Requirements
[SATELLITE] The modem provides RX and TX frequency
information via a data connection to the SAILOR
900 VSAT.
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 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 has an extended 8 Watt BUC
with LO up conversion frequency of 12.8 GHz.
— Example: “tx_lcl_osc = 12800.000000”
Note:
SAILOR 900 VSAT 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 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
VSAT
modem profile – New entry and Edit on page 6-23.
Example:
“odu_rx_10_mhz = 1”
The SAILOR 900 VSAT needs the Tx 10 MHz
reference signal in order to allow TX ON.
Example:
“odu_tx_10_mhz = 1”
