This monitor has three external control terminals.
●
MAKE/TRIGGER terminal (RJ-45): The following external control
systems are available.

Control priority is as follows.
MAKE > TRIGGER = serial communication = buttons and menu on
the monitor
MAKE > TRIGGER = serial communication = buttons and menu on

You can use external control even when “CONTROL LOCK” is set to
“VOL.LOCK” or “ALL LOCK.” (→ page 25)

When the monitor is off (on standby), external control is not
available. But certain external controls (starting/terminating
communication, turning on the monitor) are available through the
serial communication. (→ page 29)

Using the MAKE/TRIGGER
system
The MAKE/TRIGGER terminal is configured as follows.
You can assign a function to each pin terminal in “REMOTE SETTING.”

Make sure to control the terminal by the MAKE system.
To assign the functions to the pin terminals
For the operation procedure, see page 18.
1 Select “REMOTE SETTING” on the SET-UP MENU.
2 Set “PARALLEL TYPE” to “SET.”

For the selectable functions, see the table on page 29.
Operation of the external control
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.

(GND) or opening it.
When the “TRIGGER” system is selected:
Operate each function by pulse control, that is short-

terminal (GND) for about 1 second and opening it.
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.
