<IR OUT system>
Control signals from the remote control of external equipment are sent out to the equipment through the RS-
485 OUT terminal. Consult your dealer for details.
• You cannot use the IR OUT system and the serial communication via the RS-485 terminal at the same time.

About the external control

This monitor has the following external control terminals:
• RS-232C terminal: Controls the monitor by external control equipment (a personal computer or a dedicated
controller) (see “Using the serial communication” on page 21).
• 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 page 21).
(2) IR OUT system: Controls other equipment through the monitor by using the remote control supplied
with the equipment.
(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 page 22).
(4) TRIG. (trigger system): Controls the function by inputting the pulse signal instantaneously to the
corresponding pin terminal (see page 22).
• LAN terminal (10BASE-T): Controls the monitor from a PC in the network through the web browser (see
“Using the LAN system” on page 23).
Set the following items in “REMOTE SYSTEM” according to the external control terminal and control system
you use (see page 15).

*1 For the monitor connected to the external control equipment, set “REMOTE IN SEL.” according to the actual
connection. Set other monitors to “RJ-45.”
*2 Set “NETWORK SETTING” in the set-up menu (see pages 16 and 23).
NOTE
• The functions controlled by an external device through the MAKE connection cannot be controlled on the
main unit or the remote control.
• While the Control Lock (see page 16) is in use, you can use external control.
<Serial communication>
Several monitors can be controlled by connecting their RS-485 IN and OUT terminals. See also page 21.
Do not use the AC OUT terminal on the monitor for power supply to another monitor.
