After the cable connection, connect the exter-
nal I/O terminal plug to the external I/O termi-
nals of the camera.
IMPORTANT:
• Do not connect 2 wires or more directly to a terminal. When it is necessary to connect 2 wires
or more, use a splitter.
• Input and output of the EXT I/O terminal 2 and 3 can be switched by configuring the setting.
"Off" is selected by default. It is possible to determine whether or not to receive input from EXT
I/O terminal 2 and 3 (ALARM IN2, 3) by selecting "Off", "Alarm input", "Alarm output" or "AUX
output" for "Terminal 2" or "Terminal 3" on the [Alarm] tab on the "Alarm" page. Refer to the
Operating Instructions (included in the CD-ROM) for further information.
• Connect an external device with verifying that the ratings are within the specifications below.
• When using the EXT I/O terminals as the output terminals, ensure they do not cause signal col
-
lision with external signals.
