Extron Electronics System 5cr Plus - Manual (Page 35)

4-7 System 5cccccrrrrr Plus • Serial Communication
Power-up/down delay, room relay mode, auto-set attenuators, RGB delay, and
miscellaneous options are adjustable only via the Configure Unit control screen.
Refer to the System 5cr Help program for details on setting these options.
Power Up/Down Delay — This feature does not control the projector in any way.
It simulates projector delays from 10 seconds to 5 minutes (adjusted in
10-second increments). For a projector that has a warm-up or cool-down cycle
during which it will not accept commands, adjust the System 5’s power-up or
power-down delay time to match that of the projector. During the delay time,
the Power LED will blink as a reminder to not send commands to the projector.
Room relay modes — Select one of the two room relay modes (latched or
momentary) to change how the room relay operates. The default is
momentary contact for 1/8 second.
•
Select Latched to require a press of the Room button to toggle the relay
on or toggle it off.
• Select Momentary to allow the relay to automatically turn off after a set
period time, of from 1/8 second to 2 seconds. Pressing the Room button
will turn the relay on, and the relay will automatically shut off when the
period ends.
RGB delay — This is used in Triple-Action (video mute) switching. With Triple-
Action switching, the System 5 switches to the new sync signal before
switching RGB (video) signals. That allows the projector to adjust to the new
sync timing during a brief delay before displaying the new picture, which will
appear without glitches. The blanking period (RGB delay time) can be set to a
period from 0 seconds to 5 seconds (in half-second steps) via the Configure
Unit screen.
Saving and restoring configurations
The System 5 can be configured by various means (IR learning, downloading, front
panel adjustment, or combinations of those methods), and the configuration
settings can be saved to a file for later use.
1. In the System 5cr Control Program, select File, then select
Save Configuration as... .
2. Save the file as (filename).sy5. An unlimited number of configuration files can
be saved as long as each file has a unique file name ending in .sy5.
3. To retrieve the configuration from within the System 5cr Control Program,
select File, then select Restore Configuration from... .
