External Control

„About 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.

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

☞“Using the MAKE/TRIGGER system” on the right

•RS-485 terminals (RJ-45): Controls the monitor with the RS-485 system (☞ “Using the serial communication” on page 20).

•RS-232C terminal (D-sub 9-pin): Controls the monitor with the RS- 232C system (☞ “Using the serial communication” on page 20).

Set the following items of “REMOTE SETTING” in SET-UP MENU according to the external control terminal and control system

(☞ “SERIAL TYPE,” “PARALLEL TYPE” on page 16).

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

Control priority is as follows.

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

•You can use external control even when “CONTROL LOCK” is set to “VOL.LOCK” or “ALL LOCK” (☞ page 17).

•When the monitor is off (on standby), external control is not available. But certain external controls (starting/terminating communication, turning on the monitor) are available through the serial communication (☞ page 21).

<MAKE/TRIGGER system>

You can control the monitor by a personal computer or dedicated controller*2.

•“Using the MAKE/TRIGGER system” on the right.

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

„Using 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” in “PARALLEL TYPE” on page 16).

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

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

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

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

To assign the functions to the pin terminals

For the operation procedure, see page 12.

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 the selectable functions, see the table on page 19.

Operation of the external control

1Set “PARALLEL TYPE” of “REMOTE SETTING” to “MAKE” or “TRIGGER” in the SET-UP MENU.

2Short-circuit the 7th pin terminal (ENABLE) to the 8th pin terminal (GND) so that the monitor can be controlled by the external control.

3When the “MAKE” system is selected: Operate each function by short-circuiting the corresponding pin terminal to the 8th pin terminal (GND) or opening it.

When the “TRIGGER” system is selected: Operate each function by pulse control, that is short-circuiting the corresponding pin terminal to the 8th pin terminal (GND) for about 1 second and opening it.

•When changing the input with MAKE system, only one pin terminal must be short-circuited. (Other pin terminals must be opened.)

•When selecting the “TRIGGER” system, you can operate only one function at a time. Operate the functions one by one.
