A Pre-trip test may be initiated by use of the keypad or
via communication, but when initiated by communica-
tion the controller will execute the entire battery of tests
(auto mode).
At the end of a pre-trip test, the message “P,” “rSLts”
(pretest results) will be displayed. Pressing ENTER will
allow the user to see the results for all subtests. The
results will be displayed as “PASS” or “FAIL” for all the
tests run to completion.
A detailed description of the pre-trip tests and test
codes is provided in
Table 4–7 . Detailed operating
instructions are provided in Section 5.7 .
4.8 DATACORDER
The Carrier Transicold “DataCORDER” software is
integrated into the controller and serves to eliminate
the temperature recorder and paper chart. Data-
CORDER functions may be accessed by keypad selec-
tions and viewed on the display module. The unit is
also fitted with interrogation connections (see
Figure
4.1 ). A personal computer with Carrier Transicold
DataLINE software may also be used to download data
and configure settings.
The resulting file uses a proprietary file format that pro-
tects it from potential tampering or altering of data.
Therefore, once downloaded, all dcx files shall be con-
sidered secured. The DataCORDER consists of:

4.8.1 DataCORDER Software
The DataCORDER Software is subdivided into Opera-
tional Software, Configuration Software, and the Data
Memory.
a. Operational Software (dC Function Codes)
The Operational Software reads and interprets inputs
for use by the Configuration Software. The inputs are
labeled Function Codes. Controller function codes (see
Table 4–8 ), allow the operator to examine the current
input data or stored data. To access these codes, do
the following:
1. Press the ALT. MODE and CODE SELECT keys.
2. Press an arrow key until the left window displays
the desired code number. The right window will
display the value of this item for five seconds
before returning to the normal display mode.
3. If a longer time is desired, press the ENTER key
to extend the time to 30 seconds.
b. Configuration Software
The configuration software controls the recording and
alarm functions of the DataCORDER. Reprogramming
to the factory-installed configuration is achieved via a
configuration card. Changes to the software may be
made using the DataLINE integration software.
