manual interface. Once stopped, the logging activity can be restarted only
after the tag has been reset using the RST bit. Default value is 0.
3 - DE
(RW) - Delay_Enable bit: It is used to enable(1)/disable(0) the usage of
the SAMPLING_DELAY register. If enabled, the first sample's acquisition is
done SAMPLING_DELAY second after the start of the logging activity. Default
value is 0.
4 - RFSL (RW) -
RF_Sensitivity_Level: register used to set the sensitivity level
of radio frequency front-end. Three levels can be set : 3 = max, 1 = min.
The default value is 1.
5 - MKT
E (RW) - Mean_Kinetic_Enable bit: if 1 enables MKT calculation.
Default value is 0.
6 - ARRE (R
W) - Arrhenius_Enable bit: if 1 enables the calculation of the
remaining Shelf Life (SHL_TIME) of the product using the Arrhenius equation
with linear approximation. Default value is 0.
11 - SD (RW) -
Stop_Disable bit: when 1, the DLR-TL001 button cannot be
used to stop the logging activity. Default value is 0.
8 to 10 & 12 to 15 Bits are RFU (RW) bits (Reserved for Future Use)
SAMPLING_DELAY Register (RW)
Register Address Op. Default
SAMPLING_DELAY 0x0B RW 0x0E10
Sampling_Delay register defines the delay, in seconds, of the first acquisi-
tion after the start of the logging activity.
Register value range is 0 to 65535;
default value is 3600 (seconds) corresponding to 1 hour delay. The sampling
delay is activated if the corresponding bit on the CONTROL register (DE) is
enabled.
INIT_DATE Register (RW - 2 words)
Register Address Op. Default
INIT_DATE_L 0x0C RW 0x0000
INIT_DATE_H 0x0D RW 0x0000
The Init Date register is used to keep track of time and it is expressed in
Unix time format. Default register's value is 0 that corresponds to midnight
(UTC) January, 1 1970. If date value is 0, the internal timer is not active.
When this register is set to a non-zero value the internal 32 bit register
timer starts. The INIT_DATE register MUST be set AFTER the RESET operation
on the tag. INIT_DATE_L must be written before INIT_DATE_H. The INIT_-
DATE register is set to 0 after a reset operation.
ETA Register (RW - 2 words)
Register Address Op. Default
ETA_L 0x0E RW 0x0000
ETA_H 0x0F RW 0x0000
The Estimated Time of Arrival register (expressed in seconds) defines the
maximum time, computed from shipping date, required to arrive at destina-
