How to Use External Control 20 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). Control signals from the remote control of external equipment are sent out to the equipment through the RS485 OUT terminal. Karaoke component, etc. RS-485 OUT Remote control Set the following items in "REMOTE SYSTEM" according to the external control terminal and control system you use (see page 15).

Any *1For 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. You can control the monitor by external control equipment*3. See also page 22. *3External control equipment is not commercially available. Consult your dealer if you need a dedicated controller. You can control the monitor from PC in your Local Area Network (LAN) through the web browser. LAN PC Hub PC Hub 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.
