### 2.1. Saved Objects

Saved Objects is the connection and authorization setting for connection to the data concentrator stored in the permanent memory of the PC. This data is shared both for the
ND Prepaid software and for the Matilda Conf software. To prevent unauthorized access to the saved settings, access to this data when the program is started is blocked.

### 2.1.1. Access to Saved Objects

Locking Access to Saved Objects at Startup protects your saved settings from unauthorized access. By default, the password is not set. You can change the password through the appropriate item in the menu.
To unlock:
1. enter password;
2. press "Unlock Saved Objects".
If successful, the table will show the list of saved objects.
When blocked Saved Objects are allowed to search for devices on a local area network (Scan LAN), execute authorization with dataconcentrator, but you are not allowed to use Local Connection.

### 2.1.2. Operations with Saved Objects

With saved objects from the list, it is allowed to perform the following operations:
- change the name;
- delete;
- copy/paste (as setting), copying as plain text;
- export to file.
The above operations are performed through the context menu (right-click).
To quickly fill out the connection and authorization settings, from the list of objects, you need to click once on the desired object with the left mouse button once. If you double-click: the process of connecting to the data concentrator will start.

### 2.2. Authorization

Для доступу до збережених даних/налаштуваннь концентратора необхідно спочатку виконати авторизацію.
В концентраторі передбачено 3 рівні доступу:
- гість - дозволено читання всіх параметрів, запис заборонено;
- оператор - дозволено читання всіх параметрів, дозволено лише параметрів, що відповідають за опитування пристроїв (керування пристроями) в мережі ZigBee ;
- адміністратор - дозволено читання/запис всіх параметрів і оновлення внутрішнього ПЗ.
Якщо з одної IP адреси буде виконано більше 10 невдалих спроб авторизації, то цей IP буде занесено до списку блокування. Алгоритм блокування передбачає блокування доступу від 20 до 60 хвилин в залежності від кількості спроб авторизації.
Довжина тексту в полях Логін і Пароль обмежена в 200 символів. Підтримуються лише друковані символи з набору UTF-8 (ISO/IEC 10646).
Якщо відмітити "Додати до Збережених Об'єктів", то при успішній авторизації налаштування для з'єднання будуть додані до Збержених Об'єктів.

### 2.3. Connection settings

This software supports the use of various communication channels. All of them are described below.

### 2.3.1. Direct Connection

Direct connection (without intermediaries) with a data center concentrator over TCP/IP.
To use this type of connection, it is necessary for the dataconcentrator to be assigned an IP address. The following condition should also apply: the PC from which the connection will be initiated must be in the same network with the dataconcentrator or be able to connect through other network equipment if located on different networks (NAT settings, firewall, etc.).
By default, the TCP server on the data concentrator listens to port 9090 on all network interfaces using both IPv4 and IPv6 stacks.
The remote service address can be:
- IPv4 address
- IPv6 address
- Domain name
A local network scan tool is provided for fast LAN searches (see paragraph 2.1.4)
If the authorization is successful, a list of meters will open. The list of meters is automatically obtained from the dataconcentrator after the authorization, in addition it can be updated manually.

### 2.3.2. MAC

Connection via M2M Service. Each dataconcentrators connects to the specified M2M Services and passes them their MAC addresses and Object Name.
Correspondingly, knowing either the Object Name or one of the MAC addresses can create a connection to the dataconcentrator through the M2M Service.
By default, the following M2M Services addresses are used:
svaha.ddns.net;
svaha2.ddns.net;
in both cases the port 65000 is used.
So to connect using the MAC profile you need:
Fill Object Name or MAC and mark the corresponding Connection Mode.
Fill in the M2M Service Address field
Set the M2M Service Port
Specify time Waiting for connection, For slow connections (such as GPRS) it is recommended to use a time of at least 20 seconds.
A local network scan tool is provided for fast LAN searches (see paragraph 2.1.4)
If the authorization is successful, a list of meters will open. The list of meters is automatically obtained from the dataconcentrator after the authorization, in addition it can be updated manually.

### 2.3.3. Local Connection

Local Connection is a type of connection that can be exchanged through:
- ZigBee coordinator directly connected to the PC
;
- Tcp/ZigBee Gateway.
.
In both cases, in order to start using the objects, it is necessary that the Saved Objects be unlocked.
By clicking on OK, a preventive check of the possibility of using a given communication channel is performed. If the check is done, then the switch to the list of meters will take place.
The list of meters supporting prepaid is tightened automatically from the software "KTS Intek Radio Collect", in addition it can be updated manually.

### 2.3.4. Scan LAN

The LAN scanner helps you quickly find the included dataconcentrators that are plugged into the same local network as the PC. The function of the scanner includes getting Object Name (Object ID), IP and MAC of dataconcentrator.
Additionally, it is possible to check the availability of the specified IP in the network you are using. This is especially true if the dataconcentrator works on multiple networks simultaneously (Ethernet/GPRS-EDGE-HSPA/USB-Ethernet). But using this mode can block your IP hub, for a period of 20 minutes to several hours.
To transfer the connection settings of the selected dataconcentrator, you must:
- In Import select which connection type will be used, if Direct Connection, then select Import IP if MAC - Import MAC.
- Select the row in the table and click OK or double-click on the required line.
On some operating systems, you may need to allow network access. This usually only asks once, after the user allows the network to be used, repeat the scan by clicking Scan.
Search results may be false if a router that manages a local burglar blocks UDP packets.
