A system and method for interfacing a data acquisition device to a host
device via a plurality of interfaces are provided. The present invention
is enabled by a multi-interface controller which enables the data
acquisition device to interface to a plurality of host devices having
different interfaces e.g., RS232, USB, keyboard wedge, IBM4683, wand
emulation, synapse, undecoded, etc. The interface controller includes a
microcomputer for translating received data from the data acquisition
device and outputting a host device type signal; and a switching circuit
for electrically coupling the microcomputer to the at least one host
device based on the host device type signal and transmitting the received
data to the host device.
