9 Select the Roll Off factor of the incoming signal (.20, .25, .35). Set the value to .20 
or .35 when DVB-S modulation is used, and either of the three when DVB-S2 is 
used. Use a small number to reject or filter carriers close to the same frequency. 
10 Set the input signal spectrum inversion setting (IQ), which allows the operator to 
track and select inverted and non-inverted digital signals. This is normally used 
to automatically reject or filter out unwanted signals. 
When set to Auto, signal is tracked and inverted for correct selection, as 
required. When set to Opposite, the signal is always inverted. Conversely, when 
set to Normal, the signal is not inverted.  
11 The RF1 22KHz is only applicable for dual band applications. Select whether to 
transmit the 22 kHz tone Local Oscillator control signal of RF1. The selections are 
On, Off, or Auto. Select Auto to use the crossover frequency to determine if the 
tone is transmitted. 
12 In the RF1 Power drop-down menu, set the power output of RF1 to the external 
Low Noise Block (LNB). 
You can set the RF1 Power to Off, 13V, 18V, V-NIT or H-NIT. When RF1 Power 
is set to V-NIT or H-NIT, it will use vertical and horizontal polarity until it is 
automatically read from the NIT. 
Note: Power will not be applied to the LNB when set to Off. 
13 In the RF Input LNB Configuration section, for RF1, RF2, RF3, and/or RF4, set 
the lower local oscillator frequency, in GHz, of the LNB in the LO1 (Ghz) 
column. If it is a single band oscillator, set its frequency, in GHz. You can enter a 
value in a range from 0.0 to 15.0 GHz. This value must be lower than the value 
for LO2. 
14 For RF1, RF2, RF3, and/or RF4, set the higher oscillator frequency, in GHz, of the 
LNB in the LO2 (Ghz) column. If it is a single band oscillator, set this value to 
0.0. You can enter a value in a range from 0.0 to 15.0 GHz. This value must be 
higher than the value for LO1. In single-band LNB applications, set this value to 
0.0. 
15 Enter the Crossover frequency for RF1, RF2, RF3, and/or RF4. This is an internal 
threshold frequency used for selecting the LO1 or LO2 frequency, depending on 
the current downlink frequency settings. This option is only used in dual-band 
LNB applications. 
You can enter a value in a range from 0.0 to 15.0 GHz. In a single-band LNB 
applications, set this value to 0.0. 
16 Select the signal Polarisation setting (Horizontal, Vertical, or Automatic). This 
setting is only applicable when the LNB Power is set to H-NIT or V-NIT. It marks 
the polarity of the signal connected to the current RF input.

17 Set the Orbital Position (Orbital Posn) for RF1, RF2, RF3, and/or RF4, in degrees. 
This is the location in orbit of the satellite currently being used. The satellite 
position (in degrees) in combination with the direction (either E (East) or W 
(West)) denotes the satellite position the dish connected to the current RF Input 
should point. This is used when the satellite is not available in the look-up menu 
list. 
For manual configuration, enter the location of the satellite using the numerical 
keypad. The receiver will not recognize the satellite name and identify it as 
Unknown. This setting is required to resolve any ambiguity between RF inputs 
during automatic disaster recovery. 
18 Select the East/West Flag for RF1, RF2, RF3, or RF4. This is the satellite position 
the dish connected to the current RF Input should point. The options are East, 
West, or N/A (Not Applicable). 
19 Click Apply. 
20 Click Validate Orbital Position to validate the RF inputs to match those 
expected by the network. The receiver will check to see if all frequencies in the 
Network Information Table (NIT) can be tuned to. The Date is displayed as the 
last date that the Validate operation was performed. 
21 Click Reacquire to re-acquire the signal using the tuning parameters from user 
settings. The Reacquire Network Information window is displayed. 
 
Select Reacquire Tuning & Channel List Only for the decoder to tune back to 
the user configured input and frequency and re-acquire the PSI/SI information 
back to the selected channel. Click OK. 
Note: This operation can take several minutes, depending on the size of the 
network. 
22 The Current Input Status section displays the current RF status.  
 
The following table describes the Current Input Status information displayed:

3 Set the Frequency Tuning Mode, which determines whether to use the NIT to 
tune to other transports, or to force the tuning to user configuration settings. 
Select NIT and the receiver can change tuning parameters to use all transports 
available in the NIT. Select User Cfg to force the receiver to use the user selected

the selected preset. The receiver’s network ID must match the network ID 
associated with the transmitted signal that identifies the NIT to be used. You can 
enter a value in the range from 1 to 65535. The default is 1.  
10 In the CA Mode drop-down list, select how the conditional access will attempt to 
descramble the scrambled programs. The behavior of this setting is different 
between PowerVu streams and those that require a CAM. 
For PowerVu Streams: 
- Std - In standard mode, if a program is not authorized, even if some services 
are not scrambled, the whole program will not be authorized. 
- Open - In open mode, if a program is not authorized, any services in the 
program that are not scrambled will still be available. 
For Non-PowerVu (CAM) streams: 
- Std - In standard mode, if a programs CA system is not supported by the 
CAM, the channel is not authorized. 
- Open - In open mode, all the programs CA systems are validated by the 
CAM. The channel is always authorized.

Setting up Muting Threshold Controls 
1 From the user interface of the D9854, click Input > Input Setup, expand Input 
Setup and then click Muting Thresholds. The Muting Thresholds page is 
displayed. 
 
2 Select Enable Threshold Muting to mute the transport stream and audio in the 
event of an unstable, poor, or loss of signal condition. The default is selected. 
3 The Transport Mute for both DVB-S C/N Margin (dB) and DVB-S2 C/N Margin 
(dB) sets the DVB-S and DVB-S2 Carrier to Noise margins, in dB, below the 
transport outputs that will be muted. The receiver uses these thresholds to 
determine when to mute the transport in the event of a noisy, poor, or loss of 
signal condition. The adjustable operating range is from -30.0 to 30.0 dB. This 
setting must be below the respective Restore value. The default setting is 0.0. 
Note: Enable Threshold Muting must be selected for these settings to be active. 
4 The Transport Restore for both DVB-S C/N Margin (dB) and DVB-S2 C/N 
Margin (dB) sets the DVB-S and DVB-S2 Carrier to Noise margins, in dB, above 
the transport outputs that will be muted. The receiver uses these thresholds to 
determine when to restore the transport after it has been muted. The adjustable 
operating range is from -30.0 to 30.0 dB. This setting must be above the 
respective Mute value. The default setting is 0.1. 
Note: Enable Threshold Muting must be selected for these settings to be active.

determine when to mute the audio in the event of a noisy, poor, or loss of signal 
condition. The adjustable operating range is -30.0 to 30.0 dB. This setting must be 
below the respective Restore value. The default setting is 0.0. 
Note: Enable Threshold Muting must be selected for these settings to be active. 
6 The Audio Restore for both DVB-S C/N Margin (dB) and DVB-S2 C/N Margin 
(dB) sets the DVB-S and DVB-S2 Carrier to Noise margins, in dB, above the
