What kind of wire? UTP? Shielded? Gauge?

Further no information except component spec. Can anyone tell me if there are general rules for connectors so I can put an s-paramater model/ spice equivalent circuit based on mechanical information like Pin length and Pin distance. And then the Twisted pair wire in between. Are there sides that have models for cables. Use the characteristic impedance as a base? But what is the loss over such a long distance and the cross talk between the cabels? And the only thing I have is mechanical information and the just mentioned Impedance. I have some ideas but I think you have better. Experience with htis Thanks in advance, Laury ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List technical documents are available at: http://www.si-list.net List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu ------------------------------------------------------------------ To unsubscribe from si-list: si-list-request@xxxxxxxxxxxxx with 'unsubscribe' in the Subject field or to administer your membership from a web page, go to: //www.freelists.org/webpage/si-list For help: si-list-request@xxxxxxxxxxxxx with 'help' in the Subject field List technical documents are available at: http://www.si-list.net List archives are viewable at: //www.freelists.org/archives/si-list Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
