b. DataBANK™ Card
The DataBANK™ card is a PCMCIA card that interfaces with the controller through the programming slot and can
download the data at a much faster rate, when compared to the PC or DataReader. Files downloaded to Data
-
BANK card files are accessible through an Omni PC Card Drive. The files can then be viewed using the DataLINE
software.
c. DataLINE
The DataLINE software for a personal computer is supplied on both floppy disks and CD. This software allows
interrogation, configuration variable assignment, screen view of the data, hard copy report generation, cold treat
-
ment probe calibration and file management. Refer to Data Retrieval manual 62-10629 for a more detailed expla
-
nation of the DataLINE interrogation software. The DataLINE manual may be found on the Internet at
www.container.carrier.com.
d. Communications Interface Module
The communications interface module is a slave module, which allows communication with a master central monitor
-
ing station. The module will respond to communication and return information over the main power line. With a com
-
munications interface module installed, all functions and selectable features that are accessible at the unit may be
performed at the master station. Retrieval of all DataCORDER reports may also be performed. Refer to the master
system technical manual for further information.

USDA Cold Treatment
Sustained cold temperature has been employed as an effective post-harvest method for the control of Mediterra
-
nean and certain other tropical fruit flies. Exposing infested fruit to temperatures of 2.2°C (36°F) or below for spe
-
cific periods results in the mortality of the various stages of this group of insects.
In response to the demand to replace fumigation with this environmentally sound process, Carrier has integrated
Cold Treatment capability into its microprocessor system. These units have the ability to maintain supply air tem
-
perature within one quarter degree Celsius of set point and record minute changes in product temperature within
the DataCORDER memory, thus meeting USDA criteria. Information on USDA is provided in the following sub-
paragraphs.
a. USDA Recording
A special type of recording is used for USDA cold treatment purposes.Cold treatment recording requires three
remote temperature probes be placed at prescribed locations in the cargo. Provision is made to connect these
probes to the DataCORDER via receptacles located at the rear left-hand side of the unit. Four or five receptacles
are provided. The four 3-pin receptacles are for the probes. The 5-pin receptacle is the rear connection for the
Interrogator. The probe receptacles are sized to accept plugs with tricam coupling locking devices. A label on the
back panel of the unit shows which receptacle is used for each probe.
The standard DataCORDER report displays the supply and return air temperatures. The cold treatment report dis
-
plays USDA #1, #2, #3 and the supply and return air temperatures. Cold treatment recording is backed up by a bat
-
tery so recording can continue if AC power is lost.
b. USDA/ Message Trip Comment
A special feature in DataLINE allows the user to enter a USDA (or other) message in the header of a data report.
The maximum message length is 78 characters. Only one message will be recorded per day.

USDA Cold Treatment Procedure
The following is a summary of the steps required to initiate a USDA Cold Treatment:
1. Calibrate the three USDA probes by ice bathing the probes and performing the calibration function with the
DataLINE. This calibration procedure determines the probe offsets and stores them in the controller for use
in generating the cold treatment report. Refer to the Data Retrieval manual 62-10629 for more details.
2. Pre-cool the container to the treatment temperature or below.
3. Install the DataCORDER module battery pack (if not already installed).
