it. Rotate the DVE video so that the front and back sides
alternate on screen. The sources you selected for front and
back should appear in the DVE at the appropriate times. Also,
if the DVE is equipped with a key channel and it is turned on,
you can press the crosspoint button assigned to the DVE key
input to view the key front/back switch. Note also that the
center of this menu displays "Front" or "Back" for the
appropriate Aux outputs to indicate which side the DVE has
requested via the GPIs.
STEP 12: If the GPI setups are correct, you can use the Disk menu to
save them as Personality menu settings in a PER file for easy
recall later. See the Disk menu description later in this section
for more information. You can save the Aux bus source
settings as a snapshot keyframe or Timeline effect. See Section
10 – Timelines in the 8150 Operations Manual for more
information on saving and recalling snapshot keyframes and
Timeline effects.
NOTE: If the DVE sending the front/back switch signal is
also used in an Effects Loop, the Loop Select pushknob,
which you recall with the Effects Loop Inputs softkey,
overrides the existing source selections. See Section 6 –
System Timing, for more information on effects looping.
Using GPI Outputs
You can send up to eight independent GPIs to other devices as part of a
Timeline effect. The 8150 can fire any or all GPOs (output GPIs) at the
beginning of any keyframe on its assigned Timeline.
This example demonstrates how to assign a GPI output to a keyframe:
STEP 1: In the Personality menu, press the Remote Port Enables
softkey. Toggle the GPIs softkey to On. This activates the GPI
output port.
STEP 2: In the Timeline menu, press the Display Timelines softkey to
view the Timeline graphic display.
STEP 3: Use the PREVIOUS or NEXT buttons (near the fader bar) to
move the Timeline cursor to Keyframe 2.
