Digi International


Digi International, Inc. is an American Industrial Internet of Things technology company based in Hopkins, Minnesota. Founded in 1985, they were best known in the early 1990s as a manufacturer of multi-line serial data serial cards for PC clones, allowing these machines to run multi-line bulletin board systems. As this market began to wind down with the rise of the internet in the late 1990s, Digi began to concentrate on network attached devices and industrial monitoring.
