Setting up GPO
To set up GPO, go to the Frame / System / Re-
mote / GPO page.
Fig. 32.: Loudness Pilot GPO page
Two relay-based general-purpose outputs are
available. Use this page to configure them.
GPO 1 and GPO 2 parameters
Use the GPO 1 and GPO 2 parameters to spec-
ify which status information should be transmit-
ted to the GPO pins. Available settings are “Off”,
“Sync LED”, “Alert LED” and “Signal LED”. If you
select one of the three LED options, the selected
GPO pin pair will communicate the status of the
respective Loudness Pilot front panel LED.
Idle State 1 and Idle State 2 parameters
Use the Idle State 1 and Idle State 2 parameters
to specify which state of the respective GPO re-
lay (1 or 2) should represent the inactive state of
the assigned LED/status information. Available
settings are “Open” and “Closed”.
GPO setup example
►
To signal Loudness Pilot Synchronization
Status on GPO relay 1 – see “Sync LED(s) –
SDI versions” on page 25 –, set the GPO 1
parameter to “Sync LED”.
►
If you set Idle State 1 to “Open”, the GPO 1
relay…
– will be open as long as no synchroniza-
tion has been achieved and
– will close when synchronization has been
achieved.
Remote – SDI
Fig. 33.: Loudness Pilot Remote SDI page
Loudness Pilot can process SMPTE2020 meta-
data in the incoming SDI stream.
The “Any SMPTE2020” setting is a straightfor-
ward way to control how Loudness Pilot should
process audio using SDI metadata.
If any SMPTE2020 package is received, Loud-
ness Pilot can be set to bypass specific parts of
the audio processing. As an example: If the in-
coming program audio content is already Loud-
ness-normalized, using the “Any SMPTE2020”
approach is a good way of bypassing unneces-
sary audio processing during transmission.
