Reader Mode Control — Command Group 0
Group 0 commands control reader mode. The mode determines whether the reader is
transmitting data to or receiving data from a host computer or terminal.
00/662 Switch to Data Mode (Factory Default)
Command !00
switches the reader to data mode, which allows the reader to transmit tag
data (ID codes) to the host. In addition to switching the reader to data mode, command !00
automatically saves to non-volatile memory (NVRAM) any user parameters that had been
changed during the command mode session. The reader enters data mode on power up.
The command
!662
is present for backward compatibility with previous generation
AI1422 readers, and is not recommended for use.
Caution
To save user parameter changes to NVRAM, you must send command !00/!662
before powering down the reader.
While operating in data mode, the reader accepts the following commands:
• Command

01/~~CC Switch to Command Mode
