The carrier board provides full data access to the IP module's I/O, ID and memory spaces. Each IP module can have up to 8MB of memory space. With full access to the programmable registers, users can easily configure and control the operation of the IP modules from the VMEbus. Also, up to two interrupt requests are supported for each IP module. The VMEbus interrupt level is software programmable. Individual passive filters and fuses on each IP module power supply line provide optimum filtering between the IP modules and the carrier board. Shielded SCSI-2 cable field I/O connections ensure maximum noise immunity.

The IP mezzanine's modular format enables multiple functions and high-density I/O on a single board to lower costs and save card slots. With its rugged design, open architecture, and high performance, the IP concept is ideal for a wide variety of I/O applications. Typical uses include data acquisition, process control, test & measurement, motion control, and network data communication.

To accommodate rugged, high-performance applications, the front-panel SCSI-2 connectors provide screw-down or spring latch connections that hold cables securely. And with support for 8MHz and 32MHz clocks, data can be processed at very high speeds. Prices start at $650 with extended temperature models (–40 to 85°C operation) available for an additional $100.

For connectivity with real time application programs, Acromag offers C libraries for the VxWorks® operating system. The libraries provide generic routines (source code included) to handle reads, writes, interrupts, and other functions. Demonstration programs enable the developer to quickly exercise the I/O modules before attaching the routines to the application program. This diagnostic tool can save hours of troubleshooting and debugging. Acromag has been developing and manufacturing measurement and control products for more than 45 years. They are an international corporation with a world headquarters near Detroit, Michigan and a global network of sales representatives and distributors. Acromag offers a complete line of embedded I/O products including bus boards, mezzanine modules, wiring accessories, and software. Industries served include military, aerospace, manufacturing, transportation, utilities, and scientific research laboratories.
