Product Description

The Cyclone16/550 is a non-intelligent, low cost alternative to the Cyclone16/32 Serial Expansion Unit. If you don't need a board that has the fastest data rates, or the largest FIFO's, the Cyclone16/550 is for you!

You'll see that the Cyclone Family Serial Expansion Units are unlike any other multiport board on the market today. These new products are the solution to Internet and Intranet Connectivity!

Cyclone16/550 Features:

  • 16C550 Non-intelligent UARTS
  • Data rates up to 115.2 Kbps on all ports! 16 byte transmit/receive FIFO's
  • Flexible addressing selections. There are 8 addressing modes (6 vertical and two horizontal modes) to choose from.
  • Flexible IRQ selections.
  • Operating systems supported: WindowsNT, Windows95, Linux, FreeBSD, BSDI, OS/2 (using SIO) and DOS.
  • Compatible with all popular BBS/Internet software: PCBoard, MajorBBS, Worldgroup, , Metaworlds, Esoft, Durand Mindwire, Wildcat, and much more!
