Why is there no picture on the Lightware Extender video output (receiver)?
- R
  Renee SpencerAug 6, 2025
  If there's no picture on the video output, several factors could be at play. First, ensure all devices, including the extenders, are properly powered by checking and reconnecting them. Verify that all cable connections, including video and optical cables, are secure. Confirm that the correct port is selected in the Crosspoint settings. Check if the laser is disabled in the LINKOUT properties and ensure Autoselect settings are correct if enabled. Also, verify that the output is not muted and that the display can receive the video format by checking the emulated EDID. Finally, ensure HDCP is enabled on the input port if it was disabled.

  If a connected serial device isn't responding, start by checking the cable connections to ensure they are properly fitted and wired correctly. Then, verify that the RS-232 settings on the transmitter, receiver, and connected serial device(s) match, paying close attention to Link and/or Local ports. Finally, confirm that the RS-232 mode (pass, control, or command injection) is correctly configured.

How to fix Lightware SW4-OPT-TX240RAK Extender when no LAN connection can be established?
- H
  Helen GarciaAug 15, 2025
  If you can't establish a LAN connection, it might be due to an incorrect IP address. Try using a dynamic IP address by enabling the DHCP option. If that doesn't work, restore the factory default settings (with fix IP). Also, check for IP address conflicts with other devices on the network.

Why is not the desired picture displayed on the Lightware SW4-OPT-TX240RAK video output?
- R
  Robin WhiteSep 12, 2025
  If the video output shows an undesired picture, it could be because the video output is statically set to a test pattern (no sync screen). Check the 'No sync screen' settings in the LINKOUT properties. Alternatively, if there's no picture on the video source, the video output might be set to a test pattern. In this case, check the video settings of the source.

Why does HDMI output signal contain no audio when using Lightware Extender?
- T
  tricia66Aug 25, 2025
  If your HDMI output signal contains no audio, it might be because the HDMI mode was set to DVI. Check the properties of the output port and set it to HDMI or Auto. It could also be that a DVI EDID is emulated. In that case, check the EDID and select an HDMI EDID to emulate.

What to do if there is no audio present on Lightware SW4-OPT-TX240RAK output?
- C
  Curtis LeonAug 27, 2025
  If there's no audio on the output, first check the crosspoint settings of the audio layer to ensure the correct audio port is switched to the output. Then, verify that the source audio volume is not low or muted by checking the audio settings of the source. Also, confirm that the output port is not muted by checking its properties. Finally, ensure that the analog audio volume is not set too low in the Analog audio input port settings.
