Description

V7768-322001 6U VME64x Single Board Computer (Core2 Duo)

Product Application

V7768-322001 is a ruggedized VME single-board computer for mission-critical embedded control systems, widely used in legacy steam/gas turbine control, power generation test systems, aerospace and industrial real-time data acquisition. It acts as the VME rack host controller, executes control algorithms, reads/writes VME I/O boards over VMEbus, communicates with HMI and upper DCS via dual Gigabit Ethernet. Supports VxWorks, Linux real-time operating systems.

Note: V7768-322001 is upgraded version compared with V7768-320001 A2, different processor and memory configuration, not fully pin-to-pin compatible in some firmware revisions.

Installation Guidelines

Power off VME chassis, insert V7768-322001 into designated 6U VME slot and secure front panel latches.
Install CompactFlash with real-time OS and application firmware.
Connect front panel Ethernet, serial or VGA cables as required.
Power on chassis, enter BIOS to set boot device and system parameters.
Boot real-time OS, load VME driver and scan all VMIVME I/O boards on backplane.
Configure network IP for dual Ethernet ports, test communication with HMI/DCS.
Perform VME bus read/write test with VMIVME I/O modules.
Validate hardware watchdog function before online commissioning.

Maintenance Instructions

Daily Maintenance Check board power and status LED; monitor system health and network status on HMI.

Periodic Maintenance (Every 6–12 months) Clean chassis filter and PCB dust. Check RTC battery status, replace battery when low. Backup OS image and application project. Inspect backplane connector pins.

Fault Maintenance

Cannot boot: Check CompactFlash integrity, VME power supply and BIOS configuration.
VME bus communication failure: Inspect backplane, VME address mapping and driver.
Network port failure: Check cable, link negotiation, or test second GbE port.
Do not modify BIOS or real-time control application without turbine control engineer approval.

Long-Term Operation Tips Keep chassis temperature within 0~55°C. Store spare V7768-322001 in dry environment. Keep full OS & application backup image.
