Please log in for more thread options Hello from the Eighth Doctor For my problem to be solved, (See the earlier threads concerning a strange networking problem.) I placed an e-mail to a company who made a gizmo which translates between COAX, and UTP. They claim the gizmo is now discontinued, but they have been saying that for about a year. <G>
Anyway while searching for solutions, and found them, I came across an e-mail embedded in a webpage regarding a crossover AUI cable described inside Tomi Enghdahl's terrific website. Basically it's two connectors wired together, instead of straight through, he's got the wires crossing over. Transmit on one to the receiver on the other, that sort of thing. Has anyone seen a something of a sort? ---- Gregg drwho8 atsign att dot net | ||||||||||||||||||||||||||||

There are active devices, the most famous one is called DELNI, which can be used to perform the function that you ask. I also used to have two and four port transceivers that, when properly terminated, would perform that function. My first work with thick ethernet used two and four port transceivers. One day I was having problems with a two port that had been working. After working on it for a while, I figured out that it failed when a transceiver cable was connected to the unused port without a host. I then built my own AUI terminators, and complained to the company that made them. There answer was to send us some AUI terminators. The four port version didn't have that problem, though. -- glen | ||||||||||||||||||||||||||||

I just finished using one of their search engines for the DELNI. I would have better luck wiring something of a sort. Does anyone on the NG have just such an item roosting in their equipment room, that they obviously do not need, and would be willing to part with, I'll pay shipping charges? And if your located in the tri-state area, (NY, NJ, CT), I'll take anything medium sized that's not needed as well, physically. Please e-mail for physical address. -- Gregg drwho8 atsign att dot net | ||||||||||||||||||||||||||||
