Remote data controller for a communication system
First Claim
1. In a communications system including communications equipment having operator selectable functions and providing status signals representative of the operation condition of features of the communication equipment and means for controlling the communications equipment, the improvement in said controlling means comprising:
- control modules each including means for receiving indicia data representative of the operational condition of the features of the communications equipment and providing indicia representative thereof, and means for generating data for controlling the functions selected on the communications equipment;
at least two control panel means each coupled to a predetermined plurality of said control modules for communicating digitally with each of said plurality, each of said control panel means including a panel selector having a predetermined address, and a module selector having a predetermined address for selecting one of the control modules associated with a control panel means;
data interface circuit means coupled between the communications equipment and each of said control panel means for communicating digitally with each of the control panel means, said data interface circuit means including a microprocessor means for selecting one of said panel means and one of its associated control modules via addressing the corresponding panel selector and module selector, writing indicia data representative of said status signal to the selected control module via the selected control panel means, and for reading said control data generated by said generating means as coupled by said control panel means; and
means for selectively inverting the most significant bit in a binary number utilized to address said predetermined address of the panel selector after the generation of said binary number thereby defining a first range of addresses corresponding to the most significant bit not being inverted and a second range of addresses when the most significant bit is inverted.

Abstract
The communications system may include wireless two-way communications equipment having selectable functions and various operational features. Control modules each include mechanisms for providing indicia representative of the status of the features of the communications equipment and mechanisms for generating data for controlling the functions to be selected on the communications equipment. A group of the control modules are coupled to a panel module which selectively communicates with each of the control modules in the group. An interface circuit is coupled to a plurality of the panel modules for selectively communicating with each; the interface circuit includes a microprocessor for writing indicia data to each of the selected control modules via the selected panel module and reads the control data generated by the control modules. The periodic scanning and reading of information is utilized to ascertain changes in the data.
