Setting up the TS Input, Continued

9. Enter the Forward Error Correction (FEC) inner code rate. The FEC rate must

match the FEC of the transmitted signal. You can select 1/2, 2/3, 3/4, 5/6, 7/8

or Auto.

10. Set the input signal spectrum inversion setting (IQ), which allows the operator

to track and select inverted and non-inverted digital signals.

When set to Auto, received digital signals are tracked and inverted for correct

selection, as required. When set to Inv (inverted), the received digital signal is

always inverted. Conversely, when set to NonInv (non-inverted), the received

digital signal is never inverted.

11. 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.

12. For RF1, RF2, RF3, and/or RF4, enter the Local Oscillator frequency #1 (LO1),

which sets the satellite antenna LNB local oscillator #1 frequency. 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.

13. For RF1, RF2, RF3, and/or RF4, enter the Local Oscillator frequency #2 (LO2),

which sets the satellite antenna LNB local oscillator #2 frequency. 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. This value must be higher than the value for LO1. In single-

band LNB applications, set this value to 0.0.

14. Enter the Cross Over 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.

15. Set the Orbital Position 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.
