DLR-TL001 Specifications
16 DLR-TL001
Air Link Protocol Characteristic (Physical
Layer)
In general, the DLR-TL001 tag satisfies the EPCglobal
C1G2 physical layer protocol specification, with the excep-
tion of the following points:
• Reader to tag data rates: the interrogator can only
use Tari value of 25 μsec. Tari values of 12.5 μsec and
6.25 μsec are not supported.
• Tag to reader encoding: the encoding format, selected
in response to the interrogator commands, can be
either FM0 or Miller (M=4) as specified in [RD5], chap-
ter 6.3.1.3.2 of. Miller data encoding with M=2 and
M=8 are not supported.
• Tag to reader data rates: the DLR-TL001 tag supports
tag to interrogator data rates and link frequencies as
specified in the following table:
Table 5. Tag to reader data rates
• Commands: all the EPC C1G2 mandatory commands
are supported as well as the optional Access com-
mand. For more details see the Product Reference
Guide (PRG).
