Analog I/O card for VME
Pittsburgh, Pa. —VMAC is a 3U VME carrier board that accepts from one to eight plug-in analog I/O modules. An on-board microcontroller senses which slots contain I/O modules at power up. Then it initializes modules and performs setup. All initialized modules are individually interrogated with last valid and buffered data transferred to on-board SRAM.
