VMIVME-DR11W-A VMEbus High-Performance DR11W Interface • Provides parallel DR11W-A and DRV11-WA-compatible interface from VMEbus to DEC, Concurrent/Masscomp, Prime, Sun Workstations, Data General, Harris Night Hawk, IBM PC/AT, Multibus, and VERSAbus • 32-bit data transfers • 32-bit addressing • Provides interface to high-resolution graphics terminals such as Raster Technologies, Megatek, and Chromatics • Byte and word swapping (selectable under software control) • Watchdog timers prevent transfer lockout on VMEbus and cables • Front panel fail LED • Supports off-line Built-in-Test plus single board loopback testing (with test cable) • Meets VMEbus spec. C.1 - compatible address pipelining • Fully programmable operation (includes selection of 16-/32-bit transfer, burst mode, etc.) • Fully programmable interrupt levels and vectors • Software compatible with VMIC’s DR11W and DR11W-485 boards with allowances for longwords and defined function 1-bit (direction) 3 • Two VMIVME-DR11W-As form VMEbus-to-VMEbus link Maximum Cable Length: 50 ft • UNIX system V.3 driver available POWER REQUIREMENTS SPECIFICATIONS 4.5 A (estimate) typical at +5 VDC As a Master: A24:A32:D8:D16:D32 PHYSICAL/ENVIRONMENTAL Bus request levels 0, 1, 2, or 3 (jumper-selectable) Temperature: 0 to 55 °C, operating As a Slave: A16:A24:D8:D16 -20 to 85 °C, storage Addressable on 256-byte boundaries in short I/O space Addressable in top 64 Kbyte or bottom 64 Kbyte of Relative Humidity Range: 20 to 80 percent, standard address space noncondensing Bus Grant Delay: 70 ns (see note) Cooling: Convection TRANSFER SPECIFICATIONS Dimensions: Double Eurocard 160 x 233.4 x 12.5 mm Maximum Transfer Rate: Fail LED: A Fail LED is provided which is illuminated at power up and extinguished under program control 1 Burst: 1.8 Mbyte/s (VME-to-VME) upon successful diagnostic execution 1.0 Mbyte/s (Q-Bus) TRADEMARKS 1 Single cycle: 1.1 Mbyte/s (VME-to-VME) The VMIC logo is a registered trademark of VMIC. 0.5 Mbyte/s (Q-Bus) Other registered trademarks are the property of their Maximum Block Size: 256 Kbyte minus 4 bytes respective owners. 2 Transfer Size: 8, 16, 32 bits Transfer Mode: Bidirectional half-duplex 3. If used with a non-VMIC DR11W product, the maximum Addressing Range: 32 bits cable length may be limited by that product. I/O CABLES (Not Included) Note — For optimum system performance, VMIC recommends that a different bus request level be used for each DR11W-A controller Connection Cables: Two 40-conductor flat-ribbon located on the same VMEbus chassis. Up to 19 DR11W-A cables (high quality shielded cables required) controllers may use the same request level; however, the total bus grant delay will significantly reduce the throughput of the controllers near the end of the daisy chain. 1.
