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
1 Not connected.
2 Not connected.
3 Digital Input 3 - Photocoupler Anode (+) Photocoupled Input 3: Electrically isolated from the chassis and connec-
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.
4 Digital Input 3 - Photocoupler Cathode (-)
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
auxiliary equipment.
Note: Serial Port 1 is programmed as either
RS-232 (COM1 Connector) or RS-485 (Terminal Block Connector), via
the browser interface.
8 RS-485 - A (non-inverting)
9 DC + Power Output 12V This can drive the photocoupler inputs or other equipment; such as an
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.
10 DC - Power Output
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
