If two or more cameras are connected to a
picture on the monitor rolls while switching
B, adjusting the vertical phase (V-phase) of
data value of
switcher and the
from camera A to
the cameras will
probably eliminate the rolling. If this adjustment is necessary,
it should only be performed by qualified technician.
Before making any adjustment, confirm that cameras A and B
are connected to the power supply with the same polarity.
To make an adjustment, follow the steps below.
1. While observing the video output signals from both cameras
on an oscilloscope, press camera A s V-phase control push
button (on back of camera) until vertical sync from both
cameras are in phase,
2. If camera A’s adjustment range is
insufficient, adjust camera B’ s
V-phase control push button
in the opposite direction to camera A
unti I they are in phase.
