MATRIX 410™ REFERENCE MANUAL

4.5 INPUTS

There are two optocoupled polarity insensitive inputs available on the reader: Input 1

(External Trigger) and Input 2, a generic input:

The External Trigger can be used in One Shot Mode or in Phase Mode. Its main functions

are:

acquisition trigger in One Shot Mode

reading phase-ON/reading phase-OFF command in Phase Mode

The main functions of the general purpose Input 2 are:

second external trigger in Phase Mode

match code storage command when the Match Code option is enabled

The electrical features of both inputs are:

= 30 Vdc max.

= 10 mA (reader) + 12 mA (CBX) max.

The active state of these inputs are selected in software. Refer to the VisiSet™ Help On

Line.

An anti-disturbance filter is implemented in software on both inputs so that the minimum

pulse duration is 0.5 milliseconds. This value can be increased through the software

parameter Debounce Filter, see the Digital I/O folder in the VisiSet™ Help On Line for further

details.

These inputs are optocoupled and can be driven by both NPN and PNP type commands.

NOTE

Polarity insensitive inputs assure full functionality even if pins A and B are

exchanged.

The connections are indicated in the following diagrams:
