Admin User Menu Items (SL4M)
Block Write Len
This menu item selects the maximum number of bytes written to the
USR block within the RFID tag memory at one time.
The default is 8.
Tag Class
This menu item selects the class of the custom tag. Class 0+,
Class 1.19, Gen 2, and Class Zuma tags are read/write. Class 0
tags are read only. The default is Gen 2.
Read Tries
This menu item selects how many times the RFID encoder will try
each read command. The default is infinite, which causes the
encoder to try until the operation times out.
Write Tries
This menu item selects how many times the RFID encoder will try
each write command. The default is 9.
RFID Calibrate
This menu item causes the printer to run calibration for the current
RFID tags installed in the printer. After the calibration is complete,
the custom settings are changed to work with the tags installed.
These settings do not take effect until Custom Tag is set to Enable.
Tag Position
This menu item determines how far the RFID tag position of the
currently installed custom tags differs from the RFID tag position of
the standard Printronix tag. Printronix printers print at maximum
speed with RFID labels that have RFID tags in the standard
position. The default is 0.0 inches.
NOTE: The units display in inches or millimeters, depending on the
Units setting (in the MEDIA CONTROL menu).
