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 Rev E 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 RV50X 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
When you receive the NMS044 system you will need to perform several “first use”
procedures. While most can be done in the field or after deployment, we highly
recommended completing this section before deploying.
TAKE NOTE This module assumes that you have the complete NMS044 and all its components. The
setup is similar for the EPS044, and the following modules apply to that system as well.
2.2 Preparing the Battery
In this section:
• 2.2.1 Installing the Battery
• 2.2.2 Charging the Battery
2.2.1 Installing the Battery
TAKE NOTE Connect all wires and devices prior to turning on the system.
Step 1 Open the case and lift out the plate being careful not to pull any
wires loose. Set on an angle away from case.
Step 1 If not already in place, insert the battery (BAT019 or BAT020) in the
case inside the guide lines, with the terminal toward the 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.
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 Charging the Battery
We recommended that you charge the battery prior to deployment
using the included PSA039 AC Battery Charger.
Step 1 Connect the solar connectors together, and use the plug to
connect to an external power source (wall outlet) until
charged.
TAKE NOTE You will know it is fully charged when the PSA038 Genasun Solar Charge Controller LED is
green (Blinking indicates charging, Solid green indicates charge is full). If there is no light,
ensure the battery is properly installed and the system is turned on. For more
information, see A.5.3 "PSA038 Genasun Solar Charge Controller" on page A-5.
2.3 Obtaining Cellular Service for the RV50X
The RV50X gateway requires a data plan, SIM card, public IP address,
and an APN for access and service.
Step 1 Purchase a SIM card with the following features:
• A data plan sufficient to the NMS044 data usage. The NMS044
does not regulate data use. Significant charges may occur if the
plan is exceeded.
• No messaging/voice data is needed.
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 Rev E Obtaining Cellular Service for the RV50X 2-3
Step 2 The cellular plan must support a public IP address so that
you can access and control the system remotely. (Often
cellular providers 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.
•If the plan does not have a public IP address you will not
be able to access and control the system. However, you
can still upload files to SFTP or Dropbox using a static IP
address or alternative dynamic IP with Dynamic Domain
Name Service (DDNS) as an alternative.
Step 3 Request the APN from your cellular provider. You will need
this to configure your system for remote use.
LEARN MORE To learn more about the RV50X gateway, refer to www.SierraWireless.com.
2.3.1 Installing the SIM Card
With the system powered off, install the SIM card by following these
steps:
Step 1 Using the provided #2 Phillips head screw driver, remove
the 2 screws located on the RV50X, disconnecting the
gateway from the case plate.
