The Mod. V2718 is a 1-unit wide 6U VME master module, which can be controlled by a standard PC equipped with the PCI controller card CAEN Mod. A2818. The connection between the V2718 and the A2818 takes place through an optical fiber cable (AY2705, AY2720, AI2705, AI2720). Multi crate sessions can be easily performed, since up to eight daisy chained (via optical fiber cables) V2718 can be controlled by one A2818, thus building a CONet (Chainable Optical Network). The V2718 can perform all the cycles foreseen by the VME64 (except those intended for 3U boards). The board can operate as VME System Controller (normally when plugged in the slot 1) acting as Bus Arbiter in Multimaster systems. The VME bus activity can be monitored in detail, both locally (through a LED display) and remotely. The front panel includes also 5 TTL/ NIM programmable outputs on LEMO 00 connectors (default assignment is: DS0/1, AS, DTACK, BERR and LOCATION MONITOR) and two programmable TTL/NIM inputs (on LEMO 00 connectors). The I/Os can be programmed in order to implement functions like Timer, Counter, Pulse generator, I/O register, etc. The LED display and the TTL/NIM I/Os are not available on Mod. V2718LC version. The sustained data transfer rate is up to 70 MByte/s. Thanks to the 128KB memory buffer, the activity on the VME bus is not slowed down by the transfer rate on the CONet when several V2718s share the same network. The Module is provided with drivers which support the use with the most common PC platforms (Windows 98/2000/XP, Linux, SGI Altix); libraries and useful example programsin C/C++, VisualBasic and LabView are provided as well. Future firmware upgrade is possible via PCI.
