20 External Control
7 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 22)
• RS-232C terminal (D-sub 9-pin): Controls the monitor with the RS-232C system. ( ☞ “Using the serial
communication” on page 22)
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 18)

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 19).
• 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 23).

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

7 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 18)
• 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
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 7.
1 Select “REMOTE SETTING” on the SET-UP MENU.
2 Set “PARALLEL TYPE” to “SET.”
3 Select 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 21.
Operation of the external control
1 Set “PARALLEL TYPE” of “REMOTE SETTING” to “MAKE” or “TRIGGER” in the SET-UP MENU.
2 Short-circuit the 7th pin terminal (ENABLE) to the 8th pin terminal (GND) so that the monitor can be controlled
by the external control.
3 When 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.
This is a female terminal.
