1.1 General
This document comprises the Hardware User’s Manual for the AMCX429-4/8/16/32 PCI
Mezzanine Card, consisting of the AMCX429-4/8/16/32 electronic module. The document
covers the hardware installation, the board connections, and a general description of the
hardware architecture and the technical data of the AMCX429. For programming
information please refer to the according documents listed in the 'Applicable Documents'
section.
The AMCX429 module is a member of AIM's family of advanced PMC-Bus modules for
analysing, simulating, monitoring and testing of avionics data bus systems.
The PMC module is designed to be plugged on either, a host carrier board to adapt to
standard PCI, VME or CPCI busses, or on an embedded host computer with PMC ports.
The AMCX429 provides four, eight, sixteen or thirty-two fully configurable ARINC429
channels whereby the four and eight channel board is an assembly variant of the
AMCX429 sixteen channel board. Each channel can be individually configured by
software as a transmit or receive channel with shared front panel connector outputs and
inputs.
Due to desiderate amount of IO pins, the IRIG Input and Output on AMCX429-32 variant
is only available on Front-IO. The Trigger feature is limited to only one Trigger Output line
on Front panel Connector on AMCX429-32. Trigger Inputs and Discrete IO are not
supported on 32 Channel ARINC mezzanine modules.
The conduction cooled AMCX429-32 version has no Trigger IOs at all due to the limited
pin count of the Rear IO connector.
On transmit channels the AMCX429 acts as an autonomously operating bus traffic
simulator, supporting multiple modes of transmission sequencing. Full error injection
capabilities are available, whereby the error injection is programmable individually for
each channel and label. For a special transmission operating mode the parity bit can be
used alternately as an additional data bit. The rise and fall time of the bus signals are
individually programmable by software for each transmit channel.
For the receive channels the AMCX429 provides an advanced monitor and analyser
function, with unique on-board error detection, triggering and filtering capabilities.
Both functions are available concurrentlyand independent from each other. Thehardware
architecture provides resources to guarantee the performance of one function is not
affected by the current load of other function. The rise and fall time of the bus signals are
individually programmable for each receive channel. To adapt todifferent transmit speeds
the transmission rate can be varied in discrete steps between approximately 90 and
120Kbit on the high speed bus and between 11.5 and 16.0Kbit on the low speed lines.
The discrete steps are global for all channels.
