A.1.1 VSAT LNB user installation and configuration information
The FV-110 can interpret 4-band LNB switching signals as well as exact LO information acquired
directly from the attached VSAT modem by means of a data connection.
When using a VSAT modem which is integrated to use LO information transferred via a data
connection, the LO must be in the range of 9.6 GHz to 11.3 GHz (Optimum values are 9.75 GHz and
10.75 GHz as these match the physical LNB values).
All VSAT modems that can be used with FV-110 use this approach for selecting the LO frequency,
except a COMTECH modem with ROSS server. A COMTECH modem with ROSS server reads
switching signals by means of a data connection instead of using voltage and tone signals.
Example configuration for an iDirect i5100 (L-Band range 950 - 1700 MHz)
Ku-Band frequency: 11.7389 GHz
L-Band frequency: 1638.9 MHz
LO: 10.1 GHz
Since the LO frequency of 10.1 GHz is in the range of 9.6 GHz to 11.3 GHz, this is a valid set of data.
The FV-110 will tune to 11.7389 GHz and provide the carrier on the L-Band frequency 1638.9 MHz.
Example configuration for a special VSAT modem (L-Band range 950 - 1450 MHz)
Ku-Band frequency: 12.750 GHz
L-Band frequency: 1450 MHz
LO: 11.3 GHz
Since the LO frequency of 11.3 GHz is in the range of 9.6 GHz to 11.3 GHz, this is a valid set of data.
The FV-110 will tune to 12.750 GHz and provide the carrier on the L-Band frequency 1450 MHz.
