Introducció
The Flysky FS-SR8 is an advanced 8-channel receiver designed for use with RC transmitters utilizing the ANT protocol, specifically compatible with the FS-ST8. This compact receiver features two external antennas for enhanced signal reception and supports bidirectional transmission, allowing the transmitter to display returned information from the receiver after two-way binding. It is versatile, adapting to a wide range of models including fixed-wing aircraft, helicopters, gliders, delta-wing airplanes, multicopters, racing drones, engineering vehicles, nest boats, robots, and cars.
Key features include PWM/PPM/i-BUS/S.BUS data output, a wide input power range of 3.5V to 9V DC, and robust construction for reliable performance.
Informació de seguretat
Si us plau, presteu atenció al voltage and safety when using this device. Ensure correct polarity and voltage within the specified range (3.5V~9V/DC) to prevent damage to the receiver or connected components.

- SERVO: Standard servo output channels (1-8).
- SENS: Sensor input port.
- BVD/VCC: Voltage Detection / Power Input.
- BIND: Binding port/button for pairing with transmitter.
- S+- PPM/1: Multi-functional port for S.BUS, PPM, or Channel 1 output.
Configuració
Procediment vinculant:
- Ensure your FS-ST8 transmitter is powered off.
- Connect power to the FS-SR8 receiver (3.5V~9V/DC). The LED on the receiver should start flashing, indicating it's ready for binding.
- Premeu i manteniu premut el botó BIND del receptor.
- While holding the BIND button, power on your FS-ST8 transmitter.
- The LED on the receiver should change to a solid light, indicating successful binding. Release the BIND button.
- Apagueu i torneu a apagar l'emissor i el receptor per confirmar l'enllaç.
- The FS-SR8 supports both one-way and two-way binding. For two-way binding, the transmitter will display telemetry information returned from the receiver.
Col·locació de l'antena:
Proper antenna placement is crucial for optimal range and signal reliability. Position the two antennas at a 90-degree angle to each other, away from carbon fiber, metal, or other conductive materials that could shield the signal. Ensure the antenna tips are exposed and not bent sharply.
Connecting to Flight Controller/Servos:
Connect the receiver's output ports (PWM/PPM/i-BUS/S.BUS) to your flight controller or servos according to your model's wiring diagram. Refer to your flight controller's manual for specific connection details for each data output type.

Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Receiver LED not solid after binding | Binding failed; Transmitter not in binding mode; Receiver not powered correctly. | Re-attempt binding procedure carefully. Ensure transmitter is in binding mode. Check receiver power supply. |
| Loss of signal/short range | Poor antenna placement; Interference; Damaged antenna. | Adjust antenna position (90-degree angle, away from carbon/metal). Avoid operating near strong RF sources. Inspect and replace damaged antennas. |
| No response from servos/flight controller | Incorrect wiring; Receiver not bound; Flight controller not configured correctly. | Verify all wiring connections. Ensure receiver is successfully bound. Check flight controller settings for correct receiver protocol (PWM/PPM/i-BUS/S.BUS). |
| El receptor no s'encén | Vol incorrectetage; Reversed polarity; Faulty power source. | Comproveu el volum d'entradatage (3.5V~9V/DC). Verify polarity. Test with a different power source. |
