ABSTRACT:
A data processing system which includes a host processor and a plurality of remote processing devices which are coupled to a common communication channel. The system also includes a look-up table storing the sets of instructions for a plurality of communication protocols for use with the remote processing device and a controller associated with one of the remote processing devices. A selectively actuated switch member located in the controller provides an address for the controller. During a power-up operation, the controller address is transmitted to the host processor for use in addressing the look-up table to obtain the communication protocol for the controller. This information is then loaded into the controller for controlling the transfer of data between the host processor and the remote processing device.
