•External I/O cable
IMPORTANT:
•Off, input, and output of the external I/O terminal 2 and 3 can be switched by configuring the setting. The default of EXT I/O terminal 2 and 3 is “Off”. It is possi- ble 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 alarm 2” or “Terminal alarm 3” on the [Alarm] tab on the “Alarm” page. Refer to the Operating Instructions on the provided
•When using the EXT I/O terminals as the output termi- nals, ensure they do not cause signal collision with external signals.

•ALARM IN1/ BLACK/WHITE IN, ALARM IN2, ALARM
IN3
Input specification:
OFF: Open or 4 V - 5 V DC
ON: Make contact with GND (required drive current:
1mA or more)
•ALARM OUT, AUX OUT
Output specification: Open collector output (maxi- mum applied voltage: 20 V DC)
Open: 4 V - 5 V DC by internal
Close: Output voltage 1 V DC or less (maximum drive current: 50 mA)
•Microphone/line input cable
Connect a monaural mini plug (ø3.5 mm).
•Input impedance: Approx. 2 kΩ (unbalanced)
•Recommended cable length:
Less than 1 m {3.28 feet} (for microphone input) Less than 10 m {32.8 feet} (for line input)
•Recommended microphone:
(option)
•Supply voltage: 2.5 V ±0.5 V
•Recommended sensitivity of microphone:
•Input level for the line input: Approx.
IMPORTANT:
•Connect/disconnect the audio cables and turn on the power of the camera after turning off the power of the audio output devices. Otherwise, loud noise may be heard from the speaker.
•Audio output cable
Connect a stereo mini plug (ø3.5 mm). (Audio output is monaural.) Use an external speaker with amplifier.
•Output impedance: Approx. 600 Ω (unbalanced)
•Recommended cable length: Less than 10 m {32.8 feet}
•Output level:
Note:
•Make sure that the stereo mini plug is connected to this cable. When a monaural mini plug is connected, audio may not be heard.
When connecting a monaural speaker with amplifier, use an optional conversion cable
