Wh at i s S.BU S?
Different from conventional radio control systems the
S.BUS
system uses data communication to transmit control signals from
a receiver to a servo, gyro, or other
S.BUS
compatible device. This
data includes commands such as “move the channel 3 servo to
15 degrees, move the channel 5 servo to 30 degrees” to multiple
devices. The
S.BUS
devices execute only those commands for their
own set channel. For this reason, it can be used by connecting
multiple servos to the same signal line.

The Futaba R6208SB is an S.BUS compatible/FASST-2.4GHz (Multi-ch) system 8-channel high-speed receiver. It features a dual antenna diversity system for enhanced signal reception.

Function Description:

The R6208SB serves as a central component in radio control systems, receiving control signals from a Futaba FASST-2.4GHz transmitter and relaying them to servos, gyros, and other S.BUS compatible devices. It offers both an S.BUS system output port and conventional system channel outputs (1 to 8), allowing for compatibility with both S.BUS compatible devices and traditional servos. The receiver supports two operating modes: "Normal mode" and "High-speed mode." In high-speed mode, channels 1 to 6 can be used with Futaba digital servos (including brushless servos) or S.BUS servos. Channels 7 and 8, however, operate in normal mode regardless of the selected speed setting.

The S.BUS system, unlike conventional radio control systems, utilizes data communication to transmit control signals. This means that multiple S.BUS devices can be connected to the same signal line, and each device will execute only the commands designated for its specific channel. This simplifies wiring and reduces clutter in the model. The R6208SB can also be used in conjunction with conventional servos. For setups requiring servos with a remote battery pack, the S.BUS Hub with Cable (2-way/remote battery pack use) is recommended.

Important Technical Specifications:

• System Compatibility: S.BUS compatible/FASST-2.4GHz (Multi-ch) system
• Channels: 8 channels
• Operating Modes: High-speed receiver
• Antenna System: Dual antenna diversity
• Dimensions: 0.98 x 1.86 x 0.56 inches (24.9 x 47.3 x 14.3 mm)
• Weight: 0.49 oz. (13.8g)
• Power Requirement: 3.7V to 7.4V (Voltage range: 3.5 to 8.4V)
  • Note: When using ESC's regulated output, the capacity of the ESC must meet the usage condition.
• Battery F/S Voltage: Set for 4-cell NiCd/NiMH battery. The Battery F/S function may not work properly with other battery types.

Usage Features:

Operating Mode Selection:

The receiver ships in "Normal mode." To change the mode:

1. Turn off the receiver.
2. Press and hold the Link/Mode switch while turning on the receiver. Keep the switch held for more than one second. The LED will flash, indicating the current status.
3. Release the switch.
4. Turn off the receiver. This process toggles between "Normal mode" and "High-speed mode." The LED status indicates the mode: Red Blink for Normal mode, Green/Red Blink for High-speed mode. After the mode change, the LED will be solid Red for Normal mode or solid Green/Red (Orange) for High-speed mode (changing to Red after two seconds).

High-Speed Mode Caution:

When using high-speed mode, only Futaba digital servos (including brushless servos) or S.BUS servos should be connected to conventional system channels 1 to 6. Analog servos are not compatible with high-speed mode on these channels and their use may cause servo trouble. If analog servos are used, select "Normal mode" and use channels 7 and 8.

S.BUS Servo Channel Setting:

S.BUS servo channels can be set directly at the R6208SB receiver:

1. Connect the accessory short-plug to the DATA port of the receiver. Important: Only connect the short-plug for S.BUS servo channel setting; do not connect it normally.
2. Connect an S.BUS servo to the conventional system output connector (1 to 8) corresponding to the desired channel.
3. Turn on the receiver. The channel setting is completed in Mode A upon power-on. To switch to Mode B (channels 9-16), press the Link/Mode button until the red and green LEDs blink simultaneously.
   • Mode A (channels 1-8) is indicated by the red LED blinking three times.
   • Mode B (channels 9-16) is indicated by the green LED blinking three times.
4. Turn off the receiver.

Linking to the Transmitter:

To link the receiver to the transmitter:

1. Press and hold the Link/Mode switch for more than two seconds.

• Warning: Do not perform the linking procedure with the motor's main wire connected or the engine operating, as this may result in serious injury.
• After linking, cycle receiver power and verify that the receiver is under the control of the linked transmitter.

Re-adjusting F/S Position (for TM-8 only):

To re-adjust the Fail-Safe (F/S) position for the TM-8 transmitter:

1. Press and hold the Link/Mode switch for between one and two seconds.

S.BUS Connector Insertion Precaution:

It is crucial to insert connectors correctly into the S.BUS port. Inserting a connector incorrectly (e.g., reversed or misaligned) can cause a short-circuit across the battery terminals, potentially leading to abnormal heat, fire, and burning. Always ensure proper orientation.

Compliance Information (for U.S.A.):

The Futaba R6208SB complies with Part 15 of the FCC Rules. Operation is subject to two conditions: (1) the device may not cause harmful interference, and (2) the device must accept any interference received, including interference that may cause undesired operation. The responsible party for compliance is FUTABA Corporation of America.

Maintenance Features:

The receiver does not have specific user-serviceable maintenance features beyond proper handling and connection. Regular checks of the LED indicators provide diagnostic information about the receiver's status:

• Solid Green/Solid Red: Initializing
• Off/Solid Red: No signal reception
• Solid Green/Off: Receiving signals
• Blink Green/Off: Receiving signals but ID is unmatched (indicating a need to re-link).

Ensuring the correct battery type (4-cell NiCd/NiMH) is important for the proper functioning of the Battery F/S feature. Using other battery types may prevent this function from working correctly.
