The Mod. V1718 is a 1-unit wide 6U VME master module which can be operated from the USB port of a standard PC; the board 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 via USB 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. V1718LC version. The V1718 – PC interface is USB 2.0 compliant; previous issues are also supported. USB data transfer takes place through the High Speed Bulk Transaction protocol; the sustained data rate on the USB is up to 30 MByte/s in BLT Read cycles. Thanks to the 128KB memory buffer, the activity on the VME bus is not slowed down by the transfer rate on the USB port. The Module is provided with drivers which support the use with the most common PC platforms (Windows 98/2000/XP, Linux); libraries and useful example programs in C/C++, Visual Basic and LabView are provided as well. Future firmware upgrade is possible via USB.
