ZPL II Commands for RFID
R4Mplus User Guide 75
^RS
RFID Setup
Description The ^RS command is used to set up for RFID operation. Specifically, it moves
the tag into the effective area for reading or writing or for possible error handling if there is an
error.
Format ^RSt,p,v,n,e
Table 11 identifies the parameters for this format.
Note • Use care when using this command in combination with ^RT (reading tag
data) or ^RI (reading the tag’s unique ID number). Problems can occur if the data
read from the tag is going to be printed on the label. Any data read from the
transponder must be positioned to be printed above the read/write position. Failure to
do this will prevent read data from being printed on the label.
