Problem with wiring a networking device or devices |
|
|
Hello from the Eighth Doctor
Does any company that any of you know of make a device to translate Coax/BNC
connector based networking to 10BASE-T?
I have here a DEC Terminal Server model 90L+, it works, I can see it working on
the screen of my host. I need to connect it to my LAN, which is a 10BASE-T based
one. I have the AUIs that contain the same connectors, and have the DB15
connectors at one end, (Your right Rich I have cursed at those things, but never in
your direction.). I also have the same AUIs from Cabletron, and it seems they might
have all been made by AMP since the design matches the one the company has
online. I also have the 10BASE-T to AUI connecter, from Synoptics. One of those
is normally connected to my network for my VS 3100 Model 76.
However I don't have the beast I've described. I also have a hub made to connect
four computers together via the same AUI described method. I'm thinking I can
kludge together something around that hub, since its an active device, but the
problem lies on the connector for the DEC TS, it has attached to one end of T
connector a termination resistor. Someone from Digital Networks suggested that
step.
And that's my problem.

We would use one of our old hubs which has 8 (or 12) 10-base-T ports
and an AUI port.
Simply slot a coax transceiver into the AUI port, and away you go.
Not sure if one can still buy such things, but we've got several
festering on the shelf, as must many other folks whose networking goes
back a decade or so. |

Nice. Expect that's there, and I'm here. I am based in the US, despite my
"borrowing" of the Doctor's names.
That is the solution I need. Who makes the thing?

Well, we've got several, some from 3com and some from AT (Allied
Telesyn), but they're ancient, I doubt that you could buy them now.
Try a google for the terms 10baseT and AUI, it brings several hits
that appear to point to current products that you could buy.
How about this http://www.cir.com/pc/pc.htm#networkhubs
8 Port Mini Network Hub w/ BNC & AUI $69.00
You'd need your coax transceiver too, of course, but maybe you already
have one. |

Allied-Telesys (I may not have the name exactly right) made match-box
sized AUI-UTP and AUI-TW transceivers that cost about $20 the last
time I bought them, may years ago. A few months ago I came across them
in the net womewhere.
Googling just came up with this page that caims that someone still sells
vampire taps. They may have other uninteresting stuff for sale.

Most of the 10 Mb hubs that were common a few years back had several 10baseT
connectors and one BNC connector. I've got one here. You may still be
able to find one, either new or used. |

Froogle "10baset bnc hub" and you'll get around 90 hits, starting at 4
bucks.

I am based in NYC, Queens in fact. What's the shipping costs from where you are

I'll throw a wrench in the works, are you sure it's coax ethernet (thinnet,
10Base5). There was/is a thing called DEC-Net which looks like coax
ethernet....But isn't.

DECnet is a networking protocol, like IP, that can be transported
on ethernet, among other layer 2 protocols.
As DEC was part of the original DIX (the D part) ethernet, it would
seem likely that it was ethernet.
It seems that the 90L+ is LAT, the non-DECnet, non-IP protocol DEC
used for terminal servers.

DEC-Net is ethernet. DEC was the "D" in DIX, with Intel and Xerox as the
originators of ethernet. |
