Acumen SDR2-USB manual Comments, Setting date and time

Configuring the DataBridge SDR2-USB SDR2-USB Configuration Guide rev 1.0

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.
