ONNECTION TO THE

NTERNET

After power is applied, the Hughes 9450 IDU and Hughes Tracking Antenna will begin their start-

up sequence. The tracking antenna will begin its search for the BGAN satellite and the antenna

motors may be heard during this time. Note that the tracking antenna must have line of sight to

the BGAN satellite. Once the antenna has locked onto the BGAN satellite, it will continue to

make minor adjustments to acquire optimum signal strength. The antenna may be heard

‘twitching’ during this time. Eventually the antenna will sit at an optimum position while the

vehicle is stationary.

Once the vehicle starts moving, the Hughes Tracking Antenna will automatically track the

satellite signal and keep the antenna pointed towards the satellite. During short outages (e.g.

while driving under a bridge, etc.) the antenna will remain in the same position and will pick up

the satellite signal immediately. For longer outages the antenna may need to repeat the search

pattern to reacquire the satellite signal.

Note

Circuit switched and packet switched connections will typically recover from signal

outages of less than 60 seconds. User intervention will be required to reactivate

circuit switched connections for outages longer than 60 seconds and may be

required for packet switched connections depending upon the actual length of

outage. Packet switched connections like FTP are more robust than circuit

switched connections in the network.

ONNECTING THE

ERMINAL TO THE

OMPUTER

You can connect your computer to the 9450 IDU with one or more of the following interfaces

 Ethernet

 Integrated Services Digital Network (ISDN)



Note

There is no need to check the active interface. All interfaces can be used

simultaneously to accommodate multiple users.



Note

During initial setup, the terminal can only be configured using either a USB or an

Ethernet connection. Once the terminal has been configured, four of the five

interfaces (Ethernet, WLAN and ISDN) can be used for data transfer depending

on the service required.

Your computer must be configured to support your chosen connection method.

Refer to the documentation supplied with your computer for details.
