HOW TO USE EXTERNAL
CONTROL
Ⅵ ABOUT EXTERNAL CONTROL
This monitor is provided with an external control terminal. MAKE (make contact) or TRG. (trigger) system can be selected.
(MAKE (make contact system): The function is controlled with H and L (short-circuit/open with the 15th pin 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.
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.
*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, H: INPUT A and L: INPUT B are set.
*3: When INPUT REMOTE in the set-up menu is set to A/B, pins not used should not be connected.
*4: When INPUT REMOTE in the set-up menu is set to A/B, pins not used should not be connected.
*5: When INPUT REMOTE in the set-up menu is set to A/B, pins not used should not be connected.
*6: Do not connect.
*7: Setting REMOTE ENABLE to ON enables remote control from the REMOTE terminal.
*8: 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.
Open (H): INPUT-A
Short-circuit (L): INPUT-B
NOTE : When more than two terminals are selected (short-circuited) from INPUT A through INPUT D, signal input is prioritized
alphabetically (A, B, C, D).
To control INPUT A through INPUT D, we recommend using the interlock switch, which turns off a switch when another
switch is turned on.
