Operation of the external control

1Set “TYPE SEL.” of “REMOTE SETTING” to “MAKE” or “TRIGGER” in the SET-UP MENU.

2Short-circuit the 7th pin terminal (ENABLE) to the 8th pin terminal (GND) so that the monitor can be controlled by the external control.

3When 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.

7Using the RS-232C system

You can control the monitor from a personal computer etc. via the RS-232C terminal.

• Consult your dealer for the details of the external control specification.
