Step 1 - Replace the Main Board
Follow the steps below to replace the main board.
a. Power off and unplug the TV-Hub to disconnect
power from the antenna.
CAUTION
Make sure the antenna is pointed away from the
sun whenever the radome is removed. The highgloss reflector can focus sunlight into a narrow
beam, generating a significant amount of heat
that can cause damage and injury.

b. Remove and discard the four #8-32 screws

Figure 3: Main Board Screws and Cable Connectors
Figure 4: Main Board Cover M4 Screws
securing the radome to the baseplate (see
Figure 2). Carefully lift the radome straight up
until clear of the antenna assembly and set it
aside in a safe place. Do not place the radome on
a hot steel surface– the heat may warp the
radome.
Important!
The main board is static-sensitive. Be sure to take
the proper grounding precautions before handling.
c. Put on an ESD wrist strap and connect it to the
nearest ground.
d. Disconnect the gyro cable and the two RF cables
from the main board (see Figure 3, connectors
1-3). To avoid stressing the RF cables, hold the
body of the connector while loosening the
connector nut.
e. Using a #2 Phillips screwdriver, remove and
discard the two M4 screws that hold the main
board cover in place (see locations 1 and 2 in
Figure 4). Then carefully lift and slide the cover
out of the front of the antenna frame to gain
access to the main board.

f. Carefully disconnect the remaining cables from
the main board, taking note of the exact location
and orientation of each (see Figure 3).
g. Remove and discard the five M3 screws that
secure the main board to the mounting posts
(see Figure 3).
h. Remove the main board.

i. Remove any of the six thermal pads that may
Figure 5: Heat Sink Blocks and Serial Number Location
Figure 6: Thermal Pad Stencils (Back of the Main Board)
Figure 7: Main Board Mounting Holes and Cable Connectors
still be attached to heat sink blocks on the
antenna frame (see Figure 5). Then clean the
heat sink blocks with alcohol and dry.
j. Remove six new thermal pads from the blue
plastic backing (supplied in kit) and gently press
them onto the back of the new main board
within the stenciled outlines (see Figure 6).
k. Note the antenna serial number, located on the
frame, as shown in Figure 5. You will need to
enter this 9-digit number later.
Important!
Do not lower the replacement main board into
place until it is aligned perfectly above the
mounting posts. Doing so might disturb and
damage the thermal pads, resulting in potential
failure of the board.
l. Position the new main board over the mounting
holes at the five locations shown in Figure 7.
Lower the main board down onto the mounting
holes and hold it in place firmly, while securing
it with five new M3 screws (supplied in kit) in an
alternating cross-corner pattern. Tighten the
screws to 11 in.-lbs of torque.
m. Reconnect the cables to the main board (see
Figure 7, connectors 4 and 5).
Important!
Make sure that no wires get pinched between the
main board cover and the frame, and that the cover
is benched against the back of the frame before it is
secured.
n. Carefully reinstall the main board cover and
secure it in place with two new M4 screws
(supplied in kit). Then tighten the screws to
11 in.-lbs of torque.
o. Reconnect the gyro cable and the two RF cables
to the main board (see Figure 7, connectors 1-3).
Hold the connector body while tightening the
connector nut. Tighten to 15 in.-lbs of torque.
p. Slowly rotate the antenna assembly through its
elevation range to ensure the main board cover
does not restrict the antenna’s movement.

q. Inspect the inside of the antenna to make sure
you have not left any debris or tools inside.

r. Inspect the four clip-on nuts installed in the
Figure 8: Clip-On Nut Location (x4)
Figure 9: Technician Mode
Figure 10: LNB Type Drop-Down Menu
baseplate (see Figure 8). If any are damaged or
missing, replace with one of the four new
clip-on nuts (supplied in kit).
s. Reinstall the radome onto the antenna, aligning
the radome labels forward and aft.
t. Secure the radome with four new #8-32 screws
(7/16" long) (supplied in the kit). Then tighten the
screws to 5 in.-lbs of torque.
u. Hide and protect the radome screws with the
plastic screw caps (supplied in kit).
v. Reconnect power to the TV-Hub.
Step 2 - Update the Software
Connect your computer to the TV-Hub and access
its web interface, then follow the instructions in the
TracVision TV1/RV1 Help to update the system
software to the latest version.
Step 3 - Register the LNB
If a standard circular LNB is installed in the
antenna, skip to step 4.
Otherwise, follow the steps below to register the
LNB with the new main board.
a. If your computer is disconnected from the
TV-Hub, reconnect now to access its web
interface. (Refer to the TracVision system’s
Quick Start Guide for details.)
b. At the Settings page of the web interface, choose
Advanced Settings and set Technician Mode to
On (see
c. From the LNB Type drop-down menu, choose
your currently installed LNB (see
Then click Select.
d. The TV-Hub will confirm that you want to
change the LNB type. Click OK to confirm the
change.
Figure 9).
Figure 10).

Step 4 - Enter the Antenna Serial Number
Figure 11: Command Line
and Calibrate the Gyros
Follow the steps below to enter the antenna serial
number through the web interface and calibrate the
gyros. Since the main board stores the bias values
for the antenna’s gyros, you need to calibrate the
gyros whenever you replace the main board.
Important!
Calibrate the gyros only while the vessel is
stationary in calm seas or the vehicle is parked.
a. If your computer is disconnected from the
TV-Hub, reconnect now to access its web
interface. (Refer to the TracVision system’s Quick
Start Guide for details.)
b. At the Support page of the web interface, select
Command Line.
c. At the command line, enter and send the
following commands:
• HALT
• DEBUGON
• EEUNLOCK
• =SERNUM,<9-digit antenna serial number> (example: =SERNUM,140802543)
• =CALACCELOFFSET
d. After gyro calibration is complete, and the TV-
Hub returns a “PASS” message, enter and send
the following command:
• =CALNEWGYRO
NOTE: Gyro calibration can take up to fifteen
minutes. The command line will display
“INITIALIZING” during the process.
e. After gyro calibration is complete and the
TV-Hub returns a “PASS” message from both
gyros, enter and send the following command:
• ZAP
f. Reconnect to the TV-Hub web interface and run
the Setup Wizard to select satellites and
services.
