Powerful capabilities for avionics maintenance

The DATATRAC 650H is a single channel ARINC 629 data bus analyzer housed in a rugged hand held ABS plastic enclosure. Basic receive and transmit functions are implemented along with a general record mode and a powerful breakpoint mode. The standard RS-232C port is used for downloading real time or recorded data and for uploading new label/word definitions. The standard DAC port can be used to provide a trigger pulse or to drive recorders or instruments. PC software is available to aid the user in defining their own data definition table(s). The large graphical display and integrated keyboard provide an informative and intuitive user interface expected in larger bench units.
