Collecting Data
The eight characters are derived as shown in Table 26.
For example, a GSR2700 ISX receiver might have the serial
number
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
.
A conflict between an auto-generated file name and an existing
file name is unlikely, but if it occurs, the GSR2700 ISX resolves it
by creating a file name as follows: the first character is a tilde (
~
),
followed by a 7-digit random number and a
.PDC
extension (for
example,
~9368412.PDC
).
7.4 Data Storage Capacity
Table 27 indicates the approximate number of hours of data
logging to the internal memory for several recording intervals
based on the standard 64 MB internal memory.
NOTE For information about how to download data from internal
memory, see Section 5.2, Setting Up at the Office , page 38.
