Assignment of item priority levels
• When both “MARKER1” and “MARKER2” are ON at the same time, “MARKER1” has priority. However, when
the display aspect is 4:3, the “MARKER1” aspect is 16:9, and the “MARKER2” aspect is 4:3, “MARKER2” is
displayed. In this case, the “MARKER2” background is controlled.
• When “MARKER BACK HALF” and “MARKER BACK BLACK” are simultaneously activated, priority goes to
“MARKER BACK BLACK”.
• When two or more of the following items - “INPUT SEL. VIDEO”, “INPUT SEL. VF”, “INPUT SEL. SDI” and
“INPUT SEL. YP
BPR” - are simultaneously activated, priority goes to the last item activated.
Refer to the following diagram and lower right table for the RS-232C terminal pin arrangement and connections.
