I have a Thinwire Ethernet wiring question. I know that each segment has a maximum length of 185 meters and 30 devices. The question is the definition of 'device'. We wire an office group by chaining a segment thus: >-------------+ +-------------> Ethernet in | | Ethernet out | | +--------+ | | | | Wall box | | | | +--B--B--+ B = BNC connector crimped inside box A A A = BNC twist-on | | | | (2) 10 foot cables +--+ +--+ | | +--ATA---+ T = BNC T-connector We always thought this counted as one 'device'. We just learned that each BNC connection should be counted as one 'device'. Is this true? Is the above 1, 3 or 5 devices? Thanks for any info, -Bruce -- Bruce Tanner (213) 860-2451 x 596 Tanner@Cerritos.EDU Cerritos College Norwalk, CA cerritos!tanner

Every place you can place a node is counted. Every BNC "T" connector. It doesn't matter what you plug in: a PC Ethernet card, a UNIX mini, a BNC-to-twisted pair MAU, or a repeater. Each device connected to the coax is to be counted as a device connected to the coax. Howard Stateman Systems Support Engineer Intelligent Networks Operation, Palo Alto howeird@hpspdra.spd.HP.COM

You don't have to plug a device into it. -- Lyle 508 967 2322 lws@wang.com Wang Labs, Lowell, MA, USA
