眼下, adding a monitor is not feasible.

The current COFDM repeater design does not include any display output interface, and it also does not support video decoding functionality. The repeater works by directly receiving the COFDM data stream from the receiver module, changing the RF frequency, and retransmitting the data exactly as received.

This architecture is intentionally designed to achieve:

• The simplest and most reliable implementation
• 超低延遲
• Minimal processing delay

Since the unit does not decode the video stream internally, there is no video signal available for a local monitor display.

從技術上來說, yes — Ethernet output can be added.

然而, this would require additional software and hardware development, 包含:

• Data buffering and forwarding logic
• Network transmission program development
• 基於Web的設定介面
• IP address and port management functions
• System testing and optimization

Because of the extra development workload, this feature would typically require:

• A sufficient order quantity, 要么
• A separate NRE/development fee

If your project has volume demand or a dedicated budget for customization, we can evaluate this option further.

The COFDM repeater module itself does not include a built-in display or video output interface, so it cannot directly show tuning status or video images. This is because the repeater is designed as a transparent RF relay device that focuses on low latency and real-time frequency translation, without performing video decoding.

然而, the system can still be monitored and optimized in the following ways:

1. LCD Parameter Configuration Tool Board (推薦的)

The repeater can be connected to an external LCD parameter configuration tool board.

Through this tool, you can directly monitor key RF performance indicators such as:

• Received signal strength (接收信號強度指數)
• 訊號品質 (SNR)
• 誤碼率 (BER)
• Link status and other RF parameters

These indicators are commonly used to determine whether the link is properly tuned and operating under optimal conditions.

2. Using an External Receiver for Video Monitoring (可選的)

If real video monitoring is required, you can connect a standard COFDM receiver near the repeater output side.

在這種情況下:

• The repeater still performs RF frequency translation only
• The receiver handles video decoding
• You can connect the receiver to a display or monitor to view the live video

This effectively allows you to check system performance visually if needed.

重要說明

The COFDM repeater itself:

• 做 not support video decoding
• 做 not output HDMI / CVBS / IP video signals
• Only performs transparent RF relay with frequency conversion
