Use and Operations

Warning

Our devices are capable of RF transmission on bands or frequencies subject to regulatory oversight. It is the exclusive responsibility of customers and end users to ensure use of this device meets local regulatory and legal standards, as they may apply to you and the band of interest. You can find the full list of Terms and Conditions here.

The following remarks are applicable to all Per Vices produces.

UHD

The device can be configured using the Per Vices UHD drivers. This allows for easy interface with software devices, and provides some compatibility with USRP devices.

Note

We maintain libUHD as a fork and pull in upstream changes from time-to-time. Since we use fundamentally different hardware, we cannot ensure total compatibility - but we try our best to support the features that matter for our customers.

If you don’t already have libUHD, checkout this section that shows you how to set it up.

Example Programs

Example programs, including source code, are included in the libUHD repository, under the uhd/host/examples path, and may be compiled with the -DENABLE_EXAMPLES=ON cmake flag.

Web UI

You can access the web interface by typing the IP address of the device into your browser. This directs you to a SCADA-like interface where you can easily visualize and configure the radio chain and DSP carried out on the device. Figure 1 shows the Web UI for Crimson TNG.

SSH and Command Line

You can also access and configure the device over SSH using command line parameters. This is primarily done using two programs: uart-app and mem. The uart-app programs allow you to send commands over the UART bus to radio peripherals (like ADCs, DACs, or Amplifiers), and the mem application allows you to read and write to the memory space shared between the HPS and the FPGA.

Rebooting the device remotly

To reboot the device without using the power switch on the device, you will need to connect to device under user dev0 (the default password is dev0) and issue a restart command. This can be done as follows:

ssh dev0@192.168.10.2 # ip address of management port
sync
sudo systemctl reboot # alternativly sudo reboot
