Various data systems as represented by several processing units have permanent multiple switch connections to a common set of peripheral devices. A coordinating actuator means is provided for each set of switches connecting together a peripheral device and a CPU so that the coordinating actuator means for all possible combinations may be conceived as being arranged in a matrix consisting of columns and rows, along one axis of which are arranged the CPU's and along the other axis of which are arranged the peripheral devices. The present invention provides a panel means having indicator elements arranged in a matrix pattern of columns and rows to simulate the switching matrix so that each column repesents a particular device of one kind, CPU or peripheral device, and each row represents a particular device of the other kind. Associated with each row and column is a manually actuated switch element and between the switch elements and coordinating actuator means are gate means for each of the coordinating actuator means, with two inputs, one from a column and one from a row. Simultaneous signals at the gate means permit activation of the coordinating actuator means to connect the represented devices when there is simultaneous actuation of the manually actuated switch elements in their respective row and column. The gating feature permits either an output signal to directly activate the coordinating actuator means or a coded output designed to actuate a specific remote coordinating actuator means. Such coding may employ 'Touch-Tone,' ASCII, or other code and the code may be transmitted on the same channel used for data transmission in the data system or on a separate channel.
