    I called Farallon about this.  The answer they gave me was that all one
had to do was raise the DTR line (I think) high.  The MacRecorder draws
power from this.  Then, the data, sampled at 22,000 Hz, comes in the serial
port.  Slower sampling rates are implemented in software, by throwing out
extra data.
    Hope this is enough to help you.
