Getting Started

Front panel

Symbol	Description
	DC 12 V Power Barrel Connector Jack 2.10mm ID (0.083”), 5.50mm OD (0.217”). Power consumption is max. 15W.
	microSD card connector. Firmware and software storage device.
	LEDs. From the left: Sys, CPU, F2, F1. The state of F2 LED corresponds to the LOGIC IN input state. The state of F1 LED corresponds to analog signal coverage on any channel.
	miniUSB 2.0 compatible with USB gadget mode. Connecting the digitizer via this connector to a computer will create a new network interface on this computer and set up a local network on it. DPP static IP is 192.168.3.1
	1GbE RJ45 Ethernet socket. The Ethernet cable should be connected before powering on the device for proper network initialization over DHCP.
	miniUSB 2.0 Linux terminal (115200 8N1) based on the CP2102N. Download USB to UART Bridge VCP Drivers: https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers

DPP communication interfaces

Nucliflare digitizer is a stand-alone device based on the Linux operating system. Communication with the system is mainly based on the client/server model and network communication.

Note

Default DPP Username and Password:
Username: nucliflare
Password: nucliflare

Debug interface

Connect DPP to the PC using usb_serial , check the serial port number, and open any serial terminal software.

USB 2.0 Gadget interface

Connect DPP to the PC using usb , local network between DPP and PC will be established. Run Nucliflare DPP software. DPP static IP is 192.168.3.1

Ethernet connection

Connect DPP to local network using eth connector. Check IP address using Debug interface or USB 2.0 Gadget interface and ssh connection.

Note

The IP address of a device on a local network usually remains constant for the next power cycles.

Running digitizer & quick start

Connect DPP to local network 
Plug in power adapter  
Check IP address using Debug interface or USB 2.0 Gadget interface and ssh connection.
Run Nucliflare DPP software.
