8The USB Interface
The features covered in this section of the manual are available on models fitted with the
optional USB Interface or the Data Recorder (which includes the USB Interface).

Using the USB Port

The USB Interface option allows the user to upload or download instrument settings to or
from a USB memory stick. This allows easy configuration of multiple instruments by copying
from one to another, or to transfer it to or from the PC configuration software. If the Data
Recorder or Profiler options are fitted, recordings and profile information can also be
transferred via USB memory stick. Refer to the USB Menu section for more details.

USB Memory Stick Folders & Files

When a USB stick is inserted, the instrument looks for, and if necessary creates the DEVICE,
CONFIG, PROFILE and RECORDER folders. Files must be located in these folders in order
to be used. When preparing to upload files from your PC, ensure that you save them to the
correct folder on the memory stick.
DEVICE –This folder must be located in the
Root of the USB memory stick
CONFIG –Configuration files (*.bct)
PROFILE –Profile program files (*.pfl)
RECORDER –Recorder log folders/files The
user is asked for a new recorder sub-folder
name before transferring recorder data to USB.
The instrument stores the log files (*.csv) in this
folder.
CAUTION:
If the file or folder named already exists, data will be overwritten
The first recorder log file written is named 000001-1.csv and placed in the new Recorder
sub-folder. Stopping/starting a recording does not create a new file, but each time the
parameters being recorded are changed a new file is created (e.g. 000002-1.csv then
000003-1.csv etc). If any of these files would exceed the maximum spreadsheet size of
65500 data lines, a new file is created with the last digit incremented by 1 (e.g. 000001-2.csv
then 000001-3.csv).
Note:
To speed up the disk operation, keep the number of files in these folders to a minimum.
CAUTION:
Do not remove the memory stick from the USB port whilst a data transfer operation
is in progress. Data loss or corruption may result.
