Description of AI1422E Reader System
Because the AI1422E Reader System combines a reader and radio frequency (RF) module
into a single unit, you must connect the following items to the system: the external DC
power, the customer input/output (I/O), the selected communications interfaces, and the
antenna. These interface connectors are located on the AI1422E Reader System front
panel as shown in
Figure 3 – 1 .

Antenna Interface
Attach the antenna cable directly to the antenna interface on the front panel of the AI1422E
Reader System. The antenna cable length depends on the installation.
Interface Selection Switch
The AI1422E Reader incorporates a communications interface selection switch, which
allows on-the-fly changes to the communications mode. This switch allows selecting the
reader’s receive communications interface. All communications interfaces are configured
for simultaneous transmit, but only the interface selected by the switch is active for
commands transmitted into the reader.
Main RS–232 Interface
The main RS–232 interface is a standard DE09 plug connector used with a host processor.
In real-time mode, tag IDs are read and passed on to the host processor.
