the previous screen in use.

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. (For example: If trim value is set at 30 and endpoint values at 15, steering trim will override/alter the endpoint value.)

Throttle Trim (THC)

The DX2.0’s electronic Throttle Trim lever, located to the left of the steering wheel, allows the center position of the servo to be manipulated in either direction to achieve precise centering of the throttle trigger neutral position. Throttle Endpoint adjustment values (page 20) remain completely independent from the throttle trim, unless the trim value exceeds the selected endpoint values. (For example: If the trim value is set at 40 and the endpoint values at 30, Throttle Trim will override/alter the endpoint value.)

Each click will provide 0.3° of trim to the center of the steering servo with a maximum of 12° allowed.

Note: Each click will not always result in a change of the value displayed.

To adjust the steering trim servo position, move the electronic Steering Trim lever either to the left (+) or the right (-). As soon as the trim is moved, the STC Steering Trim screen will appear and will continue to be displayed unless the trim lever is untouched for a period of two seconds. To reset the trim value to 0, press the INCREASE and DECREASE keys at the same time while the STC screen is displayed.

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. Please note that since the Dual Rate value shown in the STG screen is the percentage of the endpoint value established in the steering EPA function, the value will not always increase or decrease each time the Grip Lever B is moved.

Brake Endpoint Adjustment BRK

The Brake Endpoint Adjustment, located at Grip Lever A, allows the maximum servo travel on the braking side of the throttle trigger to be increased or decreased from 100% to 0% (off). This function is very useful in race conditions as it allows the racer to custom tailor the “panic” brake value to maximize the car’s braking power for the current track conditions. Please note that since the brake endpoint value shown in the BRK screen is a percentage of the total braking value established in the Endpoint Adjustment function (page 20), the value will not always increase or decrease each time the Grip Lever A is moved. To adjust the brake endpoint value, move the electronic Grip Lever A either left (–) or right (+). As soon as the grip lever is moved, the BRK Endpoint Adjustment screen will appear and will continue to be displayed unless the Grip Lever A is untouched for a period of two seconds.

If the Emergency Steering button function (page 17) is active, pressing Grip Button C will restore the steering dual rate to 100% until the button is released.

To adjust the Steering Dual Rate value, move the electronic Grip Lever B either left (-) or right (+). As soon as the trim is moved, the STG Steering Dual Rate screen will appear and will continue to be displayed unless the Grip Lever B is untouched for a period of two seconds. To reset the trim value to the factory preset setting of 70%, press the INCREASE and DECREASE keys at the same time while the STG screen is displayed.
