3.1.8 Multiswitch Interference
(DSS Plus
™
IRD
Users Only)
TracVision 6 has the capability to switch from one satellite to
another when you choose TV channels that are carried by your
two selected satellites. However, some multiswitches (either
active or passive), such as the Channel Master model 6214IFD,
may interfere with the 22 KHz tone sent by DSS Plus IRDs to the
antenna. As a result, the antenna may not receive the signal to
change satellites when you change channels using your DSS Plus
remote.
In this case, you will need to use the maintenance port satellite
switch procedure explained in
Section 2.5.1, “Installing Your
Selected Satellites.”
3.1.9 Passive Multiswitch Used
(Latin and
North American Systems Only)
As noted in
Section 2.3.6.2, “Connecting the Antenna RF Signal
Cable to a Multiswitch (Latin and North American Systems Only),”
using a passive multiswitch may cause some signal loss and
possibly reduce the maximum reception range in fringe areas. An
active multiswitch can be used to connect more than two IRDs to
the TracVision 6 system. However, please refer to
Section 3.1.7,
”Multiswitch Interference,”
for an explanation of a potential issue
with the use of any type of multiswitch.

IRD Troubleshooting
The IRD that was provided with your satellite television service
may also be the cause of less-than-ideal operation. First check the
IRD’s configuration to ensure it is set up for the desired
programming. In the case of a faulty IRD, refer to your IRD user
manual for service and warranty information. If the IRD is both
configured properly and fully functional, contact your local KVH
dealer or service center for assistance.

Antenna Gyro and LNB Faults
Section 4, “Maintenance,”
provides detailed instructions for
authorized service personnel who may be required to replace the
TracVision 6 antenna gyro or the LNB.

TracVision 6 Installation and Technical Manual
Due to the signal polarization in
European satellites, the use of a
multiswitch (active or otherwise),
with a dual output LNB will result
in a loss of signal and less than
optimal operation with TracVision 6
systems used in Europe.
KVH Industries offers a quad-output
LNB for use with European systems
that will support more than two
television/IRD pairs. This quad-
output LNB will require a
multiswitch for proper use.
