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.
Introduction
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.
The included cable relief support can be attached to the ACU.
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 (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.
