9.671 Tandberg-RX8200-TriBand-SNMP

This page describes the device driver and the device window for Tandberg RX8200 DVB-S2 / HDTV IRD, controlled via SNMP.

This is a special version with support for TriBand LNBs.

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 the conditional access parameters. See also the remark about RAS and BISS keys below.
• --- Contains the parameters concerning the video decoding end video test output.
• --- Contains the parameters concerning the audio outputs and the selection of the audio signals from the MPEG stream. Unlike with other IRD drivers this page also controls the SDI embedded audio assignments.
• --- 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 RX8200.

• 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.

• loFreqMid --- The LO frequency for the middle 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.

• bandEdgeLow --- Below this frequency, the low LO frequency will be selected.

• bandEdgeMid --- Below this frequency (and above bandEdgeLow), the middle LO frequency will be selected.

• spectrumSense --- Controls the spectrum inversion setting of the IRD. AUTO should work in most cases (switches to NORMAL for Ku-band LO Frequencies, INVERTED for C-band frequencies).

• serviceHunt --- If set to ON, the IRD receives the first available program in a stream when tuned to a new signal. With OFF, the IRD insists in receiving the service ID / PIDs which were set before. For SNG hub applications you will usually select ON, for distribution / relaying applications OFF.

• 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.

Remarks

The RX8200 provides wide functions to monitor the state and control the assignment of SDI embedded audio streams. To present these functions clearly layed out, the embedded audio parameters have been moved to the audio page with this IRD.
