Which input can be used as an alternative to view native 380-HD video when the main processor fails?

• A. COM input
• B. HDMI input
• C. USB input
• D. VGA input

Answer: (A)

When a mission-critical video system loses its main processing stream, having a direct, non-processor-dependent input path is essential to keep viewing the native feed. The COM input serves as that bypass route, delivering the 380-HD video signal straight to the display even when the primary processor is down. This preserves access to the essential video without waiting for the main system to recover.

HDMI, USB, and VGA inputs are typically tied to the output or processing chain of the main processor. Without the processor, those paths may not provide a valid or native 380-HD signal, or may require the processor to reinitialize, leading to a loss of video. The COM input is designed to remain available as a standby channel, ensuring continuous visibility of the critical video when the primary path is unavailable.
