VMIC VMIVME-7698-345 Single Board Computer

Module Feature

VMIC VMIVME-7698-345 is a 6U single-slot VME64 single-board computer built around Socket 370 Intel Celeron processor with MMX technology. It features dual-ported DRAM accessible by both local CPU and VMEbus master, onboard AGP SVGA graphics controller, 10/100 fast Ethernet, dual 16550 serial ports, Ultra DMA storage controller and PS/2 keyboard/mouse interface. Flash BIOS supports firmware field upgrade. Rugged 6U VME form factor with shock and vibration resistance, designed for high-reliability embedded control, simulation, test and aerospace applications.

Working principle

The onboard Celeron processor executes application and real-time operating system code. Local memory is dual ported so VMEbus master devices can directly read/write shared memory area for inter-board data exchange. Onboard peripherals including Ethernet, serial ports and video controller are mapped into CPU address space. The VME64 bus interface implements master/slave function to communicate with other VME modules in the chassis. Flash memory stores system BIOS and boot firmware.

Onboard components

Intel Celeron Socket370 CPU, dual-ported SDRAM, AGP SVGA video chip, fast Ethernet controller, UART serial controllers, flash BIOS chip, VME64 J1/J2 bus transceivers, front panel I/O connectors, status LED array.

LED indicators

Front panel LEDs for power, CPU activity, Ethernet link/activity, VME bus access and fault warning.

Hardware self-diagnosis

Visual inspection of PCB, front panel and connectors; power-up POST self-test; memory read/write test; VMEbus register access test; Ethernet loopback test; serial port communication test; BIOS version verification.

Programming software

Supports VxWorks, Linux and Windows embedded OS; VMIC VME device driver suite, BIOS configuration utility, board diagnostic firmware.

Installation

Follow ESD safety procedure before handling. Power off VME chassis completely. Insert board into vacant 6U VME slot and tighten front panel ejector latches. Connect front panel Ethernet, serial, keyboard/mouse and video cables as required. Boot system and enter BIOS to configure memory and peripheral settings. Load OS and VME drivers, run board diagnostic before commissioning.
