ANSI/ATA 878.1 or ARCNET. Master Slave/Token Passing or MS/TP. Point-to-Point or PTP. LonTalk - proprietary technology developed by the Echelon Corporation. FIRE Ethernet Pros Cons Internat’l standard. High cost. Exists in most bldgs. Distance limitations. Ease of interface to PC’s. No develop. tools. Non-Deterministic (contention based). Very fast comm. (10 to 100Mbps). Transport media (unshielded twisted pair (UTP), coax, fiberoptic). FIRE ARCNET Pros Cons ANSI standard. Single source chip. Deterministic. Scaleable speed. Too costly for low-end unitary controllers. No develop. tools. Distance limitations. High performance; medium cost. Very fast comm. (150K to 7.5Mbps). Transport media (UTP, coax, fiberoptic). FIRE MS/TP Pros Cons ANSI standard. Deterministic. Low cost. Implementation in single chip microprocessors. Transport media (EIA485). Limited speed (9.6K to 76Kbps).
