PCI ARINC 429 CARD
Part Numbers: YED/PCI720
General features
The PCI-720 ARINC 429 Interface
card is a half-length PCI version 2.1 compliant interface card. Depending upon
the options at time of ordering, the card will comprise of one or two
independent transmitter channels that function as Bus Traffic Simulators and
one (PCI-720/1) or two (PCI-720/2) independent receiver channels to provide
advanced Bus Monitor and Analysis functions. The functions on all four
channels are available concurrently at full performance level. The card
incorporates a microprocessor, a time tag register, on-card
Filtering by Label and SDI, Data Acquisition FIFO's, and Dual Port memory for ease of
interfacing to the PCI host bus.
This card also has an option of
fitting RS232/RS422 data translators. A typical example requirement would be
to monitor data from an RS422 GPS signal source using the PC COM port
(RS232). An
optional 28-volt Event input is also provided. Note that these features must
be requested at the time of order as they are not available on the standard card.
Please contact YED for further details.
Transmit Operation
In Simulation
mode, the PCI-720 executes autonomously instructions held in the interface
memory and will perform cyclic and one shot modes of operation. Label
repetition rate, minor and major frame rates are completely controlled at the
board level, which significantly reduces the host PC overhead. The output rise
and fall time of the output signals are switchable to adapt to the selected
transmit frequency. For each simulated ARINC-429 Transmitter all Labels can be
generated and the label data and descriptors can be updated during simulation
at any time without corrupting the transmission. Multi-SDI transmissions of
the same label are possible and variation of individual Label/SDI descriptors
in real time are also permitted.
Receive
Operation
The opto-coupled
receivers provide for comprehensive Bus Monitoring and Data Acquisition to
hard disk. All received data is time tagged to 1mS resolution. All Label/SDI
filtering is performed on the card and data captured from each bus is stored
in 8k of FIFO memory, which is off-loaded by the PC at regular interrupt
intervals. The card can be programmed to generate interrupts when the FIFO
reaches the half-full point or the status of the FIFO can be polled.
Windows
Real Time Simulation and Data Bus Analyzer software
The card is supplied with a full function Windows
95/98/NT4/2000 (later operating systems, including XP, will also be supported
- check with YED
for further information) Real Time Simulation / Data Bus Analyser package providing a
complete turnkey solution.
All data is displayable in engineering units (standard or
custom) with labels shown in octal. All data fields are user definable.
Multiple fields within a data word are possible, i.e. Discrete/Flags mixed with
a Binary field within a single word. Currently, engineering formats are
available for Signed binary, Unsigned binary, 2's compliment, BCD and Discrete
data.
An ARINC 429 Analyzer and simulation software
package is available for this card.
