where:
i indicates ‘I’ string output
VVVV is the application firmware version number;
WWWW is the core application firmware version number;
XXXX is reserved;
SSSSSSSSSS is the Reader’s serial number (ten digits);
A is the current execution state:
“A” means core is running
OO is the OEM identifier;
D is the display type:
“0” is no display device.
YYYY is reserved;
HH is the hardware revision;
IIII is the hardware type identifier (value in register 21B);
JJJJ is the boot application version;
KKKK is the operating system kernel version;
LLLL is the root file-system version;
<TAB> is the ASCII TAB character;
Z…Z is the OEM decoder version: a null terminated string of printable ASCII characters.
Message response; data contains a message (comment). ‘m’ packets are not sent when the
Reader is in “raw” mode.
Read barcode failure; decoder attempted but failed to read a barcode.
Decoded data from a barcode; data contains the data decoded from the barcode.
In “raw” mode (as opposed to “packet” mode), type m packets are not sent, only the decoded data is
sent for type z packets, and all other packets are sent without the packet-start and crc16 fields. In
“packet-mode,” the packet-start and crc16 fields are always sent. (See Figure 1)
