5.4 DIGITAL OUTPUTS
Activation Event
Defines the event activating the output.
Selections:
Disabled : the output is always in the selected idle state.
Good Read : the event occurs if the code is read.
No Read : the event occurs if no code is read.
Wrong Code : the event occurs if a code is successfully decoded but does not match the
Verifier Code.
Deactivation Event
Defines the event deactivating the output.
Selections:
Timeout : the output deactivation event occurs after the deactivation timeout expires.
Reading Phase Active : the output deactivation event occurs, when a start reading phase
event takes place.
Disabled : No deactivation event occurs.
Deactivation Timeout
When the Deactivation Event is Timeout, this indicates the maximum duration of the output
pulse.
Active Level
Determines the active state of the output.
Each output can be represented as an NPN transistor; this transistor acts like a switch: so,
when the transistor is OFF, it acts like an OPEN switch. On the contrary, when the transistor
is ON, it acts like a CLOSED switch.
Selections:
Active Closed : the idle state of the output line is open, that is, the NPN transistor is OFF
(like an open switch). When the output is activated, the transistor goes ON (like a closed
switch).
Active Open : the idle state of the output line is closed, that is, the NPN transistor is ON (like
a closed switch). When the output is activated, the transistor goes OFF (like an open switch).
