A Guide to TracVision L2 Installing Two IRDs and TVs To connect a second TV and IRD to the TracVision L2 system, you must connect a second RF cable to the antenna’s RF2 connector (see Figure 2-12). Route the other end of the RF cable down into the vehicle and connect it directly to the second IRD. Connecting Three or More IRDs and TVs To install three or more IRD/TV pairs, an active multiswitch (Channel Master model 6214IFD or equivalent) must be placed between the antenna unit and the IRDs.
Installation 4. Terminate all unused output connectors with 75 ohm DC blocks (Channel Master #7184, Radio Shack #15-1259 or equivalent). 2.3.3 Sealing the Cable Access Hole Once the RF and data/power cables are connected to the antenna, you need to seal and cover the cable access hole to protect against leakage. 1. Completely seal the cable access hole with silicone sealant or RTV. 2.
A Guide to TracVision L2 2.3.5 Connecting the Switchplate to Vehicle Power Before connecting the antenna unit to vehicle power, remove the appropriate vehicle fuse to prevent a short circuit. Replace the fuse after the connection to vehicle power is complete. The switchplate must be connected to a +12 Vdc, 2.5-3.5 amp power supply to operate. 1. Disconnect vehicle power by removing the appropriate vehicle fuse. 2. Run a cable from vehicle’s power (11-16 Vdc) out through the panel cutout. 3.
Installation 2.4 Activating the IRD KVH makes it easy to activate your IRD. Just call KVH at 1-888-584-4163 and ask for IRD Activation (Monday - Friday, 8:30 a.m. - 5:00 p.m. EST). For other options, please refer to the user manual that accompanied your IRD. Note that EchoStar IRDs that have not been activated within several months of manufacture require additional steps to complete the process. Refer to Appendix D for complete details. 2.
A Guide to TracVision L2 Table 2-3 TracVision L2 Operational Messages The DISH Network and some newer IRDs (e.g., the Sony A50) give priority to internal IRD messages rather than on-screen messages. KVH recommends that the maintenance port be used to read installation-related messages on a PC (see Section 2.5.2, “Checking Out the System Without an IRD Data Connection”).
Installation 2.5.2 Checking Out the System Without an IRD Data Connection To ensure that the system is configured and operating properly, you will need to check the data provided in the system’s startup routine. To do so, you need to connect a PC to the antenna baseplate’s maintenance port. The diagnostics procedure requires terminal emulation software such as PROCOMM or Windows Terminal or Hyperterminal. Use the settings appropriate to your application. 1.
A Guide to TracVision L2 4. Press the switchplate’s POWER button to apply power to the TracVision L2 system and wait for the system to fully initialize. Data should be scrolling on the PC display to identify any system problems detected. If no data is seen, recheck your connections and the terminal software setup. 5. After completing the review of the startup and operational routines, shut down the system. 2.
Using Your TracVision L2 3 Using Your TracVision L2 For TracVision L2 to receive the satellite signals, the antenna must have a clear line of sight to the satellite. If you only receive intermittent signals or the antenna cannot find the satellite, check around your vehicle for any objects that could be blocking the signal, such as trees, buildings, highway overpasses, etc.
A Guide to TracVision L2 Figure 3-2 Switchplate Front Panel Status Indicator Power Button Sat Select Button These features only active if the system is NOT connected to an IRD low-speed data port 3. Avoid turning for 60 seconds after turning on the antenna to allow the antenna gyro to inialize properly. If Connected to an IRD Low-speed Data Port: As part of the startup process, the TracVision L2 system will default to Channel 200, a program directory.
Using Your TracVision L2 3.2 Tracking the Correct Satellite If your system is connected to an IRD’s low-speed data port, follow the steps in Section 3.2.1, “Using the IRD for Satellite Selection.” If your system is not connected to an IRD’s low-speed data port, follow the steps in Section 3.2.2, “Using the Switchplate for Satellite Selection.” 3.2.
A Guide to TracVision L2 3.3 Turning Off the System To turn off the TracVision L2 system, simply press the switchplate’s POWER button (see Figure 3-2). 3.4 Watching Television TracVision L2 is designed to operate as efficiently and as reliably as possible whether your vehicle is in motion or parked. Using Your TracVision L2 When Parked 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.
Using Your TracVision L2 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.
