■ Priority of assigned functions
• When both “MARKER1” and “MARKER2” are activated at the same time, “MARKER1” has priority. However,
when the display aspect ratio is 4:3, the “MARKER1” aspect ratio is 16:9 and the “MARKER2” aspect ratio is 4:3,
“MARKER2” is displayed. In this case, the “MARKER2” background is controlled.
• When “MARKER BACK HALF” and “MARKER BACK BLACK” are activated at the same time, “MARKER BACK
BLACK” has priority.
• During GPI edge operation and two or more of “INPUT SEL. VIDEO”, “INPUT SEL. SDI1”, “INPUT SEL. SDI2”,
“INPUT SEL. YP
BPR/RGB” and “INPUT SEL. DVI-D” are simultaneously activated, priority goes to the last
activated item. During level operation, priority is assigned in the following order: “INPUT SEL. VIDEO”, “INPUT
SEL. SDI1”, “INPUT SEL. SDI2”, “INPUT SEL. YP
BPR/RGB” and “INPUT SEL. DVI-D”.
• When “GAMMA SEL. FILM” and “GAMMA SEL. STDIO/PST” are activated at the same time, “GAMMA SEL.
FILM” has priority.
The following diagram and the table on the lower right show RS-232C terminal pin arrangement and connections.
