I want to thank all of you for your responses. Too much to think about! Someone mentioned to me that CAT5 and RJ-45 connector should work fine with a 100 ohm termination resistor. Any opposing views? At least this is something our guys know how to make up! Again, thank you for your help. ------------------------------------------------------------------ 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 archives are viewable at: //www.freelists.org/archives/si-list or at our remote archives: http://groups.yahoo.com/group/si-list/messages Old (prior to June 6, 2001) list archives are viewable at: http://www.qsl.net/wb6tpu
