Spektrum SPMSR3300T - Manual

SR3300T Instruction Manual
Spektrum’s SR3300T 3-channel DSM ® receiver features integrated telemetry that is compatible using
Spektrum’s handheld telemetry unit (not included) or telemetry can be displayed on screen using the
Spektrum telemetry-compatible transmitters. Telemetry features include voltage, temperature, rpm and laps
(handheld only). The SR3300T is compatible with all Spektrum surface transmitters and operates in DSM
mode.
Note: The SR3300T receiver does not include the telemetry sensors or rpm sensor mount hardware.

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.

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 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. 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.
