3. Configuració i instal·lació

3.1. Connexió del receptor

Refer to Figure 2 for a detailed identification of the ports on your FS-SR12 receiver:

• LED: Llum indicador d'estat.
• SERVO: PWM output ports for channels 2 through 12.
• SENS: Dedicated sensor port.
• BVD/VCC: Port for Battery Voltage Detection and main power input.
• BIND: Button used to initiate the binding process with a transmitter.
• S+-PPM/1: Multi-function port for Channel 1 PWM output or PPM signal output.

Connect your servos, Electronic Speed Controllers (ESCs), and other compatible devices to the appropriate PWM channels (2-12) and the S+-PPM/1 port for Channel 1 or PPM output. Always ensure correct polarity when connecting power and servos to prevent damage.

3.2. Font d'alimentació

The FS-SR12 receiver requires an input power within the range of 3.5V to 9V DC. Verify that your power source, such as a Battery Eliminator Circuit (BEC) from an ESC or a dedicated receiver battery, supplies voltage strictly within this specified range.

3.3. Col·locació de l'antena

For optimal signal stability and range, the two antennas of the FS-SR12 should be positioned at a 90-degree angle to each other. Ensure they are mounted away from any carbon fiber, metal, or other conductive materials that could potentially shield or interfere with the radio signal. Avoid sharply bending or damaging the antennas during installation.

3.4. Binding Process

To establish a secure communication link between your FS-SR12 receiver and a compatible ANT protocol transmitter (e.g., FLYSKY FS-ST8), follow these steps:

1. Place your transmitter into binding mode. Consult your specific transmitter's instruction manual for detailed steps on how to activate binding mode.
2. While holding down the BIND button on the FS-SR12 receiver, power on the receiver.
3. Observe the LED indicator on the receiver. It will typically flash rapidly during the binding process and then turn solid once a successful connection is established.
4. Once the LED indicates a successful bind, release the BIND button. Power off and then power on both the receiver and the transmitter.
5. After restarting, verify that the receiver is responding correctly to all control inputs from your transmitter.

4. Funcionament

4.1. Signal Output Modes

The FS-SR12 receiver offers versatility with multiple signal output types:

• PWM (modulació d'amplada de pols): Provides direct, individual control for servos connected to channels 1-12.
• PPM (Pulse Position Modulation): A single wire carries all channel data, commonly used for connecting to flight controllers.
• i-BUS: FLYSKY's proprietary serial bus protocol, offering a streamlined connection for multiple channels.
• S.BUS: Futaba's widely adopted serial bus protocol, also used for connecting to flight controllers and other compatible devices with a single wire.

The desired output mode is typically configured through your compatible FLYSKY transmitter's settings or via the flight controller's software. Refer to your transmitter's manual for specific instructions on how to select and configure these output modes.

4.2. Integrated Sensors and Black-Box Function

The receiver's built-in 3-axis gyroscope and 3-axis accelerometer provide real-time data on the model's attitude and motion. This sensor data can be utilized by compatible flight controllers for advanced stabilization and flight control. Additionally, the basic Black-Box function allows for recording and later analysis of flight data, which can be invaluable for tuning and troubleshooting. Consult your flight controller's documentation for details on integrating and utilizing this sensor data.

4.3. Actualització en línia

The FS-SR12 receiver supports online firmware updates, allowing you to keep your device current with the latest features, improvements, and bug fixes. Visit the official FLYSKY website for information on available firmware updates and detailed instructions on how to perform the update process.

5. Manteniment

Adhering to these maintenance guidelines will help ensure the long-term reliability and optimal performance of your FS-SR12 receiver:

• Condicions ambientals: Always operate and store the receiver within its specified temperature range of -10℃ to +60℃ and humidity range of 20% to 95%. Avoid exposing the device to extreme temperatures, high humidity, or rapid temperature changes.
• Neteja: Keep the receiver clean and free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning. Never use solvents, harsh chemicals, or abrasive materials, as these can damage the casing o components interns.
• Protecció física: Protect the receiver from physical shocks, impacts, and excessive vibrations. Ensure it is securely mounted within your model to prevent movement during operation.
• Cura de l'antena: Regularly inspect both antennas for any signs of damage, such as kinks, cuts, or fraying. Damaged antennas can severely degrade signal range and reliability, potentially leading to loss of control. Replace damaged antennas immediately.

6. Solució De Problemes

Sense senyal / Senyal intermitent:

• Verify that the receiver is correctly bound to your transmitter. If unsure, re-perform the binding process as described in Section 3.4.
• Ensure both the transmitter and receiver are powered on and within the effective operating range.
• Inspect the antenna placement and condition. Confirm they are positioned correctly (90-degree angle, away from obstructions) and are not damaged.
• Check that the input power to the receiver is stable and within the specified 3.5V-9V DC range.
• Identify and eliminate potential sources of 2.4GHz interference in your operating environment (e.g., Wi-Fi routers, other RC systems).

Servos Not Responding:

• Confirm that all servos are correctly plugged into their respective PWM channels with the correct polarity.
• Check the signal output mode (PWM, PPM, i-BUS, S.BUS) configured on your transmitter and ensure it matches your receiver and flight controller setup.
• Verify that your transmitter is sending control commands and is not in a failsafe or hold mode.
• Ensure the servos themselves are functional by testing them independently if possible.

Estat del LED del receptor:

The LED on the receiver provides visual feedback on its operational status. Consult your FLYSKY transmitter's manual or the receiver's specific documentation for a detailed explanation of LED indications (e.g., solid light for a successful bind, rapid flashing for binding mode, slow flashing for no signal, off for no power).
