Practical help

Common problems

No signal

Check that the modulation standard of the device is consistent with the received standard.

Connection not available

Check if the PC and device are on the same network segment. If not, add a new network segment in the advanced TCP/IP settings of the PC.

Cannot connect or forgot login

Operate the front panel of the device to restore factory defaults.

Missing program

Check for channel conflicts, verify the video signal input is normal, and restart the device.

Before use

  • Connect IP line from computer/switch to NMS port.
  • Connect ETH port to network streaming IP.
  • Connect RF OUT to MATV network or TV/STB.
  • Connect power supply (DC 12V/2A).
  • Ensure environment is ventilated and dry (0-45°C).
