FUTABA RECEIVER R3104SB T-FHSS

A small four-channel telemetry receiver for Futaba's T-FHSS Air-2.4 GHz transmission system with a pair of full-band diversion antennas. It is designed for use in models of all categories; with its compact size, light weight and longitudinal-axis connectors, it is also suitable for small models. The R3104SB provides 4 classic PWM channel outputs and an S.BUS2 port for bidirectional communication to connect S.BUS2 servos and telemetry sensors. It supports the "Model ID" function. The receiver's operating states are indicated by an LED.

Transmission system:

Futaba T-FHSS Air-2.4GHz for flying models. Not compatible with the T-FHSS Surface 2.4GHz transmission system used by Futaba RC kits for RC cars, other ground vehicles and boats.

Power supply:

4.8-7.4 V (nominal voltage) - that is, for example, 4-6 NiMH, 2S LiPo, LiFe, Li-ion batteries, BEC power stabilizers within the specified voltage range.

Antenna:

The receiver is equipped with a pair of diversion antennas to maximize signal reception regardless of the relative positions of the model and transmitter. They must be mounted on the model with a mutual orientation of 90°.

Receiver outputs:

The receiver allows connection of standard Futaba connectors (with protrusion) and UNI connectors (=JR/Graupner, Hitec) without side protrusion.

• Channel outputs (PWM): The R3104SB offers 4 classic PWM channel outputs that can be used simultaneously with the S.BUS2 serial bus.
• S.BUS2: The S.BUS2 socket allows the connection of S.BUS2 servos, gyros and other compatible devices, as well as the connection of Futaba telemetry sensors, whose data can be displayed on the transmitter.

Telemetry:

• The R3104SB transmits receiver power voltage data to the transmitter without connecting any sensors.
• The R3104SB allows the use of all Futaba telemetry sensors and other sensors compatible with the S.BUS2 bidirectional bus system.

The receiver kit includes: the R3104SB receiver, instruction manual.

What is S.BUS2/S.BUS

• S.BUS - Futaba's serial bus with unidirectional communication that allows control of servos, controllers, switches, gyros and other compatible RC devices connected to a single output port of the S.BUS receiver.
• S.BUS2 - Futaba's serial bus for bi-directional communication allowing (as S.BUS) control of servos, controllers, switches, gyroscopes and other compatible RC devices connected to the single output/input port of the S.BUS2 receiver. In addition, it allows the connection of telemetry sensors and the transmission of data from them through the receiver for display on the transmitter; from some servos, the S.BUS2 can transmit operating current, temperature or servo output lever angle information to the transmitter.

Unlike classic RC kits, the S.BUS(2) system uses serial data communication to send control signals from the receiver to a servo, gyroscope or other device. This data includes commands such as "move channel 3 servo by 15 degrees, move channel 5 servo by 30 degrees" for many devices. S.BUS(2) devices only execute commands belonging to their own set channel. For this reason, it is possible to connect several servos to the same signal cable, setting and controlling them individually as needed. The servo's identification code (ID) is used for this purpose. The ID can be found on a sticker on the servo.

The S.BUS2 servo can be connected to the receiver's S.BUS2 and S.BUS ports. Its function is determined by setting the channel in the servo's memory (this is done using the programming interface of the Futaba transmitter, the SBC-1 programmer or the CIU-3 USB interface with the S-Link PC program - for some servos, the channel can only be set using the transmitter).

An S.BUS or S.BUS2 servo connected to the channel output of a classic receiver (PWM) works like a classic servo. Its movement is given by the signal in the channel of the receiver to which it is connected. The settings of the programmable servo functions remain in effect.
