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 functions either by short-circuiting (short with GND of 15th terminal) or stable disconnection (terminal open) 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 SYSTEM in the setup menu. The other terminal used for remote control is the RS-485 terminal, and this allows the monitor to be controlled by serial communication. NOTE: Control priority is in the following order; 1 MAKE/TRIGGER terminal > 2RS-485 terminal > 3 front panel buttons. When trigger contact is on, the front panel buttons can be operated.

Refer to "AREA MARKER" on page 16 for details. Operation 1. Short-circuit EXTERNAL CONTROL (14th terminal) to GND (15th terminal) to activate the external control. 2. Under the MAKE system, controls each function by short-circuiting (short with GND of 15th terminal) or stable disconnection (terminal open) of the controlled terminal. 3. Under the TRIGGER (trigger contact) system, controls each function by Pulse Control, that is by instantaneously (approx. 1 second) short-circuiting (short with GND of 15th terminal) the controlled terminal. NOTES: • When using INPUT A (the 2nd pin) through INPUT F (7th terminal), only the terminal in use should be short-circuited, the others must be disconnected. • Under the TRIGGER system, multiple terminals cannot be short-circuited to GND (15th terminal). Be sure to short-circuit the single terminal to GND. 23
