The datalink library allows sending information to the Timex DataLink watches. The original datalink library supports the DataLink models 70 , 150 and 150 S watch and has been extended to work with the DataLink Ironman Triathlon watch. It has been tested with the SVGA output on the Ironman watch only, other output devices and other watches may or may not work, I have no reports either way. The display must be a CRT display (not a LCD).
