3.1.7.2 Connect to a ANET1553 using the AIM API-Library
To connect to an ANET1553 via customer specific applications using the AIM
Application Programming Interface Library (API-Library), the following steps are
necessary.
a) To establishe a network connection to a ANET1553, with the AIM Network
Server (ANS) running , the API
function “ApiConnectToServer” has to be called.
As already mentioned above, the alias name or IP Address must be passed as a
parameter for proper initialisation of the API network connection.
b) The API
function “ApiOpenEx” has to be called to initialize the Application
Interface for the specified module, before any other API S/W Library function is
used for the specified module. This function establishes connectivity between
the Application Interface and the AIM board by calling operating system
routines to open the AIM board and initialize a shared memory area for
host-to-target communication.
For further informations
see the AIM Software “Reference Manual”.
3.1.8 Connecting the ANET1553 to the MIL-STD-1553 Bus
The MIL-STD-1553 Specification clearly defines the process of coupling subsystems to
the MIL-STD-1553 Bus.
This connection, called a stub, has the following two coupling options:
1) Direct coupled
2) Transformer coupled
In addition to these two standard methods of connecting to the bus as specified in the
MIL-STD-1553 specification, an AIM
Network Emulation Coupling mode is provided,
which allows a direct connection between a MIL-STD-1553 Remote Terminal and the
ANET1553 if the Remote Terminal is transformer coupled.
To physically suspend the ANET1553 MILBus signal-lines from the frontend TWINAX
connectors an AIM
Isolated Coupling mode is provided.
Further information about the coupling modes can be found in chapter 4.4.
All methods are described in this following sections.
