MVME410

The DPP is an I/O Channel-compatible dual printer interface module. ‘Ihis module confonns to the single-wide VME board fonn factor and connects to the I/O Channel with a 64-pin DIN standard connector. ‘Ihe DPP is used to expand the resources of an I/O Channel master to include two printer interfaces, one printer interface and a general-purpose 16-bit parallel data I/O port, or two general-purpose 16-bit parallel data I/O ports.
‘1\-.o PIA’s (with buffers on their peripheral sides) are employed to implement the two parallel data ports. In addition to having an I/O Channel interface, each of the PIA’s is capable of driving up to two of the I/O Channel interrupt lines.
A front panel FAIL LED indicator is provided to indicate a module malfunction. The user must provide a connector-compatible I/O Channel backplane or ribbon cable for DPP connection to the I/O Channel master. Refer to the I/O Channel Specification Manual, ~torola publication number M68RIOCS, for interfacing and backplane information. ‘Ihe user must also provide compatible cables for DPP connection (via front panel connectors) to peripheral devices.
1.5 RELATED DOCUMENTATION
The Input/Oltput Channel Specification Manual, M68RIOCS, is applicable to the DPP.
