OPERATING ENVIRONMENT RECOMMENDATIONS

For the normal and reliable operation of the DB8000 device we recommend to follow the next

list of instructions:

• Please, install the unit only in places with good air conditioning. The unit has been designed
for operation within an ambient temperature range extending from 10 to 60°C. But because

adjacent, less efcient equipment may radiate substantial second-hand heat, be sure that the
equipment rack is adequately ventilated to keep its internal temperature below the specied

maximum ambient temperature.

• We do not recommend installation in rooms with high humidity, dusty places or other
aggressive conditions.

• Although it is expected that DB8000 will be installed close to exciters (or transmitters of
even higher-power!), please practice reasonable care and common sense in locating the unit

away from abnormally high RF elds.

• Please, use only already checked power supply cables and sources. The shielded cables

usage is strongly recommended.

• We strongly recommend connecting the device only to reliable power supply sources.

• In case of unstable power supply, please use UPS (Uninterruptible Power Supply).

• Please, use the device only with placed top cover to avoid any electromagnetic anomalies

which may cause problems of the normal functionality of the unit.

• Please, connect DB8000 only to good quality Internet connection. This is very important for
the normal remote operation of the unit.

• Please, check if your network settings pass through all the data trafc required for the

normal operation of DB8000 unit.

SILENCE DETECTOR SETTINGS

The Silence Detector is to watch the levels of the signals applied at the DB8000’s Inputs. The
Input Signal will be changed over from the Main Input to some of the Alternative Signal Sources

as dened by Priority Settings. Levels of the parameters affecting Silence Detector performance
are User denable and these parameters are as follows:

- Threshold Level (in dB)

- Action Delay (in seconds)

- Release Delay (in seconds)

Whenever the Main Input Signal drops below the Threshold Level an Action Delay Timer will
be activated. Signal from the next Backup Source with the highest priority will be fed to the Output
Circuit of DB8000. The last operation will be carried out only if NO signal with level above the
Threshold Level appears at the Main Input for the time of Action Delay. Before switching over

to the Alternative Source Input, availability of signal there and its level will be veried. On the

contrary – the timer will be switched back to idle state if a signal passing over the Threshold Level

appears at the Main Input before time elapsing (as dened by Action Delay). Signal presence

and signal levels of the Inputs with higher priority will be continuously monitored for the time a
Backup Signal Source is in use.

On the other hand Release Delay will be activated whenever DB8000 starts using any of the
Backup Signal Sources. Release Delay is the time to elapse before switching from Backup Signal
Source to the Main Input (in case a signal passing through Threshold Level appears there).

To perform the setting of the above three parameters please follow the next steps:

1. While in the Main Menu press the OK button;

2. Press the DOWN key and select Sub-menu 5.Silence Detector.

3. Press the OK button. The DOWN key can be used to navigate through this Sub-menu which

looks like below:

4. Using UP or DOWN keys move the cursor and select the parameter to be edited;

5. Press the OK button again and the editing eld will start blinking. Values that are needed can

be selected by UP or DOWN keys;

6. Press again OK button to conrm selection;

7. Press the LEFT key to exit to the Sub-menu or keep it pressed for more than 2 seconds to

exit to the Main Menu;

IP ROUTER AND PORT TRANSLATION

Now that broadband Internet connections are so common and NAT routers are more widespread
than ever, your connection to the Internet might be going through a NAT router or a rewall. If
you have a home network or DSL service, you’re likely to have one of these. These devices can
improve the security of your computer, and can allow a single Internet address to be shared by
more than one computer on your network.

NAT stands for network address translation and allows multiple computers or devices to access
the internet through a single internet connection and single IP address. The computers or devices
on the inside of the network, known as an intranet, are given IP addresses that are non-routable
(meaning non-internet addresses). The router translates the outgoing requests from your computer
or device into requests from the single IP address on the WAN (or Internet side of the router). On
the other hand the router will NOT forward requests originating from the outside of the network
and pass them on to the local network unless very specically congured to do so.

On the picture below is presented an example of DB8000 to router connection:

In this way, the hardware router, designed not to permit any unsolicited packets from an external

host to be delivered to an internal host acts as a router rewall and can be a problem for client

programs to reach your distant Deva Broadcast’s device.

The solution to this problem is to congure the port forwarding feature of the router to allow
certain packets to reach the Deva Broadcast’s device. Аs each make and model of router has a
different procedure for setting up port forwarding, please refer to the specic router’s manual for

guidance and further details. Usually the port forwarding can be done in the NAT section from the
router’s menu.

Required ports for Server and Client services and applications

The following list shows the ports that must be open on your router or rewall to allow specic
types of data ows through the router:

Port Description DB8000 Defaults

FTP Command Port 21
FTP Data Port 20

NOTE: If you customize the DB8000 FTP ports, please consider the same port values must be

used to congure router’s forwarding.

FTP SERVER SETTINGS

Access to the built-in FTP server is controlled by applying Username and Password with
maximum length of 6 symbols each of them. It must be noted that the FTP Server works in Passive

mode and it is necessary a Wide Area Network (WAN) address to be specied.

If DB8000 is connected directly to the computer where the FTP Client is installed then the
WAN IP Address must be equal to that of IP Address in Sub-menu 6.Network Settings
(WAN IP address = IP address). Direct DB8000 connection is illustrated below:

DB8000
WAN IP

FTP CLIENT

If a networking device (router for example) is used, then the DB8000 WAN IP Address must be
equal to that of the router as illustrated below:

NETWORK

DB8000
WAN IP

=

ROUTER

WAN IP

FTP CLIENT

Command and Data Ports are the other two parameters that must be specied in order to

establish FTP connection.

NOTE: As the DB8000’s FTP server can manage only one connection at a certain time, please

congure your FTP client to use only one simultaneous connection.
