No definitely NOT! Something is wrong!
The resistance is FAR TOO LOW!
You have a short in the cable somewhere.
Put a terminator at one end. Disconnect the connectors at the computer so
you have a "straight line".
[-+---------------+--- ]
Where "[" are the terminators
The "+" represents the T connectors
Measure the resistance at the open end. It should be the value for the
terminator at the other end PLUS a few ohms introduced by the cable... I.E.
54 ohms for a 50 ohm ThinNet resistor...
Now do it the other way.
Now put both terminators on and measure at the T.
You should get 1/2 the resistance of the two terminators plus the resistance
of the cable... I.E. 28 ohms or so if you are using 50 ohm terminators...
9 ohms is far too low and will cause the cards to see the cable as "open".
Also did you set up the cards to utilize 10Base2 instead of 10BaseT?
Most cards come with 10BaseT set as a default and have to be adjusted with
software which reflashes the card's settings...

Subject: RE: [newbie] repost : lan problems
jose,
today i tested my wiring :
over the 15m BNC cable (with both T and resistors connected) i have 9 ohm
resistance.
T-conns are ok.
resistors have 58 ohm.
are this values ok ?
