INSTALLATION

The box can be placed on the floor, on the four support feet, or fixed to a wall or
36 ÷ 52 mm diameter mast.
To install the station, proceed as follows:

•

In the case of a fixed installation on a mast/tripod, place the mast/tripod in the in-
stallation site. For mounting the HD2005.20.1 tripod, see par. 4.1. If the mast/tripod

is rather heigh, bracing is advisable (HD2003.74, HD2003.75K and HD2003.78K op-
tional accessories are available).

•

Fix the supports of the housing to the wall or mast/tripod (in the case of a fixed in-

stallation) and hook the housing to the supports (see par. 4.2).

•

In the case of power supply from a solar panel, install the panel (see par. 4.3).

•

Screw the microphone unit on the VTRAP4M extensible stand, in the case of mobile

installation, or on the top of the mast/tripod, in the case of fixed installation (see
par. 4.4).

•

Place the 3G antenna on the housing (see par. 4.6).

•

Connect the antenna, the microphone unit, the external power supply (only for
models with power supply from solar panel or 24 V

source) any other optional ex-

ternal devices (meteorological sensors, alarm indicators, …). For the connections see

par. 4.5.

•

Insert the SIM and configure the APN as described in par. 4.7.

•

Set the sound level meter serial in RS232 mode and baud rate 115200 (see the in-
structions of the sound level meter).

•

The station can be switched on and off by using the ON/OFF switch. Afetr switching
on, wait for the functional check and the initial automatic configuration with the
server to be completed. During the functional check, the sound level meter is

switched on for a couple of minutes and then switched off after the server has rec-
ognized the station. At the end, the NETWORK CONNECTION LED must light up. If
the sound level meter remains on and the NETWORK CONNECTION LED remains off

after the initial phase, it means there are network problems or the station has not
been recognized by the server.

CONFIGURATION OF THE STATION:

After the station is operational and connected to the network, all the operating pa-
rameters of the station can be configured via PC by using the "Monitor" module (oper-
ating with a hardware key) of the Noise Studio software. For the details on the con-

figuration of the station, please see the instructions of the software.
The "Monitor" module allows managing either a single station or networks of noise
monitoring terminals.
The measurements can be stored in folders ordered by date, in a reserved area on the

Delta OHM Storage Server or on any other FTP server. The HD2011NMT station sends
periodically the measurements to the user-selected storage area. Measurement files
can be viewed with the "Monitor" module and analyzed with the other Noise Studio

application modules.
The interval with which the station sends the data (default 5 minutes) can be changed,
as well as with the "Monitor" module of the Noise Studio software, also by sending to
