System module VXI Ethernet Controller

System module VXI Ethernet Controller
Item article:

The ETHERNET CONTROLLER module is intended for use as part of the VXI chassis as a system controller for slot 0 of the VXI trunk.


  • personal computer, an ETHERNET switch, or an ETHERNET hub to the VXI chassis via an ETHERNET interface;
  • a personal computer or USB hub to the VXI chassis via a USB 2.0 interface.


  • implementation of the VXI chassis slot 0 controller function in accordance WITH iec821 VMEbus Standart, Revision VMEbus Specification C. 1 and IEEE STD 1155-1992 Rev. 1.4.;
  • implementation of the VXI trunk subscriber (performer) function. The module has a logical address of 0 on the VXI bus.

The module operates under the INFORMTEST VISA library, which complies with the VXI Plug&Play specification.

Technical characteristics of the VXI module interface
The VXI interface of the module provides:
  • module device type - VXI register-based module;
  • full function of the Slot-0 VXI system controller;
  • Support for VXIbus rev. 1.4;
  • providing the dynamic configuration mode of the VXI modules of the chassis tools;
  • shaper system frequency and system reset VXI chassis;
  • VXI trunk arbiter function of PRI priority type;
  • VXI trunk interrogator function of ROR type (on-demand release trunk)
  • VXI trunk bus timer (WTO) function;
  • VXI trunk interrupt handler function of priority type;
  • Supported address space A16, A24, A32;
  • DATA TRANSFER DO8, D16, D16 BLT, D32, D32 BLT;
  • signal generator TTL TRG to any given line VXIbus TTL Trigger 0-7;
  • the ability to relay TTL TRG signals (reception / transmission) via an SMB connector to other chassis;
  • synchronization of several VXI crates from one 10 MHz clock frequency through the SMB type connector on the front panel of the module
Technical Specifications of the ETHERNET Module Interface
