IV. TROUBLESHOOTING
Addition tips can be found in the SmartPanel Configuration and Installation Guide.
The Panel powers the projector on, but then the Panel does not respond!
If the projector STANDBY MODE is not configured to NETWORK ON, the projector may stop
responding to RS-232 control. To restore control, the projector must be manually turned off and
unplugged. See Special Control Note 1 in Section II, Control Wiring above.
If the projector firmware version is less than 2.05, then in some circumstances the projector may stop
responding to RS-232 commands even if STANDBY MODE: NETWORK ON is set. See Section III.
Projector Firmware Note above.
The projector is not responding to Panel control!
Several menu settings must be configured for the Epson to work with the SmartPanel. See Special
Control Notes 1 and 2 in Section II above.
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. If the Panel turns itself off after a long delay of several
minutes or more, then the Panel may be configured with the optional Automatic Shutdown Timer.
For more information, see the SmartPanel Configuration and Installation Manual.
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 protects the projector’s bulb. Be sure to let your client know about this behavior.
V. TECHNICAL NOTES
1. 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 Epson power off, the Panel will detect this and power off within twenty
seconds. Should it power on, the Panel will detecting this and power on within thirty seconds.
2. The Epson is completely controlled via RS-232; IR/Wired Remote control does not have to be wired
for this Driver. However, we always recommend wiring both RS-232 and Wired Remote/IR in case
the Driver or projector specifications change.
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.
