Starting Applications

The GUI (User Applications) and the DO Server can be run on any Linux machine with python3.6. Before starting the ADC application (Device Application), all the dependencies, described in section Dependencies, have to be installed.

The first application that has to be run is the Server. When the Server is already started, GUIs and ADC nodes can be run in any order.

Before starting any of the applications, start the virtual environment and install the Distributed Oscilloscope, as described in section Applications.

Server Application

To start the Server Application, run in terminal:

$ dist_osc_server

Optional arguments:

• port_user – port of the Server exposed to the User Application, default value – 8003
• port_device – port of the Server exposed to the device, default value – 8023

GUI:

Before starting the GUI applications, find out what is the IP address of the Server: SERVER_IP_ADDRESS. You can check it using the command:

$ ifconfig

To start the GUI, run in terminal:

$ dist_osc_gui --ip_server SERVER_IP_ADDRESS

Required arguments:

• ip_server – IP address of the Server

Optional arguments:

• port – port used on the current machine to listen for notifications and acquisition data, default value – 8001
• port_server – port used on the Server to listen for the requests from the GUI, default value – 8003

ADC application:

If the Server and the ADC device are in different local networks, before staring the ADC applications, find out what is the IP address of the Server: SERVER_IP_ADDRESS. If the IP address of the Server is not provided, Zeroconf will be used to automatically find out this information.

Important

The Zeroconf will only work if the Server and the ADC are in the same local networks. Otherwise, the IP of the Server has to be provided manually.

To start the GUI, run in terminal:

$ dist_osc_adc_node --ip_server SERVER_IP_ADDRESS

Optional arguments:

• ip_server – IP address of the server
• port_server – port of the server used to listen for notifications and acquisition data, default value – 8023
• port – port used on the current machine to listen for the requests from the Server, default value – 8000
• pci_addr – PCI address of the desired board, default value – 0x01

Examples configuration:

Supposing that the IP address of the Server is 128.141.79.22, the ADCs are installed in the same machine and the PCI slots where the ADCs are installed are 01 and 02, the applications have to be started with the following parameters:

$ dist_osc_server
$ dist_osc_gui --ip_server 128.141.79.22
$ dist_osc_adc_node --ip_server 128.141.79.22 --port 8000 --pci_addr 01
$ dist_osc_adc_node --ip_server 128.141.79.22 --port 8001 --pci_addr 02
