BioStim Computer Interface
It is an alternative equipment to substitute the BioStim Controller in cases, when a computer software is used to generate the sequence of stimulating pulses. BioStim Computer Interface has got a universal connector compatible with any Stimulus Isolator manufactured by Supertech Instruments. BioStim Computer Interface has got a built-in power supply unit optimized for the Stimulus Isolators and it has two universal TTL-compatible digital input connectors. Its TTL inputs are configured in logical OR function internally. The TTL gold standard describes the voltage and load specifications of the inputs and outputs of a logic system, what is supplied from 5V. Nowadays most of the microcontrollers and logic systems use 3.3V of internal supply voltage. The logic signal inputs of the BioStim Computer Interface are universal, they accept the logic levels of the 3.3V, non-standard-TTL systems correctly with optimal noise margins, too.
Basically BioStim Computer Interface realizes (by hardware) the DC via Control function (see later in this description) of the BioStim Controller. If an appropriate software is used, what can generate the stimulating pulse trains, it is not necessary to order a BioStim Controller at all, it is enough to use the BioStim Computer Interface instead. The disadvantage of this arrangement is, that a fast computer and a time-critical multitasking DAQ software is necessary to be used. An independent, universal, stand-alone stimulator can be formed only by using the BioStim Controller.
