Abstract
Abstract A portable, hand-held data terminal of modular structure includes a base module with a keyboard and a display screen. A data collection and communications module includes a stacked arrangement of a communications interface main circuit board, a radio and a laser scanner assembly which are housed in a housing shell which is attachable to the base module. The radio is mounted in spaced relationship to one side of the main circuit board, while the laser scanner assembly is mounted to the other side of the main circuit board. A support frame and a plurality of ground planes in the sandwiched main circuit board and a routing circuit board form an RF cage for shielding RF interference which may be generated by the radio.
