Response 1: *
Default Setting: /K2[CR]

The iPort/AFM clock rate for standard commands is controlled by the oscillator
crystal we use on our microcontroller. This crystal has been selected to give accurate
RS-232 baud rates, as the RS-232 baud rate must exactly match the rate used by the
host computer. Master I2C clock rates are the fastest possible given the required
crystal frequency. Slave I2C clock rates are driven by the external master device,
with possible clock-stretching as required to store or retrieve message data.
