III. Working Principle and Applications

3.1 Working Principle

Based on the general logic of 4K video decoding equipment, the INFO-4KP-94161D follows the core workflow of signal access - decoding processing - format conversion - output interconnection:

① Signal Access Stage: Receives encoded video signals transmitted by front-end 4K cameras or video servers through HDMI, SDI, or network interfaces, and simultaneously receives control signals from devices such as PLCs through the RS-485 interface.

② Decoding Processing Stage: The built-in decoding chip decodes signals in coding formats such as H.265, and filters damaged data through the corrupted frame detection module to ensure the quality of the original signal.

③ Format Conversion Stage: Converts the decoded 4K signal into an adaptive resolution and signal format according to the requirements of the back-end display terminal (e.g., HDMI 2.0 output to video wall screens, BNC output to traditional monitors).

④ Output and Interconnection Stage: Transmits the processed video signal to the display terminal, and simultaneously responds to alarm signals according to preset logic to trigger corresponding output actions (e.g., relay closure to activate alarm lights), and uploads the device's operating status to the background management system via Ethernet.

3.2 Application Scenarios

IV. Common Faults and Troubleshooting Methods

Fault 1: 4K Signal Cannot Be Decoded, Output Screen is Black
Possible Causes: Incompatible input signal coding format; poor contact of input interface; saturated decoding resource usage of the device; insufficient specification of signal transmission cables (e.g., non-4K dedicated HDMI cables).
Troubleshooting Methods:
① Verify the coding format of the front-end device to ensure it is a mainstream format supported by the device (such as H.265/H.264), and reconfigure the front-end coding parameters.
② Re-plug the input interface cables, check for bent or oxidized pins on the interface, and clean dust from the interface.
③ Turn off some non-critical channel signals to free up decoding resources; if saturation persists for a long time, increase the number of devices to achieve load sharing.
④ Replace with 4K dedicated transmission cables that meet HDMI 2.0 or higher specifications, ensure the transmission distance does not exceed 15 meters, and install signal amplifiers if the distance exceeds the limit.
Fault 2: Output Screen Freezes, Has Snowflake Noise or Static
Possible Causes: Insufficient network bandwidth (in network transmission scenarios); strong electromagnetic interference in the industrial field; degraded performance due to poor device heat dissipation; poor quality of the video signal source itself.
Troubleshooting Methods:
① Test the network bandwidth to ensure that the 4K signal transmission bandwidth is ≥ 20Mbps; use gigabit Ethernet switches to improve transmission capacity, and enable QoS (Quality of Service) traffic control to prioritize video streams.
② Check whether the device is properly grounded (grounding resistance ≤ 4Ω); replace signal cables with double-shielded cables and keep them away from strong interference sources such as frequency converters and motors (distance ≥ 1.5 meters).
③ Check if the device's heat dissipation vents are blocked, clean the dust, ensure the installation spacing is ≥ 10cm, and install cooling fans in high-temperature environments.
④ Replace the front-end camera for testing to rule out quality issues with the signal source.
Fault 3: Device Cannot Interlink with PLC or Background System
Possible Causes: Mismatched RS-485/Ethernet interface parameters (e.g., baud rate, IP address); incompatible interconnection protocols; reversed polarity of control cables; permission setting restrictions.
Troubleshooting Methods:
① Verify that the RS-485 parameters (baud rate 9600/19200, etc., 8 data bits, 1 stop bit) are consistent with those of the PLC; in Ethernet scenarios, confirm that the device IP and the background system are on the same network segment.
② Confirm that the interconnection protocols supported by the device (such as Modbus, ONVIF) are compatible with the background system, and reconfigure the protocol parameters.
③ Check the A/B polarity of the RS-485 cable and rewire according to specifications.
④ Log in to the device management interface, confirm that the current operating account has interconnection control permissions, reassign permissions, and restart the device.
Fault 4: Device Restarts Frequently or Fails to Power On
Possible Causes: Input voltage fluctuation beyond the allowable range; power adapter failure; activation of the device's internal overheat protection; vulnerabilities in the firmware version.
Troubleshooting Methods:
① Measure the input voltage with a multimeter to ensure it is within the range of AC 100-240V; install an AC voltage stabilizer if the fluctuation is large.
② Replace with a spare power adapter of the same specification for testing to rule out power adapter failure.
③ Clean the device's heat dissipation channels, optimize the ventilation conditions of the installation environment, and avoid deployment in enclosed spaces.
④ Download the latest firmware from the official website (if brand information is available), upgrade the firmware via USB or network, and avoid power interruption during the upgrade process.
