V120
VXI Fiber Optic FOXI Slot-0 Controller Module

The KineticSystems FOXI interface provides a fiber optic connection between a PCI-based host computer or workstation and one or more VXI mainframes to provide a high-throughput, deterministic data acquisition and control system.

The fiber optic based FOXI system supports distances between nodes up to 2 km (6,560 ft) with an I/O throughput to 10 MB/s. A complete FOXI system includes a V124 fiber optic FOXI host adapter, up to 126 V120 VXI fiber optic slot-0 controllers and a fiber optic cabling highway.

The V120 is a single-width, C-size, VXIbus controller that interfaces the FOXI highway to a VXI mainframe. It is a slave device on the highway and receives its commands from the host adapter. This module meets all the requirements of a VXIbus Slot-0 controller, including a MODID register for geographic addressing, a "CLK10" 10 MHz source, TTL/ECL trigger functions, and VXI interrupt handling. Interrupts generated in the VXI chassis are acknowledged by the V120, causing a demand message to be transmitted over the highway to notify the host.

The V120 communicates with the VXIbus using A32, A24, or A16 addressing modes as well as D32, D16, or D08 (EO) data transfers. All access via VXIbus is performed using register-based commands. This module includes a 16 MHz clock driver, a data transfer bus priority arbiter, and an interrupt handler.
