7 About the external control
This monitor has two external control terminals as follows:
• RS-232C terminal: For operation using this terminal, consult your dealer.
• RS-485 terminals: You can select the external control system in “REMOTE SYSTEM” on the set-up menu (see “CNT. RJ45
OUT” and “CNT. RJ45 IN” on page 25).
(1) Serial communication: Controls the monitor by a personal computer or a dedicated controller (see page 32).
(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 page 33).
(4) TRIG. (trigger system): Controls the function by inputting the pulse signal instantaneously to the corresponding
pin terminal (see page 33).
Set the input/output terminals correctly according to the system you use (see “REMOTE SYSTEM” on page 25).
