8. Troubleshooting

If you encounter issues with your AVmatrix SC1112, refer to the following troubleshooting guide:

• No Video Output on HDMI Display:
  • Ensure the SC1112 is powered on (POWER LED illuminated).
  • Verify all SDI and HDMI cables are securely connected.
  • Check if the HDMI display is set to the correct input source.
  • Confirm the SDI source is active and outputting a valid signal.
  • Try a different HDMI cable or display to rule out cable/display issues.
• Intermittent Video Signal / Blinking:
  • Ensure the power supply is stable and sufficient (5V). Try a different USB power source.
  • Check SDI cable quality and length. Long or low-quality SDI cables can cause signal degradation.
  • Verify the SDI input signal is within the supported specifications (SD/HD/3G-SDI up to 1080p60).
• No Signal on SDI Loop Out:
  • Ensure a valid SDI signal is connected to the SDI IN port. The loop-out is dependent on a valid input.
  • Check the BNC cable connecting to the loop-out device.
