Introduction

The AV Access 4KIP200 AV over IP solution is designed for seamless and reliable video distribution, but occasional troubleshooting may be necessary to ensure optimal performance. This guide addresses common issues and provides professional, easy-to-follow solutions.

4KIP200 Troubleshooting Guide

1. What can I do if the VDirector App cannot find any devices?

• Reset all encoders and decoders: Power cycle the devices to refresh their network status.
• Check network IP settings: Ensure that all devices, including the PC/mobile device running VDirector, encoders, and decoders, are on the same local area network (LAN) and have unique IP addresses.
• Verify the broadcast function: Ensure that the broadcast feature on your router or Ethernet switch is enabled, as disabling it may prevent device discovery.

2. What can I do if the VDirector App can detect devices but cannot control them (e.g., switch channels, turn sources on/off)?

• Check device permissions: Ensure that the VDirector app has sufficient permissions to control the devices.
• Verify the network stability: Unstable network connections can disrupt control functions. Use a high-quality Ethernet switch or separate the codecs’ network from other devices.
• Reset the app and devices: Restart the app and all connected devices to refresh their states.

3. What can I do if there is a noticeable delay between the first and last screens in the video wall?

• Optimize the network setup: Use a Gigabit Ethernet switch and ensure sufficient bandwidth for smooth video transmission.
• Check synchronization settings: Ensure all devices in the video wall are properly synchronized and that no unnecessary devices are connected to the network.
• Use direct connections where possible: Reduce latency by minimizing the number of network switches and devices between the encoder and decoder.

4. What can I do if the picture is sometimes partially mosaic?

• Bypass the Ethernet switch: Connect the encoder and decoder directly to isolate the issue.
• Upgrade the network switch: Use an Ethernet switch with higher processing capability to handle data more efficiently.
• Check network conditions: Ensure there’s no network congestion or interference, and reserve some ports on the switch to lower its workload.
• Inspect cabling quality: Test Cat cables and replace any with noticeable wear or poor quality.
• Reduce competing applications: Minimize other bandwidth-intensive applications on the same network to avoid interference.

5. What can I do if there is no sound from HDMI and audio de-embedding output ports?

• Set the audio format: Ensure the input source’s audio is set to PCM format, as some formats may not be supported.
• Direct connection test: Connect the source directly to the display via HDMI to verify if audio is working.
• Inspect device settings: Check the decoder’s audio settings and ensure the output port is properly configured.

6. What can I do if the RS232 connection is not working?

• Verify cable connections: Ensure the RS232 cable follows the correct pinout connection: “TX-RX, RX-TX, GND-GND.”
• Check the baud rate: The default baud rate for the 4KIP200 is “115200.” Ensure this matches the connected device settings.
• Perform a loopback test: Use an RS232 loopback test to confirm functionality.
• Direct connection test: Connect the control and controlled devices directly, bypassing the codecs, to determine if the issue is with the RS232 cable or settings.

7. After the codecs are connected to my home network, the network speed drops significantly. What should I do?

• Use a Gigabit Ethernet switch: Ensure your network switch supports high bandwidth.
• Separate networks: Isolate the codecs on a dedicated local area network to prevent them from affecting your home network.
• Monitor device count: Adding more codecs increases network traffic. Ensure your network infrastructure can handle the bandwidth requirements.

8. There is no video output after I connect the encoder to the decoder directly via a Cat cable. What should I do?

• Reset both devices: Power cycle the encoder and decoder to refresh their connections.
• Check source resolution: Ensure the input source resolution is supported by the decoder (e.g., set it to 1080P for testing).
• Direct source test: Connect the source directly to the display to confirm it’s providing a video signal.
