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 terminal (RJ-45): Controls the monitor with the RS-485 
system (→ “Using the serial communication” on page 28).
 RS-232C terminal (D-sub 9-pin): Controls the monitor with the RS-
232C system (→ “Using the serial communication” on page 28).
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 24).

  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 25)
 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 29)

 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 24)
 You cannot change the functions assigned to the pin terminals 
from 6th to 8th.
 
This is a female 
terminal.

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

  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 18.
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 29.
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.
