Inadequate or intermittent power to the receiver that does not provide the necessary minimum voltage during operation is the number one cause of control failures with Spektrum systems. Some 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.

maIN sCrEEN rECOmmENdEd POwEr sysTEm

TEsT guIdElINEs

If you are using a questionable power system (e.g. small or old battery, ESC that may not have a BEC that will support the servo’s current draw), you should use a voltmeter to perform the following test.

Plug the voltmeter into an open channel port in the receiver. 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 shows up during shock and vibration, so this test verifies the battery construction is good.

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. Typical telemetry range is 100–200 feet and will vary depending on the operating environment. If range issues exist, you can optimize your installation by extending the receiver’s antenna as vertically as possible. Locating it as high in the vehicle as practical and also route the antenna away from any onboard electronics.

ExPONENTIal

With Exponential you can affect the response rate of the steering, throttle and/or brake.

Typically positive Exponential is used for steering, reducing steering sensitivity around neutral and making it easier to drive the car at high speeds in a straight line. But exponential still allows for the maximum turning radius.

The DX3R PRO’s Exponential function (Expo for short) allows independent Expo values in each direction of all three channels—steering, throttle and auxiliary. A graphic illustration displays the effect of exponential adjustment.

bINdINg

In order to operate you must bind the receiver to the transmitter. Binding is teaching the receiver to recognize the transmitter’s specific GUID code.

The DX3R Pro employs ModelMatch so the receiver stores the code assigned to the currently selected model in the transmitter. So when the receiver is bound to a transmitter/model memory, the receiver only responds to the stored transmitter/model memory. This prevents operating a model using the wrong model memory.

faIlsafE

Failsafe positions are also set during binding. In the unlikely event that the radio link is lost during use, the receiver will drive the servos to their preprogrammed failsafe positions (normally full brakes and straight steering). If the receiver is turned on prior to turning on the transmitter, the receiver will enter failsafe mode, driving the servos to their preset failsafe positions.

When the transmitter is turned on, normal control is resumed. Failsafe servo positions are set during binding (see binding a receiver below).


bINdINg a rECEIvEr

Note: The SR3100 operates in DSM2 mode only and is compatible with DSM2 transmitters.

1. With the receiver off, insert the bind plug into the Batt/

Bind port in the receiver.

2. Power up the receiver. If using an electronic speed controller, plug the lead into the throttle port and turn on the switch. If using a receiver pack, plug the battery lead into any open port noting the polarity. The LED on the receiver will begin flashing.

3. Turn on the transmitter and make sure the transmitter is in the model number you intend to use.

4. Press the rolling selector to access the List screen.

5. Rotate the roller to highlight the Bind screen and press the roller to access this screen.

6. Rotate the roller to highlight BIND.

7. With the steering wheel, throttle stick and Aux channel

(if applicable) in the desired preset failsafe positions, press the roller to initiate the bind process and to store the failsafe positions. BIND will flash for a few seconds then the transmitter will beep, indicating the process is complete. The LED on the receiver should now be solid, indicating a successful bind.

8. Remove the bind plug and store it in a convenient place.

Note: The only time you need to rebind is if you desire different failsafe positions or if binding the receiver to a different model memory.


Note: Some Spektrum receivers like the SR3001 use a bind button rather than a bind plug. The binding process is the same with this receiver. However, instead of inserting the plug before powering up the receiver, press and hold the bind button while powering up the receiver to enter bind mode.

framE raTE

For compatiblity with all types of servos, three frame rates are available.

5.5ms: Gives the fastest response rate; is only compatible with high-performance digital servos. DSM surface receivers output at 11ms and Marine receivers output at 22ms when 5.5ms is selected.

Note: when 5.5ms frame rate is selected only two channels (steering and throttle) are operational.

11ms: Offers good response rates and is compatible with most digital and analog servos (this is the default position). Works with both DSM and DSM2 surface receivers. Marine receivers output at 22ms when 11ms is selected.

16.5ms: This is the least responsive rate and is needed for older analog servos. Works with both DSM and DSM2 surface receivers. Marine receivers output at

22ms when 16.5ms is selected.

Note: You should always use the fastest response rate the servos can handle. This gives the lowest latency and fastest response. If the frame rate is incompatible with the servo, the servo will move erratically or in some cases not at all. If this occurs, change the frame rate to the next highest value.

Telemetry Sensor Settings

The DX3R PRO allows you to modify the settings for the Speed, Temp, and Batt sensor.

Tele: Speed

Unit: Select MPH or KM/H display units.

Roll Out: The Roll Out function is the internal calculator that can convert rpm data to mph or km/h. When the

Roll Out value is set to 1.0, the default setting, the value displayed on the main screen and stored in maximum speed is true rpm of the shaft gear or flywheel that the rpm sensor is hooked up to. In order to program the unit to display speed in mph, a conversion factor is needed. Following are two methods of determining the conversion factor.

