Section
Requirements
[SATELLITE]
The modem provides RX and TX frequency information via a data
connection to the SAILOR 900 VSAT High Power.
The single-cable solution makes it possible to configure the VSAT
modem to use any LO frequency in the range from 9.6 GHz to 11.3
GHz. The SAILOR 900 VSAT High Power will tune to the correct Ku-
Band frequency and provide the correct L-Band frequency to the VSAT
modem.
Example: “rx_lcl_osc = 11250.000000”
SAILOR 900 VSAT High Power has an extended Watt BUC with LO up
conversion frequency of 12.8 GHz.
— Example: “tx_lcl_osc = 12800.000000”
Note:
SAILOR 900 VSAT High Power supports any LNB frequency due
to the 1-cable design.
[MOBILE]
The iDirect modem must be set to mobile unit and receive the GPS
information from the ACU with the command “w <Valid> <Lat> <Lon>
<Time>”.
Example:
“is_mobile = 1”
Tx handshake must not be enabled in the iDirect modem.
Example:
“tx_handshake_enabled = 0”
[ODU]
The SAILOR 900 VSAT High Power can work either using the Rx or Tx
10 MHz reference signals provided by the modem or using its own
built-in 10 MHz reference signal. It is recommended to use the Tx 10
MHz reference signal from the modem. See also
Example:
“odu_rx_10_mhz = 1”
The SAILOR 900 VSAT High Power needs the Tx 10 MHz reference
signal in order to allow TX ON.
Example:
“odu_tx_10_mhz = 1”
