Outputs
» Motion Control Port: Mating connector is either a stereo or mono 3.5 mm Φ plug. See section Motion Control Output for
more information.
LED Indications
There are two LEDs on the unit which are used to indicate its status and mode:
» Green LED: STATUS LED. Indicates the status of the unit and used to identify errors.
» Amber LED:
SYNC / 3D MODE LED. Indicates the mode in which the unit is currently operating. Additionally, the operation of
the unit’s cooling fan should be observed to determine which mode the modulator is operating in - see section Cooling Fan .
LED indications given in below table can be encountered. For more information about different states corresponding to below LED indica-
tions see the rest of this manual.
GREEN LED AMBER LED UNIT MODE AND STATUS
OFF OFF
The unit is not operating. Either its power is unplugged or an unexpected error occurred
and a hard reset must be made by removing and reapplying power. Cooling fan is off.
ON OFF
The unit’s mode control source is set to “Network” or “GPIO”. The unit can be in 2D or 3D
mode (this is determined by observing the cooling fan operation - see section
Cooling
Fan
). If the unit is in 3D mode (fan is operating), then no valid 3D sync signal is present.
ON
BLINKING
(1s ON, 1s OFF) The unit’s mode control source is set to “frame sync”, it is in 2D mode and scanning for a condition
to transition into 3D mode. This condition is a valid 3D synchronization signal on the GPIO port.
ON ON Normal 3D operation. The unit is in 3D mode and a valid 3D synchronization signal is detected.
BLINKING BLINKING
Simultaneous short blinking once every second of both LEDs indicates
the device has encountered an error. A reset is required. The power
supply should be unplugged for 5 s and then plugged back in.
BLINKING BLINKING
Alternating blinking of both LEDs indicates a start-up routine. When the unit is powered up it goes
through an initialization sequence during which both LEDs blink out of phase for approximately 5 s.
BLINKING BLINKING
Simultaneous fast blinking of both LEDs indicates the unit has entered the
“factory reset routine”. See section Factory Reset for more information.
Cooling Fan
The cooling fan MUST be operating when the modulator is exposed to light from the projector lamp. Exposing the modulator to light from
the projector when the modulator is off or in 2D mode will result in heat damage to the LC shutter assembly. To avoid such damage, the
modulator’s cooling fan always turns on when operating in 3D mode. When the modulator is operating in 2D mode the cooling fan is off;
therefore, cooling fan operation is a clear indication of which mode the modulator is operating in at any given time.
If the fan is ON, the unit is set to 3D mode. If the fan is OFF, 2D mode is selected and the modulator must not be exposed to the
light coming from the projector!
