VMIC VMIVME-7698 Single Board Computer

Module Feature

VMIC VMIVME-7698 is a 6U single-slot VME64 single-board computer built around Socket 370 Intel Celeron processor. It integrates a PMC expansion mezzanine site, dual-ported SDRAM accessible by local CPU and VMEbus master, AGP SVGA graphics controller, 10/100 fast Ethernet, dual 16550 UART serial ports, Ultra DMA/33 IDE storage controller and PS/2 keyboard/mouse interface. Flash BIOS supports field firmware upgrade. Passive heatsink design with no moving fan. Ruggedized Eurocard construction with shock and vibration resistance, widely adopted for real-time simulation, aerospace test, industrial embedded control and data acquisition systems.

Working principle

The onboard Celeron processor executes real-time operating system and user application code. Dual port memory enables VMEbus master modules to directly read and 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 bridge implements master/slave functions to communicate with other VME modules inside the chassis. Flash memory stores system BIOS and boot firmware; watchdog timer provides automatic reset for system failure recovery.

Installation

Follow ESD safety procedure before handling. Fully power off VME chassis. Insert board into vacant 6U VME slot and engage front panel ejector latches. Connect front panel Ethernet, serial, video and PS/2 cables as required. Power on chassis, enter BIOS to configure memory, boot device and watchdog parameters. Install OS and VMIC VME drivers, run board diagnostic routine before commissioning.

Interface

VME J1/J2 backplane connector, PMC mezzanine site, 10/100 RJ45 Ethernet, 2 x RS232 serial port, SVGA video, PS/2 keyboard/mouse, IDE and floppy I/O via P2 connector.

Diagnostic

Board fails POST: faulty CPU/SDRAM, damaged edge connector, insufficient backplane power. VME communication abnormal: incorrect slot mapping, missing bus termination, damaged VME transceivers. Ethernet no link: defective cable, wrong duplex mode, PHY hardware failure. Watchdog malfunction: incorrect BIOS watchdog setting.
