INTRODUCTION
PowerScout meters monitor the voltage, current, power, energy, and many other electrical parameters
on single- and three-phase electrical systems. A PowerScout meter uses direct connections to each
phase of the voltage, and uses current transformers to monitor each phase of the current. Information
on energy use, demand, power factor, line frequency, and more are derived from the voltage and
current inputs.
The communications interface to the meters is an RS-485 serial or Ethernet connection that uses the
BACnet Master Slave Token Passing (MS/TP) protocol or Modbus protocol for sending commands and
retrieving data. A separate remote terminal unit (RTU), Data Logger, or Building Management and
Control System is usually connected to the PowerScout to provide data recording and trend logging plus
a human interface or display.
POWERSCOUT 3037 SERIAL/POWERSCOUT 3037 ETHERNET
The PowerScout 3037 is light-weight and
compact enough to mount within an electrical
panel. It is used for long-term monitoring of
electrical systems.
Up to 127 PowerScout 3037 serial meters may be
connected to a single BACnet MS/TP network for
monitoring and recording power usage at
multiple locations within a single site. Up to 247 serial meters may be connected to a Modbus RTU
network. You may connect as many Ethernet units as equal to the amount of available IP Addresses.
There is a configurable digital pulse output port on the PowerScout 3037 that can be used to output
kWh, kVARh, or kVAh pulses to external devices, or to toggle on and off to control a remote device or
relay.
PowerScout 3037 Optional Digital
Display
An optional visual display is available on the PS3037 which cycles through meter information and real-
time values of Volts, Amps, KW, KVA, KVAR, etc. See Appendix.
Unpacking the Unit
Your PowerScout meter comes with documents such as the Certificate of Calibration (COC) that has
information about the meter and is valuable for tech support. Be sure to set these documents aside in a
safe place when not in use.
If a Comm package was purchased as well, look for the ViewPoint software and the USB adapter. Verify
that all connectors are included (CT, voltage, comm, pulse).

PREPPING FOR FIELD INSTALLATION
There are multiple tasks that are typically completed before heading to the field, usually by your
technical support personnel. These include determining how to communicate with the meter, setting
address switches, installing ViewPoint, etc. Communication configuration must be set up in the
ViewPoint software even if you use a separate logger to record data. The more tasks completed before
installation means less time in the field.
These determinations figure into how you set up the PowerScout meter for operation:
BACnet vs. Modbus
Set the network address switches on the meter to either Modbus or BACnet
RS-485 vs. Ethernet
The type of connection is part of the configuration set up in the ViewPoint software
Laptop/PC for setup verification via USB
A convenient method for setup before going in the field, and once in the field, to easily read
real-time values
NOTE: Installation of the ViewPoint software and a communication cable should be completed and
tested with a meter prior to the field installation. A USB cable can be used when configuring the meter
in this manner.
Installing the ViewPoint Software
The ViewPoint software is designed to let you easily configure
the PowerScout for different current transformers, check
readings, and verify correct setup. All of DENT Instruments PowerScout meters use ViewPoint software
to communicate with the meter. It needs to be installed on any computer talking to the PowerScout
3037. ViewPoint is compatible with Windows® 7 (32 or 64 bit), Windows® 8 Pro, Vista (32 or 64 bit), or
XP.
Insert the ViewPoint CD into the CD-ROM drive.
The installer starts automatically. If it does not, browse to the CD and locate the ViewPointInstaller.exe
program. Start the installer by double-clicking ViewPointInstaller.exe.
The Communication screen is displayed when ViewPoint is first started. This is where the software
networking parameters are entered to match the PowerScout networking configuration (meter type,
COM port, baud rate, base address, etc.). ViewPoint remembers your last connection and displays those
previous selections when opening the software once again.
NOTE: ViewPoint software serves several functions, such as setting up a meter, getting real-time values,
and read/write registers and objects, but for the purpose of prepping for field installation only three are
important to the process: Communications, Meter Setup, and Comms Setup. The other functions are
described later in this document.
DID YOU KNOW?ViewPoint may be
installed on multiple computers.

