DECRO Advanced 4 solution (New generation): composition, installation and connection
This
article explains what the new generation of ADVANCED DECRO solution
(ADV4) is, and provides instructions on how to install and connect
it to the user's laptop.
This new
system consists of an ACQUISITION UNIT x4 (ACQ4) coupled to an ANALYSIS SERVER (SRV).
It reduces its size while maintaining performance and increasing analysis and
connection flexibility.
1. ADV4 solution – Introduction about the solution
The new
ADV4 is a lightweight data ACQUISITION UNIT designed specifically for signal
recording, coupled with an ANALYSIS SERVER. The two components communicate with
each other, but each has its own role to play.
If you
have the older generation, please refer to the FOLLOWING ARTCILE (The older ADV is
packaged in a flight case, allowing for a plug and play operation with
only one power supply and network cable connection required)
Unlike
other systems, the ACQ4 does not include any tools for analysing data.
Its role is to acquire data by being placed in the animal facility alongside
the subjects.
With this acquisition
unit, you can capture and record signals in real time, have access to a preview
of the signal after the data acquisition to check its quality and automatically
send the data to the ANALYSIS SERVER, with no extra steps.
Once the
data is in the ANALYSIS SERVER, you can use the full LASA software to explore,
analyse and export your data. The analysis server can be located directly in
the animal facility or in a room connected to the internal network. For its
part, the analysis server has no acquisition capacity,
even if it is
physically on site.
The
dissociation of the two main functions: Acquisition and Analysis allows the
user to analyse data while acquisitions are in progress, without the risk of
losing data, therefore saving time.
Installation
and connection options are summarized here:
> the
acquisition unit communicates directly with the server via a cable and is used
locally in the animal house. (TOP)
> the
acquisition unit and the analysis server communicate via the internal network
and can be placed in two different rooms. (BOTTOM)
2. Acquisition unit – Installation
In order to
access the software and perform an acquisition, it is necessary to
install and connect the acquisition unit. Here are some steps to follow:
1- First, put your unit in the
same room of the animals, and avoid elements that may interfere with the Bluetooth
signal, such as a metal partition or thick wall.
2- Do not forget to screw the
antennas on the adequate supports. The 4 antennas must be positioned at 45° as
shown in the photo below.
3- Link the power cable and plug
it in an electrical socket nearby. The start button 
then
lights up BLUE, if the server does not directly power
on, click on the corresponding button.
Starting up
this type of system may take a few minutes (~5 min). Please wait before
attempting to connect. The system is fully powered on when the blue light
is steady.
4- Choose the desired connection
mode according to your needs.
>
Locally, by connecting it directly to a PC (LAN1 to PC)
allowing only one computer to have direct access to the ACQ in the animal
facility,
In this
mode, even if your computer is connected to the internal network, the
acquisition can only be used locally. Consequently, data analysis must
be carried out locally: this involves connecting the analysis server by cable,
enabling direct data transfer and automatic synchronisation between the ACQ and
the SRV, without any intermediate steps (exporting, downloading and
importing files from the ACQ to the SRV).
> Or to your network (LAN 2 to NET) allowing the ACQ and SRV to
communicate over the internal network and access the ACQ and the SRV server
from any company computer.
Please contact your IT department to define the names/ IP addresses of the
various elements on your network and open the corresponding ports. Please refer
to this section for details of the ports to be opened.
This
connection mode enables remote access to any element
if the laptop is connected to
your network and direct data transfer and automatic synchronisation between
the ACQ and the SRV, without any intermediate
steps (exporting, downloading and importing files from the ACQ to the SRV).
5- Connect the Ethernet cable to
the appropriate port, depending on your setup: LAN1 to PC or LAN 2 to NET. Once
these steps are complete, you can connect to the acquisition software.
3. Analysis server – Installation
In order to
access the software and perform data analysis and export, it is
necessary to install and connect the server. Here are some steps to follow:
1- Choose where to place your
server and the desired connection mode according to your needs.
> Locally,
by connecting it to the acquisition unit (LAN1 to PC/ACQ) allowing
only one computer to have direct access to the two elements in the animal
facility,
> Or to your network (LAN
2 to NET) allowing the two elements to communicate over the network and
access the server from any computer.
Please contact your IT department to define the names/ IP addresses of the
various elements on your network and open the corresponding ports. Please refer
to this section for details of the ports to be opened.
