Abstract

In a processor system which includes a plurality of input devices connected to and controlled by an intelligent controller, a single control unit may support several interface protocols. Typically, the interfaces are mounted in the controller and may utilize inputs from associated modems. The cable connecting the input device to the controller will vary as a function of the protocol to be supported. Where the adapter is designed to support two or more interface protocols, it is designed to run in either mode under control of the cable attached to the interface.

Connection Device Identification

In a processor system which includes a plurality of input devices connected to and controlled by an intelligent controller, a single control unit may support several interface protocols. Typically, the interfaces are mounted in the controller and may utilize inputs from associated modems. The cable connecting the input device to the controller will vary as a function of the protocol to be supported. Where the adapter is designed to support two or more interface protocols, it is designed to run in either mode under control of the cable attached to the interface.

To provide this operation, the cable will utilize two extra conductors, which, when connected into the connector socket, will generate a two bit code to designate the prescribed mode for operation, at least one of the two bits being active. When the code is interpreted by the controller, hardware and software of the adapter will run in the specified mode. This eliminates the inconvenience of conversation between the device and controller to ascertain the desired mode of operation and cable connection. In addition, the two bit code will also indicate whether the cable between the interface and adapter is properly connected.
