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 setup 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. 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. You can make a software update with a connected PC and the built-in web
interface of the ACU.
