This apparatus integrates essential hardware connectivity functions designed to interface with a
Maestro Host Computer and installed National Instruments PCIe-6363 interface board and the
Plexon Multi-Channel Acquisition Processor. These functions are: Analog Input, Analog Output,
Digital Input, Digital Output, Plexon/OmniPlex Interface and Reward Delivery.
This interface serves as a breakout panel for the analog signal lines. It also buffers the input lines,
providing the data acquisition board with an additional layer of protection against power surges,
short circuits, or bad wiring in the laboratory apparatus.
The digital I/O interface is more than just a “breakout panel" for the 16 digital inputs and 12 digital
outputs of Maestro's DIO event timer device. The interface also houses one or more modules that
perform critical tasks in the experiment rig.
This DIO feature was conceived in the Lisberger lab as part of a scheme to integrate Maestro's data
stream with the Plexon Multichannel Acquisition Processor (Currently OmniPlex) and provides real-time
spike sorting across multiple electrode channels.
functions by Maestro writing to this device and delivering a pulse whose
duration in milliseconds
is specified by a 12-bit value. This pulse ultimately drives a solenoid valve that gates the flow of liquid for reward
