^RE - Enable RFID EAS Bit
Sets or clears the electronic article surveillance bit on a tag.
Some ISO 15693 tags carry an electronic article surveillance bit, which makes the
exit gate of a store sound. ^RE sets or clears the bit. A tag without the bit
ignores the command, so ^RE is safe in a format that runs across mixed media. A
format that appears to operate can also do nothing at all.
Syntax
^REt,rSupport
Accepted and skipped, because it configures the printer rather than the label. It cannot change the rendered output, and Labelary skips it too.
Flips a theft-detection bit inside the transponder, and prints nothing. The renderer does not parse this command. It reports IGNORED_COMMAND at info severity, which does not reach X-Warnings. Labelary is also silent, so the rendered label is identical in both engines and with or without the command. — not pinned by a test
Labelary renders this command.
Parameters
tEnable the E.A.S. bitoptional · Y or NSets or clears the electronic article surveillance bit. Only ISO 15693 transponders that implement E.A.S. respond; any other tag ignores the command.
- Default
- N
- Invalid value
- not documented, and we have not measured it. The renderer does not parse this command or validate its arguments. The guide does not state what a printer does with an out-of-range value.
- Test coverage
- No documented value is exercised by a test (Y, N).
Y- Enable E.A.S.
N- Disable E.A.S. (default)
rNumber of retriesoptional · integerHow many times the printer retries the operation on a single tag before it stops.
- Default
- 0
- Accepted range
- 0 to 10
- Invalid value
- not documented, and we have not measured it. The renderer does not parse this command or validate its arguments. The guide does not state what a printer does with an out-of-range value.
- Test coverage
- No test at the minimum, maximum or one step outside the range.
Behavior
The bit is inside the transponder and has no printed form. The printer retries a
failed write r times and then stops.
The example in the guide writes the enable flag in lower case, ^REy,5. The
parameter table in the guide lists Y. Formats in the field therefore use either
case.
Example
Enabling the EAS bit on the tag behind a single line of text:
