  An instrumentation prototype for acquiring high-speed transient data from an
array of high bandwidth antennas is presented. Multi-kilometer cable runs
complicate acquisition of such large bandwidth radio signals from an extensive
antenna array. Solutions using analog fiber optic links are being explored,
though are very expensive. We propose an inexpensive solution that allows for
individual operation of each antenna element, operating at potentially high
local self-trigger rates. Digitized data packets are transmitted to the surface
via commercially available Giga-bit Ethernet hardware. Events are then
reconstructed on a computer farm by sorting the received packets using standard
networking gear, eliminating the need for custom, very high-speed trigger
hardware. Such a system is completely scalable and leverages the hugh capital
investment made by the telecommunications industry. Test results from a
demonstration prototype are presented.
