TracVision S3 is designed to operate only while your vehicle is parked. Using Your TracVision L3/S3 When Parked When your vehicle is stopped, it is not necessary for the TracVision L3/S3 to be turned on. After parking your vehicle and confirming that the antenna is receiving the satellite signal, you may turn off the TracVision L3/S3 unit to avoid unnecessary use of power. Because the LNB receives its power from the IRD, the antenna will continue to receive the satellite TV signals and relay them to the IRD. However, if you plan to change to a channel that is broadcast by another satellite, TracVision L3/S3 must be turned on so the antenna can search for, identify, and lock onto the different satellite. (TracVision L3 only) Don’t forget to turn the system back on before you start driving again. The antenna must be turned on to track the satellite while you are moving. 54-0157 Rev. G A Guide to TracVision L3/S3 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. 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 Section 2.5.1, “Installing Your Selected Satellites.” 2. Turn on the antenna. When the limit switch test is complete: a. Type HALT ( indicates a carriage return/ENTER key). b. Type DEBUGON. c. Type SLEEPOFF. 3. Cycle the antenna’s power. Sleep Mode is now disabled. 4. To reactivate Sleep Mode, follow this same process, except type SLEEPON in Step c. Using Your TracVision L3/S3 Using Your TracVision L3/S3 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 L3/S3 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 road via satellite downloads and a wireless return path.
