AXIS 241Q/S Blade - Rack Solution Installation Guide

The I/O Terminal Block

Axis Blade Video Servers connect to an I/O terminal block used for transmitting data over multi-drop

communication lines:

• RS-485 Pan/Tilt devices

• RS-232 Pan/Tilt devices

• External triggering (typically associated with CCTV equipment)

The Axis Blade Video Servers support several Pan/Tilt device drivers that are available from the Axis Web site

at www.axis.com

Pin Function Description Pin Function Description

1 RS-232 RI 15 RS-485 - A

(non-inverting)

A half-duplex RS-485 interface for controlling

auxiliary equipment, e g. PTZ devices

2 RS-232 CTS 16 RS-485 - B

(inverting)

3 RS-232 RTS 17 Transistor Output 4 With a maximum load of 100mA and maxi-

mum voltage of 24V DC, this output has an

open-collector NPN transistor with the emit-

ter connected to GND. If it is to be used with

an external relay, a diode must be connected

in parallel with the load for protection against

any voltage transients

4 RS-232 DSR 18 GND

5 GND 19 Transistor Output 3 See Transistor Output 4 (above)

6 RS-232 DTR 20 Transistor Output 2 See Transistor Output 4 (above)

7 RS-232 TXD 21 GND

8 RS-232 RXD 22 Transistor Output 1 See Transistor Output 4 (above)

9 RS-232 CD 23 Digital Input 4 Connect to GND to activate or leave floating

(or unconnected) to deactivate

10 GND 24 GND

11 n/a 25 Digital Input 3 See Digital Input 4 (above)

12 n/a 26 Digital Input 2 See Digital Input 4 (above)

13 n/a 27 GND

14 n/a 28 Digital Input 1 See Digital Input 4 (above)
