^RT – Read Tag (continued)
Example: This reads a block from a tag, and prints it on a label:
^XA
^FO20,120^A0N,60^FN1^FS
^FO20,100^A0N,20^FN2^FS
^RT1,0,7,3,0,5,0,0^FS
^RT2,0,2,2,0,5,0,0^FS
^XZ
The first ^RT command automatically detects the tag type, starting at block 7, reads three blocks of data in ASCII format. It will retry the command 5 times if necessary. A “void” label will be generated if the read is unsuccessful after ‘r’ retries. The data read will go into the ^FN1 location of the recalled format.
The second ^RT command automatically detects the tag type, string at block 2, reads two blocks of data in ASCII format. It retries up to 5 times. The data read will go into the ^FN2 location of the recalled format.
The data can be sent back to the host via the ^HV command.
