When powered up, the Pixie-Net automatically boots the FPGA configuration and starts the Linux OS. There are several ways for a user to connect to the Pixie-Net Linux OS:
- Serial port via USB-UART
- Network ssh terminal
- Web server
- SMB (Samba) file sharing
Option 1 requires serial port drivers on a USB master (PC). Options 2-4 require knowledge of the Pixie-Netís IP address. After logging in, a few setup programs have to be executed to set acquisition parameters (for example, specify gain and automatically adjust DC offsets).
At this time, data acquisitions are started via terminal command line programs. Login is required if over the network. Progress can be monitored through a web interface that displays MCA spectra and run statistics. This is a webserver running on the Pixie-Net Linux system. After the run, MCA and list mode data files can be downloaded via the webserver or though file sharing in Windows Explorer.
