AXIS 207/207W - The I/O Terminal Connector 37

The I/O Terminal Connector

Pinout and Interface

The 4-pin I/O terminal connector provides the interface to:

1 transistor output

1 digital input

auxiliary power and GND

The terminal connector is used in applications for e.g. motion detection, event triggering, time lapse recording, alarm notification via email, image storage to FTP locations, etc.

Input - for connecting e.g. a pushbutton. If the pushbutton is pressed, the state changes and the input becomes active (shown under Event Configuration > Port Status).

Output - connects e.g. an alarm device that can be activated by Output buttons on the Live View page, or by an Event Type. The output will show as active (Event Configuration > Port Status) if the alarm device is activated.

Electrically connected in parallel with the

 

 

 

 

 

 

 

 

connector for the PS-L/PS-H power adapter,

 

 

 

 

this pin provides an auxiliary connector for

 

 

 

 

mains power to the unit. This pin can also

 

 

 

 

be used to power auxiliary equipment, max

 

 

 

 

50mA.
