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

PIN3, PIN4, PIN5” in “PARALLEL TYPE” on page 16).
You cannot change the functions assigned to the pin terminals from

The 7th pin terminal makes the external control valid/invalid. Make
sure to control the terminal by the MAKE system.
To assign the functions to the pin terminals
For the operation procedure, see page 12.
1
Select “REMOTE SETTING” on the SET-UP MENU.
2
Set “PARALLEL TYPE” to “SET.”

Select a pin name (“PIN1” – “PIN5”) for which you want to assign
a function, then select the function you want to assign.
For the selectable functions, see the table on page 19.

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.

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 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.
