13 The transmitter is unable to range because it
cannot communicate with the gateway Ranging is the automated process of adjusting
satellite transmitter timing and power. The satellite
transmitter performs ranging as necessary to ensure
that it can communicate successfully with the HX
system gateway. This condition can indicate any of
the following:
• The system gateway is not receiving ranging
information from the transmitter. This may indicate
a problem at the gateway and should resolve itself
within a few minutes.
• The transmitter is unable to achieve enough power
to send ranging information to the system
gateway.
• The transmitter is sending incorrect timing data
because incorrect latitude/longitude information
was entered during installation.
• The outdoor transmitter unit (ODU) is not
operating properly or is not properly connected to
the satellite router. Ensure that the transmit cable
is securely fastened to the TRANSMIT connector.
(See the Caution statement that follows Figure 2 on
page 13.)
14 The transmitter is not available because
ranging has failed Indicates that the transmitter is not operational due
to a ranging failure. Ranging is the automated
process of adjusting satellite transmitter timing and
power. The satellite transmitter performs ranging as
necessary to ensure that it can communicate
successfully with the system gateway. A ranging
failure may occur due to antenna misalignment or
after several failed ranging attempts. Realign the
antenna as necessary. This condition may also be
caused by adverse weather conditions. In rare
cases, this condition may also indicate system
gateway issues but, in such cases, should clear
within a few minutes. For repeated messages of this
type on a system that was previously operational, try
to force ranging by performing the Connectivity Test.
15 The transmitter is waiting for a ranging request
to be processed by the gateway Occurs when the system is busy adjusting power
and timing for other users. This process may take up
to a minute or more.
16 The transmitter is waiting for a transmit request
to be processed by the gateway Occurs when the system is unable to provide
transmit bandwidth due to a large number of users
signing on simultaneously. This condition should
clear itself within a few minutes.
