Description of AI1422 Reader System
Because the AI1422 Half-Frame Reader System combines a reader and radio fre-
quency (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 main and auxil-
iary RS–232 interfaces, and the antenna. These interface connectors are located on the
AI1422 Half-Frame Reader System front panel as shown in Figure 3-1.

Main RS–232 Interface
The main RS–232 interface is a standard DB25 plug connector used with a host pro-
cessor. During operation, a host processor system uses the reader system functions in
real-time operating mode. In real-time mode, tag IDs are read and passed on to the
host processor. Figure 3-2 illustrates the RS–232, DB25 plug connector pin-outs.
