3.2 Changing Channels and
Switching to the Second
Satellite
TracVision L3 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 L3 will track
Satellite A or B.
IRD Remote Control
If you have followed the installation instructions, your system
should be set to the active satellite pair of your choice and the
system should have downloaded the appropriate channel guides.
You must also have a properly configured IRD (if this has not
been done, refer to your IRD User’s Manual for instructions for
your specific IRD). When the TracVision L3 system and the IRD
have matching configurations, switching from one satellite to the
other is as easy as changing the channel using the remote control.
TracVision L3 will automatically switch from Satellite A to B and
back again as necessary to receive your selected channel.
Maintenance Port Switch
As described in Section 2.4, “Selecting the Active Satellite,” the
maintenance port can also be 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

A Guide to TracVision L3
The satellite configuration on
your IRD must match the satellite
setting on the TracVision L3
system.
Satellite A on the TracVision L3
must be the same satellite as IRD
Alternative 1 (or A, based on your
IRD) and must be assigned the IRD
DiSEqC 1 setting.
Satellite B on the TracVision L3
must be the same satellite as IRD
Alternative 2 (or B, based on your
IRD) and must be assigned the IRD
DiSEqC 2 setting.
Refer to your IRD user manual for
complete instructions for your IRD.
* DiSEqC applies to European systems only
