Board Function: This 64-bit optically coupled, digital input board, was designed and optimized specifically for the VME. Featuring high isolation, the VMIVME-1150 provides a flexible, low-cost 8-byte digital input port with high noise immunity. The Functional Block Diagram is shown in Figure 1.
Compatibility: The VMIVME-1150 is a standard, double height printed circuit board that is electrically and mechanically compatible with the VME.
Input Organization: Eight input ports, each eight bits wide. The ports are arranged as eight contiguous 8-bit, read-only registers.
Addressing Scheme: Each 8-bit port, individually addressable on 8- or 16-bit boundaries anywhere within the short supervisory or short nonprivileged I/O space.
Board Address: The board address is selected by onboard DIP switches. Operation is supported in any available slot on the VME backplane, except slot 1.
