External Control

7About the external control

This monitor has three external control terminals.

•MAKE/TRIGGER terminal (RJ-45): The following external control systems are available.

(1)MAKE (make contact) system: Controls the monitor by short-circuiting the corresponding pin terminal to the GND pin terminal, or disconnecting (opening) it (☞ below).

(2)TRIGGER (trigger) system: Controls the monitor by sending the pulse signal instantaneously to the corresponding pin terminal (☞ below).

•RS-232C terminal (D-sub 9-pin): Controls the monitor with the RS-232C system. (☞ “Using the serial communication” on page 15)

•RS-485 terminals (RJ-45): Controls the monitor with the RS-485 system. (☞ “Using the serial communication” on page 15)

Set the following items of “REMOTE SETTING” in SET-UP MENU according to the external control terminal and control system (☞ page 13).

Control terminal	Control system		“SERIAL TYPE” setting	“PARALLEL TYPE” setting
MAKE/TRIGGER	MAKE		—	MAKE
terminal
	TRIGGER		—	TRIGGER
RS-485 terminal	Serial	RS-485	RS485*1	—
RS-232C terminal	communication	RS-232C	RS232C*1	—

*1 On the monitor connected to the personal computer etc, select the terminal the equipment is actually connected to. On other monitors, select “RS485.”

•Control priority is as follows.

MAKE > TRIGGER, serial communication, and buttons and menu on the monitor

•You can use the external control even when “CONTROL LOCK” is set to “ON” (☞ page 13).

•When the monitor is off (on standby), external control is not available.

You can control the monitor by a personal computer or dedicated controller*2. For the details, see below.

*2 The controller is not commercially available. Consult your dealer if you need it.

7Using the MAKE/TRIGGER system

The MAKE/TRIGGER terminal is configured as follows. You can assign a function to each pin terminal in “REMOTE SETTING” (☞ “PIN1, PIN2, PIN3, PIN4, PIN5” on page 13).

• You cannot change the functions assigned to the pin terminals from 6th to 8th.

	Pin No.	Pin name	Pin No.	Pin name
This is a female	1	PIN1	5	PIN5
terminal.	2	PIN2	6	PIN6 (TALLY)*3
	3	PIN3	7	PIN7 (ENABLE)*4
	4	PIN4	8	PIN8 (GND)

To assign the functions to the pin terminals

For the operation procedure, see page 7.

1Select “REMOTE SETTING” on the SET-UP MENU.

2Set “PARALLEL TYPE” to “SET.”

3Select a pin name (“PIN1” – “PIN5”) for which you want to assign a function, then select the function you want to assign.

• For selectable functions, see the tables below.

*5 While controlling with the MAKE system, the screen is switched between normal screen (opening) and blue screen (short-circuiting). While controlling with the TRIGGER system, the screen changes as same as when pressing SCREENS CHECK button (☞ page 6).

*6 Must be controlled with the TRIGGER system. This function cannot be controlled with the MAKE system. *7 Selects which functions in “AREA MARKER” are activated, non-“R-” items or “R-” items (☞ page 10).

*8 While controlling with the MAKE system, the level meter is switched between displayed (short-circuiting) and hidden (opening). When “LEVEL METER ch” is set to “OFF,” the level meter is not displayed (“NO EFFECT” appears). While controlling with the TRIGGER system, the pattern of the audio channel display is switched.

*9 Displays the information shown when INPUT SELECT button of the current input is pressed (☞ “About the Status Display” on page 7). While controlling with the MAKE system, the information is displayed only at the moment of short- circuiting.

•You cannot assign the same function to different pin terminals.

•The TRIGGER system switches each function by short-circuiting the pin terminal for about 1 second and opening it.

*3 The 6th pin terminal controls turning on or off the tally lamp (available to control even when the 7th pin terminal is invalid).

*4 The 7th pin terminal makes the external control valid/invalid. Make sure to control the terminal by the MAKE system.
