MWSR-100A Miniature Wideband CAIS Interface Module

The MWSR-100A module is a high-speed overhead module for use in the MWDAU-20XX product family. The module enables the MWDAU to operate as a wideband, stand-alone data acquisition unit with maximum bit rates up to 20 Mbps. The system works with I/O modules that are compatible with high-speed operation. The -1 version can also simultaneously operate as a CAIS remote slave unit for CAIS programming, data selection and synchronization when the optional MCIF-105 module is installed.

The -1 and -2 versions can have their major frames synchronized to an external source from 20 Hz to 1 kHz. The -3 version can have its major frame synchronized to an external one pulse per second source.

Additional Features

  • The -1 version provides an interface to the optional MCIF-105 module for CAIS programming, system audit, calibration signals, simultaneous sample, and data selection from the MWSR-100A PCM output
  • Converted data formatted into multiple identical RS-422 serial outputs
  • PCM format operates in the following synchronization modes:
    • Asynchronous operation using an internal clock synthesizer
    • Synchronous operation to CAIS major frame (-1 version) or external pulse (all versions)
  • Fully supported by TTCWare programming and setup software

Aerospace Instrumentation Brochure

Modern aerospace instrumentation systems can be highly complex, and it can be difficult to know how to meet program needs. It’s not unusual for requirements to change during a campaign and cause significant delays, and data must be captured reliably no matter what – otherwise expensive additional flights will be needed or months of program data could be lost. Read our brochure to learn how you can reduce your risk with commercial off-the-shelf (COTS) solutions.
