Abstract

Abstract The postage metering system includes a postage meter in bus communication with an external interface unit. The postage meter operates under the control of a programmable micro control system which is responsive to a number of postage meter program routines stored in the program memory of the meter micro control system. The postage meter also includes a principal communication port in bus communication with the micro control system and a keyboard also in bus communication with the meter micro control system for providing operator instruction to the micro control system. An external interface unit which includes a micro control system responsive to one or more of a program routines stored in the program memory of the external interface unit. The external interface further includes a postage meter port and a plurality communication ports. The postage meter port of the external interface unit is in bus communication with the principal communication port of the postage meter. The postage meter is programmed to be responsive to encrypted operator instructions inputted through the keyboard to enabling one or more of the postage meter program routines, and generating external interface unit instruction messages in response to the operator instruction. The external interface unit is programmed to be responsive to the instruction messaged from the postage meter to enable one or more of the external interface unit program routines.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 203 words
A postage metering system having a meter and an electronic interface unit (EIU), said meter being in bus communication with said EIU, comprising: said meter having meter program means for controlling the operation of said meter in response to one or more of a plurality of meter program routines and a principal communication port in bus communication with said program means; input means in bus communication with said meter program means for providing operator instruction to said meter program means said EIU having EIU program means for controlling the operation of said EIU in response to one or more of a plurality of EIU program routines, a meter port and a plurality of communications ports, said meter port being in bus communication with said principal communication port of said meter, said meter program means being responsive to said operator instructions for enabling one or more of said meter program routines, and generating EIU instruction messages in response to said operator instruction and communication said EIU instruction message to said EIU over said principal communication bus; and, said EIU program means being responsive to EIU instruction messages from said meter via said meter port for enabling one or more of said EIU program routines.
Claim 2
Dependent Claim 203 words
A postage metering system having a meter and an electronic interface unit (EIU), said meter being in bus communication with said EIU, comprising: said meter having meter program means for controlling the operation of said meter in response to one or more of a plurality of meter program routines and a principal communication port in bus communication with said program means; input means in bus communication with said meter program means for providing operator instruction to said meter program means said EIU having EIU program means for controlling the operation of said EIU in response to one or more of a plurality of EIU program routines, a meter port and a plurality of communications ports, said meter port being in bus communication with said principal communication port of said meter, said meter program means being responsive to said operator instructions for enabling one or more of said meter program routines, and generating EIU instruction messages in response to said operator instruction and communication said EIU instruction message to said EIU over said principal communication bus; and, said EIU program means being responsive to EIU instruction messages from said meter via said meter port for enabling one or more of said EIU program routines.
Claim 3
Dependent Claim 57 words
A postage metering system as claimed in claim 1 wherein said meter has a first mode of operation being responsive to said enabled meter program routine and a second mode of operation for enabling said meter program routines, said second mode being responsive to a particular one of said operator instructions for enabling said meter program routines.
Claim 4
Dependent Claim 33 words
A postage metering system as claimed in claim 2 wherein said particular one of said operation instruction is an encrypted instruction, and said meter program means having means for decrypting said encrypted instruction.
Claim 5
Dependent Claim 36 words
A postage metering system as claimed in claim 3 wherein said particular one of said operation instruction is comprised of an encrypted combination of a feature enabling set code, meter serial number and EIU identification number.
