SmartPanel Projector Driver Application Note

III. TROUBLESHOOTING

Addition tips can be found in the SmartPanel Configuration and Installation Manual.

The Panel does not do anything at all.

When power is applied to the Panel it should run through a brief power on self-test, during which all of

the Panel lights will turn on and off in sequence. If you do not see this self test, make sure power is

connected correctly and that polarity is correct.

The Panel keeps turning itself off even though the projector is on.

The Panel turns itself off when power polling indicates that the projector is off. Check to make sure

the RS-232 connection is correctly wired (it is extremely unlikely other control would work, and power

polling not).

When I try to turn the projector on, the warming indicator (red LED) blink.

The projector is in the default configured lockout state, and the Panel is waiting for its internal lockout

timer to expire. This feature protects the projector's bulb. Be sure to let your client know about this

behavior.

IV. TECHNICAL NOTES

By default, projector power is verified by polling every few seconds via the RS-232 port. Power

polling can be suspended by depressing and holding the On key; polling will be restored when the

key is released. Should the Sharp power off, the Panel will usually detect this condition and power

off within twenty seconds. Should the Sharp power on, the Panel will usually detecting this condition

and power on within ten seconds.

The Sharp is controlled via both IR/Wired Remote and RS-232. We recommend Wired Remote

control as it is generally more robust. However, use of the Wired Remote will prevent use of the

Sharp's remote control. A complete discussion of the relative advantages of IR vs. Wired Remote

can be found in the SmartPanel Configuration and Installation Manual.

The lockout timer specifies the amount of time allowed between sending POWER OFF and POWER

ON to the projector (the delay allows the projector bulb to cool before re-powering). This delay can

be configured using the Configuration Utility; however, adjusting the lockout timer delay is

strongly discouraged as rapid re-powering causes undue wear on the projector's bulb. Also, the

Sharp will not allow power to be restored before a minimum delay has expired. Therefore,

disabling the lockout delay will cause potentially confusing Panel behavior.
