HOW TO USE EXTERNAL

CONTROL

ABOUT EXTERNAL CONTROL

This monitor is provided with an external control terminal. MAKE (make contact) or TRIG. (trigger) system can be selected by the setting of REMOTE SYSTEM in the <SET-UP MENU>.

MAKE (make contact system) : The functino is controlled by short-circuiting or disconnecting each control terminal with pin 15

	(GND).
TRG. (trigger system)	: The function is controlled by short-circuiting with pulses (for about 1 second) (short-circuit/open
	with the 15th pin GND).

*The 14th pin (REMOTE ENABLE) is controlled with MAKE even though TRG. is selected.

*The 1st pin (TALLY) is always controlled by the make contact system regardless of the setting (ON/OFF) of the 14th pin (REMOTE ENABLE) or the REMOTE SYSTEM setting (MAKE, TRG.) in <SET-UP MENU>.

Note:

●When this monitor is externally controlled, the following buttons are disabled. MAKE: INPUT-A to D, UNDER SCAN, COLOR OFF, ASPECT on the front panel.

Connections

Connect (short-circuit) the 15th terminal (GND) to each of the 1st through 14th terminals in the 3-lines 15-pins D-sub connector. The functions of each terminal are listed below.

*1 : OFF stands for disconnection, and ON stands for short-circuit.

*2 : When INPUT REMOTE in the <SET-UP MENU> is set to A/B, OFF means “select INPUT A” and ON means “select INPUT B”.

*3 : When INPUT REMOTE in the set-up menu is set to A/B, pins not used should not be connected.

*4 : Do not connect.

*5 : Setting REMOTE ENABLE to ON enables external control from each terminal. (Only TALLY can be externally controlled all the time.)

*6 : INPUT REMOTE setting in the set-up menu (REMOTE SYSTEM shown only when MAKE is selected.)

For the D-sub pins 2, 3, 4 and 5, 4-pin or 1-pin control can be set with INPUT REMOTE in the set-up menu.

•4-pin control: Switches input by short-circuiting a specified signal line in INPUT A to D.

•1-pin control: Switches between INPUT-A and INPUT-B only with the 2nd pin of the D-sub connector. In this case, INPUT-C and INPUT-D cannot be selected.

OFF: INPUT A

ON : INPUT B

NOTES :

*When more than two terminals are selected (short-circuited) from INPUT A through INPUT D under the MAKE system, the signal input is prioritized alphabetically (A, B, C, D).

*To control INPUT A through INPUT D under the MAKE system, we recommend using the interlock switch, which turns off a switch when another switch is turned on.

To control INPUT A through INPUT D under the TRG. system, we recommend using the return switch, which stays ON while pressed.
