Rear Panel –Triggers
To use the automatic lens trigger, with a projector or scaler equipped with an external 12V lens trigger, use
a standard double-ended 3.5 mm (1/8 inch) male mono or stereo jack cable. Simply plug the cable into the
projector or scaler lens trigger jack, and then into the ATH2 +12V Trigger In jack. Follow projector or
scaler instructions to configure the lens trigger to send the lens in when the vertical strectch aspect ratio is
selected on the projector. Any voltage change (12V to 0V, 0V to 12V) will automatically turn the sled on
causing it to move to the designated position. When using the trigger, the remote control is not required
after configuration.
NOTE: Plugging a live trigger in will automatically turn the sled on and cause it to move. Stand clear of
the lens path when inserting the trigger cable
.
The
Trigger In
(tip positive) operates as follows:
+12V LENS IN
0V
LENSOUT
NOTE: The input trigger jack may be temporarily overridden by the remote control. When the next
change of voltage at the trigger occurs (up or down), the projector or scaler will take control of the sled.
Optionally, you may use the +12V Trigger Out jack on the rear of the device to control motorized screen
masking. The output jack is toggled to +12V whenever the sled is in the LENS OUT position. The output
trigger voltage is toggled when the lens begins traversal so that masking and lens movement may be
overlapped. Maximum output current is 100mA which is sufficient for most masking screen control
modules. The sled is configured to trigger the masking in when the lens it out, so the signal is opposite the
input trigger.
The
Trigger Out
jack (tip positive) is intended to for use with external masking screens, It operates as
follows:
+ 0V Lens is moving to, or is in the LENS IN position. Note this is the inverse of the input signal.
+12V
Lens is moving to, or is in the LENSOUT position. Note this is the inverse of the input signal.
The equipment control port is used by OEM projector manufacturers for custom control options. It can be
ignored by installers.
