INTRODUCTION
There are two meters in the AcquiSuite™Series: the AcquiSuite™Ally 12 & Ally 48. These meters monitor
the voltage, current, power, energy, and many other electrical parameters on single and three-phase
electrical systems. A AcquiSuite™Ally meter uses direct connections to each phase of the voltage and
current transformers to monitor each phase of the current. Information on energy use, demand, power
factor, line frequency, and more are derived from these voltage and current inputs.
The AcquiSuite Ally is the perfect companion to the Obvius data acquisition product line. The Ally 48’s
versatile power metering functionality continues the Obvius mission of lowering the total cost of collecting
data by reducing install complexity, and increasing flexibility. The plug-and-play integration ensures the
hundreds of data points are immediately captured and made available for countless applications.
The AcquiSuite™Ally meter communication interfaces include Ethernet (LAN), RS-485 serial, BACnet
MS/TP and Modbus RTU are the two communication protocols that operate over an RS-485 serial network
and BACnet IP and Modbus TCP are supported over Ethernet. A USB port is also provided as the preferred
connection for on-site configuration and can be run concurrently with an RTU.

PLANNING FOR FIELD INSTALLATION
Project Manager Aspects
Meter installation often includes coordination between individuals or groups of people with different
responsibilities. Spend a few minutes considering who will be executing each portion of the installation
and what tools are needed at each stage. Things to consider include determining how to communicate
with the meter, setting address configuration, installing Obvius Ally Configuration Console, access to PIN
number, etc. The more tasks completed before installation, the fewer tasks required in the field. The
following section gives an overview of these activities followed by details in the next section.
CONFIGURATION &DATA VIEWING OPTIONS
The AcquiSuite™Ally meter has multiple methods for configuration and data viewing. The most powerful
interface is provided with a PC, Laptop or Tablet running Windows and is encouraged for complex
installations. The Ally Configuration Console software is required for configuring advanced functions like
alarms. The second interface is intended for smart phones or tablets that can connect over USB, Ethernet,
or Wi-Fi. The third interface (LCD) is intended for intermittent end user observation and is restricted in
capability. Utilizing the AcquiSuite DAS interface can also be used for configuration, if communication
settings are already established. The feature set of each interface is summarized next.

METER CONFIGURATION - DETAILS
This section is written to support setting up the AcquiSuite™Ally meter in an office
environment and configuring the power meter for a pre-determined configuration. In
many cases the setup is standardized for an organization or project. In other cases, the
setup can be documented and forwarded to an electrician as a wiring schedule. The setup
can also be performed on site and reflect “as built” configurations.
•The Ally meter cannot be configured using Obvius Ally Configuration Console over a serial
port. RS-485 serial network configurations must be pre-configured or use Modbus / BACnet
hosts.
•This section describes the use of the Obvius Ally Configuration Console Windows Application.
If this interface cannot be used, refer to the section on using the simplified web browser
interface. The web browser can be accessed from the USB port to support Mac users.
Install the Software
Insert the Obvius Ally Configuration Console thumb drive into the computer or download from the Obvius
FTP site. (qualified Obvius personnel only)
The installer should start automatically. If it does not, browse the thumb drive and locate the
AllyConfigurationConsoleInstaller.exe program. Start the installer by double-clicking on it, and follow the
installer instructions.
CONNECTION & CONFIGURATION OPTIONS USING OBVIUS ALLY
CONFIGURATION CONSOLE
When the Obvius Ally Configuration Console application is launched, it
will prompt the user to select one of four connectivity options.
•Connect over USB (recommended)
•Connect over Ethernet
•Scan Network
•Launch Configurator (no meter connection available)
RECOMMENDED CONNECTION VIA USB AB CABLE
The preferred method for configuring the AcquiSuite™Ally meter from a
locally connected computer is through the USB interface which provides
power to the meter as well as communications.

