2.1 Comments
Within the setup.txt file, it is useful to record comments documenting the
settings chosen and why some configuration choices were made. Comments
are also useful for temporarily disabling setting(s) for the purposes of testing
multiple settings.
Figure 2.1. Use of comments to switch between GPS
receivers.
To create a comment line in the setup file, place to forward slashes (“//”) at
the beginning of a line. The SDR2-USB will completely ignore any line that
begins with //. To disable a particular line temporarily, insert // at the
beginning of the line.
2.2 Setting date and time
The SDR2-USB features a real-time clock that reports a file’s last modified
date and time. The real-time clock accurate and battery-backed, so setting
the date and time is seldom necessary.
Unlike DataBridge SDR products equipped with a configuration port,
setting the SDR2-USB’s date and time is a four-step process.
Step 1: Edit setup.txt
Add CurrentDate= and CurrentTime= lines to the setup file (see
Figure 2.2) with a time value 1-2 minutes ahead of the current time. The
year field must be specified using 4 digits, while all other fields must be
specified using 2 digits. Date is specified in YYYY/MM/DD format, and
time is entered using 24-hour format. Take note of this time for use in
step 3.
