VME 428 3U VME bus Network Interface Card

The Micro Link VME428 provides an efficient way to network VMEbus systems together, and to connect VMEbus systems to other computers. Micro-Link offers the VME428 packaged with appropriate software for the VME200 family of single board computers. These packages support the most widespread Ethernet protocols for data transfer, remote access, distributed data storage, and network wide task-to-task synchronization.

The VME428 includes the Ethernet controller, interfaces for both Thick and Thin Ethernet media, buffer memory, VMEbus interface, Control and Status Register, VMEbus Interrupter, and EPROM storage.

The VME428 incorporates the LANCE (Local Area Network Controller for Ethernet) controller with the serial interface adapter. The VME428 also includes both an isolated interface to the Thick Ethernet tap MAU (Media Adapter Unit) and a Thin Ethernet transceiver and connector.

Up to 1 MByte of on-board buffer RAM memory is available to the LANCE and also to the VMEbus.

The VME428 includes three diagnostic LED indicators which display the operating status of the card.

Micro-Link offers three options from Microware Systems Corporation for linking multiple OS-9 systems as well as linking OS-9 systems to UNIX, VAX and other operating system environments. Micro-Link provides the low-level hardware-dependent drivers necessary to operate these packages with the VME428 controller.

  1. Microware's OS-9/ISP (Internet Support Package) supports network communications between OS-9 and other systems using the DARPA Transmission Control Protocol/Internet Protocol (TCP/IP). OS-9/ISP is modular and features a Socket File Manager (for BSD4.3 UNIX socket-style interface) and a complete Internet C library. The package also includes gateway and IP packet routing, and FTP and Telnet protocols for file transfer and remote login. A device-dependent interface layer allows OS-9/ISP to be used in almost any network transport hardware including communications in multiple processor systems.
  2. OS-9/N.F.S. (Network File System) provides an integrated and seamless software environment for distributed application development and implementation. OS-9/N.F.S. allows software developers to write an application on a single host, compile the code and store the application on the host's disk. Then, the remote systems, regardless of operating system or hardware platform, can mount the host's file system via the standard OS-9 I/O interface and transparently execute the application at the remote location.
  3. OS-9/NFM (Network File Manager) is a hardware-independent link between multiple OS-9 systems. OS-9/NFM fits directly into OS-9's unified I/O system and is compatible with all popular networking hardware including Ethernet on the VME428 and others. OS-9/NFM can also be used for multiple processor support allowing communication between CPU's sharing a common data bus.
