Abstract
A bar code scanner suitable for use with a variety of different host terminals includes a microcontroller whose frequency of operation is changed as a function of the host terminal to which the scanner is connected. Where a particular host terminal is operable at a lower rate the microcontroller may be operated at a lower frequency to reduce the power consumption of the scanner.
