Not quite. The part with the 15-pin AUI connector is the trasnceiver. The
tap is the part of the transceiver that fits to the coax. In some cases,
the tap has sockets, and you fit it by cutting the coax, fitting plugs to
both cut ends, and plugging them in to the tap. Thats' not very convenient
when you want to connect to a network that's in use (the entire segment
will be ou of action while you do it and there's a risk of damage to other
transceivers as well), so tha alternative is a "vampire" tap. That's a
gadget that you fit by drilling a hole in the outer insulation and braid
(screen) of the coax, then applying the tap. It has a pn that penetrates
to the core conductor, and a part that makes contact only with the braid.
Then you fit the rest of the transceiver onto the vampire tap, and fit a
drop cable between the AUI connector on the transceiver and the AUI on your
machine.
