Receiver Connection and Installation

Electric Installation The antenna should be mounted up away from the vehicle and in an antenna tube if possible.

Binding Receiver to Transmitter

In order to operate, the receiver must be bound to the transmitter. Binding is the process of teaching the receiver the speciﬁc transmitter’s code called GUID (Globally Unique Identiﬁer). When a receiver is bound to a transmitter/model memory, the receiver will only respond to that speciﬁc transmitter/model memory.

Binding

Note: The SR3300T receiver utilizes the DSM protocol and features telemetry output.

1. With the receiver off, insert the bind plug into the BIND/RS port in the receiver.

2. Power the receiver through any port that is not a 3.3V Telemetry port. If an ESC is being used, power on the ESC with the ESC lead plugged in the throttle channel port. The amber LED will ﬂash continuously indicating that the receiver is in bind mode.

Warning: Do not power the SR3300T through the LAP, TEMP or RPM port. The receiver will be damaged!

3. With the steering wheel, throttle trigger and Aux channel (if applicable) in the desired preset failsafe positions, initiate the bind process with your Spektrum transmitter which will also store the failsafe positions. Please see the next section for more information about Failsafe.

4. The LED on the receiver should now be solid, indicating a successful bind has taken place.

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

Note:

The only time it is necessary to do a rebind is if different failsafe positions are desired e.g., servo travel has been reversed after the initial bind, or if the receiver is to be bound to a different model memory.

Gas installation

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.

Binding the Transmitter to the Handheld Telemetry Unit

In order for the receiver to communicate with the Spektrum Handheld unit (optional), the handheld unit must also be bound to the transmitter.

Note: When changing models it will be necessary to rebind the handheld unit to that model

due to ModelMatch.

Binding the Handheld Unit

1. Press and hold the button while turning on the handheld unit. The LED should ﬂash indicating the unit is in bind mode.

2. With the steering wheel, throttle trigger and Aux channel (if applicable) in the desired preset failsafe positions and the handheld unit in close proximity, initiate the bind process with the transmitter, which will also store failsafe positions. Refer to your Spektrum transmitter user guide.

3. When a successful bind is complete, the LED will go off on the handheld unit and the voltage reading will be displayed.

Installing the Telemetry Sensors in Your Vehicle

Note: The telemetry sensor ports are regulated at 3.3 volts and cannot be used to power a transponder.

If using a transponder it must be plugged in the battery or one of the channel ports to operate properly.

Press and hold the button while turning on the handheld unit to enter bind mode.

RPM/Speed Port

Signal and Receiver Battery Voltage

Signal strength and receiver battery voltage are built into the receiver’s telemetry and no further attachment of sensors is necessary. Signal strength and receiver battery voltage will be displayed when the transmitter and receiver are both turned on.

RPM/Speed Sensor (Nitro)

An optional infrared sensor is needed to record rpm values that can be converted by the telemetry compatible transmitter or handheld unit 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. It is necessary to place a reﬂective or light absorbing decal on the ﬂywheel to allow the sensor to record rpm.

RPM/Speed Sensor Installation (Nitro)

• Choose the correct nitro mount for your engine.

• 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 ywheel.

Depending on your ﬂywheel size, the sensor might have to be mounted in different orientations.

• If the ywheel is reective (bare metal), place a at 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. We recommend applying a small amount of CA glue around the edges of the decal to ensure strong adhesion. Be sure to only glue the edges and to not cover the top of the decal.

• Plug the sensor into the RPM port in the SR3300T receiver.

RPM/Speed Sensor (Electric)

In electric cars and trucks, the rpm sensor is mounted near the spur gear and gets rpm readings directly from that gear. A conversion in the transmitter can be programmed to give speed in mph or rpm. See the Telemetry Speed Unit section on rpm and speed for more details. Because of the diverse types of electric vehicles, it may be necessary to fabricate a mount from Lexan 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. A mount can be fabricated from Lexan and taped in place using servo tape then bent to allow installation in most applications.

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

• If the gear is non-reective, place a reective 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 the SR3300T receiver.

Temperature Sensor (Nitro)

An optional temperature sensor loop is needed that wraps around the head of the engine to monitor head temperature. This is useful in tuning engines and in preventing damaging over-lean 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 the SR3300T receiver. The Telemetry screen on the DX3S should now display the room temperature.

Temperature Sensor (Electric)

An optional Thermister-type temperature sensor is needed in the electric system that can be taped to the battery or motor to monitor real-time temperature. Transparent tape can be used to attach the sensor for temperatures up to approximately 250°F. High temperature tape is needed for temperatures exceeding 250°F.

Temperature Sensor Installation (Electric)

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

• Plug the temperature sensor into the port marked TEMP in the SR3300T receiver.

The Telemetry screen on the DX3S transmitter should now display room temperature.

Tips on Using 2.4GHz Systems

Your DSM equipped 2.4GHz system is intuitive to operate, functioning nearly identically to FM systems. Following are a few common questions from customers:

1. Q: Which do I turn on ﬁrst, the transmitter or the receiver? A: It doesn’t matter, although it is suggested to turn the transmitter on ﬁrst. If the receiver is turned

on ﬁrst, all channels will be driven to the failsafe position 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 turned on, the receiver scans the 2.4GHz band looking for the previously stored GUID. 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. Why? A: In order for the system to connect (after the receiver is bound), the receiver must receive a large

number of continuous (one after the other) uninterrupted perfect packets from the transmitter. This process is purposely critical of the environment ensuring that it’s safe to drive 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 (inside or around a pit trailer, metal transmitter case, the bed of a truck,

the top of a metal work bench, etc.) connection will take longer. In some cases connection will not occur as 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 up again will enable a connection to occur. This only happens during the initial connection. Once connected the system is locked, and should a loss of signal occur (failsafe), the system connects immediately (4ms) when signal is regained.

3. Q: I’ve heard that the DSM system is less tolerant of low voltage. Is this correct? A: The SR3300T has an operational voltage range of 3.2 to 9.6 volts. With most systems this is not a

problem as in fact most servos cease to operate at around 3.8 volts. When using multiple highcurrent draw servos with a single or inadequate battery/power source, heavy momentary loads can cause the voltage to dip below this 3.2-volt threshold causing the entire system (servos and receiver) to brown out. When the voltage drops below the low voltage threshold (3.2 volts), the receiver must reboot (go through the start-up process of scanning the band and ﬁnding the transmitter) and this can take several seconds.

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

bind is lost during use?

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 system fails to connect, more than likely the transmitter is near conductive material

(transmitter case, truck bed, etc.) and the reﬂected 2.4GHz energy is preventing the system from connecting. (See #2 above)
