AXIS 243Q Blade - I/O Terminal connector 50

I/O Terminal connector

The inputs and outputs on the AXIS 243Q Blade are accessed via the 12-pin I/O terminal connector on the AXIS 291 1U Video Server Rack. The following are available:

•4 digital transistor outputs (1 per video input)

•4 digital inputs (1 per video input)

•RS-485 interface (AXIS 243Q(1) Blade only)

•auxiliary power and GND

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

•Inputs - used for a push button, for example. If the button is pressed, the state changes, and the input is active (shown under Event Configuration > Port Sta- tus).

•Outputs - 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 shows as active (in Event Configuration > Port Status), if the device is activated.

Description

 

 

 

1

+12V DC Power output

This pin can be used to power auxiliary equipment, 12V DC max 100mA per

 

 

blade.

 

 

 

2

GND

Ground

 

 

 

3

Input 1 (Video input 1)

Connect to GND to activate or leave floating (or unconnected) to deactivate.

 

 

 

4

Input 2 (Video input 2)

 

 

 

 

5

Input 3 (Video input 3)

 

 

 

 

6

Input 4 (Video input 4)

 

 

 

 

7

Output 1 (Video input 1)

With a maximum load of 100mA and maximum voltage of 24V DC, the output

 

 

has an open-collector NPN transistor with the emitter connected to pin 2

8

Output 2 (Video input 2)

 

 

(GND). If it is to be used with an external relay, a diode must be connected in

9

Output 3 (Video input 3)

parallel with the load for protection against any voltage transients.

 

 

10

Output 4 (Video input 4)

 

 

 

 

11

RS-485-A

A half-duplex RS-485 interface for controlling auxiliary equipment, e g. PTZ

 

(non-inverting)

devices.

 

 

 

12

RS-485-B (inverting)

 

 

 

 

The AXIS 291 Video Server rack includes a 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.
