Futaba R314SB T-FHSS 2.4GHz System S.BUS2, 4-Channel Receiver for Model Car
Introduction
Thank you for purchasing the R314SB receiver. The R314SB is designed for use with the Futaba T-FHSS system transmitter. It features the newly developed bidirectional communication system "T-FHSS".
Key Features
- Telemetry System: Allows display of running status on the transmitter. Telemetry data can be accessed by connecting optional telemetry sensors to the S.BUS2 connector.
- Mode Selection: Supports "Normal mode" for any type of servos or peripherals, and "High Speed mode" for digital servos (including BLS series) and most peripheral equipment like brushless ESCs. Please refer to the transmitter's manual for optimal use.
Compatibility
The R314SB is compatible with T-FHSS system transmitters. It does NOT work with current Futaba S-FHSS/FHSS/FASST-est/FASST systems.
Receiver Overview
The receiver unit features an LED indicator and a link switch.
Operating Precautions
Once the R314SB detects either the T-FHSS normal mode or T-FHSS high speed mode, the detected mode is locked as long as the power is ON. To change the mode, cycle the power.
Link Procedure
Each transmitter has a unique ID code. To start operation, the receiver must be linked with the transmitter's ID. Once linked, the ID is stored, and no further linking is needed unless pairing with a different transmitter.
- Place the transmitter and receiver close to each other, within 0.5 meters (approx. 1.6 feet).
- Place the transmitter into its linking mode and turn on the receiver.
- During the transmitter's countdown, press and hold the receiver's tact switch for approximately 2 seconds. The LED will begin to blink red.
- After the receiver LED switches from blinking red to a steady green light, if the transmitter and receiver are linked normally, turn the power switch OFF and then back ON. A green LED indicates successful linking. Verify servo operation.
LED Status and Receiver Condition
| Condition | LED Status |
|---|---|
| No signal reception | LED: Red |
| Receiving signals | LED: Green |
| Unrecoverable failure (EEPROM, etc.) | LED: Red and Green turn on alternately |
Refer to the transmitter's operation manual for detailed instructions on placing the transmitter into linking mode.
Important Note on Linking: If multiple T-FHSS systems are operating nearby, your receiver might have difficulty establishing a link. In rare cases, if another T-FHSS transmitter/receiver is linking simultaneously, your receiver could inadvertently link to the wrong transmitter. This is dangerous if not noticed. To prevent this, always double-check that your receiver is under the control of the intended transmitter.
Usage Condition on "High Speed Mode"
⚠️ CAUTION: When using "High Speed mode", use a Futaba digital servo (including brushless servos). Analog servos cannot be used.
❗ The use of analog servos may cause servo trouble.
Post-Linking Safety
⚠️ WARNING: After linking is completed, cycle the receiver power and verify that the receiver is under the control of the intended transmitter.
Do not perform the linking procedure with the motor's main wire connected or with the engine operating, as this may result in serious injury.
Example of Connection
- Battery: A LiFePO4 Battery (6.6V-1800mAh [FOR EU]) is connected. A note indicates that if all ports are used, connect the battery using a HUB or Y-harness.
- Switch: Connected to the receiver.
- CH2: Connected to the Throttle servo.
- CH1: Connected to the Steering servo.
- S.BUS2 Port: Connected to a HUB.
- Temperature sensor
- RPM sensor
- Voltage sensor
- Other Telemetry sensors (Optional)
Note on Battery: ⚠️ CAUTION: Be sure to use a charger for LiFe only. (Japanese warning: 警告 充電はLiFe対応品をご使用ください。 - Warning: Please use a charger compatible with LiFe.)
