Step 2: Establish a Connection with the Unit
Wired or Wireless Single PC Connection
The most convenient way to connect a Dedicated Tablet or any other PC is
by using a Wi-Fi or wired Ethernet link. It is best to make only one
connection type at time, and when a wired connection is used, disconnect or
disable the wireless link.
Technically, any of the available Ethernet ports can be used for a single PC
connection. However, the most recommended is a LAN1 option (as shown
above) because of the integrated DHCP server available thru that port.
When connected, a PC will automatically obtain an IP address configuration
which allows a seamless connection to the BLACKBOX Portable’s internal
WEB/FTP servers as well as to a router management WEB server.
Integrated Router
The G4500 BLACKBOX Portable (not available on the G3500) contains an
integrated IEEE 802.11g/b router preconfigured as an industry standard
access point. This is to provide the most convenient and simplest
connectivity with the Dedicated Tablet PC.

This section of the Quick start Guide describes how to begin working with
PQSCADA and Investigator software to review and analyze data in recorded
data files. Use it to become familiar with the PQSCADA and Investigator
interface and features. The BLACKBOX CD enclosed contains all of the
required software in an easy to use Auto-Run format.
PQSCADA/Investigator Key Features & Benefits
Auto reports generation: Automatic reports are generated through the
pre-defined Tasks functions that allow you to set regularly scheduled
exports – COMTRADE, PQDIF, and/or reports – PDF, EXCEL,
HTML according to a specified event or time trigger (monthly, daily,
weekly, and fixed).
Automatic Notification: Three possible notification possibilities: email,
SMS, and Pop-Ups. The notification is triggered by events by predefined or user defined electrical events.
Analyze the data: Using a series of views to see different aspects of it,
including summaries, trends, spectral of Volt/Amps/Hz, events,
harmonics, THD, Flicker, power and energy.
Multiple device synchronization: Elspec’s Investigator allows you to
view multiple devices synchronized in time. You can adjust the data
shown by turning on and off display of different devices and select other
parameters. You can focus on the specifics that help you analyze and
understand the power quality data.
Generate reports: the Investigator software application builds reports
based on EN 50160 and other specific national standards. Additional
standards templates can be modified upon request.
Organized Data: by establishing a Node/Site all devices are mapped on
the tree structure for easy navigation and orientation of the recorded
data.
