VMIC VMIVME-7805 Single Board Computer

Module Feature

VMIC VMIVME-7805 is a single-slot 6U VMEbus single board computer powered by Intel Pentium 4-M mobile processor with Intel 852GM chipset, supporting up to 2.2 GHz CPU speed. It carries one PMC mezzanine expansion site for adding reflective memory or custom I/O modules. Equipped with dual Ethernet controllers: 1 gigabit Ethernet and one 10/100 fast Ethernet. Integrated graphics controller with DVI-I output supporting resolution up to 1600×1200. Onboard 2 × 16550 compatible serial COM ports, USB2.0 port, PS/2 keyboard/mouse interface, real-time clock and programmable hardware watchdog timer. Supports CompactFlash and IDE storage via VME P2 connector, and remote network boot function. Passive heat sink cooling design, rugged Eurocard construction, suitable for real-time simulation, industrial process control, test measurement and aerospace embedded systems.

Working principle

The Pentium 4-M processor executes embedded operating system and user application code. The PCI-to-VME bridge implements VMEbus master and slave functions for data exchange with other VME modules in the chassis. The PMC slot extends board function via mezzanine cards. Dual Ethernet controllers handle network communication, and integrated GPU drives DVI display. Flash BIOS supports firmware upgrade and boot configuration; watchdog timer automatically resets the board on software crash to improve system reliability.

Installation

Follow ESD safety procedure before handling. Fully power off VME chassis. Insert VMIVME-7805 into empty 6U VME slot and lock front panel ejector latches. Connect front panel DVI, Ethernet, serial, USB and PS/2 peripherals. Enter BIOS to configure boot device, watchdog and network boot options. Install OS and VMIC VME drivers, run full board diagnostic before commissioning.

Interface

VME J1/J2 backplane connector, PMC mezzanine site, DVI-I video, 10/100 RJ45 Ethernet, Gigabit RJ45 Ethernet, dual RS232 serial ports, USB2.0, PS/2 keyboard/mouse, IDE/CompactFlash via P2 rear I/O.

Diagnostic

Board fails POST: faulty SODIMM memory, defective CPU chip, insufficient backplane power. VME communication timeout: poor backplane contact, bus termination missing, PCI-VME bridge hardware fault. Ethernet no link: bad network cable, PHY chip damage, incorrect duplex configuration. Watchdog fails to trigger: wrong BIOS watchdog parameter setup.
