Power Up/Down Delay times
1
Many projectors (LCD, DLP, etc.) have a warm-up and cool-down cycle.
During these times, the projector may not accept commands. The times
for each projector may be different. The System 5 has timers that can be
adjusted to represent these delay times, thereby warning the operator not
to send commands while the Power LED is blinking. Slide the scroll bar
for Pwr-Up Delay and/or for Pwr-Dn Delay to match the times required by
the projector being used with the System 5. These settings determine how
long the Display Power LED on the front panel blinks during power up and
power down of the projector. These settings do not control the projector
times; they simulate it. Settings are from 10 to 300 seconds (5 minutes),
in 10 second steps. The factory default is 30 seconds.
Auto Set Attenuators (set all audio input to the same level)
2
With the audio input sources active, click this button to automatically
preset each input to its “Clip” level. Once this is done, the Volume control
(from the front panel, a host or remote SCP 100) will operate as the
master Volume control.
Room Relay Mode (Latched/Momentary)
3
This allows the selection of two modes for customizing the operation of
the Room control function. Depending upon what the designer wants the
function to control, it can operate in either of two ways.
• Latched – click this button to make the Room button operate as follows:
press to activate the relay and press again to deactivate (unlatch) it.
• Momentary – click this button to make the Room button operate as
follows: press the Room button to activate; deactivation takes place after
a prescribed time, as set by sliding the scroll button up or down. The time
value is displayed from 1/8 to 2 seconds, in 1/8 second steps.
________ The Windows® Control Program is the only way to adjust the time
duration for this mode.
Figure 4-5. Example of the System 5 operational screen.
In the System 5 Control program, select one of the Room Relay Mode
buttons. If Momentary is selected, move the scroll bar and observe the
time duration displayed in the box below the scroll bar. Settings are from
1/8 to 2 seconds, in 1/8 second steps. Factory default is for Momentary
Mode at 1/8 second. Thus, when the Room button is pressed, the relay is
active for 0.125 seconds and then becomes inactive.
