KVH Industries TracVision 4 Satellite TV System User Manual


 
3. Fine-tuning/Satellite – When a signal is detected,
the antenna interrupts the search mode and begins
a procedure to fine-tune the position for maximum
signal strength. When the signal peak is found, the
RF circuitry verifies the ID of the acquired satellite.
If the ID is correct, the system enters tracking
mode; if it is wrong, it resumes the search. Once
the satellite has been acquired, the system updates
the satellite location stored in memory.
3.1 Watching Your Selected
Satellites
TracVision 4 can have a pair of satellites installed, either one
of which can be the active satellite selection. There are several
methods to select whether your TracVision 4 will track
Satellite A or B based upon your location and selected satellite
service.
Maintenance Port Switch
As described in Section 2.4, “Selecting the Active Satellite,” the
maintenance port is used to tell the Antenna Unit which satellite
it should acquire and track. To make the antenna track either
Satellite A or B, first connect the PC to the maintenance port as
described in Section 2.4. Once the data connection is made, enter
the Satellite Selection parser command as follows:
Command: @L,x<cr>
Where: x = A or B (one of your selected satellites as
defined during the SATINSTALL process)
Choosing A or B will assign the antenna to acquire and track that
installed satellite.
DIRECTV Satellite Subscribers
DIRECTV subscribers in certain regions of the United States will
require a DSS Plus
IRD to receive both satellite and local
channels. Check with DIRECTV for regional requirements. The
DSS Plus IRD allows you to switch channels using the remote
control. If you are a DIRECTV subscriber, but do not have a DSS
Plus IRD, use the maintenance port switching option previously
described.
