Emergency Alert System Caveat
Emergency Alert System Caveat
There is a potential for conflict if both the automation system and the EAS
event triggers want to control the same resources. To address conflicts,
Maestro will restrict certain automation operations for any keyer(s) /audio
over(s) specified in the Background Buttons table as having a fixed assign-
ment. The automation restriction will be that the following automation
commands will not allow the source to be specified and/or changed on
keyer(s)/audio over(s) with fixed assignments:
• SET_KEY
• MAESTRO_KEYER_SOURCE_REQUEST
• TAKE_XPT
• VID_PSET
• AUD_PSET
• AUD_BPSET
• SET_MIX
• MAESTRO_AUDIO_MIXER_SOURCE_REQUEST
If the automation command has the option to specify a NOOP for the
source argument then that source argument must be set to a NULL in order
to process other arguments. All other automation commands not specifi-
cally mentioned in the list above will be allowed on fixed assignments.
Note If EAS Messaging is configured then Keyer 8 and Audio Over 4 will be EAS
Fixed Assignments and cannot be controlled by Automation commands.
