The DT400H Databus Analyzer is a lightweight handheld ARINC 429 databus analyzer that provides the same features as the full-sized DT400. This device provides breakpoint troubleshooting mode, 16-label recorder, 128-label transmitter, RS-232C port, D/A conversion, and a Williamsburg protocol analyzer. The LCD backlit display is sunlight readable and can operate for over six hours on battery power. The large 16-line display provides two main advantages: Bite messages and the ability to simultaneously display multiple labels. The screen accommodates the ARINC 604 normal or inactive mode formats and 350-label maintenance information can be read using a pre-stored database for 700-series equipment. In addition, the user can record up to 240 screes for later download to a PC or printer. BITE mode supports systems on the 737-300, 747-400, MD-11, and A320/330/340. Data from two buses can be displayed in nine formats (hex, binary, ASCII, engineering units, user programmed, etc). Database conforms to 429-15 and includes Boeing labels for AVM, EIS, EICAS, FSEU, and FQIS.
