Xycom XVME-400

The Xycom XVME‑400 is a single-height, single-width 6U serial I/O module compliant with the VMEbus (IEEE 1014) standard. It features four RS‑232C serial ports, designed to enable high-speed serial communication in VME systems. Equipped with two Zilog Z85C30 (or compatible) serial communication controllers, the module supports asynchronous, synchronous, and bit-oriented protocols. It can directly connect to external devices via the JK1 and JK2 front-panel interfaces or interact with the host through the VMEbus P1 connector.

Key Specifications

• Dimensions: Single-height 3.9 in × 6.3 in (approximately 99 mm × 160 mm), conforming to 6U VME standards.
• Power Supply: +5 V typical 1.1 A (max 1.3 A), +12 V typical 100 mA (max 110 mA).
• Operating Temperature: 0 °C ~ 65 °C (operational), -40 °C ~ 85 °C (non-operational).
• Interfaces: 4 RS‑232C ports (each providing RTS, CTS, DCD, DTR control signals); front-panel JK1 and JK2 are 25-pin D-sub connectors.
• Data Rate: Up to 57.6 KB/s in internal/external asynchronous mode; up to 500 KB/s in internal/external synchronous mode.
• Compatibility: Complies with VMEbus A16:D08(O) DTB slave specifications, supporting interrupt vector D08(O) (dynamic) and I(1)-I(7) interrupt sources.

Product Features

• Plug-and-Play: Single-height, single-width design occupies only one VME slot, enabling easy installation.
• Multi-protocol Support: Implements RS‑232, RS‑422/485 (via different models), and synchronous/bit-oriented protocols through the Z85C30 controller, meeting diverse industrial field requirements.
• High Reliability: Adheres to VMEbus electrical and mechanical standards, offering complete RTS/CTS/DCD/DTR control for convenient hardware flow control and modem functionality.
• Wide Temperature Range: Suitable for harsh industrial environments (0 °C ~ 65 °C) with moisture and static resistance.
• Bidirectional Interrupts: Supports VME interrupts to report serial port events (e.g., reception completion, errors) to the host, enhancing real-time performance.

Structure and Composition

• Front Panel: Two sets of 25-pin D-sub connectors (JK1, JK2), each providing 4 RS‑232C ports; features a slot latch handle for easy insertion and removal.
• Main Circuit Board: Dual Z85C30 SCC chips, power regulation module, VMEbus interface (96-pin P1), and power filtering/regulation circuitry.
• Backplane Connection: Enables full interaction of address, data, and control signals via the P1 96-pin VMEbus connector.
• Heat Dissipation and Protection: Metal housing with heat sinks meets 6U chassis cooling requirements; the enclosure provides dust and moisture sealing.

Typical Application Areas

• Industrial Automation: Serial data acquisition and command issuance for PLCs, CNC machine tools, and robotic control systems.
• Process Control: Communication between sensors, actuators (e.g., valves, inverters) and upper-level computers via RS‑232.
• Test and Measurement: High-speed serial interfaces for instruments and data recorders.
• Aerospace and Defense: Reliable serial links in VME-based embedded computing platforms.
• Laboratory Equipment: External communication for scientific instruments such as spectrometers and oscilloscopes.

Installation and Maintenance Guidelines

• Slot Preparation: Ensure the target VME slot is unoccupied, with clean guide rails free of debris.
• Alignment and Insertion: Insert the module with the front-panel handle facing down, gently pushing until the plastic rails on the front panel secure the module’s sides.
• Peripheral Connection: Use standard 25-pin D-sub cables to connect RS‑232C ports to external devices, ensuring correct cross-wiring (TX↔RX) and control signal alignment.
• Power Check: Verify stable VME chassis power supply, with module 5V and 12V currents within specified ranges; check for peripheral short circuits if overcurrent alarms occur.
• Interrupt Configuration: Enable corresponding I-vector interrupts in the VME host BIOS/drivers to ensure serial port events trigger interrupts.
• Regular Maintenance: Every 12 months, inspect slot latch tightness, heat sink dust accumulation, and connector pin oxidation; clean with lint-free cloth and isopropyl alcohol if necessary.
