Product Description

The VCB 8004 is a 6U (double height) VME board constructed to the VME64x standard, with EMC front panel, injector/ejector handles, guide pin and slot keying, static discharge protection, hot swap capability, blue power up LED, geographical or jumper selected addressing, 5-row P1 and P2 connectors and 5-row P0 connector. The module features hot-swap capability with auto power up and host interaction. An on-board FPGA allows full mapping of the IP board memory, I/O and ID spaces. The VME interface supports short I/O access A16: D16:D08 (EO), standard I/O access A24:D16:D08 (EO) and extended memory access A32: D64: D32: D16. The module also has the ability to carry out MBLT A32 D64 and BLT A32:D32:D16 data transfers on IP memory space.

Four Industry Pack sites are available and can accept 4 single-size Industry Packs. The board has the capability to multiple-address the memory of IP sites and read/write data to them simultaneously using a data width of 32 or 64 bits. The carrier board supports 8MHz and 32MHz IP interfaces. One of VMEbus interrupt lines IRQ1 to IRQ7 can be selected and enabled by writing to an on-board register. The Industry Pack interrupt lines IntReq0* and IntReq1* from each of the four sites can be enabled on an individual basis and mapped to the selected VME IRQ line.

Four front panel mounted LED’s flash to visually confirm completed IP access cycles to individual slots. There is a TTL ‘Inhibit’ input on the front panel that allows connection to any or all of the IP card Strobe* lines through jumpers. The signal is routed through this pin on the IP logic connector to allow overall control to be applied to IP boards in data acquisition systems. The ‘GO’ output can be connected to the ‘Inhibit’ input through a jumper to synchronise timing between carrier boards.

The carrier board has some thickened I/O tracks to allow the IP boards to be powered externally to give full isolation. All I/O is via the VME backplane P0 and P2 connectors as specified in the VME64 extensions specification. The signals connect to the industry pack sites according to the VME64x Greenspring pinout for IP module carriers. Hytec has a number of rear-mounted transition cards with high-density 50-way [SCSI2] connectors, which can cater for all 200 IP I/O signals and provide any necessary signal conditioning.
