9.542 Qbit-Q572-AudioReceiver

This page describes the Qbit-Q572-AudioReceiver device driver and its device window. The Qbit-Q572-AudioReceiver device driver monitors and controls the audio satellite receiver.

The driver automatically recognizes the number of licensed audio decoders within tghe unit. It is prepared to support up to 4 decoders within a single unit.

The driver was tested with the following models:

• Model: Q572 V2.247d (D4 DVBS2 L2 AAC LPCM TS)
• Build: 20190606-114014 SVN:35845_20180920-095639
• Control: 17.12.2015 20:03 1.463.051 ctrl_v01_16.xsvf
• Stream: 14.11.2016 11:35 1.462.932 stream_v01_19.xsv
• Codec: 14.11.2016 11:35 1.462.932 codec_v01_14.xsvf

Device window pages

The following table shows which device window pages are available with this individual device type. Tool-bar functions not mentioned here are described at the general description of device windows .

• --- The RF monitoring and control parameters.
• --- The audio decoder output monitoring and control parameters.
• --- The faults page.
• --- The device info page.
• --- The maintenance page. The configuration parameters described below are set at this page.

Configuration parameters

At the maintenance page of the device window there are a couple of configuration parameters which must be set to make the software talk to the device.

• parameter --- description

• address --- The SNMP address specification for the device. The full address specification consists of the following fields:aaa.bbb.ccc.ddd:pppp read-community write-community

  • aaa.bbb.ccc.ddd --- The IP address of the device in 'dotted quad' notation. This field is mandatory.
  • pppp --- The IP port number where the device accepts SNMP requests. The port number may be omitted, the driver uses the standard port 161 in this case.
  • read-community --- The SNMP read community name. This must match the read community expected by the device.
  • write-community --- The SNMP write community name. This must match the write community expected by the device. The write community name may be omitted, the driver uses the read community name for both, read and write in this case. If both community names are missing, the driver uses 'public' as a default for read and write community.

• readBackDelay --- Defines the delay the driver uses when it reads back parameters recently commanded. The delay is initialized at a proved preset value which should not be changed under normal circumstances.

• audio.1-4.limitLow --- Sets the silence detection level alarm threshold for decoder 1-4

• audio.1-4.limitHigh --- Sets the overload level alarm threshold for decoder 1-4

• audio.1-4.lowT1 --- Sets the silence detection level limit alarm raise delay.

• audio.1-4.highT1 --- Sets the overload level alarm raise delay.

• audio.1-4.lowT2 --- Sets the silence detection level clear delay.

• audio.1-4.highT2 --- Sets the overload detection level clear delay.

• loFreqLow --- The LO frequency for the low frequency band. The software sets the appropriate LO frequency every time before it changes the receive frequency.

• loFreqHigh --- The LO frequency for the high frequency band. The software sets the appropriate LO frequency every time before it changes the receive frequency.

• bandEdge --- The frequency where the software switches the LO frequencies.

• lnbPolSwitch --- If you set this parameter to ON, the 'lnbVoltage' parameter below becomes read-only and the LNB voltage is controlled though the 'polarization' parameter of the device driver (only makes sense with lnbPower=ON).

• lnbVoltage --- Selects if the IRD shall apply LNB power to the input as well as the voltage level.

• 22kHzAuto --- If set to ON, the driver switches the 22 kHz tone depending on the receive frequency. Frequencies above the 'bandEdge' value cause the 22kHz tone to be switched on, lower frequencies switch the tone off. The 22kHzAuto mode overwrites the the '22kHz' setting described above.

• 22kHz --- Makes the IRD apply a 22 kHz tone to the LNB power when set to ON.

• deviceComment --- An optional text entered here appears as an addition to the tooltip which is shown while the mouse is placed over a device icon in the GUI. The "\n" character sequence is translated into a newline character, splitting the text into multiple lines.
