RS232 interface for A-D converter ICL7106
Many of today's electronic test instruments feature an RS232 interface for data exchange with a PC. Such an interface brings remote logging, statistic processing and presenting of sampled data within easy reach, all with the aid of a PC. The circuit described here adds an RS232 interface to older test equipment based on the familiar ICL7106 ADC and LCD driver.
