The 64C2 is a single slot, 6U VME multi-function I/O and serial communications card. The “mother board” contains 6 independent module slots, each of which can be populated with a function specific module. The 64C2 VME I/O Board can be controlled via Ethernet, as well as by the VME databus. This unique design eliminates the need for multiple specialized, single function cards by providing a single board solution for a broad assortment of signal interface and serial communication modules. This increases packaging density, saves enclosure slots, reduces power consumption and adds continuous background BIT testing
