ipm-429

The IPM-429 is a standard IndustryPack (IPack) module that can be used with MAX Technologies’ PCI, CPCI, VME and PXI intelligent carrier boards. The IPM-429 module can also be used with MAX Technologies’ MAXVME-6400 VME-64x dumb carrier board or a third party carrier boards supporting 32-MHz IPack modules.

Additional configurations and accessories are available. Please contact us to inquire.

OVERVIEW

The IPM-429 provides a high channel density solution to your ARINC 429 Avionics Databus requirements. Available as a 32MHz single size Industry Pack (IPack) module, the IPM-429 offers message scheduling and time-tagging with a precision of one microsecond. On-board transmit/receive buffers have programmable almost-full/almost- empty thresholds, which fully support both polling and interrupt-driven software strategies to ensure optimal real-time performance. The IPM-429 transmitters are short-circuit protected and offer programmable parity, word length, bit-rate and slew-rate. Receivers can be programmed to filter incoming messages based on their ARINC 429 labels. In addition, receivers can detect parity and short-word errors, and can be configured for internal loopback.

The ELB option offers automatic external loopback verification on transmission, which provides continuous verification of the transmitted data.

As an added convenience, the IPM-429 comes with 8 general-purpose DIO ports that can be programmed to toggle during the transmission of individual message words.

Carrier Board Support

The functionality of the IPM-429 is further enhanced by the power of MAX Technologies’ line of intelligent multi- platform (VME, PCI, CPCI, PXI) carrier boards. All modules and carrier boards are synchronized and time correlated to 32-bit microsecond-resolution.

Software Support

The MX-Foundation library provides high-level abstraction of hardware and allows to easily control mixed protocols and I/O modules on one or multiple carrier boards.
