• Optional heat sinks or fans are available for harsher operating environments.

Dimensions

• Standard 6U VME form factor (approximately 233 mm × 100 mm × 166 mm), complying with VME backplane mechanical specifications.

Reliability

• Meets the anti-vibration and shock resistance requirements of IEC 60730-1 and MIL-STD-810G.
• Suitable for field environments with high noise and strong electromagnetic interference.

Product Features

• Modular Plug-and-Play: No welding or additional wiring required. Simply insert into the VME backplane to operate, reducing system integration time.
• High Reliability: Industrial-grade temperature range, anti-vibration design, and redundant power supply options ensure long-term continuous operation.
• Rich I/O Expansion: Multiple interfaces including Ethernet, serial ports, and USB meet the needs of on-site data collection, remote monitoring, and device linkage.
• Flexible Firmware Storage: Built-in programmable EPROM/Flash supports on-site upgrades and custom boot images.
• Multi-OS Compatibility: Compatible with real-time and general-purpose operating systems such as VxWorks, QNX, and Linux, adapting to different software ecosystems.

Structure and Composition

• CPU Core Board: Integrates the processor, main clock, and system bus bridge chip.
• Storage Subboard: Includes SRAM and programmable Flash/EPROM, providing runtime memory and firmware storage.
• I/O Expansion Slots: Reserved standard VME-64x slots for inserting additional communication, analog, or digital I/O modules.
• Power Management Unit: Implements multi-voltage input conversion, overvoltage/overcurrent protection, and power monitoring.
• Heat Dissipation Device: Heat sink or optional fan ensures thermal management under high loads.
• Connectors: Backplane pins, front-panel ports (Ethernet, serial, USB), and power terminals.

Typical Application Areas

• Industrial Automation Control: Core computing unit for PLCs, SCADA systems, and motion control systems.
• Military and Aerospace: High-reliability platforms for flight control, navigation, and data collection.
• Transportation: Train signaling, rail transit monitoring, and dispatching systems.
• Energy and Power: Power plant monitoring, distribution network automation, and wind/solar inverter control.
• Research and Experimental Platforms: Laboratory instruments requiring high-speed data collection via VMEbus.

Installation and Maintenance Guidelines

Installation

1. Align the module with the VME backplane slot and press gently until the latch locks into place.
2. Verify that the power supply voltage range meets the module specifications and connect the power terminals.
3. Connect the required front-panel I/O (Ethernet, serial, USB) and any expansion cards.

Debugging

1. After power-on, check the backplane indicator lights to confirm normal operation of the power supply, bus, and I/O.
2. Download firmware via JTAG or serial port and verify the boot image.
3. Use VMEbus diagnostic tools (e.g., VME-Scope) to check for bus communication errors.

Daily Maintenance

1. Regularly inspect heat sinks or fans for dust accumulation to maintain good heat dissipation.
2. Monitor the input voltage and current of the power supply to prevent hardware damage from overvoltage/overcurrent.
3. Perform moisture and corrosion protection treatments based on the operating environment (e.g., high humidity) and replace sealing gaskets if necessary.
4. Firmware upgrades are recommended during system shutdown or in safe mode to avoid runtime interruptions.

Troubleshooting

• No Power Supply: Check power cables, fuses, and backplane power distribution.
• Bus Errors: Use VMEbus monitoring software to locate error frames or timing conflicts.
• I/O Abnormalities: Replace the corresponding front-panel cables or expansion cards and verify port configurations.
