25-PIN CABLE ELECTRICAL CONNECTIONS

5.6 INPUTS

There are two optocoupled polarity insensitive inputs available on the 25-pin connector of 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:

Maximum voltage: 30 Vdc

Maximum current: 12 mA

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:

Pin Name Function

9 Vdc Power Supply input voltage +

18 I1A External Trigger A (polarity insensitive)

19 I1B External Trigger B (polarity insensitive)

7 GND Power Supply input voltage -

The yellow Trigger LED (

Figure 16, 5) is on when the active state of the External Trigger

corresponds to ON.
