Abstract

The figure depicts the signal flow through the system ele-~ ments of a computer interface module designed to auto~- matically transfer a large number of micrometer data readings into a digital computer for data processing. This automated data transfer replaces the prior art method of visually reading the data and then entering it into the computer via a teletype terminal or similar means. The principal functional blocks include a clock network 10, a control, timing and transmit switch 12, multiplexer 14 and an ASCII coded character transmitter 16. Two channel switches (not shown) are provided to control power on/off; transmit axis X or Y, transmitter speed ~lO or 30 characters/second) and momentary transmit. The clock network 10 provides timing and synchronization pulses for the entire system. Two pulse rates are selectable, one for 10 characters/sec (100 Baud) and one for 30 characters/sec (300 Baud) . The multiplexer 14 selects the sequence of 5 binary coded decimal digits from converter 18 and 20 which represent the data from the x-axis and y-~axis 5-digit dis- play1 respectively. A signal on lead 22 indicates that the
