PCI720 1Tx/1Rx  2Tx/2Rx PCI ARINC 429 Interface Card

ARINC 429 Interface card

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. In addition to this the card also contains, a microprocessor, a time tag register, on-card Filtering by Label and SDI, Optional 28-volt Event input, Optional RS232/RS422 converter, Data Acquisition FIFO's, and Dual Port memory for ease of interfacing to the PCI host bus.

• One or Two independent transmitters independent opto-coupled receive channels.
• Dual Port RAM interface for holding transmit sequence and ARINC 429 data tables.
• Independent High/Low speed selection of
  transmit data rates for each channel
• 28 bit Time Tag register (1mS resolution) for
  timing incoming data.
• Automatic High/Low speed adaption on received data for each channel with indication.
• On card filtering of incoming data by Label/SDI
  and Channel.

• 8 kilobytes of Acquisition FIFO with Interrupt and polling capabilities.
• Optional 28-volt opto-coupled Event input for marking data during data acquisition.
• Optional RS232/RS422 bi-directional Data Conversion on card.

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.
