1Introduction
represents the natural development of the already known and reliable TMF series of NESA
dataloggers, with a product equipped with the most modern data acquisition technologies that combines the
highest level of performance with improved and complete ease of use. A modular open datalogger with very
high precision, equipped with a Linux, web server Apache and PhP interpreter operating system, , usable and
configurable via the web without the need for any external or proprietary software.
contains all the computing power of an ARM®32 bit processor, managed across the knowledge of
over twenty years of experience in Linux Embedded operating systems, and with a high technical ability in
processing, calculation and data processing methodologies and algorithms.
has a superior ability to acquire signals in a practically unlimited number of I/O and has different
types of memory for the protection of data or copies of them, managed at different levels of security.
offers transmission and data transmission functions that allow the use of all modern broadcast
channels (modem, radio, mobile phone network, satellites, copper or fibre cable, etc.), also in redundancy
between them (transmission redundancy); it makes available most of the widespread protocols between
information sharing systems, for example RS232, RS485, Modbus, TCP-IP, SMTP, FTP, Socket TCP, SDI12, SNP
and many others. The structure of the stored and / or transmitted record or data track offers a wide range of
customisation, starting from the simple structure of the Nesa, being able to change in the sequences and
contents, as well as in the separation characters.
Finally, has an innovative user management system, dividing them between master user and
normal user, allowing the sharing of machine resources, while creating different configurations for the user as
if they were different dataloggers. In this manual a specific section is dedicated to the topic.
On-board software is multilingual with possibility of choice.

1.2 First start-up
Before connecting the datalogger, make sure that the power button is in the 0 (Off) position.
Connect the power supply to the datalogger through the special 6-pole connector, using a battery (12Vdc
minimum 1A / h), or a 220Vac/12Vdc wall power supply according to the following procedure:
a) If you have battery-only, connect its terminals to the +12Batt and Gnd inputs.
b) If you only have a wall power supply unit , connect the terminals to the +12Batt and Gnd inputs.
c) If you have a wall-mounted power supply unit + battery, connect the battery terminals to the +12Batt
and Gnd inputs, and the power supply unit to the InPS and Gnd inputs. In this configuration the battery
is automatically recharged (max. charging current 5A) from the datalogger.
NOTE: As the datalogger has an internal battery charger, the supply voltage from external power supply should
be at least 13.5-13.8Vdc.
Turn the power button to the 1 (ON) position.
In this phase it is possible, through the sequence of the status LEDs, to verify the correct ignition of the machine.
In particular:
1. When the power button is set to ON the LED A is on.
2. Depending on the type of power supply (battery, or battery plus panel or battery + power supply) the
LEDs Aand Bwill light up, which remain lit to signal the presence of the power source. In particular LED
B will only be on if there is battery connected and charging.
3. The Cand Dstatus LEDs are normally off, only flashing if there is an anomaly in the system start-up
phase, signalling an operating system kernel anomaly.

The ignition sequence is also shown in the display, where the machine starts and diagnostics messages appear
(see paragraph 9); of these the first one represents the serial number of the datalogger.
The entire start-up sequence of the datalogger takes approximately 90 seconds.
Once the start-up is complete, the datalogger starts the standard acquisition cycle and the display of the
instantaneous data in the display has the following form:
* For decoding see appendix A and B
The measurements are displayed cyclically at intervals of approximately 2 seconds, passing from one
measurement to another depending on the configuration of the machine.
1.3 Connection to the datalogger
The datalogger can be immediately connected to a computer, laptop or PDA, through the Lan network interface.
It leaves the factory with a pre-set IP address, and subsequently modifiable, to which reference must be made
for connection.
LAN interface:
IP:
192.168.1.115
Subnet mask:
255.255.255.0
To connect to the machine it is necessary to use the supplied Ethernet cable or any
cross (cross) type cable following the procedure below:
1. Leave the datalogger on or switch it on.
2. Connect the cable to the LAN port of your computer.

3. Connect the other end of the cable to the datalogger Ethernet port.
4. Turn on the computer and set an IP address of your network card congruent with that of the datalogger,
for example 192.168.1.10 and subnet mask 255.255.255.0.
At this point the connection between computer and is established and it is possible to access
configuration pages or data visualization pages as explained in the next paragraphs.
NOTE: The data logger gets off the connection from browser after 30 minutes if there aren't any input from user.
This time interval depends on the Browser used.

2Web interface
To access the configuration and/or display data page of the machine, it is sufficient, after establishing the
connection as in the previous paragraph, to open one of the following Internet browsers for which the
datalogger is compatible:
✓Chrome (of Version 63.0.3239.132)
✓Firefox (of 57.0.4)
✓Edge (of 41.16)
The configuration procedure of an terminal only takes place through the use of web pages, while
the display of data is also possible on the display.
For correct display of the pages, enable javascript scripts and the option to search the most recent versions of
the stored pages in the tools or options menu of each browser
With the browser active, type in the address bar the IP of the datalogger: http://192.168.1.115 (factory address)
and wait for opening of the main page that allows the general user to choose between viewing the instantaneous
data and configuring the datalogger.
