Method and apparatus for inserting data into electronic taximeters from a central computer temporarily connected to a local terminal
First Claim
1. A method of entering data, in particular charging data, into electronic taximeters, wherein a table of said data corresponding to various different towns is recorded in the memory of a central computer which is accessible over a telecommunications network, wherein taximeters are connected one-by-one via an adaptor device to an I/O connector of a terminal, wherein said terminal is connected to said central computer via a telecommunications line, wherein the caller is identified by keying in a personal password using the keyboard of said terminal, and wherein the transfer of said data into said taximeter is called to take place by the caller pressing an appropriate key on the terminal.

Abstract
In order to introduce data, and in particular charging data, into the memory of a taximeter, the taximeter is connected to an adaptor which is in turn connected to the I/O connector of a local terminal which is connected to a central computer over a telecommunications network. The adaptor includes a microprocessor which is programmed to recognize the nature of the packets of data received from the central computer, to transcode the data, and to transfer the data into the taximeter memory.
