Product Function Description

VMIVME‑7750 is a single‑slot passively cooled 6U VME single‑board computer built on Intel Pentium‑III platform, designed for high‑reliability embedded industrial applications. It can serve as main system controller or secondary peripheral CPU inside multi‑processor VME rack.

The PCI‑VME transparent bridge supports A24/A32 addressing and high‑speed block data transmission between local processor and other VME bus modules. PMC expansion slot allows users to install various custom I/O sub‑boards to expand hardware functions. Rich front‑panel peripheral interfaces include dual Ethernet, serial ports, USB, PS/2 and SVGA video output, supporting mainstream embedded operating systems such as VxWorks, QNX, Linux and Windows embedded series. Built‑in programmable hardware watchdog and multi‑group independent timers improve system fault tolerance for long‑term field operation.

Product Details

Standard 6U Eurocard structure, directly plug‑in VME cabinet slot, passive heat dissipation without fan. Conformal coated circuit board adapts to dusty and humid industrial environment. This legacy SBC has been end‑of‑life by original manufacturer, mainly used for old‑equipment overhaul and spare‑part replacement. Strict electrostatic protection shall be adopted during installation, verify BIOS firmware and PMC module compatibility before commissioning.