2- Connect the Ethernet cable to the
appropriate port:
3- Link the power cable and plug
it in an electrical socket nearby. The start on/off button then lights
up BLUE, if the server does not directly power on, click on
the corresponding button.
Starting up
this type of system may take a few minutes (~5 min). Please wait before
attempting to connect. The system is fully powered on when the blue light
is steady.
Once these
steps are complete, you can connect to the analysis server software.
4. ADV4 solution – Connection instructions
Once the
acquisition unit and the analysis server have been correctly installed and
connected, you can connect to both elements using the same process
The access
is made through a web browser. Browsers compatibility is indicated in the
following table.
Each
element and connection mode has its own URL and IP address, which you can find
on the label of your acquisition unit, USB adapter or analysis server.
Enter the
previous addresses in the search bar to connect
When you
first connect, your browser may display an alert because it does not recognise
the system as a ‘reassuring website’. Simply click on ‘advanced settings’ and
‘continue to the site’.
The
connection is established between your computer and one of the elements when
the ETISENSE logo appears. On the connection’s page, click on the "CONNECT"
button to access the system. The connection may take a few seconds if you have
just switched on the system. If it doesn't work, check that your system is
properly connected and/or that the Ethernet cable is correctly inserted in the
right port depending on the configuration.
A User
Authentication and permission module (UAP) is installed on the system. The
welcome page requires an email and a password to proceed...
default login
credentials are configured on the system.
Login =
ACQ: acq-nano-00XXX.admin@etisense.com and SRV: adv-srv-00XXX.admin@etisense.com
Password = decroAdmin
authentication mode = LOCAL
For
security reasons, the user must use it for the first connection, then create an
administrator account and deactivate this account.
Please refer to these steps to disable the default administrator account:
Once the
connection succeeded, you will gain access to this page:
Note also that
the homepage banner differs between the ACQ and the SRV, as well as the design
of the data transfer button.
Acquisition unit header:
Analysis
server header:
Please
note that once connected
- A loading
wheel on the ACQUISITION button of each study may be present as well as a
notification at the bottom left of the page. This information is present to
specify that the acquisition slots are being activated one by one and that you
must wait for the complete start-up before recording.
- To align
the system over time, a pop-up window may appear offering to align the system
over time after the slots have been started. Be aware that realigning the
clocks of each slot may take some time, but it is necessary. Wait for the
update wheel to disappear.
You can
open both the acquisition unit interface and the analysis server interface on
the same Laptop. Each will have its own browser tab :
5. ADV4 solution – Default Network Ports (LAN2)
To enable
the acquisition unit and the analysis server to be networked and send data to
each other (LAN2), you must check with your IT department that the following
ports are open
- Port 443 (HTTPS)
- Port 22 (SSH - rsync)
These ports must be opened on the acquisition unit and on the analysis server.
If the acquisition system communicates with the analysis server via a wired connection (Direct mode), simply check that the ethernet cable is connected to the correct ports on both systems.
If the acquisition system communicates with the analysis server via a wired connection (Direct mode), simply check that the ethernet cable is connected to the correct ports on both systems.
Even if the previous ports have been opened, it is possible that some internal firewalls prevent the two systems from being paired. If this is the case, please contact your IT department. We will be happy to answer any questions you may have.
6. ADV4 solution – Pairing and data transfer between ACQ and SRV
The pairing
of the two elements is not initially configured as it depends on the setup
configuration. To do this, from the ACQ, click on the data transfer button (see
below) to access the configuration interface.
A form
called ‘Pair to ... ’ should appear. It contains the following fields:
To combine the two elements, you need :
- Enter the login used to enter the analysis server. As before, you can use the default identifiers (Default login = adv-srv-00XXX.admin@etisense.com)
- the associated password (default password= decroAdmin)
- and the connection url depending on the setup configuration.
o LAN 1 = URL ou IP adresses on the serveur label
o LAN 2 = URL of the system given by IT on the internal network
Once
validated, this information enables the ACQ to connect to the SRV. Once the two
elements are linked, this page appears:
If pairing
with the SRV fails, the ‘Retry’ button can be used to restart the
connection attempt.
If you would like to know more about data transfer, please refer to this article.
To dissociate the two elements, simply click on the information button on your storage space:
And click on UNPAIR.
7. ADV4 solution – Powering off from the software
We
recommend that you power off the both elements by following this
procedure:
> Click on the gear icon located in the top right corner of the header
> Click
on the “SHUT DOWN” button on the settings popup that appears
Allow the
system to shut down completely (all power diodes should turn off within a few
minutes).
