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 Section 2.5.1, “Installing
Your Selected Satellites.”
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.

Conical Scan Tracking

The antenna control unit uses conical scanning to maintain peak
signal strength to the receiver and to update the satellite’s
position. When conical scan tracking is active, the antenna moves
continually with a circular motion to sweep across the satellite’s
peak signal. The signal strength is then fed back to the control
circuits to keep coming back to the direction of the strongest
signal.
If the satellite signal is lost while the system is in conical scan
track mode, the control software imposes a 45-second time-out
delay. If the signal is not regained during that time, the antenna
reverts to the set of Search Modes to start looking for the satellite
signal. This is an automatic process that does not require user
intervention.
3.4 Internet Access
Your TracVision C3 can receive high-speed Internet data when
used in conjunction with KVH’s TracNet 2.0 Mobile High-speed
Internet System. With TracNet 2.0, you get broadband Internet
access on the move via satellite downloads and a wireless return
path. For more information about TracNet 2.0 in North America
