How to Use the External Control

7About the external control

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

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

TRIG. (trigger) system: Controls the function by inputting the pulse signal instantaneously to the corresponding pin terminal.

*Select “MAKE” or “TRIG.” from “REMOTE SYSTEM” in the SET-UP MENU.

☞ “REMOTE SYSTEM” on page 16

NOTE:

•When using the make contact system, you cannot use the buttons on the front panel or menu to utilize functions which are controlled through the MAKE/TRIGGER terminal. (When using the trigger system, you can also use those functions using the buttons on the front panel or the menu.)

*1 The TRIG. (trigger) system switches each function by short-circuiting for approx. 1 second.

*2 External control (the 7th pin terminal) is controlled by the MAKE (make contact) system even when you select the “TRIG.” (trigger) system.

Operation

1.Short-circuit the 7th pin terminal (External control) to the 8th pin terminal (GND) so that the monitor can be controlled externally.

2.When selecting the “MAKE” (make contact) system, operate each function by short-circuiting the corresponding pin terminal to the 8th pin terminal (GND) or opening it.

When selecting the “TRIG.” (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.

NOTE:

•When controlling No. 1 to 4 pin terminals by the MAKE (make contact) system, only one terminal must be short-circuited. (Other terminals must be opened.)

•When selecting the “TRIG.” (trigger) system, you can operate only one function at a time. Operate the functions one by one.
