How to Use Multicast on 4K HDMI Extenders | Exvist Support

Multicast Usage of 4K Extender

Multicast Usage Instructions

When using wired transmission (connected via a switch), the multicast protocol supports up to 1 transmitter to 254 receivers.

Steps for Multicast Configuration

1. Enable Multicast Functionality

  1. Check the option to enable multicast on both the transmitter and receiver.

2. Set Multicast Address and Port

  1. All receivers must use the transmitter’s multicast address (default: 224.168.1.166) and port (default: 30000).
  2. Ensure the wired network IP addresses of all receivers (default: 192.168.1.167) are unique to avoid IP conflicts.

3. Avoid IP Conflicts

  1. After setting each receiver’s multicast address, modify its IP address to ensure no conflicts between devices.
Notes
NOTES: Multicast can only be used in SWITCH mode and cannot be used with a router, as routers typically disable multicast functionality by default for security reasons.
