Abstract: A digital information transmission system includes a control unit for transmitting digital words each including an address, message, and an error detecting code derived from the address and messsage to a plurality of uniquely addressable peripheral units over a common bus. Each peripheral unit includes a register which stores its address and when a digital word is received by a peripheral unit the address stored in its register is compared with the transmitted address and the transmitted error detecting code is compared with an error detection code generated from the received message and the stored digital address. When both the transmitted and the stored addresses match and the transmitted and the generated error detecting codes match, the utilization portion of the peripheral unit is enabled to respond to the transmitted message.
