• GENLOCK CONTROLS
k command is used to read the Genlock status.
Value returned mean: 0 = No Genlock signal
1 = Genlock signal ON and OK
2 = Wrong Genlock signal
I command controls the sub carrier phase (Sc Ph) of the Genlock with 1024 levels from 0 to 1023.
i command controls the Horizontal Synchro phase (H Ph) of the Genlock with 256 levels from 0 to 255.
• INPUT STATUS CONTROLS
This control family is read only. They can’t be preceded with value.
u command returns the UNIT value.
d command returns the DHI value.
The following formula allow to calculate the computer input line frequency (in kHz): UNIT VALUE
DHI VALUE
l command returns the GRT value.
The following formula allow to calculate the input frame frequency (in Hz) : Input Line Frequency (Hz)
GRT Value
t command returns Input signal status.
