The GPS-101B card provides IRIG-B time code capability as well as GPS position, velocity and course data to the EDAU/ CDAU/WDAU-2000 data acquisition unit. The card can be placed in either a master or remote unit operating at up to 20 Mbps and will provide time code capability for the cards within that particular chassis, allowing per-word or per-message time tagging capability for I/O cards in the chassis that acquire bus data.
