Table 2: Projector power states
Panel vs. Projector Power
The Panel attempts to remain in sync with the Projector it controls at all times. When the projector
is on, the Panel should be on, and vice versa. Therefore, “Panel power” and “projector power” are
used somewhat interchangeably.
Power Status Indicators
Projector power states are generally communicated to the user with indicators on the projector
itself. However, these indicators (usually LEDs) are invisible to anyone holding a remote twenty
feet away.
To alleviate user confusion about power states, there are two power status indicators on the
SmartPanel that communicate the projector’s power state:
x
a red LED acts as a Warm-Up indicator, and
x
a green LED acts as Ready indicator.
The Ready indicator comes on when the Panel believes the projector is on and controllable. It
stays on as long as this is believed to be the case.
Note: When the Panel is waiting for the projector bulb to strike the Ready light remains dark and
the projector cannot be controlled. Most projectors do not accept control during this time.

During lockout, the power-on command is queued; it is not sent until delay expires. Pressing Off
cancels queued power-on requests.

In download-only mode, no communication takes place with the projector; therefore, buttons
perform only cosmetic functions (e.g., selecting an input changes the input displayed on the Panel,
but not command the projector to switch inputs). Relays, however, function normally.
