VMEbus systems. This module is built to commu- nicate with Xycom’s XVME-65x VMEbus PC/AT processors. Power for the XVME-977 is provided by the P1 and P2 connectors. Signals are routed through P2. Figure 1-1 illustrates this in a block diagram of the XVME-977.
Installing into a VMEbus Card Cage The XVME-977 occupies only one double-high VMEbus slot, and fits into any standard 6U VMEbus card cage. Like all of Xycom’s modules, the XVME-977 is designed to comply with all electrical VMEbus backplane specifications. This module only draws current from the +5 volt power supply.
