CBX Electrical Connections
For applications that do not use RS422 transmission to the reader (terminal block RX+
and RX- signals), do not leave these lines floating but connect them to SGND as
shown below.
NOTE

Inputs

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
CAUTION
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
AB
I
IN
The active state of these inputs are selected in software.
