Abstract:
A wireless communications module, comprising:a) a support having a base lying in a first plane; b) a data acquisition system including a light source on the base for directing a light beam at an indicium for reflection therefrom, and a light detector on the support for detecting light reflected from the indicium and for generating an electrical signal corresponding to the indicium; c) a first printed circuit board on the support and lying in a second plane generally orthogonal to the first plane; d) drive circuitry on the first printed circuit board for driving the light source; e) a second printed circuit board on the support and lying in a third plane generally orthogonal to the second plane and generally parallel to the first plane; f) signal processing circuitry on the second printed circuit board for processing the electrical signal to obtain a processed signal; and g) transmitter circuitry on the second printed circuit board for transmitting the processed signal at radio frequency away from the support.
