i.1 Install G4 LD Utility
G4 LD Utility (G4) software enhances the features, flexibility, and ease-of-use of Larson Davis instruments
by providing setup utilities, instrument calibration, computer-based control of the instrument, data
download and manipulation, printing, and export of data to third-party software for post processing and
analysis.
You can download G4 at http://www.larsondavis.com/G4 or find the software on the supplied USB drive.
Run LDsetup.exe to begin the download process. The install program prompts for any additional required
information. A PCB Piezotronics menu item will be created under the Program menu item in the Start
menu and a shortcut will be placed on the desktop.
i.2 Using A Digital Reference Manual
Larson Davis is committed to the green practices of limited paper waste. In this effort, we only offer
reference manuals in a digital PDF format. Digital notes and comments can be made in certain readers,
and you are encouraged to print any procedures or sections for quick references that fit your needs. Each

1.1 Overview
The SoundAdvisor Model NMS044 noise monitoring system (NMS044,
system) is the practical solution to long-term or short-term,
unattended sound level monitoring. Power is supplied by a 12 V
battery, and the system is charged by a solar panel, chosen specifically
for the area sunlight availability. It is lightweight, as little as 50 lbs, so
one person can carry to a site and setup within a few minutes.

NMS044 Reference Manual EPS/NMS044 Features 1-2
1.2 EPS/NMS044 Features
Acoustic Measurement
The area sound is measured with a prepolarized microphone and
preamplifier that are environmentally protected in a shroud on a
telescoping pole, which is mounted to the case.
Portable
The NMS044 can be deployed, before, during, or after you setup the
831C to make your measurements.
Low Power Consumption
LEARN MORE To learn more
about power consumption,
see “NMS044 Power Draw” on
page A-2.
A 12 V battery powers the system, which is charged by a solar panel
through a charge controller. The system can run, without recharging,
for about a week. Sunlight needed to reboot the system after a power
loss is minimal and full charge is reached in only a few hours.
Continuous Sound Measurements
If the batteries are ever completely depleted, the system will shut off
safely. When the battery is recharged sufficiently, it will power on and
the measurement will continue. This feature runs without any
prompting from the user.
Connectivity
Connect to a cellular network using the RV50 and access the 831C to
view/download data from a PC at anytime. Control the system from a
web browser from wherever you are.

2.1 Overview
TAKE NOTE This module
assumes that you have the
complete NMS044 and all its
components. For EPS044 the
setup is similar and the
following modules can be
adjusted to your equipment.
When you first receive the NMS044 system you will need to perform
several “first use” procedures to get your system ready for deployment.
While most steps can be done in the field or after deployment, these
steps are recommended to do prior.
2.2 Ready Battery
2.2.1 Install Battery
TAKE NOTE Connect all wires
and devices prior to turning
on the system.
Open case and carefully lift out the plate as to not pull any wires loose.
Set on an angle away from case, to expose the back.
Step 1 If not already in place, insert the battery (BAT019 or
BAT020) in the case inside the guide lines, with terminal
toward power block. See Figure 2-1 Battery Installation.
Step 2 Insert the connectors to the power distribution block - red
to red and black to black, side by side in any available
connector.
NMS044 Reference Manual Ready Battery 2-2
Step 3 Place the mounting plate back into the case, over the
battery, until set all the way in.
Step 4 If installing a BAT020, insert foam block to fill empty space
by the terminals.
FIGURE 2-1 Battery Installation
TAKE NOTE The 831C power
button 0 controls the power
in the whole system. It is used
to turn off and on the
NMS044. Additionally,
connecting the battery will
also turn the system on.
2.2.2 Charge Battery
It is recommended that you charge the battery prior to deployment. A
PSA039 AC Battery Charger is included for this purpose. Connect the
solar connectors together, and use the plug to connect to an external
power source (wall outlet) until charged. You will know it is fully
charged when the PSA038 Genasun Solar Charge Controller is green
(blinking indicates it is charging, constantly on indicates charge is full),
see A.5.3 "PSA038 Genasun Solar Charge Controller" on page A-5.
If there is no light, ensure the battery is properly installed and the
system is turned on.
CAUTION The yellow
connector does not
connect in the power
block. Do not attempt to
connect the yellow
connector to a red or black
connector.
NMS044 Reference Manual Configure the RV50 Gateway 2-3
2.3 Configure the RV50 Gateway
The RV50 gateway requires a SIM card for access and service.
TAKE NOTE The NMS044 does
not regulate data usage.
When purchasing a SIM card, you will need:
• Adequate data plan. Significant charges may occur if the plan is
exceeded.
• Do not need messaging/voice on the plan
• Public IP address
TAKE NOTE Cellular providers
may block incoming
connection requests to a SIM
with a dynamic IP address.
Check with the cellular
provider to assure that
incoming connection
requests are allowed.
• A public IP address is needed in order to connect
remotely with the 831C. If the plan does not have a
public IP address you will not be able to access and
control the system.
• A static IP address or alternative dynamic IP with
Dynamic Domain Name Service (DDNS) as an alternative
can be used, however with this option you can not
remotely access the system. You will still be able to
upload files to SFTP or Dropbox.
•APN
• Request the APN from your cellular provider. You will
need this to configure for remote use.
2.3.1 Install SIM Card
With system powered off, install the SIM card by following these steps:
LEARN MORE To learn more
about the RV50 gateway, refer
to the Sierra Wireless website.
Step 1 Using the provided #2 Phillips head screw driver, unscrew
the two screws located on the RV50, disconnecting the
gateway from the case plate.
