The invention includes a main circuit board which is coupled by a 68 pin SCSI-2
connector to a National Instruments DAQ (PCI-6024E or equivalent) which resides
in an expansion slot of a personal computer running National Instruments LABVIEW
software which has been modified to include a custom communications driver. The
main circuit board includes a communications module, a manual control module, a
function generator, an analog I/O module, a current amplifier and frequency calibration
module, and an address and status module. The main circuit board is also provided
with a first edge connector for receiving a removable protection board which has
a second edge connector for receiving a removable prototyping breadboard. The protection
board protects the main circuit board and the DAQ from circuit faults on the prototyping
breadboard. The main circuit board communicates with the DAQ via 8 digital I/O lines.
