In the CH. FAIL box:
SDI: Red. Error in the serial digital video signal. This LED lights up when no
signal is present, when the signal does not have the correct binary velocity
or when the cable is too long and the signal arrives with too much
attenuation. Reception of a video signal with EDH or checksum errors in
the audio packets will cause this LED to blink at half-second intervals.
AUDIO 1,
AUDIO 2: Red. These LEDs light up continuously when no signal is present at the
analog audio inputs, and they blink if the corresponding channel has an
overload. AUDIO 1 refers to the first two audio channels and AUDIO 2
refers to the last two. Configuration of the thresholds for detection of a
lack of signal and overload are found in the control registers of the
module. The thresholds for lack of signal and overload come from the
factory configured as -50 dBfs and -1 dBfs respectively.
In the lower box:
1/2/3/4: Green. These LEDs light up at low intensity to indicate which audio groups
are present in the SDI signal. Whichever LED is lit the brightest indicates
the embedded audio group that is currently being embedded.
GROUP SEL.: Pushbutton. This button selects the audio group to be embedded.
4.2. Configuration from the front panel
The SDI stream is capable of carrying up to four audio groups, where each group
contains two or four audio signals that are independently encoded at 20 or 24 bits.
Selection of the group to be embedded is done via the front panel pushbutton or can be
done with a computer when a communications controller module is installed in the
same mounting frame as the AEM3000C01.
The pushbutton operates in the following manner:
1.- Press and hold the button for more than one second to select the group.
2.- The green audio group LED that was brightest will begin to blink at approximately
one-half second intervals, indicating that the module is in configuration mode.
3.- Use brief presses of the button to make the LED corresponding to the audio group to
be embedded blink.
4.- Press and hold the button for more than one second to confirm the selection.
5.- The associated LED stops blinking and the group being embedded changes to the
group with the brightest LED.
The other LEDs lit at lower intensity indicate that the SDI video signal has embedded
audio in the group corresponding to each LED.
