simple text file as well as a software-dediated *.ttd file. If
Session Manager DB
software is used, database entries are also made. Full details about these rpocesses
are given in the appropriate
Session Manager
user guide.
Some TagMate USB
®
units are equipped with an internal wireless modem (GPRS or
WiFi). In this case, the transfer of files can be activated by DIP switch 4, and will
occur automatically to an Internet server
13
whenever files are in the TAGMATE\DATA
folder on the USB drive. In this case, TagMate USB
®
places files into the BACKUP
folder, and they would not be found by Session Manager as just described unless
they are moved back into the outer DATA folder.
Some USB drives are pre-loaded with an “autorun” utility program that carries out
file transfer operations, much as they would be performed by an internal wireless
modem on the TagMate USB
®
, whenever the USB drive is plugged into a computer
(no software installation required).
Files Transferred Into TagMate USB
®
The processes described above for automated retrieval of tag data files from a USB
drive may also operate in the reverse direction: updating of utility files that are used
by the TagMate USB
®
. These utility files include firmware files and other
configuration files. The TagMate USB
®
’s startup process will include a check for
these utility files whenever a USB drive is plugged in, and the unit will automatically
update itself from these files as needed.
Reading Tags in Continuous Mode
Continuous Mode is a special way of logging data, whereby a tag will keep logging
after reaching its initial capacity of 702 data points, up to a total duration of 16,000
log intervals. After reaching the 702 data point capacity, the tag begins continually
replacing the oldest data points with the newest ones, creating a “circular buffer” for
temperature readings. A tag is originally placed into Continuous Mode by
Session
Manager(DB)™ Software
(version 2.3 or later). TagMate USB
®
will not perform this
function.
The significance of Continuous Mode goes far beyond an extension of the timespan of
logging. In effect, this mode of operation consolidates two steps down to just one.
As seen above, normal logging operations require, at minimum, a CONFIG-START
step and a READ step. The tag’s time frame for logging, the Info field, and the alarm
criteria are all determined at the CONFIG-START step; the READ step adds only
time-temperature measurements to these existing configuration parameters, then
analyzes for alarms and summary data. In Continuous Mode, on the other hand,
only the log interval is set upon starting a tag, and all other aspects are controlled by
the READ process. In effect, each READ process will serve as a unique one-step
monitoring “session”.
Configuration Parameters in Continuous Mode
The configuration parameters and Info field for a tag in Continuous Mode are
determined at the time of reading, in essentially the same manner as for a CONFIG-
START process.
