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.

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).

• 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.
Pin No.
This is a female terminal.
The 6th pin terminal controls turning on or off the tally lamp
*1
(available to control even when the 7th pin terminal is invalid).
The 7th pin terminal makes the external control valid/invalid. Make
*2
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.