18
Connecting a Communication Cable
There are various ways to communicate with a PowerScout meter and how you do so will determine
what type of cabling system you will use. To set up the meter, communication can be established with a
USB cable, an RS-485 adapter, or an Ethernet cable. Once in the field, communication between a
PowerScout meter and a logger is established with a RS-485 or an Ethernet connection. A RS-485
connection is limited in speed while an Ethernet connection is much faster.
NOTE: PowerScout meters are ordered from DENT Instruments based on the type of desired connection.
CONNECTING AND COMMUNICATING VIA A USB OR RS-485 ADAPTER
A type AB USB cable may be used between a PC and a PS3037 meter and is the preferred method for
setting up a PS3037 with Modbus protocols. The USB cable will also power the meter when connected
to a PC. When using a USB cable with a PC, each USB port on the PC generates a unique comm port in
the ViewPoint software, such as Com3 or Com4.
NOTE: A USB driver is installed when you install the ViewPoint software.
ViewPoint can read information through a USB, an RS-485 isolated COM port, or an Ethernet
connection. When the RS-485 connection is selected a base address is required (the base address is the
rotary switch settings). Address switches are ignored by both USB and Ethernet. When the Ethernet
connection is selected an IP address is required. The screen display changes based on your connection
selection.
The USB connector on the PowerScout 3037 can be used to power the unit when configuring it using
ViewPoint and Modbus protocols.
If connecting with a USB cable is not practical, the use of an RS-485 to USB adapter connected to your
PC may be used for communicating with your PowerScout. First, install the driver on the computer and
then complete the connection between the meter and the computer by plugging the RS-485 connector
into the meter.

19
Installing the RS-485 Adapter on a
Computer
NOTE: If ViewPoint was installed first, it needs to be restarted following an RS-485 driver installation. If
an RS-486 port does not appear in the drop-down list, the RS-485 was not installed correctly.
1) Insert the CD that came with the RS-485 adapter into your computer.
2) Insert one end of a USB cable into the RS-485 adapter and the other end into a USB port on the
computer.
3) The Found New Hardware Wizard window appears.
The window states “This wizard helps you install software for: Model USOPTL4,” and asks “What do
you want the wizard to do?”
4) Select Install the software automatically and click Next.
5) Click Finish when the installation is complete.
6) Remove the CD from your computer.
DID YOU KNOW?If an RS-485 adapter is used instead of a USB, an RS-485 driver must be installed
on your computer and power applied to the PowerScout meter before the software will function
properly.

The three wires coming from the RS-485 adapter are plugged into the COM connector. Insert each white
ferrule into the appropriate slots on the connector. The red wire inserts in the left slot (+), the black wire
in the middle slot (-), and the green wire in the right slot (Shield), Figure II-1 and Figure II-3. Verify that
the dip switches on the back of the RS-485 adapter are set to RS-485, Echo Off, 2 Wire, 2 Wire as shown
in Figure II-2 before plugging the adapter into the PowerScout 3037.

NOTE: USB is always active on the PS3037 (and the protocol is Modbus over the USB virtual
communications port).
NOTE: If ViewPoint was installed first, it needs to be restarted following a RS-485 driver installation. If a
RS-485 port does not appear in the drop-down list, the RS-485 was not installed correctly.
1) Select USB/RS-485 (MSTP) as your communication type.
2) Select PS/PS3037.
3) When connecting with an RS-485, enter a base address that matches the switches on the
PowerScout. A USB connection ignores address switches. See Setting the Network Address Switches
below.
4) When connecting with an RS-485, select Modbus or BACnet as your communication protocol. When
communicating over USB, whether the PS3037 is configured for Modbus or BACnet mode, the
PS3037 will communicate over the Modbus protocol.
5) Select the PC COM Port from the drop-down list. For a USB connection, select “COMxx DENT USB”
in the field, where “xx” is the port number. For an RS-485 connection using an RS-485 adapter,
select COMxx RS-485 Isolated Port (COMxx) where "xx' is the COM port number.
Default settings are used for the two remaining fields: Data Bits is 8N1 and the Baud Rate is 9600. When
BACnet is selected as your protocol an additional read-only field appears displaying the BACnet Device
ID.
