EAS Msg Protect
This option is only available when an EAS licence is installed and stands for
Emergency Alert System Message Protect.
When set to ‘Yes’ and an EAS message crawl is displayed on-air, it will
remain on-air until either an EAS GPI OFF event is triggered, or the user
loads another file from the front panel (manual over-ride). During this period
automation/front panel commands to cut/fade down the crawl will be
ignored. If automation tries to load another file, it will be queued and loaded
after the EAS GPI OFF has been called. The state of the keyer will be
returned to its original state before the EAS GPI ON.
When set to ‘No’ an EAS message crawl is treated just like any other crawl
and can be cut down at any point/replaced.
Timecode Options
To view or change the options, select Timecode options from the System Set-
up menu and press the enter key. The options are contained within three sub-
menus described below.
The hours, minutes and seconds of the time code data are used to form the
displayed time. The second is deemed to start when the frame count in the
time code reaches zero. The effect of this is that 24, 25 and 30 frame systems
all work satisfactorily.
For NTSC systems, "real-time" 30 frames per second time code source will
give the best results. Standard drop-frame time code can be used but will
produce an error of 2.26 frames in 24 hours. "Jam sync" may be used to stop
this accumulating.
Timecode mode
Five options are provided for timecode mode. Use the arrow keys W X so
that the required setting is displayed and press enter to apply that setting.
If the unused option is selected, no external timecode will be used. The
internal battery-backed clock will be used to supply time-of-day information.
This internal clock is not recommended for use in applications other than
testing as this source has relatively poor accuracy.
