4. Setup and Installation

4.1 Compatibility

The FS-CEV04 module is compatible with the following Flysky receivers and transmitters:

• Compatible Receivers: iA4B (direct connection), iA6B (direct connection), iA10 (requires conversion cable).
• Compatible Transmitters: FS-i6X, NV14, PL18, iT4S, i10, and above. Note: FS-CAT01 cannot be used with I6/I6X transmitters, but the FS-CEV04 itself is compatible with i6X.

4.2 Physical Connection

1. Connect to Receiver: Connect the FS-CEV04 to the i-BUS port of your compatible Flysky receiver (e.g., iA4B, iA6B). Ensure the polarity is correct. For iA10 receivers, a specific conversion cable may be required.
2. Connect Telemetry Modules (Optional): If you are using additional telemetry modules (FS-CPD01, FS-CTM01, etc.), connect them in a daisy-chain fashion to the i-BUS port of the FS-CEV04. Refer to the specific module's manual for connection order if applicable.
3. Power Supply: The FS-CEV04 draws power from the receiver, which should be supplied within the 4.0-6.5V DC range. Ensure your power source meets these requirements.

4.3 Binding

The FS-CEV04 acts as an extension to your main receiver. Ensure your primary receiver is correctly bound to your transmitter. The FS-CEV04 does not require a separate binding process; it will communicate through the i-BUS protocol once connected to a bound receiver.

5. Operation

Once the FS-CEV04 is correctly installed and connected to a compatible receiver and transmitter, it will begin transmitting data. The 4 channels provided by the FS-CEV04 can be utilized as additional control channels, while the i-BUS port facilitates telemetry data flow.

• Telemetry Data: If other telemetry modules (e.g., FS-CPD01, FS-CTM01, FS-CVT01) are daisy-chained to the FS-CEV04, their data will be collected and sent via the i-BUS system to your compatible Flysky transmitter.
• Monitoring: Refer to your Flysky transmitter's user manual for instructions on how to display and monitor telemetry data. This typically involves navigating through the transmitter's menu system to access telemetry screens.
• LED Indicator: The LED on the FS-CEV04 indicates its operational status. A solid light typically signifies a stable connection and proper operation. Consult your main receiver's manual for specific LED behavior interpretations.

6. Maintenance

• Cleaning: Keep the module clean and free from dust, dirt, and moisture. Use a soft, dry cloth for cleaning. Avoid using solvents or harsh chemicals.
• Storage: Store the module in a dry, cool place away from direct sunlight and extreme temperatures.
• Connection Integrity: Periodically check all connections to ensure they are secure and free from corrosion or damage.
• Firmware: While the FS-CEV04 typically does not require user firmware updates, always ensure your main receiver and transmitter firmware are up to date for optimal performance and compatibility.

7. Troubleshooting

• No Telemetry Data Displayed:
  • Ensure the FS-CEV04 is correctly connected to the i-BUS port of a compatible receiver.
  • Verify that your main receiver is properly bound to your transmitter.
  • Check that any daisy-chained telemetry modules are correctly connected and powered.
  • Confirm your transmitter supports telemetry display and is configured to show the relevant data. Refer to your transmitter's manual.
  • Check power supply to the receiver and modules.
• Module Not Powering On (LED Off):
  • Verify the power supply to your main receiver is within the specified voltage range (4.0-6.5V DC).
  • Check the connection cable between the FS-CEV04 and the receiver for damage or incorrect polarity.
• Intermittent Data:
  • Check for loose connections or damaged wiring.
  • Ensure there is no excessive electrical interference near the module or receiver.
