Simple Parallel Interface Between An Optical Multichannel Analyzer And A Microprocessor, Stephen E. Bialkowski
Stephen E. Bialkowski
A simple circuit is given which will allow data transfer from a LSI‐11 DRV11 parallel interface unit to a PARC 1216 Optical Multichannel Detector Controller. The Circuit for OMA to LSI‐11 data transfer is slightly more complicated. Data buffering is used so that data transfer can occur without time‐out loss due to the dynamic memory refresh cycle of the LSI‐11. The circuit may be constructed and mounted within the PARC 1216 unit with only minor, noncritical, modifications to the controller unit. The unit is able to transmit data from the 1216 controller running at dwell times as short as 40 …
