No source No source is connected at the input. Critical,
Reporting
Bad Source Sync An input source is connected but the signal
timing is not recognized. (Unable to input
source due to bad sync measurement.) Critical,
Reporting
No SDI Source Lock
(
not applicable to
VNM 250 )
An SDI source is connected but the signal
timing is not recognized. (An SDI source is
present but the PLL lock failed.) Critical,
Reporting
Unsupported
SDI Mode (

Error The hardware is unable to encode the input
video. Critical,
Reporting
Unsupported Audio
Source The digital audio source has a bad or
unsupported clock rate. Critical,
Reporting
Bad Audio Source The audio source is not valid for the current
video source. Warning,
Reporting
Data Rate Overload The system is not able to process the
