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 function is controlled by short-circuiting or disconnecting each control terminal with pin 15
(GND).
TRIG. (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 TRIG. is selected.
Note:
● When this monitor is externally controlled, the following buttons are disabled.
MAKE: INPUT-A and B, UNDER SCAN 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.
The Names and Functions of Terminals
No. Names Functions
1 not used –
2 INPUT A Changes the input to INPUT A
3 INPUT B Changes the input to INPUT B
4 not used –
5 not used –
6 not used –
7 not used –
8 not used –
9 not used –
10 ASPECT Changes the screen ratio to 16:9
11 UNDER SCAN Makes the screen under-scan
12 not used –
13 not used –
14 REMOTE ENABLE Makes the external control from the
REMOTE terminal valid or invalid
15 GND Used as a ground terminal
*1 : OFF stands for disconnection, and ON stands for short-circuit.
*2 : Do not connect.
*3 : Setting REMOTE ENABLE to ON enables remote control from the REMOTE terminal.
*4 : INPUT REMOTE setting in the set-up menu (REMOTE SYSTEM shown only when MAKE is selected.)
For the D-sub pins 2 and 3, 2-pin or 1-pin control can be set with INPUT REMOTE in the set-up menu.
• 2-pin control: Only the specified signal line in INPUT-A or B is short-circuited.
• 1-pin control: Switches between INPUT-A and INPUT-B only with the 2nd pin of the D-sub connector.
OFF : INPUT A
ON : INPUT B
NOTES :
● When both INPUT A and INPUT B are selected (short-circuited) under the MAKE system, INPUT A has priority.
● To control INPUT A and INPUT B in MAKE mode, we recommend using the interlock switch, which turns off a switch when
another switch is turned on.
To control INPUT A and INPUT B in TRG. mode, we recommend using the return switch, which stays ON while pressed.
