The AT-PCI-MPAC family of products provides the highest level of performance and flexibility on various hardware interface architectures and custom platforms. It offers an ideal platform for test & evaluation of avionics systems and sub-systems, as MIL-STD-1553B, ARINC429, RS-232, RS-422 and Digital I/O channels are integrated in this card. While the UART and DIO features are provided as standard, the user has a choice of configuring the card to support either MIL-STD-1553B or ARINC429 or both. The card provides one dual redundant channel of MIL-STD-1553B and 2 ARINC429 controllers. Each ARINC429 controller provides 2Tx and 4Rx channels achieving a maximum of 4 Tx and 8 Rx channels. The MIL-STD-1553B functionality is available with a choice of DDC controller and ARINC429 is also available with DDC controller. The AT-PCI-MPAC is integrated with powerful software that reduces development time. All data bus functionality is supported by our advanced API (Application Programming Interface).

Overview

HARDWARE

PCI Card
The AT-PCI-MPAC is a ¾ length card meeting PCI Local Bus Spec.Rev 2.1. It comes with a standard 62-pin D-type connector for all I/O connectivity.

PCI Plug & Play
The AT-PCI-MPAC card provides full PCI plug & play compatibility greatly simplifying the installation of the card into a PCI compliant system. Both the BIOS and the OS can determine the memory and interrupt resources to be used by the card. As PCI interrupts are sharable, the OS can assign an interrupt of any PCI card in the system in the event of no free interrupt resources being available. The driver handles all such events.

I/O Connectivity

UART Channels
The AT-PCI-MPAC cards provide two standard serial UART ports supporting RS-232 and RS-422 interfaces. These are capable of a maximum asynchronous baud rate of 115.2 Kb/s.

Digital I/O Channels
Additional to the serial I/O capabilities, the AT-PCI-MPAC is equipped with TTL/CMOS level digital I/O channels. It comes with 16 general-purpose digital I/O channels. These are pre-configured as 8 inputs and 8 outputs. These can be used to generate an interrupt on any type of level shift event.

MIL-STD-1553B Interface – Optional

The AT-PCI-MPAC card’s single function MIL-STD-1553B architecture emulates a Bus Controller or 31 Remote Terminals or Monitor Terminal modes. Polling and interrupt generation is also provided. The 1553B Channel comes with 64K words (DDC) static RAM.

Transformer and Direct Coupling

The cards are provided with the option of using them either in the transformer mode or in the direct mode. A jumper is provided on the cards to select the mode. The default connectivity is transformer-coupled mode.

ARINC429 Interface – Optional

The card can be configured with up to 2 ARINC429 controllers. Each controller is configured with 2Tx & 4Rx channels and has 128 x 32 bit static RAM. Look-up tables loaded into the RAM enable the module receive circuitry to filter and sort incoming data by label and destination bit. It also provides multilevel data specific interrupts or hardware triggers.

SOFTWARE

The AT-PCI-MPAC software includes:
> Bus Monitor
> Drivers & APIs

Bus Monitor

  • Record and replay of data
  • Replay with rate selection
  • Message identifier
  • Multi console at a time
  • Bus ideal time analyzer
  • Filtering option up to sub address
  • Message sampling option

Drivers & APIs
The AT-PCI-MPAC card comes with a powerful set of library functions to access the entire I/O functionality. The drivers are designed in a modular fashion consisting of component functions & application functions. The user’s test program can be developed with few calls to the driver, by using the set of Application functions provided. Drivers and high-level API libraries for Windows XP, Linux and RT-Linux are available depending on the platform. Sample programs are included with the card.
