6. Installation and Setup

Follow these steps to properly install and set up your FS-iBH07 expander:

1. Connect to Receiver: Connect the i-BUS2 input port (labeled [8] in Figure 4) of the FS-iBH07 to the i-BUS2 output port of your compatible Flysky receiver using the provided connection cable. Ensure the polarity is correct.
2. Power Connection: Connect a power source (3.5V-9.0V DC) to the power input port (labeled [9] in Figure 4). Ensure the voltage is within the specified range to prevent damage.
3. PWM Device Connection: Connect your PWM-controlled devices (e.g., servos, ESCs) to the desired output channels (labeled [1] to [7] in Figure 4 and Figure 5). Each channel corresponds to a specific PWM output.
4. Secure Mounting: Use the mounting holes (labeled [10] to [13] in Figure 4) to securely mount the expander within your model. Ensure it is protected from vibrations and moisture.
5. Initial Power-Up: Power on your receiver and transmitter. Observe the LED indicator (labeled [14] in Figure 4) on the FS-iBH07. A steady light typically indicates a successful connection and proper operation.

Note: Always refer to your receiver's manual for specific i-BUS2 output details and power supply recommendations.

7. Operation

Once installed and powered, the FS-iBH07 expander operates by converting the i-BUS2 signal from your receiver into individual PWM signals for the 7 output channels. It also allows for the daisy-chaining of other i-BUS2 devices.

• PWM Output: Each of the 7 output ports provides a standard PWM signal, allowing you to control servos, ESCs, or other PWM-compatible devices.
• i-BUS2 Passthrough: The expander acts as a hub for the i-BUS2 protocol, enabling the connection of multiple i-BUS2 devices in series.
• Signal Expansion: This module is particularly useful when your receiver has fewer PWM outputs than required for your model, or when you need to integrate multiple i-BUS2 sensors or modules.

8. Maintenance

To ensure the longevity and reliable performance of your FS-iBH07 expander, follow these simple maintenance guidelines:

• Keep Clean: Regularly clean the exterior of the expander with a soft, dry cloth. Avoid using solvents or harsh chemicals.
• Protect from Moisture: Although rated PPX6 water-resistant, avoid prolonged exposure to water or extreme humidity. Ensure connections are dry before powering on.
• Check Connections: Periodically inspect all wiring and connectors for signs of wear, corrosion, or loose connections. Secure any loose wires.
• Storage: When not in use, store the expander in a cool, dry place, away from direct sunlight and extreme temperatures.
• Avoid Physical Damage: Protect the module from impacts or excessive force, which can damage internal components.
