Probable Cause/Troubleshooting
1. Power cycle the radio.
2. Check modulation parameters.
3. Check all other settings.
4. Consult with factory
1. Check for internal loose connectors.
2. Consult factory.
1. Check ASI rate of the encoder and reduce below
or equal to the Max Rate. See Section 5.2; under
GOP settings.
2. Change the modulation parameters to support a
high bit rate. See Section 5.2; under COFDM
Parameters.
NOTE: Link reliability will be reduced as the data
rate is increased.
1. Check external ASI cabling.
2. Check maximum cable length (< 200 Meters).
1. Ensure there are no other Modulator or Encoder
errors.
2. Ensure the audio input is properly selected.
3. Contact the factory.
1. Power cycle the radio.
2. Check modulation parameters.
3. Check all other settings.
4. Consult with factory
1. Ensure audio parameters are set properly.
2. Ensure audio Embedding is enabled on source
device.
3. Consult factory.
1. Power cycle the radio.
2. Consult with factory.
1. Power cycle the radio.
2. Consult with factory.
Consult with factory.
1. Check AES cabling.
2. Check pin-out on cable.
1. Check the audio input selection and ensure it is
set to SDI.
2. Ensure Embedded Group is set to 1.
3. Ensure audio Embedding is enabled on source
device.
1. Check for bad cable or connector.
2. Video standard.
1. Ensure there are no other Modulator or Encoder
errors.
2. Ensure the video input is properly selected.
3. Contact the factory.
