MIRG-220B

The MIRG-220B module provides IRIG-B time code capability to the MEDAU/MCDAU/MWDAU-2000 miniature data acquisition unit. The module can be placed in either a master or remote unit and will provide time code capability for the modules within that particular stack. The module accepts an external IRIG-B, AC, or DC time source for frame time tagging purposes, and in addition, provides per-word or per-message time tagging capability for certain I/O modules in the stack that acquire bus data (e.g. 1553, ARINC-429, RS-232, etc.).

The MIRG-220B module also provides an IRIG-B DC time code output for cascading purposes. All encoded time words furnished by the MIRG-220B module comply with IRIG-106-96, Chapter 4 requirements for “high time”, “low time” and “micro time” formats. The module also has a built-in Real Time Clock (RTC) with a variety of battery backup options and an ADC to measure and encode the internal MEDAU-2000 system temperature and voltage rails within the host MEDAU-2000 Encoder.
