AXIS 240Q Blade - Rack Solution Installation Guide

The I/O Terminal Block

The AXIS 240Q Blade Video Server connects 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 240Q Blade supports several Pan/Tilt device drivers, which 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 con-

trolling 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

maximum voltage of 24V DC, this out-

put has an open-collector NPN transis-

tor with the emitter connected to GND.

To use with an external relay, a diode

must be connected in parallel with the

load, for protection against 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.
