CBX ELECTRICAL CONNECTIONS

4.4 INPUTS

CAUTION: When Inputs 1 and 2 are connected through the CBX
connection box, they become opto-isolated and polarity insensitive and
acquire the electrical characteristics listed below. To function correctly, they
require setting the Input Line Type configuration parameters to NPN for the
respective input. The hardware connection to the CBX can be either NPN or
PNP.
There are two opto-isolated polarity insensitive inputs available when the reader is connected
to the CBX: 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 = 30 Vdc max.
AB
I = 12 mA (CAB-1011) + 12 mA (CBX) max.
IN
The active state of these inputs is 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.
NOTE: Polarity insensitive inputs assure full functionality even if pins A and
B are exchanged.
The connections are indicated in the following diagrams:

The yellow Trigger LED (Figure 15, 5) is on when the active state of the External Trigger
corresponds to ON.
