SAILOR 900 VSAT High Power ADU interface
All communication between the ADU and the ACU passes through a single standard
50 Ohm cable (with N connector) through the rotary joint. No cable work is required inside
the radome.
Installation friendly
Four lifting brackets (included in the delivery) and reuse of packing material help getting the
ADU safely into place. Satellite profile parameters are entered using the built-in web server
of the ACU, using a PC.
Service friendly
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 DC Motor Driver modules 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 checks
constantly the ADU’s 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.
ADU software is updated automatically when making a software update of the ACU.
2.1.2
Antenna Control Unit (ACU)
The ACU is the central unit in the system. It contains all user interfaces and manages all
communication between the ADU and the connected VMU, 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 and VMU setups and enter
No Transmit Zones
(blocking zones in
which the ADU does not transmit).
The ACU provides DC power to the ADU through a single coaxial cable.
