Wiring Diagram

Connect the supplied multi-wire cable to the transmitter's pin header according to the following pinout:

Ensure correct polarity when connecting power. Incorrect wiring can damage the transmitter.

Antenna Connection

Carefully screw the supplied RP-SMA antenna onto the transmitter's antenna connector. Ensure it is finger-tight to prevent signal loss. Never power on the transmitter without an antenna connected, as this can permanently damage the device.

Operating Instructions

Powering On

Once all connections are secure, apply power (7-24V DC) to the transmitter. The LED display will illuminate, indicating the current channel and band.

Changing Channels and Bands

The TX526 features a single button for controlling channel and band selection.

• Short Press: A short press of the button will cycle through the channels (1-8) within the current band. The LED display will update to show the new channel number.
• Long Press (2-3 seconds): A long press of the button will cycle through the available frequency bands (A, B, E, F, R). The LED display will show the band letter (e.g., 'A', 'b', 'E', 'F', 'r') for a moment before returning to the channel number.

Refer to the frequency table below for specific frequencies per channel and band.

Changing Power Output

The TX526 allows switching between 25mW, 200mW, and 600mW output power. The method for changing power output is typically a very long press or a specific button combination. (Note: Specific button sequence for power output change is not detailed in provided images. Refer to the physical manual for precise instructions.)

Higher power output provides greater range but consumes more battery and generates more heat. Always ensure adequate airflow around the transmitter, especially at higher power settings.

Maintenance

• Keep the transmitter clean and free from dust and debris. Use a soft, dry cloth for cleaning.
• Avoid exposing the transmitter to extreme temperatures, humidity, or direct sunlight.
• Ensure all connections (antenna, power, video) are secure before each use.
• Regularly inspect the antenna for damage. A damaged antenna can significantly reduce performance.
• Do not attempt to open the transmitter casing, as this may void the warranty and cause damage.

Troubleshooting

No Video Signal

• Check all wiring connections, especially power and video input.
• Ensure the antenna is securely connected to the transmitter.
• Verify that your FPV receiver is on the same frequency and band as the transmitter.
• Confirm that the FPV camera is powered and functioning correctly.
• Check the power output setting; a very low setting might result in poor range.

Poor Video Quality / Static

• Ensure there are no obstructions between the transmitter and receiver.
• Check for interference from other 5.8GHz devices or strong Wi-Fi signals.
• Verify that both transmitter and receiver antennas are correctly oriented (e.g., vertical polarization).
• Consider increasing the power output of the transmitter if range is an issue.
• Inspect antennas for damage or bends.

Transmitter Overheating

• Ensure adequate airflow around the transmitter, especially when operating at 600mW.
• Avoid enclosing the transmitter in tight spaces without ventilation.
• Confirm the input voltage is within the specified 7-24V range.
