I/O Terminal Block

The 7-pin I/O terminal connector provides the interface to a

solid state relay output, two digital inputs, RS-485/422 and

GND.

The terminal connector is used in

applications for e.g. motion

detection, event triggering, time lapse recording, alarm

notification via email, image storage to FTP locations, etc.

• Input - Used for

connecting external alarm devices

and triggering images for specific alarm-based events.

The input is typically connected to a motion detector

or any other external security device, and images can

be uploaded whenever the detector is activated. Con-

nect to GND to activate.

• Output - This can

drive a maximum load of 50VDC or

35VAC at 100mA directly or heavier loads by connect-

ing additional relay circuitry

. If the output is used

with an external relay, a diode must be connected in

parallel with the load for protection against any volt-

age transients.

I/O terminal connector block pinout:

Pin Function Description

1 Output A On the external device output terminals (A and B), there is no distinction between positive and nega-

tive (+ and -). The terminals use a photocoupler and are

electrically isolated from the other internal

circuitry.

The maximum load should not exceed 100mA and the maximum voltage shoul

d be not more than

50VDC or 35VAC.

2 Output B

3 Digital Input 1 Connect to GND to activate, or leave float

ing (or unconnected) to deactivate.

4 Digital Input 2

5 RS-485/422-A

(non-inverting)

A half-duplex RS-485 interface for controll

ing auxiliary equipment.

6 RS-485/422-B

(inverting)

7 GND Ground.
