Abstract:

Digital interface circuitry links a number of solenoid-driven, multiple-port, single-transducer pressure-scanning devices to a digital data acquisition microprocessor system having a random access interface which directs operation of the microprocessor CPU. Pulses from the CPU are utilized by the digital interface to step the scanning solenoid and command the CPU to scan the current inputs from the pressure devices. The digital interface receives a digital signal from a binary encoder when the pressure scanning system has reached the last active pressure port and then returns the scanning system to home position and inputs the next user command to the CPU.
