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” below
●
RS-485 terminals
(RJ-45): Controls the monitor with the RS-485
system (
☞
“Using the serial communication” on page 23).
●
RS-232C terminal
(D-sub 9-pin): Controls the monitor with the
RS-232C system (
☞
“Using the serial communication” on page 23).
Set the following items of “Remote Setting” in Set-Up Menu

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
“Volume Lock” or “All Lock” (
☞
page 19).
●
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 24).

External Control
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 18).
●
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.
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 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, activate the pin you
want after deactivating the currently used pin.
●
When selecting the “Trigger” system, you can operate only one
function at a time. Operate the functions one by one.
