III. TROUBLESHOOTING
Additional tips can be found in the
SmartPanel Configuration and Installation Guide.
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.
Only some of the projector controls work.
The Panel controls the Toshiba through RS-232 and IR. If only a subset of the controls is working,
verify that both types of control wiring are correctly wired.
The Panel keeps turning itself off even though the projector is on.
The Panel turns itself off when power verification indicates that the projector is off. Check to make
sure that any third-party power current sensor is correctly calibrated and wired to the Panel.
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
1.
The Toshiba projector does not allow power verification by RS-232 polling. A third party power
current sensor is recommended.
2.
Control of this projector is through RS-232 and Infrared.
3.
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.
Disabling
the lockout delay will cause potentially confusing Panel behavior.
