Data Sheet pdf
OVERVIEW
The IPM-ASCB-MRT provides four transceivers capable of supporting Avionics Standard Communication Bus (ASCB) versions A, B, C1, and C2 bus requirements.
Available as a 16-bit 32MHz single-size Industry Pack (IPack) module, the IPM-ASCB-MRT offers message scheduling and 32-bit time-tagging with a precision of one microsecond. An on-board 8MB SDRAM provides large buffering capabilities. Data transfer is controlled by polling or interrupt-driven software strategies to ensure optimal real-time performance.
The IPM-ASCB-MRT contains on-board coupling transformers for direct connection to the ASCB bus. The module supports three modes: a Bus Controller (BC), 4 Bus Monitor (BM) and up to 128 users, and the user addresses are software programmable. As an added convenience, the IPM-ASCB-MRT comes with 16 general-purpose DIO ports, which can be individually programmed as inputs or outputs.
Carrier Board Support
The functionality of the IPM-ASCB is further enhanced by the power of MAX Technologies’ line of intelligent multi- platform (PCI, CPC and 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.