Method A

• Mark the clutch bell that the sensor is reading from with a small reference mark. A marker works well.

• Set the car next to a ruler and at 0” then roll the car forward by hand, counting each revolution of the reference mark. At exactly 10 revolutions stop the car.

• Measure the exact distance the car traveled in ten revolutions and divide this distance by 10 (e.g.,

12.0” divided by 10 = 1.20”).


• Adjust the Roll Out value until 1.20 appears on the screen. Now all the rpm related functions will display in mph or km/h.

Method B

For this method you either need to know the internal gear ratio (normally provided in the vehicle’s manual) or calculate the ratio via the number of teeth on the gears. It is also necessary to calculate the circumference

(distance around) of the tire. Once the internal ratio is known, and the circumference in inches determined, divide the circumference by the internal ratio and use this value as the conversion.

To calculate circumference, multiply 3.14 x the tire’s diameter in inches.

To calculate internal gear ratio, divide the larger gear by the small gear. With multiple gear transmissions, multiply each of the larger to smaller gear reduction ratios to arrive at the final ratio.

Note: The Telemetry screen displays the maximum recorded speed from the point the receiver was turned on. To reset the maximum recorded speed, turn off the receiver, then back on.

Tele: Temp

Unit: Display Temperature Unit in degrees Fahrenheit or Celsius.

Alert: The Temperature Alert allows you to preset an alert warning when you reach a specified temperature.

Note: The Telemetry screen displays the maximum achieved temperature from the point the receiver was turned on. To reset the maximum temperature, turn off the receiver, then back on.

Tele: Batt

Note: The voltage displayed is the receiver voltage. This is especially useful for nitro cars in alerting you to change your receiver pack before your vehicle goes into failsafe due to low battery pack voltage.

Alert: The Battery Alert setting allows you to preset a low voltage warning. When the battery voltage in your receiver drops below the preset voltage, the transmitter will alert you by beeping. Typical recommended preset value is 1.1-volt per cell.

However, when using high-current draw servos, reduce that value to .9-volt per cell.

Recommended voltage settings:

• 5-cell 6.0-volt pack = 5.5 volts

• 4-cell 4.8-volt pack = 4.4 volts

Receiver battery voltage is built into the telemetry compatible receiver and no further attachment of sensors is necessary.

Note: The receiver battery must be above 3.5 volts for proper telemetry operation.

rPm/sPEEd sENsOr (NITrO) (sPm1452)

An infrared sensor is available to record rpm values that the transmitter unit can convert to actual speed in mph or km/h.

The sensor emits an infrared light and a receptor records the reflection vs. the absorption of light. You need to place a reflective or light absorbing decal (provided) on the flywheel to allow the sensor to record rpm. Mounting hardware is available for easy installation.

RPM/Speed Sensor Installation (Nitro)

• Choose the correct nitro mount for your engine.

Two mounts are available : one for .12–.15 engines

(SPM1502) and one for .21–.26 engines (SPM1501).

EN


EN

• Using the 2mm screws, attach the sensor to the mount as shown.

• Install the mount under the engine screw and adjust the sensor so it is 1/8” from the flywheel. Depending on your flywheel size, the sensor might have to be mounted in different orientations.

• If the flywheel is reflective (bare metal), place a flat black decal on the flywheel so it passes between the sensor and the flywheel when rotated. If the flywheel is non-reflective, place a reflective decal on the flywheel so that it passes between the sensor and the flywheel when rotated.

19

Hint: We recommend applying a small amount of CA glue around the edges of the decal to ensure strong adhesion. Only glue the edges and do not cover the top of the decal.

• Plug the sensor into the RPM port in your receiver.

rPm/sPEEd sENsOr (ElECTrIC) (sPm1503)

In electric cars and trucks, the rpm sensor is mounted near the spur gear and gets rpm readings directly from that gear. You can program a conversion in the transmitter to give speed in mph or rpm. See the Telemetry Speed

Unit section on rpm and speed for more details. A mount is available that allows the rpm sensor to be mounted in many applications. Because of the diverse types of electric vehicles, you may need to fabricate a mount from polycarbonate material for some types of vehicles.

RPM/Speed Sensor Installation (Electric)

• Determine the best method to mount the sensor near the spur gear. The face of the sensor must face the side of the gear. You can tape a mount in place using servo tape then bend it to allow installation in most applications.

• Mount the rpm sensor so the sensor is 1/8” from the side of the gear.

• If the gear is non-reflective, place a reflective decal on the gear so it passes between the sensor and the flywheel when rotated. If the gear is reflective, place a flat black decal on the gear so it passes between the sensor and the gear when rotated.

• Plug the sensor into the RPM port in your receiver.

TEmPEraTurE sENsOr (NITrO) (sPm1450)

A temperature sensor loop is available that wraps around the head of the engine to monitor head temperature. This is useful in tuning engines and in preventing damaging overlean runs.

