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:
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, by default, is implemented in software on both inputs. The value
can be changed through the software parameter Debounce Filter. See the Help On Line
page of the Reading Phase step (Inputs) in DL.CODE for further details on these
parameters.
These inputs are optocoupled and can be driven by both NPN and PNP type commands.
