Disabling Write Protection When Using V680 Commands
Disabling ID Tag Write Protection for Part of the Area Being Used:
To temporarily disable write protection when you want to, for example, rewrite data that is being write-
protected, set the most significant bit of address 0000
Disabling Write Protection for all OMRON-made RFID systems:
To disable write protection in order to, for example, use the entire memory area of the ID Tag as user
memory, use either of the following methods to set all of the ID Controllers.
• Using the DIP Switch (when pin 1 on SW3 is set to OFF):
Pin 7 on SW4: Set write protection to "ON" to disable write protection.
• Using the Internal Setting (when pin 1 on SW3 is set to ON):
PARAMETER SET (SP) COMMAND processing code "H": Set the write protection setting to "00" to
disable write protection.
Precautions on Using Write Protection
The write protection function is supported only for these OMRON ID Controllers. It is not valid for reader/writers manu-
factured by other companies.
