Configuring the dvb adapter

This article describes how to configure the DVB adapter in the Astra web interface

Open the Astra web interface. In the upper right corner - find the item "New Adapter". When you click it - you will open a new window-in which you will be asked to add an adapter.



A description of the fields:

Lets configure our DVB-S2 adapter: input the frequency, polarization and symbol rate. For example, for 36E-is 12091,90:R:27500


and go to the tab


###LNB parameters (heterodyne frequency) Default: LOF1 - 9750 MHz, LOF2 - 10600 MHz, SLOF - 11700 MHz For circular polarized converters (e.g. 36°E, 56°E), it is necessary to set the value 10750 MHz in all fields


Voltage 13/18 Volts are not only the supply voltage but also the switching signals of polarization. 13 V is the horizontal h (left L) switching signal in the range of 11-14 Volts, and 18 V is the vertical V (right R) switching signal in the range of 16-20 Volts The 22 kHz signal is a sub-band switching signal. When 22 kHz is on, the upper band (High Band) is taken and in the absence of this signal, the lower band (Low Band) is taken respectively. In case of universal Converter this option is not active, the selection is made automatically depending on the selected frequency. В нашем случае - для 36E нам нужно установить значение 10750 во всех полях.


and go to the tab

DiSEqC - Digital Satellite Equipment Control



In our case - DiSEqC is not used and we will go to the next tab:

Unicable - Protocol that allows multiple tuners to be connected to the same cable


UNICABLE SLOT - Default: unicable disabled possible value: 1 - 9 SLOT POSITION - possible value: A, B SLOT FREQUENCY - possible value: 950 - 2150 MHz

In our case - Unicable is not used and we will go to the next tab:


MODULATION Default: Auto Default now for DVB-S - QPSK, DVB-S2 - PSK8 FEC - forward error correction Default: Auto (by default) ROLL-OFF - spectrum efficiency. used for DVB-S2 only, possible value: Default: 35, 25, 20, AUTO

TIMEOUT - delay in seconds to DVR error checking, default 2 seconds DDCI - bind the adapter to DVB-CI Digital Devices. The value corresponds to the adapter number on the system Budget Mode. Disable hardware PID filtering - disable hardware filtering of the data. Astra will get all the stream from the DVB adapter. The parameter is used to transmit the entire transponder or for legacy DVB adapters without hardware filtering (e.g. SkyStar 2). By default, hardware filtering is enabled Signal in dBm - output signal level in dBm. For adapters TBS, the driver parameter must be set to esno=1 in the file /etc/modprobe.d/tbsfe.conf. DVB adapters with demodulator CXD2820R transmit the value of the signal level in dBm by default Scale DD MaxS8 SNR - correction of signal level display for DD MaxS8 adapters CA DELAY - delay, in seconds, before sending channel information to the conditional access module


In our case - none of the parameters we need - and we click on the button at the bottom " SCAN"

If everything is set up correctly-we will have the signal level and in a few seconds-a list of available channels.


Setting the "checkbox" next to the desired channels at the bottom press the button "APPLY" Image
