^RR

Use this command to change the number of times that the printer attempts to read or write to a particular block of a single RFID tag (Not applicable to printers with firmware V75.19.7Z or later.) or to enable the adaptive antenna element selection feature.

Specify RFID Retries for a Block or Enable Adaptive Antenna Selection

This command’s function is different than the “number of labels” parameter in the
^RS
command.
This command is persistent and will be used in subsequent formats if not provided.
Format:
^RRn,a
Parameters
Details
n
= number of retries
This parameter does not apply to Link-OS printers.
Values:
0
to
10
Default:
6
a
= adaptive antenna element selection
  • This parameter is valid only on ZT400 and ZT600 Series RFID printers.
  • This parameter is valid only on R110Xi4, ZT400 Series, and ZT600 Series RFID printers.
  • The label length must be 2 in. (51 mm) or longer.
  • Activating this feature may slow throughput on damaged or weak RFID tags.
If the printer cannot find RFID tags with the antenna element specified during the number of retries specified (if applicable), the printer may try neighboring antenna elements. If the printer is unsuccessful communicating with the RFID tag after trying the neighboring antenna elements, the printer voids the label.
Values:
0
= None. The printer uses only the current antenna element selection.
1
= Neighbors. The printer attempts to read the tag using the antenna elements to the left/right and above/below the current antenna element. The antenna element that is successful is used for all subsequent RFID commands until the next unsuccessful attempt.
Default:
0
Example:
This example sets the adaptive antenna element selection to
1
(Neighbors).
^XA ^RR,1 ^XZ
Example:
This example sets the read block retries to 5.
^XA ^FN1^RR5^RFR,H^FS ^HV1^FS ^XZ
Example:
This example sets the write block retries to 2.
^XA ^RR2^RFW,H^FD1234^FS ^XZ
Example:
On an R110Xi4 printer, this example sets the write retries to 2 and allows the printer to try neighboring antennas in the event that the current antenna cannot write to the RFID tag.
