5.8 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:
INPUT | V

| Min. | V

.
Open 0 V 2 V 0 mA
Closed 4.5 V 30 V 10 mA
The active state of these inputs are selected in software.
An anti-disturbance filter (debounce filter) is implemented in software on both inputs and is
software programmable to filter in the range from 500 microseconds to 10 milliseconds.
Refer to 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.
