1.434 NTT-HVD6100

This page describes the device driver and the device window for the NTT HVD6100 IRD with support for RF input (DVB-S/S2), ASI input and IP input.

Device window pages

The following table shows which device window pages are available with this individual device type.

• --- The main receive parameters, including frequency and service selection.
• --- IP parameters
• --- The conditional access parameters
• --- The video parameters
• --- The audio parameters
• --- Faults and fault mask
• --- The device info page.
• --- The maintenance 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 encoder.

• 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.

The read/write-community strings may be set through the front panel or the web interface of the device. Factory defaults are 'public' for the read community, 'private' for the write community. Hence a typical address specification for a NTT-HVD6100 may be 10.0.0.1 public private.

• readBackDelay --- Defines the delay the driver uses when it reads back parameters recently commanded. The delay is initialized to a proved preset value which should not be changed under normal circumstances.
• 22kHz --- Turns the 22 kHz signal in the LNB supply on or off. Only effective if 22kHzAuto is set OFF.
• 22kHzAuto --- Switching this on, makes the driver controlling the 22kHz signal with the receive frequency. For frequencies above the "band edge" 22kHz gets switched on.
• lnbPower --- Switches the LNB power supply ON or OFF.
• lnbVoltage --- Selects the LNB voltage (13V/18V) or switches it OFF. Only effective if the "lnbPolSwitch" parameter is set OFF.
• lnbPolSwitch --- Selects if the LNB voltage shall be permanently set to the the value selected by "lnbVoltage" (OFF) or if the voltage shall be selected from the "polarization" parameter of the driver.
• loFreqHigh --- The high band LO frequency.
• loFreqLow --- The low band LO frequency.
• bandEdge --- The band edge frequency.
• marginThreshold --- If "state.margin" drops below this value, a "Margin" fault is generated.
• serviceHunt --- Setting this ON lets the receiver use the first available service when receiving a new signal. OFF forces the receiver to get the service with the service ID set.
• 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.
