How to Use the External Control

7 About the External Control
This monitor has the REMOTE (remote) terminal that is used for the operation by an external control.
You can select the following control methods according to the setting of "REMOTE SYSTEM" in SET-UP MENU:
• MAKE (make contact system): Controls the function by short-circuiting the corresponding pin terminal to the GND
• TRG. (trigger system):
NOTES:
When selecting "MAKE" (the make contact system), you can select how to change the input by the external control as follows:
A–D (4-pin control): Changes the input by short-circuiting any one signal line of INPUT A to INPUT D.
A/B (1-pin control): Selects INPUT A or INPUT B by short-circuiting and opening only 2nd pin terminal. In this setting, you cannot change the
input to INPUT C or INPUT D by the external control.
• Opening:
• Short-circuiting: Changes the input to INPUT B

*1 The 2nd pin terminal works to change the input between INPUT A (opening) and INPUT B (short-circuiting) when
"INPUT REMOTE" in SET-UP MENU is set to "A/B."
*2 These pin terminals are not in use when "INPUT REMOTE" in SET-UP MENU is set to "A/B." Do not connect these
pin terminals in such a case.
*3 The 14th pin terminal (External control) should be controlled by the make contact system even when selecting
"TRG." (the trigger system).
*4 Short-circuiting the 14th pin terminal (External control) enables operating other functions listed above by the
external control.
Operation
1. Short-circuit the 14th pin terminal (External control) to the 15th pin terminal (GND) so that the monitor can be
controlled by the external control.
2. When selecting "MAKE" (the make contact system), operate each function by short-circuiting the
corresponding pin terminal to the 15th pin terminal (GND) or opening it.
When selecting "TRG." (the trigger system), operate each function by Pulse control, that is short-circuiting the
corresponding pin terminal to the 15th pin terminal (GND) for about 1 second.
NOTES:
When selecting "MAKE" (the make contact system):
• You cannot use the following buttons on the front panel:
UNDER SCAN, COLOR OFF, ASPECT, INPUT SELECT
"REMOTE ON!" appears on the screen if one of those buttons is pressed.
• When more than one terminal of INPUT A to INPUT D are selected (short-circuited), inputs are given the alphabetical priority (A, B, C, D). (We
recommend using an interlock switch which turns off a switch when another switch is turned on.)
When selecting "TRG." (the trigger system):
• You can use the buttons on the front panel.
• You can operate only one function at a time. (We recommend using a switch which turns on only while it is pressed down.)

Controls the function by inputting the pulse signal instantaneously to the
corresponding pin terminal.
