A vampire tap (also called a piercing tap) is a device for physically connecting a station, typically a computer, to a network that used 10BASE5 cabling. This device clamped onto and "bit" into the cable [1] (hence the name " vampire"), inserting a probe through a hole drilled using a special tool through the outer shielding to contact the inner conductor, while other spikes bit into the outer conductor.
The vampire tap usually had an integrated AUI ( Attachment Unit Interface) in the form of a DA-15 connector, from which a short multicore cable connected to the network card in the station ( host computer).
Vampire taps allowed new connections to be made on a given physical cable while the cable was in use. This allowed administrators to expand bus topology network sections without interrupting communications. Without a vampire tap, the cable had to be cut and connectors had to be attached to both ends.
