vampire tap
<networking, hardware> A device to connect a network node to an RG8 thick
ethernet cable without affecting other connected nodes.
A vampire tap has an interface box with a "V" shaped groove along one side. A
sharp needle protrudes from the center of the groove. The cable is clamped into
the groove by a grooved plate held in position by two thumb screws. With
sufficient practise, tightening the screws forces the needle through the cable
jacket and into contact with the cable's center wire while other spikes bite
into the outer conductor. The interface box has a 15 pin connector to connect to
the network node.
The vampire tap is often built into the transceiver, with a more flexible
multi-wire "drop cable" to connect the transceiver to the node.
