ARCnet

(networking)
A network developed by DataPoint. ARCnet was proprietary until the late 1980s and had about as large a marketshare as Ethernet among small businesses. It was almost as fast and was considerably cheaper at the time.

ARCNET

(Attached Resource Computer NETwork) The first local area network (LAN) introduced in 1968 by Datapoint Corporation. Although ARCNET gave way to Ethernet for office networks, it is still used in industrial control applications.

Using the token passing access method, ARCNET connects up to 255 nodes in a star topology at 2.5 Mbits/sec over twisted pair or coax. ARCNET Plus offered 20 Mbits/sec but came out after Ethernet was becoming entrenched. Like Ethernet, ARCNET is a data link protocol that functions at layers 1 and 2 of the OSI model. See token ring network, data link protocol, Ethernet and OSI model.

The solution would be a system that integrates the complete spectrum of a building's management functions into one system supporting a mixture of operating systems--DOS, Windows, OS/2, UNIX, AppleTalk--with different network protocols (Ethernet, token ring, Arcnet) and a whole host of different types of text or graphics based systems interfacing into a flexible, reconfigurable system that addresses key issues.
The system can be configured for Ethernet, ARCNET or Token Ring networks.

We picked ones that were in common use at the time (ARCNET, Ethernet, EIA-232, and EIA-485) and that were acceptable to the manufacturers because they were already familiar with them.
