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. (2004-08-25)
