HOW TO USE EXTERNAL CONTROL Ⅵ 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 . 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 . 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 10 9 15 5 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. 14 13 12 11 4 3 2 1 8 7 6 The Names and Functions of Terminals No. Names Functions Operations (OFF p[ ON) 1 TALLY Puts on the tally lamp.

(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. 18
