AXIS 2460 User’s Manual Unit Connectors 65

The I/O Terminal Block Connector

Typically used in association with programming scripts for developing applications for event triggering, alarm notification via e-mail, etc., the 16-pin I/O Terminal Block is located on the rear panel and provides the interface to: a single relay switch output, four digital photo-coupled inputs, and an RS-485 interface. See page 67 for more information about RS-485.

This section describes the pinout, interface support and the control and monitoring functions provided by this connector.

Connector Pinout

The pinout for the Terminal Block (illustrated above) and signaling details for each pin is fully described in the table below:

Pin Function Description

2Not connected.

3Digital Input 3 - Photocoupler Anode (+) Photocoupled Input 3: Electrically isolated from the chassis and connec-

4	Digital Input 3 - Photocoupler Cathode (-)	tors, this input can be supplied from an external DC voltage or the DC
		Power Input/Output on pins 9 and 10. Driven by 5-24V.
5	Digital Input 4 - Photocoupler Anode (+)	Photocoupled Input 4. As above.
6	Digital Input 4 - Photocoupler Cathode (-)
7	RS-485 - B (inverting)	Serial Port 1- RS-485. A half-duplex RS-485 interface for controlling
8	RS-485 - A (non-inverting)	auxiliary equipment. Note: Serial Port 1 is programmed as either
		RS-232 (COM1 Connector) or RS-485 (Terminal Block Connector), via
		the browser interface.
9	DC + Power Output 12V	This can drive the photocoupler inputs or other equipment; such as an
10	DC - Power Output	IR-sensor. A maximum current of 50mA can be sourced from the DC
		output. Pin 10 is connected to the unit chassis and to Ground on each
		serial port and video input. See the schematic diagram on page 68.
11	Digital Input 1 - Photocoupler Anode (+)	Input 1 Photocoupler input. As for Input 3.
12	Digital Input 1 - Photocoupler Cathode (-)
13	Digital Input 2 - Photocoupler Anode (+)	Input 2 Photocoupler input. As for Input 3.
14	Digital Input 2 - Photocoupler Cathode (-)
15	Relay Switch	Relay switch - electrically isolated from chassis and connectors.
16	Relay Switch
