Digi International, Inc. is an American Industrial Internet of Things (IIoT) technology company based in Hopkins, Minnesota. ^[2] 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 (BBSes). 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.

History

The company was founded in 1985 ^[3] and went public as Digi International in 1989. ^[4]

The company initially offered intelligent ISA/PCI boards (the 'DigiBoard') with multiple asynchronous serial interfaces for PCs. ^[3]

Patents

Digi International settled a patent infringement lawsuit with U.S. Ethernet Innovations LLC for $1.525 million in April 2013. ^[5]

In 2022, NimbeLink, a subsidiary of Airgain, filed a lawsuit alleging certain Digi products infringed on NimbeLink's Skywire cellular modems. ^[6] The U.S. District Court for the District of Minnesota found all patent claims by Nimbelink to be invalid in May 2024. ^{[7] [6]}
