4.1.3.2. Set the “Manage Power” preference
If the destination that you are creating does not include a Display Manager
then you are finished. Click “Apply” and move on by creating other
destinations or proceeding to Section 4.2.
Assuming the destination does contain a Display Manager, you must define
your preference regarding power management for the Display Manager that
you just created. This can be accomplished by setting the “Manage Power”
checkbox accordingly. If you want Phoenix to automatically power the
associated Display Device ON when an event launches for it, and OFF when
the event expires (assuming the user hasn’t manually turned the destination
ON previously), leave the “Manage Power” checkbox selected. Otherwise,
deselect the “Manage Power” checkbox.
4.1.3.3. Set the “Use PCS” option
If the Display Manager is controlling a projector via infrared
then it is likely that
an AMX Power Current Sensor (PCS) is employed to determine the power
state of the projector. If so, enable the “Use PCS” checkbox. Otherwise,
leave it unchecked.
4.1.3.4. Define the display manager timing parameters
Because different display devices require different IR pulse lengths, different
warm-up timing, etc., you must define the timing parameters that are optimal
to the display device that you are controlling. These timing parameters are
set by defining the CTON, CTOF, PTON, and PTOF settings. These are
terms unique to the AMX Television Managers and are defined as follows (the
following is paraphrased from AMX documentation).
CTON: The IR pulse length used when pulsing channel digits.
CTOF: The pause time between channel digit IR pulses.
PTON: The IR pulse length of the Power On and Power Off commands.
PTOF: The time that the Television Manager will wait before attempting to
change the display device power state if the previous command was
ineffective. This is based off the reading of the sync sensor or the I/O port
that is connected to the Power Current Sensor (depending on the method
used to detect power – see sections 4.1.3.2 and 4.1.3.3 for more information
regarding power sensing). This setting is critical to the proper functioning of
the Television Manager. If the value is too small then the display device may
“cycle,” meaning that the Television Manager will send a command to change
the power state and then, before the device has time to react, the TM will
repeat the command, causing it to revert back to its initial power state. This
may continue infinitely, making the room unusable and possibly damaging the
display device.
If you experience a problem with a display device power state cycling, the two
first things to check are:
• Make sure the sync sensor or power current sensor is properly connected.
When using a sync sensor, the display device power indicator on the front of
the TM should be ON when the display device is ON and OFF when it is OFF.
• Check your PTOF setting.
