HOW TO USE EXTERNAL CONTROL Ⅵ ABOUT EXTERNAL CONTROL The Multi-Format Monitor has two external control terminals. One is the MAKE/TRIGGER terminal, which allows the monitor to be controlled by the MAKE(make contact) or TRG. (trigger contact) method selected in the function setting. MAKE (make contact system): Controls the function by stable disconnection (terminal open) or short-circuiting (short with GND of 15th terminal) of the controlled terminal. TRG.

The other terminal used for remote control is the RS-232C terminal. This allows the monitor to be controlled by a PC via serial communication.

NOTES: • When more than two terminals are selected (short-circuited) from INPUT A through INPUT F, the signal input is not changed. To control INPUT A through INPUT F, we recommend using the interlock switch, which turns off a switch when another switch is turned on. • When trigger contact is on, and if several terminals are short-circuited simultaneously, proper control cannot be done. It is always necessary to short-circuit one terminal for one operation. Also, use of the Tact Switch is recommended. 20 LCT1117-001C 20 02.6.6, 11:39 AM

HOW TO USE EXTERNAL
CONTROL

ABOUT EXTERNAL CONTROL
The Multi-Format Monitor has two external control terminals.
One is the MAKE/TRIGGER terminal, which allows the monitor to be controlled by the MAKE(make contact) or TRG. (trigger
contact) method selected in the function setting.
MAKE (make contact system): Controls the function by stable disconnection (terminal open) or short-circuiting (short with GND of
15th terminal) of the controlled terminal.
TRG. (trigger system)
: Controls the function by instantaneously (one second) short-circuiting (short with GND of 15th
terminal) the controlled terminal.
* MAKE or TRIGGER are selected from REMOTE SELECT in the setup menu.
* The 14th terminal (REMOTE ENABLE) is always controlled by the make contact system regardless of the REMOTE SELECT
setting.
The other terminal used for remote control is the RS-232C terminal. This allows the monitor to be controlled by a PC via serial
communication.
NOTE:
Control priority is in the following order;
1

HOW TO USE THE MAKE/TRIGGER TERMINAL
Connections
Connect (short-circuit) the 15th terminal (GND) to each of the 1st through 14th terminals in the 3-line
15-pin D-sub connector. The functions of each terminal are listed below.
Operation
1. Set REMOTE ENABLE to ON.
2. Short-circuit or disconnect the desired terminal. (When trigger contact is on, duration of short-circuit is approx. 1 second.)
Changing the Signal Input
1. Set REMOTE ENABLE to ON.
2. Short-circuit the desired INPUT terminal. (When trigger contact is on, duration of short-circuit is approx. 1 second.)
3. Disconnect the INPUT terminal selected above. The signal input is actually changed after the disconnection has been
completed.
NOTES:
•
When more than two terminals are selected (short-circuited) from INPUT A through INPUT F, the signal input is not changed.
To control INPUT A through INPUT F, we recommend using the interlock switch, which turns off a switch when another switch is turned on.
•
When trigger contact is on, and if several terminals are short-circuited simultaneously, proper control cannot be done.
It is always
necessary to short-circuit one terminal for one operation.
Also, use of the Tact Switch is recommended.
