5. Setup Instructions
5.1. Wiring Connections
Proper wiring is crucial for the correct operation of your receiver. Refer to the diagrams below for connecting the power, motor, and servos.
- Connect your 1S LiPo battery to the 1.25mm 2P power connector.
- Connect your brushless motor to the 2.0mm 3P motor connector.
- Connect linear servos to the designated ports: PORT3 ELE (Elevator), PORT4 RUD (Rudder), PORT2 AIL (Aileron).
- The M.BUS / AUX1 port is multi-functional (see section 6.3).
5.2. Auto Binding Operation
The receiver features an auto binding function for convenience, especially when the receiver is installed in a hard-to-reach location within the fuselage. To initiate auto binding:
- Power on the receiver.
- If no signal is detected for 15 seconds, the receiver will automatically enter auto binding mode. The slow flashing LED light will change to a fast blinking pattern.
- Refer to your specific transmitter's instruction manual to complete the binding process.
6. Operation
6.1. SR3X 3-Axis Stabilization Function (G-versions only)
For receivers marked with "G" (e.g., MXL-RX62E-D-G), the SR3X 3-axis stabilization function is integrated. This feature provides enhanced flight stability. It offers three working modes:
- Off: Stabilization is disabled.
- Low Sensitivity: Provides mild stabilization.
- High Sensitivity: Provides strong stabilization.
The mode can be configured via the GUI software (see section 7). The video below demonstrates the effect of the 3-axis function on servo movement.
6.2. TELEM Function (Telemetry)
The TELEM function, supported on Version D and F2 receivers, allows for real-time monitoring of critical flight parameters. This includes:
- Battery voltage
- Receiver working voltage
- Signal strength
- Working temperature
Monitoring these parameters helps prevent flying out of control range and avoids over-discharging of the battery. Note that the effective control range of the TELEM function may vary depending on your transmitter, and it is normal for the receiver's working range to exceed the TELEM function's effective range.
6.3. M-BUS Port Functionality
The M-BUS port on the receiver is a versatile interface with multiple functions:
- Firmware Updating/Function Setup: Connect to a PC for configuration and updates.
- CH5 Signal Output: Provides a signal output for Channel 5.
- SBUS Signal Output: Outputs SBUS protocol signals.
- External Sensor Connection: Designed for connecting future external sensors (under development).
7. Firmware Updating and GUI Setup
7.1. Connecting to GUI Software
To update firmware or configure settings using the GUI software, you will need a USB programmer (e.g., USB MX-PG02). The software can be downloaded from update.crossover-rx.com/mxo.zip.
- Ensure the USB MX-PG02 programmer switch is set to the 'l' position (if applicable for MXL-RX62E-X-G).
- Connect one end of the cable to the M-BUS port on the receiver.
- Connect the other end of the cable to your PC.
- Open the GUI software.
- Select the correct COM port for your connected device.
- Click "Connect". The software will then display the receiver's functional modules and current settings.
7.2. Parameter Setup using CrossOver-RX Tool Software
The GUI software allows for detailed configuration:
7.2.1. Airplane Type Setup
Configure the receiver for different aircraft types:
- Normal: Standard layout for airplanes.
- Single Power Wing-Normal: For single power wings using same-phase servos (e.g., linear servos).
- Single Power Wing-Reverse: For single power wings using reverse-phase servos (e.g., rotation servos).
- V-Tail-Normal: For single power V-tail planes using same-phase servos.
- V-Tail-Reverse: For single power V-tail planes using reverse-phase servos.
7.2.2. Servos Cycle Setup
This setting adjusts the output signal cycle of the servos. The typical range is 10-22ms. If you experience servo overheating or shaking, you can increase this range or consider using a digital servo.
7.2.3. M-BUS.TX Output Setup
Configure the output signal of the M-BUS.TX port:
- SBUS: The M-BUS.TX port outputs an SBUS signal.
- SERVO: The M-BUS.TX port outputs a PWM servo signal.
7.2.4. Output Channel Configuration
For each channel, you can set the output direction:
- Normal: Indicates normal signal output.
- Reverse: Indicates reversed signal output.
8. Troubleshooting
- Receiver not binding: Ensure the receiver is powered on and no signal is detected for 15 seconds to enter auto binding mode. Check your transmitter's binding procedure.
- Servos overheating or shaking: Adjust the "Servos Cycle" parameter in the GUI software to a higher range. Consider using digital servos if the issue persists.
- No motor response: Verify all wiring connections (power, motor, ESC). Ensure the battery is charged and correctly connected. Check ESC calibration if applicable.
- Unexpected flight behavior (with 3-axis function): Review the SR3X 3-axis settings in the GUI. Try adjusting sensitivity or disabling it for testing. Ensure the receiver is mounted correctly and securely.
- TELEM data not displayed: Check if your receiver version supports TELEM (Version D and F2). Ensure your transmitter is capable of receiving and displaying telemetry data. Verify the effective range of the TELEM function.
9. Maintenance
- Keep Clean: Regularly inspect the receiver for dust, dirt, or debris. Use a soft brush or compressed air to clean it.
- Avoid Moisture: Protect the receiver from moisture and extreme humidity, which can damage electronic components.
- Inspect Wiring: Periodically check all wiring and connectors for signs of wear, fraying, or loose connections.
- Secure Mounting: Ensure the receiver is securely mounted within your model to prevent vibrations from affecting its performance, especially for models with 3-axis stabilization.
- Software Updates: Check the official website or GUI software for available firmware updates to ensure optimal performance and access to new features.
