Cable Unwrap
The antenna unit can rotate a full 720° before coming to the end
of its cable. If it does so, the system automatically unwraps the
cable by quickly rotating the dish in the opposite direction.
During this process, your television transmission will be frozen
momentarily while the cable unwraps and the antenna reacquires
the satellite.
Sleep Mode (TracVision L3 only)
When the vehicle has come to a stop and the antenna holds its
position for 1 minute, the antenna unit enters Sleep Mode, which
turns off the conical scan tracking, reducing any motor noise the
antenna may be making. As soon as the vehicle moves, Sleep
Mode will automatically be turned off and the system will begin
tracking the satellite again. This convenient feature is ideal for
when a vehicle is parked for a short time or idling and
passengers want to watch TV.
KVH recognizes that some customers may not want to take
advantage of this convenient feature. In this case, it is possible to
disable Sleep Mode using a simple software command as follows:
1. Connect a laptop computer to the system using the
maintenance port and a terminal emulation
program, as described in
2. Turn on the antenna. When the limit switch test is
complete:
a. Type
HALT<cr>
(<cr> indicates a carriage
return/ENTER key).
b. Type
DEBUGON<cr>
.
c. Type
SLEEPOFF<cr>
.
3. Cycle the antenna’s power. Sleep Mode is now
disabled.
4. To reactivate Sleep Mode, follow this same
process, except type
SLEEPON<cr>
in Step c.

A Guide to TracVision L3/S3
Unlike turning the power off, the
antenna will still be operational and
drawing power when in Sleep
Mode. If you are going to be parked
for an extended period of time,
turning off the antenna will
conserve power while still allowing
you to receive the TV signals.
