Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
A system for making a written record of data received in any selected one of a plurality of communications codes, said system comprising: a communications interface constructed in accordance with one communications code; a printer interface; a printer connected from said printer interface; and one module corresponding to said one code and movable independently of said printer interface, said module being connected between said interface to convert said one code to a set of signals to operate said printer, said module and said printer interface having mating portions of a quick detachable electrical connector such that said module may be connected to said printer interface or replaced by another module with a mating connector and corresponding to another communications code.
Claim 2
Independent Claim
120 words
A system for making a written record of data received in any selected one of a plurality of communications codes, said system comprising: a communications interface constructed in accordance with one communications code; a printer interface; a printer connected from said printer interface; and one module corresponding to said one code and movable independently of said printer interface, said module being connected between said interface to convert said one code to a set of signals to operate said printer, said module and said printer interface having mating portions of a quick detachable electrical connector such that said module may be connected to said printer interface or replaced by another module with a mating connector and corresponding to another communications code.
Claim 3
Dependent Claim
30 words
The invention as defined in claim 1, wherein a data source is connected to said communications interface to deliver the self-same one code thereto to which said one module corresponds.
Claim 4
Dependent Claim
25 words
The invention as defined in claim 2, wherein said one code is the conventional RS232C code and said other code is the conventional Centronics code.
Claim 5
Dependent Claim
25 words
The invention as defined in claim 2, wherein said one code is the conventional RS232C code and said other code is the conventional IEEE code.
Claim 6
Dependent Claim
25 words
The invention as defined in claim 2, wherein said one code is the conventional Centronics code and said other code is the conventional IEEE code.
Claim 7
Independent Claim
169 words
A system for making a written record of data received in any selected one of a plurality of communications codes, said system comprising: at least first and second sources for producing data signals in first and second different respective communications codes; first and second communications interfaces connected respectively from said first and second sources and corresponding respectively to said first and second codes; first and second modules respectively connected from said first and second communications interfaces, said first module being constructed to produce a set of output signals the same as that of said second module; a printer interface; and a printer connected from said printer interface, said printer interface including an electrical socket, said first and second modules having first and second plugs, each of said plugs being constructed to mate with the self-same said socket, said first and second modules being alternately connectible with said printer interface to convert said first and second codes, respectively, and alternately to the same set of signals to operate said printer.
Claim 8
Independent Claim
169 words
A system for making a written record of data received in any selected one of a plurality of communications codes, said system comprising: at least first and second sources for producing data signals in first and second different respective communications codes; first and second communications interfaces connected respectively from said first and second sources and corresponding respectively to said first and second codes; first and second modules respectively connected from said first and second communications interfaces, said first module being constructed to produce a set of output signals the same as that of said second module; a printer interface; and a printer connected from said printer interface, said printer interface including an electrical socket, said first and second modules having first and second plugs, each of said plugs being constructed to mate with the self-same said socket, said first and second modules being alternately connectible with said printer interface to convert said first and second codes, respectively, and alternately to the same set of signals to operate said printer.
Claim 9
Dependent Claim
25 words
The invention as defined in claim 6, wherein said first code is the conventional RS232C code and said second code is the conventional Centronics code.
Claim 10
Dependent Claim
25 words
The invention as defined in claim 6, wherein said first code is the conventional RS232C code and said second code is the conventional IEEE code.
Claim 11
Dependent Claim
25 words
The invention as defined in claim 6, wherein said first code is the conventional Centronics code and said second code is the conventional IEEE code.
