The 64D2 is a 6U VME multifunction communications and digital I/O board with local processing capability and VMEBus Master/Slave support. It is available in air cooled or conduction cooled configurations. The “mother board” contains 3 independent slots, each of which can be populated with a function specific module. Additionally, Slot 3 can be populated with a DSP processor. This unique design eliminates the need for specialized, single function boards required for system integration by providing a combination of communication and digital I/O functions on one single board, thus reducing board count and power dissipation. All I/O data written to or read from the board can be managed over the Ethernet port or via the VMEBus
