• The 7th terminal and the 8th terminal
are connected.
Operation
1
Set “PARALLEL TYPE” 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 selecting “MAKE” system: Operate each function by short-circuiting the corresponding pin terminal to
the 8th pin terminal (GND) or opening it.
When selecting “TRIGGER” system: 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.
7 Using the serial communication
You can control the monitor from a personal computer etc. via the RS-485 or RS-232C terminal.
• Consult your dealer for the details of the external control specification.

(No. 2), and turning on the monitor (No. 13) can be used while the monitor is off (on standby).
*
1
Enter the monitor’s ID for “ **.” The initial setting of the monitor’s ID is “00.” When connecting several monitors, “00” is a
command for controlling all monitors at once.
