Futaba R2000SBM S-FHSS / FHSS 8k 2.8g receiver

Miniature and very light receiver Futaba transmission system S-FHSS 2.4GHz without telemetry with a pair of diversity antennas with full range. It is designed primarily for use in FPV drones and other models using control units communicating via S.BUS; thanks to its miniature dimensions and very low weight, it is also suitable for small aircraft models with S.BUS / S.BUS2 servos. The R2000SBM provides one serial S.BUS output. The operating states of the receiver are indicated by an LED indicator.

Transmission system

Futaba S-FHSS 2.4GHz for flying models (for Futaba S-FHSS transmitters and RF module TN-FH).

Power supply

4.8-7.4 V (nominal voltage) - ie eg 4-6 cells NiMH, 2S LiPo, LiFe, Li-ion batteries, BEC power stabilizers in the given voltage range.

Antenna

The receiver is equipped with a pair of diversity antennas in order to maximize signal reception regardless of the relative position of the model and the transmitter. These must be fastened in the model with a mutual orientation of 90 °.

Receiver outputs

The receiver is equipped with a three-core S.BUS output cable with a Futaba servo connector. The S.BUS output has a maximum of 8 channels.

Telemetry

The R2000SBM does not allow telemetry transmission, but allows the received signal strength (RSSI) data to be transmitted to the drone control unit.

The receiver set includes: R2000SBM receiver, operating instructions.

What Is S.BUS2 / S.BUS

• S.BUS - Futaba serial bus with one-way communication enabling control of servos, controllers, switches, gyroscopes and other compatible RC devices connected to a single output port of the S.BUS receiver.
• S.BUS2 - Futaba serial bus for bidirectional communication enabling (as S.BUS) control of servos, controllers, switches, gyroscopes and other compatible RC devices connected to a 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 via a receiver for display on the transmitter; from some S.BUS2 servos can transmit information about the operating current, temperature or angle of the servo output lever to the transmitter.

Unlike conventional RC S.BUS (2) kits, the system uses serial data communication to transmit control signals from the receiver to a servo, gyro or other device. This data contains commands such as "move servo channel 3 to 15 degrees, move servo channel 5 to 30 degrees" for multiple devices. S.BUS (2) devices only execute commands corresponding to their own set channel. For this reason, it is possible to connect several servos to the same signal cable, while setting and controlling them individually as needed. The servo identification code (ID) is used for this. You can find the ID on the sticker on the servo box.

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

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