5. The downloaded data will now be in a folder, inside the Data Transfer USB memory device “DOWNLOAD”
folder. Each day data is extracted to the USB a folder will be created. The folder naming convention will
begin with the letters “DX” followed by the last two digits of the year, two digits representing the month and
two digits representing the day. For example a folder named DX140212 would contain data extracted Febru-
ary 12th, 2014.
6. Two files will be created inside the folder for each download. The file naming convention used is the last 8
characters of the Trailer ID followed by .zdx for the first file and a secondary file with the same name fol-
lowed by .zax.
If the same unit (with the same asset, trailer or car ID) is downloaded twice or more on the same day,
the earlier files will be overwritten. If the earlier files will be required for later review, ensure they are
transferred off the device before starting another download.
5.3.4 Installing Software
Instructions for installing software into the APX Control System from a Data Transfer USB memory device are
provided in Figure 5.8. If power is lost or USB removed, this procedure should be repeated. The screen may be
blank until the USB is reinserted.
Whenever installing new software, it is always a good idea to start the unit and give it a quick check
over prior to performing the operation. All units should have the software upgraded to the latest ver-
sion, provided for Carrier Transicold dealers on the TransCentral web site.
