2..1.2.2
SAILOR 900 VSAT 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.
2..1.2.3
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.
2..1.2.4
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 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 checks constantly the ADU’s components 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.
2.1.3
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 connected the
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.
You can use the SAILOR 6080 Power Supply to provide the DC power
for the ACU.
