Functional Features: High‑performance embedded computing for VME‑bus master control system. Intelligent VME bridge realizes flexible data interaction between local peripheral and backplane bus. Multiple configurable serial ports and Gigabit Ethernet for multi‑device communication access. Built‑in watchdog timer supports NMI interrupt or VME SYSFAIL signal output on timeout. Complete hardware self‑diagnosis covers power supply, memory, bus and peripheral channels.

Application Scenarios: VME‑based industrial control rack main controller. Real‑time hardware‑in‑loop simulation test platform. Data processing and gateway unit for power substation automation system. High‑speed process control equipment in petrochemical industry.

Structural Characteristics: Standard 6U single‑slot plug‑in VME module structure. Front‑panel LED status indicators for power, fault, network and system activity. Front‑panel external interfaces including Ethernet, serial port, VGA, USB, PS/2 keyboard‑mouse.

Working Principle: Backplane VME‑bus signals access module via P1/P2 golden‑finger connectors. On‑board Pentium‑M processor executes system computing, task scheduling and data processing.

Installation Requirements: Install module into designated slot of standard 6U dual‑P1/P2 VME chassis. Set as slot 1 when used as VME system controller. Cabinet grounding shall strictly follow system design specification.
