• Eyelets
• Wood screws

3. Setup and Connections

The DLPH-3 is designed for straightforward installation. Refer to the diagram below for port identification and connection points.

3.1 Connecting Receivers

• Connect your primary receiver to the RX1 port.
• Connect your secondary receiver to the RX2 port.
• The DLPH-3 operates as a dual Rx link system, providing redundancy.

3.2 Connecting Batteries

• The DLPH-3 features an XT60 connector for battery input.
• It is designed to connect two batteries for enhanced power supply and safety.
• Ensure batteries are compatible and correctly polarized before connection. The system includes protection for connecting different types of batteries, but it is always best practice to use matched batteries where possible.

3.3 Servo and S.BUS2 Connections

• Connect your servos to the designated servo ports (1-10) on the left side of the unit.
• The CH3 port is available for specific channel output.
• Utilize the S.BUS2 port for S.BUS2 compatible devices, allowing for advanced telemetry and control.

3.4 Mounting

Use the provided flange damper, eyelets, and wood screws to securely mount the DLPH-3 within your aircraft. Ensure it is placed in a location that is protected from vibrations and potential damage, and allows for adequate airflow if needed.

4. Operating Instructions

Once all connections are made and verified, the DLPH-3 operates as an electronic switch, managing power distribution to your receivers and servos.

• Power On: Connect your batteries to the XT60 connector. The internal electronic switch will activate, providing power to the connected components.
• Status Indicators: Observe the LEDs for RX1 and RX2 (as shown in Figure 2) to confirm proper receiver connection and status.
• Telemetry: The DLPH-3 features a telemetry function that displays the power supply voltage. This information can be accessed via your compatible Futaba S.BUS2 telemetry system, allowing you to monitor battery health during flight.

5. Maintenance

To ensure the longevity and reliable performance of your Futaba DLPH-3, follow these general maintenance guidelines:

• Keep the unit clean and free from dust, dirt, and moisture.
• Regularly inspect all connections for signs of wear, corrosion, or looseness.
• Avoid exposing the unit to extreme temperatures or direct sunlight for prolonged periods.
• Do not attempt to open the casing or modify the internal circuitry, as this will void the warranty and may cause damage.

6. Troubleshooting

If you encounter issues with your DLPH-3, consider the following troubleshooting steps:

• No Power: Check battery connections, ensure batteries are charged, and verify the XT60 connector is fully seated.
• Receiver Not Responding: Confirm both receivers are correctly connected to RX1 and RX2 ports and are bound to your transmitter. Check the status LEDs on the DLPH-3 for receiver activity.
• Intermittent Operation: Inspect all servo and S.BUS2 connections for secure fit. Ensure no wires are pinched or damaged.
• Telemetry Issues: Verify your S.BUS2 telemetry system is correctly configured and compatible with the DLPH-3.

If problems persist after these checks, contact Futaba customer support or your authorized dealer.