Temperature Sensor Installation (Nitro)

• Install the loop as shown around the cylinder of the engine. It is best to place the sensor near the point


at which the head meets the cylinder to get the most accurate, consistent readings.

• Plug the temperature sensor into the port marked

TEMP in your receiver. The Telemetry screen on the

DX3R PRO should now display the room temperature.

TEmPEraTurE sENsOr (ElECTrIC) (sPm1451)

A Thermister-type temperature sensor is available that can be taped to the battery or motor to monitor real-time temperature. You can use transparent tape to attach the sensor for temperatures up to approximately 250°F high. High-temperature tape is needed for temperatures exceeding 250°F.

Temperature Sensor Installation (Electric)

• Tape the temperature sensor to the area you wish to monitor (normally the batteries or motor).

• Plug the temperature sensor into the port marked

TEMP in your receiver. The Telemetry screen on the DX3R PRO transmitter will now display room temperature.

laP COuNTEr/TImEr (sPm1453)

The lap counter displays the lap time. In order to use the lap timer, an optional lap trigger, onboard telemetry module

(SPM1325) and SR3001 receiver (SPM1205) are required for the lap counter. The lap counter/timer system utilizes an infrared sensor in the car and the lap trigger projects an infrared light across the track that triggers the sensor when the car passes. A Lexan mount is provided to allow easy mounting of the lap counting sensor in your vehicle.

Note: The lap sensor must be mounted in visible sight of the lap trigger. Normally this means just inside the side window. If the windows are painted, it will be necessary to cut a small hole in the body to allow the IR light to trigger the sensor.

Lap Counter/Timer Installation

• Servo tape the lap sensor to the Lexan mount.

• Determine the mounting position that will place the sensor behind the side window.

• Cut and/or bend the Lexan mount to position the sensor in the appropriate position and servo tape the mount in place.

• Plug the lap sensor into the L (lap) port in the telemetry module.

laP TrIggEr (sPm1330)

The Lap Trigger is placed next to the track and projects an infrared beam of light across the track that triggers the infrared sensor in the car each time it passes. The receiver records each lap time and sends that information to the transmitter where it is displayed. A programmed delay of 2 seconds prevents double lap counts.

Installing the Lap Trigger Battery

Use 3/32” and 5/64” hex wrenches to unscrew the case and install the 9-volt battery as shown. Reinstall the case, being careful not to over-tighten the screws.

Note: A typical 9-volt battery will power the lap timer for 9 hours.

Mounting the Lap Trigger

Mont the lap trigger 8 inches to 36 inches (20 to 91cm) above the racing surface facing outward from the track.

Facing the trigger outward keeps the IR beam from crossing the track in more than one lane preventing unwanted false triggering. Hook and loop strips make mounting easy.

Only one lap trigger is necessary at each track, as a single infrared beam will trigger the lap timer in all cars.

gENEral NOTEs

As the user of this product, you are solely responsible for operating it in a manner that does not endanger yourself and others or result in damage to the product or the property of others.

Carefully follow the directions and warnings for this and any optional support equipment (chargers, rechargeable battery packs, etc.) that you use.

Safety Points to Obey for Modelers

• Ensure your batteries (both transmitter and receiver) have been properly charged for your model.

• Keep track of the time the system is turned on so you will know how long you can safely operate the transmitter.

• Check all servos and their connections prior to each run.

• Do not operate your model near spectators, parking areas or any other area that could result in injury to people or damage of property.

• Do not operate your model during adverse weather conditions. Poor visibility can cause disorientation and loss of control of your model.

• Do not point the transmitter antenna directly toward the model. The radiation pattern from the tip of the antenna is inherently low.

• Do not take chances. If at any time during the operation of your model you observe any erratic or abnormal operation, immediately stop operation of your model until the cause of the problem has been ascertained and corrected. Safety can never be taken lightly.

Problem

• The system will not connect

• The receiver goes into failsafe mode a short distance away from the transmitter

• Receiver quits responding during operation

DX3R PRO Troubleshooting Guide

Possible Cause

• Your transmitter and receiver are too close together. They should be 1 to 4 feet apart.

• You are around metal objects.

• Your transmitter was accidentally put into bind mode and is not bound to your receiver anymore.

• Check the receiver antenna to be sure it is not cut or damaged.

Solution

• Move transmitter 1 to 4 feet from receiver.

• Move to an area with less metal.

• Rebind your transmitter and receiver.

• Inadequate battery voltage

• Loose or damaged wires or connections between battery and receiver

• Replace SR3100 antenna (SPM9005) or contact

Horizon Product Support

• Make sure your antenna is in an antenna tube and up in the air as high as possible

• Charge batteries. Spektrum receivers require at least 3.5V to operate. An inadequate power supply can allow voltage to momentarily drop below 3.5V and cause the receiver to brown out and reconnect.

• Check the wires and connection between battery and receiver. Repair or replace wires and/or connectors
