External Control

7About the external control

This monitor has the MAKE/TRIGGER terminal, which allows you to control the monitor by the make contact or the trigger system.

•MAKE (make contact) system: Controls the monitor by short-circuiting the corresponding pin terminal to the GND pin terminal, or disconnecting (opening) it.

•TRIGGER (trigger) system: Controls the monitor by sending the pulse signal instantaneously to the corresponding pin terminal.

Control priority is as follows.

MAKE > TRIGGER/buttons and menu on the monitor

• You can use the external control even when “CONTROL LOCK” is set to “ON” (☞ page 12).

7Using the MAKE/TRIGGER system

The MAKE/TRIGGER terminal is configured as follows. You can assign a function to each pin terminal in “REMOTE SETTING” (☞ “PORT F1” – “PORT F6” on page 12).

• You cannot change the functions assigned to the pin terminals from 7th and 8th.

	Pin No.	Pin name		Pin No.	Pin name
	1	PORT F1		5	PORT F5
	2	PORT F2		6	PORT F6
	3	PORT F3	7		ENABLE*1
This is a female terminal.	4	PORT F4	8		GND

*1 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 7.

1Select “REMOTE SETTING” on the SET UP MENU.

2Select a pin name (“PORT F1” – “PORT F6”) for which you want to assign a function, then select the function you want to assign.

• For selectable functions, see the tables below.

Display	Functions to be controlled	Opening	Short-circuiting
VIDEO 1	Changes the input to “VIDEO 1.”	Invalid	Valid
VIDEO 2	Changes the input to “VIDEO 2.”	Invalid	Valid

•You cannot assign the same function to different pin terminals.

•The TRIGGER system switches each function by short-circuiting the pin terminal for about 1 second and opening it.

*2 Must be controlled with the TRIGGER system.

Operation

1Select the control method (“SYSTEM”) in “REMOTE SETTING.”

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 selecting “MAKE”: Operate each function by short-circuiting the corresponding pin terminal to the 8th pin terminal (GND) or opening it.

When selecting “TRIGGER”: 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 or Picture Mode with the 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.
