ABSTRACT:
A hand held data entry terminal that, upon initialization of a data entry program downloaded from a host computer, is capable of capturing product data, through either a terminal scanner or a data entry keypad, at locations remote from the host computer. A data entry program is downloaded to a battery-powered data entry terminal from a central host computer via an RF data transceiver located in the terminal. If the terminal scanner is functional and the product contains the necessary coded representations of data, the scanner may be enabled, through a first trigger located on a terminal handle, to scan the coded representations of data. Alternatively, the terminal operator may enter alpha
umeric product data through the terminal keypad. The data entry program contains a stack of key definition tables for the terminal keypad, allowing the terminal to be designed with a minimum number of data entry keys and a terminal display of maximum size. If the keypad mode of data entry is used, the terminal operator may scroll through the alternate key definition tables by using certain command keys, or via a second trigger located on the terminal handle, to select the proper key definition table for a particular mode of data entry or to select a particular data entry command. Regardless of the mode of data entry used, the data entered into the terminal is stored in a buffer at the terminal. Once all data has been entered into the buffer, the processor, upon receiving a SEND command, sends the data to the host computer via the terminal RF transceiver.
