Command Codes

This chapter discusses the host-transmitted commands that are used to control the AI1422E Reader
configuration and operation.

The AI1422E Reader is delivered from the factory with specified default settings that
determine how the reader operates. Commands transmitted by the host computer can
change the default settings and control additional features. The commands can be
transmitted by manually entering the commands at the host keyboard if the host is in
terminal emulation mode.

Note: If you are using Wiegand mode, you must connect the PC or laptop to the
AI1422E Reader using the RS–232 or RS–422 interface and a terminal emulation
program to send commands to the reader. You can leave the Wiegand interface
connected during this procedure.

Operating Modes

The AI1422E Reader has three modes of operation: data mode, command mode, and
download mode. The software for the AI1422E Reader contains two separate programs —
boot and application. The boot program has control of the AI1422E Reader on startup and
when operating in download mode. The application program has control of the AI1422E
Reader during data mode and command mode operation and holds the application code.
Together, they control the AI1422E Reader in the three modes of operation.

Data Mode

The AI1422E Reader is in the data mode upon power-up. While in the data mode, the
AI1422E Reader sends all communications as data messages, such as tag IDs and reports,
to the host computer. Reports provide information on input status changes (input0 and
input1), a presence without tag report, and buffer overflow information. The host computer
can send only two commands to the AI1422E Reader while in data mode:

•

Command

!01 Switch To Command Mode

changes the AI1422E Reader from the

data mode to the command mode. Refer to

“01/~~CC Switch to Command Mode” on

page 7-4

Note: The AI1422E Reader transmits ID codes to the host computer when the
AI1422E Reader is in data mode. If the AI1422E Reader remains in the command
mode with tags passing through the read zone, all tag IDs are not reported.

Command Mode

While the AI1422E Reader is in the command mode, the host computer sends commands
to the AI1422E Reader that can be used to control the operation and configuration of the
reader. After the AI1422E Reader receives a command, it transmits a command response
message. Typically, the command message contains

Error, Done,

or data relating

specifically to the command request. These messages may be of variable length since
some commands require information as part of the message.
