Installation 54-0198 21 2.1 Planning the Installation Who Should Install the T racVision G8? KVH recommends that a KVH-authorized technician install the T racV ision G8 system. Installers should have experience installing electronic equipment on a vessel.
• Power cable to connect the MCU to ship’s power (T able 2-2 provides pr oper gauge and length specifications for a 12V supply . The system will not work if the MCU receives less than 9V). T able 2-2 Recommended Power Cable Specifications Cable Length Cable Gauge to 40 ft (12 m) 12 A WG (1.
T able 2-3 Kitpack Contents (continued) Pa r t Pa r t # Q t y . #6 flat washers 14-0024 2 Small F err ite Coil 29-0088 1 Large F err ite Coil 29-0090 1 F-type connector 23-0213 1 Choosing Component Locations When choosing component locations, first keep in mind accessibility and cable lengths between units.
• T o minimize tracking errors, place the antenna unit as close as possible to the intersection of the vessel’s fore- and-aft centerline and midships. In addition, do not mount the antenna too high off the water (limit height above the waterline to less than half the vessel length) .
Figure 2-2 Antenna Unit Dimensions Choosing the Best Location for the MCU • The MCU should be mounted in a dry location, allowing enough room at the back for connecting system cables. Also be sure to mount the MCU in a well-ventilated ar ea to prevent over heating, which will damage the system.
2.2 Mounting the T racVision Antenna T o mount the antenna to the vessel, follow the steps below . 1. Make sure that you have chosen a suitable mounting location based upon the guidelines in “ Choosing the Best Location for the T racV ision Antenna” on page 23 .
6. Remove the eight screws securing the radome to the baseplate. Carefully lift the radome straight up until clear of the antenna assembly and set it aside in a safe place. If you bring the radome topside, secure it with a lanyard to prevent it fr om falling overboard.
Figure 2-6 Baseplate Connectors 10. Connect the N-type connector end of the data/power cable to the baseplate, as shown in Figures 2-7 and 2-8. Figure 2-7 Data/power Cable Connectors Figure 2-8 Connec.
1 1. Using a 9 ⁄ 16 " wrench, connect the RF cable(s) from belowdecks to the baseplate. If you connect more than one RF cable, label both ends of each RF cable to match its antenna baseplate connector (RF1, RF2, RF3, or RF4). Figure 2-9 shows an RF cable connected to the RF1 connector .
14. Place the antenna baseplate over the mounting holes drilled in the foundation, ensuring the connectors face the stern. 15. At each of the four baseplate mounting holes, place an M10 lock washer and flat washer on an M10 bolt and insert the bolt into the hole from below , as shown in Figure 2-1 1.
17. Reinstall the radome. Secur e in place with the eight screws you r emoved in Step 6. Install a protective plastic screw cap fr om the kitpack over each screw . 2.3 Connecting the Receiver(s) Connecting the RF Cable(s) Each RF cable must be an RG-1 1 (75 ohms) or RG-6 (75 ohms) cable fitted with F-type connectors.
Option 3 - Connecting Three or More Receivers (System Equipped with Circular Dual LNB) T o connect three or four r eceivers to the T racV ision antenna, you will need to install an active multiswitch (Channel Master model 6214IFD or equivalent) between the antenna and the receivers.
Multiple Multiswitch Installation If you need to connect more than four r eceivers to the T racV ision antenna, you may carry out a multiple multiswitch installation, as shown in Figure 2-14.
Option 3 - Connecting Three or More Receivers (System Equipped with a Linear Quad LNB) Systems equipped with a linear quad LNB have four RF outputs that can be connected to individual receivers.
2.4 Wiring the MCU All other wiring for the T racV ision system connects at the rear panel of the MCU. For the T racV ision system to work properly , you must connect the following cables to the MCU: • Antenna data/power cable • V essel power cable Figure 2-16 shows the MCU’s r ear panel connectors.
Connecting Vessel Power and the MCU Ground Wire Short circuits may r esult in severe electrical shock or burns. T urn off vessel power and test the cir cuit to ensure that no power is present befor e connecting any power cables. Do NOT reapply power until all system wiring is completed.
2. Find the power plug provided in the kitpack and insert your vessel power wires into the plug’s (+) and (-) terminals (see Figure 2-18). Figure 2-18 Power Plug 3. Secure the wir es in place by tightening the plug’s terminal screws. 4. After inserting and securing the wires, tug gently to ensure that the connections ar e solid.
2.5 Mounting the MCU Mount the MCU using either of the following options: Option 1 - V elcro Fastening on a Horizontal Surface Option 2 - Flush-mounting The following sections describe how to mount the MCU for both of these options. Option 1 - Velcro Fastening on a Horizontal Surface 1.
Option 2 - Flush-mounting 1. Choose a location based upon the guidelines in “ Choosing the Best Location for the MCU” on page 25. 2. A template has been provided in Appendix B on page 125 as a guide to mark and cut the proper hole for the flush mount bracket.

3.2 Main Display and Accessing the Main Menu As soon as the startup routine is completed, the LCD panel shows the main display , which shows which satellite the antenna is currently tracking. The buttons allow you to switch between the two installed satellites as well as enter the main menu.
The RETURN and CANCEL Buttons Throughout the menus, the right-hand button will often be designated as either RETURN or CANCEL. These options have the following functions: • RETURN – Returns to the main menu or display . If no buttons are pr essed within 10 seconds, the menu will automatically default to the main display .
3.3 Installing Satellites T racV ision G8 permits two satellite services (Satellites A and B) to be installed simultaneously . There is also an option for NONE on Satellite B, permitting single satellite operation.
Available Satellite Pairs North America Any two of the North American satellites listed below can be paired together , as long as the satellites are within range of the antenna (standard cir cular dua.
3.4 Restarting the Antenna T o restart the antenna, use the Restart Antenna menu. The antenna will re-initialize and r eacquire the satellite. Figure 3-6 Restart Antenna Menu 3.
