^RT
Read RFID Tag
Description This command tells the printer to read the current RFID tag data. The data can
be sent back to the host via the
^HV command.
Format ^RT#,b,n,f,r,m,s
The following table identifies the parameters for this format.
Note • It is recommended that you use the ^RF , ^RM , and ^RR commands rather than the
^RT command. The ^RT command is provided only for backward-compatibility with label
formats that were developed for other Zebra RFID printers.
Parameters Details
# = number to be
assigned to the field
Accepted values: 0 to 9999
Default value: 0
b = starting block number Accepted values: 0 to n, where n is the maximum number of blocks for the tag.
Default value: 0
n = number of blocks
to read*
Accepted values: 1 to n, where n is the maximum number of blocks for the tag
type minus the starting block number. For example, if the tag has 8 blocks
(starting with block 0) and you start with block 6, n can be 2. This would return
block 6 and block 7 information.

Default value: 0
r = number of retries Changes the number of times that the printer attempts to read a particular block
of a single RFID tag. (Same retry rules as the
^RR command.)
Accepted values: 0 to 10
Default value: 0
m = motion Enables or disables RFID motion for the current field.
Accepted values:
• 0 (Feed label after writing.)
