Chapter 2: Introduction
98-146706-A
Four lifting brackets (included in the delivery) and reuse of packing material help getting the
ADU safely into place. Satellite profile parameters are entered in the built-in web server of
the ACU, using a PC.
The system configuration is saved in two modules, there is no loss of data at repair. The
large service hatch of the radome gives easy access to the ADU on site. The service switch
in the ADU stops the Motor Driver modules and turns the BUC off. The service tools for
replacing modules are placed on a tool holder inside the radome.
All modules have a service and power LED status indicator. Each module is encapsulated in a
metal box with self-contained mounting bolts. If necessary, belts and modules can be
exchanged through the service hatch on site.
You can do remote diagnostics and service with the ADU. Its built-in test equipment
constantly checks the modules for proper functioning, it monitors and logs information for
all modules. The ADU performs a POST (Power On Self Test) and you can request a self test
(PAST, Person Activated Self Test) and Continuous Monitoring (CM). Error codes can be
read out in the web interface and in the display of the ACU.
The ADU software is updated automatically when you make a software update of the ACU.
2.1.3
Antenna Control Unit (ACU)
The ACU is the central control unit in the system. It contains all user interfaces and
manages all communication between the ADU and the connected modem, a connected PC
and an optional FleetBroadband service communication line. The ACU has a display, status
LEDs and a keypad. It provides a DHCP client. During configuration you can configure
heading offset, save satellite setups and enter
No Transmit Zones
(blocking zones in which
the ADU does not transmit).
The user PC (user WAN) for Internet access etc. is connected to the ACU, not the modem.
The ACU provides DC power to the ADU through a single coaxial cable. You can use the
SAILOR 6080 AC/DC Power Supply to provide the DC power to the ACU. The ACU comes in
a 19” rack version.
You can do remote diagnostics and service with the ACU. Its built-in test equipment
constantly checks the device for proper functioning. It performs POST (Power On Self Test)
and you can request a PAST (Person Activated Self Test). Continuous Monitoring (CM) is
also available. BITE error codes can be read out in the web interface and in the display of
the ACU.
