ipm-async

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

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

OVERVIEW

The IPM-ASYNC provides a high-channel-density solution to your ASYNC RS422/485 and CSDB Avionics Protocol requirements. Available as an 8MHz single-size Industry Pack (IPack) module, the

IPM-ASYNC 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-ASYNC transmitters are short-circuit protected and offer programmable parity bit, stop bit, word length, and bit-rates up to 1 Mbps. Receivers can detect parity, framing errors and can be configured for internal loopback. As an added convenience, the IPM-ASYNC comes with 8 general-purpose discrete differential
I/O lines, four of which can be programmed to toggle during the transmission of individual message words.

Carrier Board Support

The functionality of the IPM-ASYNC 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.
