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.
*
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

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.
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.
