Relay Wait Time
the time from powering the C8405 up till the relay is engaged.
After Power Up To avoid audio interruptions you should not engage the relay before
you are sure that all other equipment in the signal chain is up and
running. Because this is an asynchronous process the relay switch over
causes a glitch in the SDI signal.
Error Detection The serial audio data from the frame bus can be monitored for proper
positioning of an Error-Flag. A bad Error-Flag is an indication that
there is disturbance upstream (input signal, input module,
DSP module).
The Error Detection can be turned Off and On for each input from the
bus. You will see the status on the left hand side:
“Embedder (Bus Status)”. A grey “LED” shows that the detection is
disabled. While green is OK, red indicates an error condition and
yellow indicates a Non Audio signal (e.g. Dolby E stream).
The bus status as well as the SDI input status may be presented to
external monitoring systems via SNMP. The frame controller
summarizes such status information and generates SNMP traps for
the frame as an entity or may activate GPOs (if GPI/O module(s) are
installed). The SNMP manager may afterwards poll the
“modulesStatus” for more detailed status information per input
(see SNMP documentation for details).
Main Input This is a display of the audio busses which have been assigned at the
EMBEDDER page.
Aternative Input For automatic bypass of a (e.g. faulty) processing module or switching
over to an emergency announcement you may set up alternative
inputs. Switch over may be tested with the TEST button.
Auto Mode Enables the automatic switch over in case an error is detected for the
Main Input.
Important Note! Auto Mode is possible only if Error Detection is turned on.
The soft button may be used for testing the switch over function.
