AXIS 241Q/241S - Unit Connectors 49

The I/O Terminal Connector

This section describes the pinout and interface support provided by the 12-pin I/O terminal connector, which includes:

4 digital transistor outputs

4 digital inputs

an RS-485 interface

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.

Inputs - e.g. a push button. If the button is pressed, the state changes, and the input will be active (shown under Event Configuration > Port Status).

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

The AXIS 241Q/241S includes one (green) 12-pin connector block. Connect input/output devices to this block:

1.Loosen the corresponding screw on top of the pin on the connector block (see the table above to determine which pin to use).

2.Push the cable into the connector block and secure it by fastening the screw.

3.Once all devices are connected, connect the connector block to the video server’s terminal connector.
