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 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 (
"SERIAL TYPE," "PARALLEL TYPE" on page 20).

* 1 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." (
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)
<MAKE/TRIGGER system>
You can control the monitor by a personal computer or dedicated
controller * 2 .

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 20)
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
TYPE" 1
(available to control even when the 7th pin terminal is invalid).
* 2 The 7th pin terminal makes the external control valid/invalid. Make
MAKE
sure to control the terminal by the MAKE system.
To assign the functions to the pin terminals
—
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.
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.
