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: 
 

V

AB

 = 30 Vdc max. 

I

IN

 = 10 mA (reader) + 12 mA (CBX) max. 

 
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. 
 

 
 
The connections are indicated in the following diagrams:
