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 24).

●

 RS-232C terminal (D-sub 9-pin): Controls the monitor with the RS-

232C system (☞ “Using the serial communication” on page 24).

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

  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 20)

●

 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 25)

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 20)

 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).

  The 7th pin terminal makes the external control valid/invalid. Make 

sure to control the terminal by the MAKE system.

For the operation procedure, see page 13.

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 23.

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.

 

 

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.
