Wiring Diagram

Connect the VTX to your Flight Controller (FC) as follows:

Dimensions: The VTX has dimensions of 39.2mm (length) x 29mm (width) x 12.5mm (height), with a mounting pattern of 25.5mm x 25.5mm using M2 screws.

Diagram Description: The VTX unit is labeled with "TOTEM II VTX 2500mW 48CH 5.8GHz MADE IN CHINA". It shows the MMCX antenna connector and the SH1.0mm-6P connector with pins labeled GND, VIDEO, 7-36V IN, GND, RX-IRC, 5V-OUT.

How to Operate

1. Band Switching

Long press the band and channel adjustment button (④) for 5 seconds. The green LED will start blinking. Short press button ④ to cycle through frequency bands (A, B, E, F, R, L). The corresponding blue LED will flash to indicate the selected band: 1 flash for Band A, 2 flashes for Band B, 3 flashes for Band E, 4 flashes for Band F, 5 flashes for Band R, and 6 flashes for Band L.

2. Frequency Channel Switching

Short press the power adjustment button (⑤) to cycle through channels 1 to 8. The green LED will flash each time the button is short-pressed, with the number of flashes indicating the channel: 1 flash for CH1, 2 flashes for CH2, ..., 8 flashes for CH8.

3. Power Output Switching

Short press the power adjustment button (⑤) to cycle through power levels: 25mW, 400mW, 800mW, 1500mW, and 2500mW. The red LED will flash to indicate the selected power level: 1 flash for 25mW, 2 flashes for 400mW, 3 flashes for 800mW, 4 flashes for 1500mW, and 5 flashes for 2500mW.

Pit Mode: Long-press the power adjustment button (⑤) for 5 seconds to enter or exit Pit mode. When Pit mode is activated, the red LED remains on continuously, indicating minimal power output for safe setup.

Band and Frequency Table

Frequencies are listed in MHz and comply with FCC Certification Standard.

Note: Some channels/bands may not be populated in the provided table.

Betaflight Configuration

To configure the TOTEM II VTX using Betaflight Configurator:

1. Connect your flight controller to your computer and open Betaflight Configurator.
2. Navigate to the "Ports" tab.
3. Find the appropriate UART port used for VTX control (e.g., for SmartAudio or IRC Tramp). Select "IRC Tramp" from the dropdown menu for the "Peripherals" setting.
4. Click "Save" and then "Reboot" the flight controller.
5. After rebooting, go to the "Video Transmitter" page in Betaflight Configurator.
6. Click "Load from file" to upload a configuration profile.
7. Locate the corresponding .json suffix map transfer profile file (e.g., "TOTEM 5.8Ghz 2.5W VTX Configuration file.json").
8. Click "Open" to load the file.
9. Click "Save" after loading the configuration profile to apply the settings.

Precautions

• Antenna Connection: Always ensure an antenna is securely plugged into the VTX before powering it on. Failure to do so can damage the VTX components.
• Heat Dissipation: The VTX may generate high temperatures during operation. Avoid touching it directly to prevent burns. Ensure adequate airflow around the module for proper heat dissipation.
• Regulatory Compliance: When using this product, please comply with all local radio laws and regulations. Use only locally allowed channel frequencies.
• Power and Polarity: Before powering on, verify the input voltage is within the 7-36V range and that the positive and negative poles are connected correctly to avoid damaging the components.
• Antenna Quality: Use high-quality antennas to ensure effective image transmission performance.
• Static State: If the image transmitter remains in a static state for an extended period after being powered on, set the power output to the minimum level to prevent overheating.
• IRC Tramp Control: When utilizing the IRC Tramp protocol, adjustments to frequency band, channel, or power settings cannot be made directly via the VTX buttons. These changes must be configured through the Betaflight Configurator or via the On-Screen Display (OSD) interface using your remote control.

Disclaimer

Before using this product, please carefully read and follow all safety and compliance guidelines provided in this document and related to the product. The video transmission is set to a default power of 25mW. Operating at power levels beyond 25mW requires an HAM license or approval from local authorities. Please ensure you are using legal frequencies and refer to the Betaflight VTX chart provided for your specific region.

FCC Warning
