Operation of the external control
1
Set “TYPE SEL.” of “REMOTE SETTING” to “MAKE” or “TRIGGER” in the SET-UP MENU.
2
Short-circuit the 7th pin terminal (ENABLE) to the 8th pin terminal (GND) so that the monitor can be controlled
by the external control.
3
When the “MAKE” system is selected: Operate each function by short-circuiting the corresponding pin terminal
to the 8th pin terminal (GND) or opening it.
When the “TRIGGER” system is selected: Operate each function by pulse control, that is short-circuiting the
corresponding pin terminal to the 8th pin terminal (GND) for about 1 second and opening it.
• When changing the input with MAKE system, only one pin terminal must be short-circuited. (Other pin terminals
must be opened.)
• When selecting the TRIGGER system, you can operate only one function at a time. Operate the functions one
by one.
