TracVision 6 Technical
Manual Addendum
(ECO #s 5959, 5503, 5315, 6138, 6198)
The following changes have been made to Revision B of the
TracVision 6 Installation and Technical Manual (KVH Part
Number 54-0166).
3.1.1 Blown Fuse, Low Power, or Wiring
The 4-amp fuse on the CPU Printed Circuit Board (PCB) has been
replaced with two 3.15-amp fuses to better protect the Antenna Unit’s
electronics.
1. Blown Fuse – The Antenna Unit is equipped with
two fuses mounted on its CPU Board. If either of
these fuses has blown or been broken, the
Antenna Unit will not operate. Refer to Section 4.4,
“PCB Removal and Replacement,” for details on the
fuse locations and how to access the CPU Board.
4.3 TracVision 6 Field
Replaceable Units
Table 4-1 has been updated to show the new part number for the
3.15-amp fuses and the new part numbers for the RF Detector PCB and
European LNB. The azimuth limit switch has also been added to the
list.

4.4 PCB Removal and Replacement
The printed circuit boards (PCBs) are protected by a cover
fastened to the antenna support frame. The cover must be
removed to gain access to the main power fuses and the
PCB assemblies discussed below. Refer to Figure 4-2; remove
3 nuts and washers from the bottom flange and 3 screws and
washers from the upper flange. Remove the cover and set aside
with the fasteners.
The CPU PCB has been changed from an “L”-shaped design to a
simpler straight design. Figure 4-3 has been updated to show the new
CPU PCB.

4.4.1 CPU Board
The new CPU Board is secured to the antenna frame using nine screws
rather than eleven.
2. Remove nine #6-32 machine screws from the PCB.
The following procedure has been inserted for replacing the azimuth
limit switch. As a result, Sections 4.6 through 4.8 of the Installation
and Technical Manual have been renumbered Sections 4.7 through 4.9.
4.6 Azimuth Limit Switch Assembly
Replacement
1. Rotate the antenna assembly, by hand, clockwise
until it stops.
2. Remove the printed circuit board (PCB) cover,
illustrated in Figure 4-2, using a #2 Phillips
screwdriver and a 3⁄8" nut driver/socket.
3. At the CPU’s Molex connector, cut the black and
white wires from the azimuth limit switch (see
Figure 4-3). Leave about one inch (25 mm) of the
wires still connected for later reference.
4. At the azimuth limit switch cover, remove the hot
melt keeping the black and white wires in place
(see Figure 4-7).

5. Remove the three #6-32 x 3⁄8" retaining screws from
the limit switch cover and set aside (see
Figure 4-7). Lift the cover to access the limit switch
underneath.
6. Remove the four #8-32 x 1⁄2" screws securing the
limit switch to the cover and set aside.
7. Replace the azimuth limit switch. Attach the new
switch to the cover using the #8 screws, flat
washers, and cable clamp.
8. Route the new limit switch wires through the
cover and cable clamp to the CPU’s Molex
connector. After noting the position of the old
black and white wires, remove the old wires from
the Molex connector. Attach the new wires in their
place.
9. Before re-installing the azimuth limit switch to the
antenna assembly, orient the switch’s plastic cam
as shown in Figure 4-8. With the cam in the proper
position, reinstall the switch to the antenna
assembly using the three #6 retaining screws and
flat washers. Ensure the cam finger engages the
stop pin in the mounting cavity.
10. Apply hot melt or RTV at the limit switch cover’s
wire access hole to protect the wires from chafing.
