We discovered a while ago that you can actually simulate vampire taps
using a thin ether , T-connectors and standard in-line 3-com Xceivers.
What you do is as follows
Thin ether -> ____________________ ____________________
T-connector -----> T
BNC-N crossover ----> I
__I__
3-Com Xceiver -----> | |
|___|
I
The lower N-connector on the 3-com stays unterminated!
Max permissible length from ether center conductor to 3-com far end
is probably around 10 ".
A screening cover lid might be a good idea for the free end of the
Xceiver.
No extensive tests were performed, but a couple ( 3 ) of stations seemed to
work ok, never jamming the ether while {,dis}connecting stations.
This ( if it really works ) removes one difficulty with thin ether.
