Advanet Advme1522a

Introduction

The Advme1522a is a shared memory board for sharing data between distributed systems. This is achieved via a fiber communication system which allows distances of upto 1km. Used by connecting multiple Advme1522A or Adpci1523 (shared memory board for PCI bus) boards in a loop using optical fiber. Only the resistor for default settings and shared memory area can be accessed from software.This product is ideal for linking remote systems and linking VME bus systems with PCI bus systems.

The board features a built-in communication function with a bit rate of 250Mbit/s and data communication speed of 4MBytes/s. Mapping of shared memory area can be modified and memory size can be expanded. Board also has built-in adjacent node failure and cable break detection function. Added CRC and data backup ensures high reliability of communications. Interrupt command is used to control the timing of data updates between nodes.

Device drivers and sample programs for VxWorks available (option).
