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. Disconnect the two cables from the sensor
module (see Figure 3) as follows:
d1. Disconnect the GPS cable.
d2. Using a flat-head jeweler’s screwdriver,
loosen the Sensor cable connector’s DB9
retaining screws first to avoid breaking the
screws. Then fully disconnect the cable.

e. Using a #2 Phillips screwdriver, loosen the three
captive screws securing the sensor module to
the frame.
f. Remove the faulty sensor module.
Step 2 - Install the Replacement Sensor Module
Follow the steps below to secure the new sensor
module, reconnect the cables, close the hatch, and
apply power.
a. Secure the replacement sensor module to the
frame and tighten the captive screws to
21 in.-lbs.
b. Reconnect the two cables to the sensor module
at the locations shown in Figure 3.
When reconnecting the DB9 connector (the
Sensor Cable), tighten the retaining screws to
5 in.-lbs of torque. Do not overtighten – these
screws break easily.
c. Inspect the inside of the antenna to make sure
you have not left any tools or debris inside.

Step 4 - Calibrate the Gyros
Figure 5: Support Page and Command Line Icon
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.
Important!
Calibrate the gyros only while the vessel is
stationary in calm seas.
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 serial
number 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 5).
d. At the command line (see Figure 6), enter and
send the following commands:
•HALT
•DEBUGON
• EEUNLOCK
• =CALNEWGYRO
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
