About the external control
This monitor has two external control terminals as follows:
• RS-232C terminal:
Controls the monitor by external control equipment (a personal computer or a dedicated controller)
(see “Using the serial communication” on pages 34 and 35).
• RS-485 terminals: The following external control systems are available.
(1) Serial communication: Controls the monitor by external control equipment (a personal computer or a dedicated
controller) (see pages 34 and 35).
(2) IR OUT system: Controls other equipment by using the remote control supplied with this monitor.
(3) MAKE (make contact system): Controls the function by short-circuiting the corresponding pin terminal to the GND pin
terminal, or disconnecting (opening) it (see pages 36 and 37).
(4) TRIG. (trigger system): Controls the function by inputting the pulse signal instantaneously to the corresponding
pin terminal (see pages 36 and 37).
Set the following items in “REMOTE SYSTEM” according to the external control terminal and control system you use (see page

NOTE
• Control priority is as follows:

• While the Control Lock is in use, you can use external control.
Several monitors can be controlled by connecting their RS-485 IN and OUT terminals. See also pages 34 and 35.
Control signals from the remote control are sent to external equipment via the RS-485 OUT terminal.
