GSR2700 IS Operations Manual 53
Collecting Data Chapter 6
6.4 Data File Naming
Auto-generated file names consist of an eight-character base
followed by a .PDC extension, as follows:
####$$$%.PDC
The eight characters are derived as shown in Table 15.
For example, a GSR2700 IS might have a serial number such as
NZH05410087
. If the day is January 25 (025 UTC day of the
year), and this is the 15th session created that day (session ID E),
the file name would be
0087025E.PDC
.
In the unlikely event of a conflict between an auto-generated file
name and an existing file, the GSR2700 IS resolves the conflict by
creating a file name whose first character is a tilde (~), followed
by a 7-digit random number, and a .PDC extension (for example,
~9368412.PDC).
