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).

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).

Using the MAKE/TRIGGER system
The MAKE/TRIGGER terminal is confi gured 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.

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.
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 19.
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.
