1.60 Ateme-DR8400

This page describes the device driver and the device window for the Ateme DR8400 IRD, controlled via SNMP.

The Ateme IRD handles PID selection in another way than other IRDs. See paragraph "PID selection" for more information about this.

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 .

• --- Contains the main receiver settings and status display.
• --- Contains IP in / out parameters
• --- Contains the conditional access (BISS) parameters.
• --- Contains the parameters concerning the video decoding.
• --- Contains the parameters concerning the audio outputs and the selection of the audio signals from the MPEG stream.
• --- Contains the parameters concerning the ASI / SDI output ports of the device
• --- 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 DR8400.

• 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.

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

• 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.

• lnbPower --- Selects if the IRD shall apply LNB power to the input.

• lnbVoltage --- Selects the LNB power supply voltage (13V/18V). This switches the polarization (13V=Vertical) with some LNBs.

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

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

• loFreqLow --- The LO frequency for the low 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.

• marginThreshold --- Defines the minimum s/n margin value the driver accepts as OK. s/n margin values below this threshold raise an "Margin" fault (faults.30). The margin fault detection is done by the sat-nms device driver, not by the device itself. Hence, the margin value ist stored as a saved parameter on the VLC rather than as a parameter in the IRD.

• marginOffset --- Defines an offset which will be added to the margin shown to the operator.

• 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.

PID selection

The Ateme IRD does selecting a program or a certain stream from the decoded transport stream in a different way than other IRDs do. The IRD offers three basic operation modes which do PID selection a certain manner. The configuration parameter "serviceHunt" controls this mode.

• AUTOMATIC --- In AUTOMATIC mode, the IRD automatically selects the first program in a transport stream and assigns the audio streams belonging to this program to the audio outputs one by one. The first audio stream is sent to the first embedded SDI audio and in parallel to the first AES audio output, the other audio streams are arranged accordingly. You cannot change the selected program or the audio assignments in this mode.
• AUTOSERVICE --- In AUTOSERVICE mode, the IRD tries to select the program / service which has been selected previously. No signal is output if the selected service ID is not present in the transport stream. You may select any program from the transport stream by double clicking the service name in the list on the first device window page in this mode. The audio streams for this service are selected and arranged automatically in the sam way as in AUTOMATIC mode, there is no way to change this assignment.
• PIDLOCKED --- In this mode, all decoded streams are selected manually by PID. This applies also to the video stream which only may be selected by PID in this mode, not by selecting a service. Audio streams may be selected freely by PID and arranged to the audio outputs.
