INTRODUCTION
1.1 General
This document comprises the Hardware User’s Manual for the ANET429-4/-8 or -16
standalone Ethernet based module. The document covers the hardware and software
installation, the board connections, the technical data and a general description of the
hardware architecture. For programming information please refer to the documents
listed in the ‘Applicable Documents’ section.
The ANET429 modules are members of AIM's new family of advanced Ethernet
connected standalone modules for analysing, simulating, monitoring and testing of
avionic data bus systems.
The ANET429 modules are used to simulate, monitor and inject protocol errors of
ARINC429 based data bus systems. The ANET429 offers an interface for up to sixteen
ARINC429 channels (RX or TX). Furthermore the interface implements trigger IN/OUT
functions, as well as 8 user definable Discrete I/O signals.
An freewheeling IRIG-B-122 compatible time code Encoder/Decoder allows the user to
synchronize to either the self-generated time code or the time code of an external board
with a resolution of 1µsec, to satisfy the requirements of 'multi-channel time tag
synchronization' on system level.
The ANET429 module is designed as a standalone module connected with an Ethernet
link to a host computer. An external power supply (wall adapter) is used to power the
ANET module.
The ARINC channels can be configured as RX or TX, and can be used in low or high
speed mode.
The hardware architecture provides ample resources (i.e. processing capability and
memory) to guarantee, that all specified interface functions are available concurrently
and to full performance specifications.
The key components of the ANET429 are the FPGA (which includes the ARINC429
core, the Processor-I/F, the Global RAM I/F), the BIU-Processor and the on board
Application Support Processor (ASP) which is based on a System-On-Chip (SOC)
hardware and running under an embedded LINUX Operating System.
The SOC hardware offers a built-in 10/100Mbit/s Ethernet interface, which is used for
the implementation of the host connection via a Standard Ethernet RJ-45 connector.
Furthermore the SOC also offers a built-in USB interface, which has been made
available to the user for mounting external mass data storage devices or use an
optional WLAN stick for wireless Ethernet operation
With 128MB Global RAM (shared between BIU, HOST and ASP) and 256MB of ASP
Local RAM plus 1GB of ASP Flash memory, the ANET429 Design offers enough
memory resources for various use cases and applications.