AcquiSuite Ally 12 & 48 User Guide (Rev D)
17 | P a g e
1) Connect the Ally meter to a USB port of your computer using a
USB A to B cable.
a. If equipped, the LCD display is the most visable
indication of a running meter.
b. For meters without a display, a green flashing LED on
the circuit board indicates that the AcquiSuite Ally
meter has booted and is running.
c. The meter will draw 450mA from the USB port which could potentially overload
“out of spec” USB hosts. If the meter fails to power from USB, an alternate
configuration to power the meter must be used.
2) Launch the Obvius Ally Configuration Console application and press the “CONNECT
OVER USB” button on the pop-up window.
The meter should now be communicating. Obvius Ally Configuration Console offers visual guides and
context help to facilitate meter configuration. Please read the Obvius Ally Configuration Console overview
section (below) or watch the tutorial videos for additional information on configuring the meter. By
default, Ally12 & Ally 48 meters are configured for DNS Ethernet addressing. A very common configuration
sequence is using USB to configure a meter for Ethernet communications at a static IP
address and then switching from USB over to Ethernet to locate it. This is facilitated in
Obvius Ally Configuration Console by pressing the “Refresh Connectivity” icon located in
the upper right hand corner.
ETHERNET NETWORK CONNECTION
Configuring the Ally meter over Ethernet requires that the meter be powered from an alternate
connection. The PSHD does not support Power Over Ethernet (POE). If the meter is already installed
within the buildings electrical network, closing the AC breaker (or approved disconnect) will turn on the
meter through the meter’s internal power supply. In the rare case that a computer’s USB port cannot
provide 500mA of current, an AC / USB charger or a USB battery can be used as a power source while
using Ethernet for communications. .
•Both the “Network Scan” and “Connect Over Ethernet to IP …” options require
that a valid network connection exists between the AcquiSuite Ally meter and
configuration PC. This is a common startup issue.
DYNAMIC HOST CONFIGURATION PROTOCOL (DHCP):
Ally meters are shipped in DHCP mode to prevent IP conflicts with other equipment. The meter is
expecting to receive an IP address from a DHCP service provided by a router, Layer 3 switch, or a server

AcquiSuite Ally 12 & 48 User Guide (Rev D)
18 | P a g e
providing DHCP service. Under this configuration, as long as the AcquiSuite Ally meter and the host PC
are requesting an IP address from the same DHCP service provider, they will be able to communicate.
Upon powering up, the AcquiSuite Ally meter will indicate the IP address on the LCD display (if
equipped) or can be found using the Network Scan function.
DIRECT:
When a PC is directly connected to an Ally meter via an ethernet cable, no DHCP service exists. This
configuration can be made to work, but requires changes to either the meter communication settings or
the PC network configuration.
LCD Display
For units equipped with an LCD display navigate to
Communications  Ethernet Settings  DHCP  OFF
Change the IP address in the meter to match the subnet of your PC’s IP address, making the
meter IP unique, or note the current address on the meter and prepare to configure your PC’s IP
settings as shown below.
Once the PC and Ally meter are set to communicate on the same IP subnet:
1) Launch the Obvius Ally Configuration Console application and enter the IP address of
the meter (shown as the factory default)
2) Press the “Connect over Ethernet” button on the pop up window.
3) The meter should now be communicating. Obvius Ally Configuration Console is an intuitive
application; read the Obvius Ally Configuration Console overview section below.

AcquiSuite Ally 12 & 48 User Guide (Rev D)
19 | P a g e
No LCD Display
An AcquiSuite Ally meter without a display can only communicate directly with a PC over
ethernet if the IP address of the meter is set to static. Setting the IP address must be done
ahead of time using another interface (such as USB or serial).
NETWORK SCAN
Network Scan is a feature for monitoring previously installed and configured AcquiSuite Ally meters over
an Ethernet network. Network Scan will broadcast a UDP discovery packet on the same network as the
PC running the Obvius Ally Configuration Console application. Normally this will be performed on a
corporate network running DHCP. Any PowerScout HD meter that responds will be displayed in a table
that includes the system description register, IP address, serial number, and communication
configuration.
Highlight the desired meter and select OK, Test or Setup. Note that the effectiveness of this technique is
highly dependent on the configuration of the PC running Obvius Ally Configuration Console (which may
have more than one network card) and the network configuration. Rescans can be used to make
multiple attempts to locate a particular meter on busy networks (UDP has no built-in retry provisions).
LAUNCH CONFIGURATOR
The final option in the Obvius Ally Configuration Console Connect to Meter pop-up window is “Launch
Configurator”. This option allows for the creation of a meter setup or alarm table for future use without
connecting to a meter. After prompting the user for a meter model (shown below), Obvius Ally
Configuration Console launches under a mode with restricted functionality. This mode operates on files
only.
