UCODE G2iL and G2iL+
• ChangeEAS does not succeed: If the interrogator does not observe a reply within
20 ms then the ChangeEAS did not complete successfully. The interrogator may
issue a Req_RN command (containing the handle) to verify that the G2iL is still in the
interrogator's field, and may reissue the ChangeEAS command.
Upon receiving a valid ChangeEAS command a G2iL will perform the commanded
set/reset operation of the PSF bit of the Configuration Word.
If PSF bit is set, the EAS_Alarm command will be available after the next power up and
reply the 64 bit EAS code upon execution. Otherwise the EAS_Alarm command will be
ignored.
10.7.6 EAS_Alarm
Upon receiving an EAS_Alarm custom command the UCODE G2iL will immediately
backscatter an EAS-Alarmcode in case the PSF bit of the Configuration Word is set. The
alarm code is returned without any delay caused by Select, Query and without the need
for a backend database.
The EAS feature of the G2iL is available after enabling it by sending a ChangeEAS
command described in Section 10.7.5 “
ChangeEAS
3
” or after setting the PSF bit of the
Configuration Word to ’1’. With the EAS-Alarm enabled the G2iL will reply to an
EAS_Alarm command by backscattering a fixed 64 bit alarm code. A G2iL will reply to an
EAS_Alarm command from the ready state only. As an alternative to the fast EAS_Alarm
command a standard SELECT
2
(upon the Configuration Word) and QUERY can be used.
If the PSF bit is reset to '0' by sending a ChangeEAS command in the password protected
Secure state or clearing the PSF bit the G2iL will not reply to an EAS_Alarm command.

UCODE G2iL and G2iL+
The EAS_Alarm command is structured as following:
• 16 bit command
• 16 bit inverted command
• DR (TRcal divide ratio) sets the T=>R link frequency as described in EPCglobal Spec.
6.3.1.2.8 and Table 6.9.
• M (cycles per symbol) sets the T=>R data rate and modulation format as shown in
EPCglobal Spec. Table 6.10.
• TRext chooses whether the T=>R preamble is pre-pended with a pilot tone as
described in EPCglobal Spec. 6.3.1.3.
A preamble must be pre-pended the EAS_Alarm command according EPCglobal Spec,
6.3.1.2.8.
Upon receiving an EAS_Alarm command the tag loads the CRC5 register with 01001b
and backscatters the 64 bit alarm code accordingly. The reader is now able to calculate
the CRC5 over the backscattered 64 bits received to verify the received code.

11. Limiting values
[1] Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the
device. This is a stress rating only and functional operation of the device at these or any conditions other
than those described in the Operating Conditions and Electrical Characteristics section of this specification
is not implied.
[2] This product includes circuitry specifically designed for the protection of its internal devices from the
damaging effects of excessive static charge. Nonetheless, it is suggested that conventional precautions be
taken to avoid applying greater than the rated maxima.
[3] For ESD measurement, the die chip has been mounted into a CDIP20 package.
