The following instructions explain how to replace
the main board in a TracVision®HD11 antenna.
NOTE: Your antenna might have parts that differ from
those pictured in this document. Such differences have no
bearing on the instructions unless noted otherwise.
Tools Required
This procedure requires the following tools:
• Headband light
•ESDwriststrap
• 7/16" torque wrench set to 15 in.-lbs
• Phillips screwdrivers
• Torque wrench with Phillips bits (11 in.-lbs and
21 in.-lbs)
• Flat-head jeweler’s torque screwdriver set to
5 in.-lbs
• Latest HD11 software update file downloaded
to a laptop computer via the KVH Partner Portal
or to a mobile device via the KVH HD11 app
Step 1 - Remove the Old Main Board
Follow the steps below to remove the old main
board.
a. Turn off the ACU to remove power from the
antenna.
CAUTION
For your own safety, disconnect power from all
wired components before you begin.

b. Disconnect the power/data cable from the back
of the ACU and unplug the AC power cable
from its power source.
NOTE: Follow all shipboard lockout-tagout procedures,
where applicable.
c. Using a 7/16" socket/ratchet or nut driver,
unlock the three hex latches securing one of the
service hatches to the baseplate (see Figure 2).
Open the hatch.
NOTE: If you are unable to work through the hatch, you
may remove the radome instead. If possible, open the
second hatch as well to allow in more light. Use a
headband light if needed.
d. Put on an ESD wrist strap and connect it to any
bare metal portion of the antenna frame.
e. Disconnect all nine cables from the main board
(see Figure 3).
Using a flat-head jeweler’s screwdriver, loosen
the DB9 connectors’ retaining screws (nos. 1-2
and 4-8 in Figure 3) first to avoid breaking the
screws. Then fully disconnect the cable.
To avoid stressing the RF cable (no. 3 in
Figure 3), hold the base of the connector while
loosening with a 7/16" open-end wrench.
f. Loosen the four captive screws securing the
main board to the frame (see Figure 4).
g. Remove the faulty main board.
Important!
The main board is static-sensitive. Be sure to take
the proper grounding precautions before handling.
Important!
Do not use excessive force when loosening or
tightening the DB9 connectors’ retaining screws.

Step 2 - Install the Replacement Main Board
Follow the steps below to secure the new main
board, reconnect the cables, close the hatch, and
apply power.
a. Secure the replacement main board to the frame
and tighten the screws to 21 in.-lbs of torque
(see Figure 5).
b. Reconnect the nine cables to the main board.
Reconnect cable no. 9 (power cable) last (see
Figure 6).
When reconnecting the DB9 connectors (nos. 1-2
and 4-8 in Figure 6), tighten the retaining screws
to 5 in.-lbs of torque. Do not overtighten – these
screws break easily.
When reconnecting the coax cable (no. 3 in
Figure 6), hold the connector body while
tightening the connector nut. Tighten to
15 in.-lbs of torque.
c. Slowly rotate the antenna assembly by hand a
full 360º in both directions, and move the
antenna through its full range of elevation and
cross-azimuth. Make sure the cables do not get
caught on anything or restrict movement.
d. Inspect the inside of the antenna to make sure
you have not left any tools or debris inside.
e. Close all open hatches and lock their three hex
latches (see Figure 7).
f. Reconnect the power/data and AC power
cables to the ACU and turn on the antenna.
Then wait five minutes for system startup.
Step 3 - Update the Software
Follow the instructions in the TracVision HD11
Installation Guide or User’s Guide to update the
system software to the latest version.

Step 4 - Calibrate the Gyros
The sensor module’s gyros need to be calibrated to
work with the antenna’s main board. Follow the
steps below to calibrate the gyros.
a. Connect your computer to the HD11’s Ethernet
or Wi-Fi network. Then type the ACU’s serial
number into your web browser’s address bar, as
shown below:
http://hd11-<ACU serial number>.local
NOTE: You can view the ACU’s IP address and the
ACU and antenna serial numbers on the ACU’s front
panel display. Press MENUS until the display shows
“ABOUT SYSTEM”, press ACCEPT, and then scroll
through until you see the desired information.
b. Log into the web interface:
Default Username: admin
Default Password: password
c. At the Support page of the web interface, select
Command Line (Figure 8).
d. At the command line (see Figure 9), enter and
send the following commands:
•HALT
•DEBUGON
• EEUNLOCK
• =SERNUM,<9-digit antenna serial
number>
• =SERNUM
NOTE: The serial number you entered should appear in
the Live Comms window.
• =CALNEWGYRO
Important!
Calibrate the gyros only while the vessel is
stationary in calm seas.

e. After calibration is complete, verify that the
azimuth (AZ), elevation (EL), and skew gyros
all pass, then enter and send the following
command:
•ZAP
Step 5 - Test the System
Test the system for normal operation. If the problem
persists, contact KVH Technical Support.
The replacement procedure is complete!
