III. TROUBLESHOOTING
Additional troubleshooting 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.
The Panel keeps turning itself off even though the projector is on.
If the Panel is configured for use with a current sensor, it will turn itself off when the current sensor
indicates that the projector is off. Check to make sure the current sensor connection is correctly wired.
When I try to turn the projector on, the warming indicator (red LED) blink.
The projector is in the default configured
lockout state
; the Panel is waiting for its internal lockout timer
to expire. This feature protects the projector’s bulb. Be sure to inform your client about this behavior.
The projector remote control doesn’t work.
If the Panel is wired into the Control S port of the Sony projector, the infrared remote control is
automatically disabled. If this is unacceptable, the projector should be controlled with the IR Emitter
instead. For more information see
Section II, Control Wiring
section above, and the
SmartPanel
Configuration and Installation Guide
.
IV. TECHNICAL NOTES
1. Power status feedback via RS-232 Power Polling is not available for the Sony VPL-CX10, as the
projector does not allow for RS-232 communication. We therefore STRONGLY RECOMMEND
using a third-party voltage current sensor (about US$100). For more information on power status
feedback, please see the
SmartPanel Configuration and Installation Guide
.
2. The Sony is controlled via Wired Remote/IR only with this Driver. Either infrared or wired remote may
be wired. A discussion of the advantages of Wired Remote versus IR can be found in the
SmartPanel Configuration and Installation Guide.
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. Also, the projector will
not
allow power to be restored before a minimum delay has expired. Therefore,
disabling the
lockout delay will cause potentially confusing Panel behavior.
