Reduce costs by reducing operating crew size. Taking the operator out of the cab, allowing him to be where the action is, elimi-nates hand signals or second-hand radio voice communications and puts the operator in complete, real time control. Control is secure because biphase data transmission and Cyclic Redundancy Check codes prevent false motions and provides for controlled shutdown. Digital messages are checked for address, format, and content before any motion or function is activated. While in motion, check circuits continuously moni- tor the received message and the quality of the RF carrier...
