The 64C2 is a single slot, 6U VME Multifunction I/O and Communications Board. 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. The 64RT2 Rear Transition card is available for outside interconnection.
