MOTOROLA MVME2434

Product Introduction

The Motorola MVME-707 is a specialized VMEbus communication interface module, engineered to integrate serial (RS-232/RS-422) and parallel (IEEE 1284) connectivity with basic digital I/O—filling the gap between single-interface communication modules (e.g., MVME333-2) and complex multi-protocol gateways. As a 3U VME form factor device, it is designed for industrial systems that require connectivity to both legacy serial devices (e.g., barcode scanners, legacy HMIs) and parallel peripheral equipment (e.g., industrial printers, data loggers), while retaining basic discrete control capabilities for auxiliary tasks.

A defining strength of the MVME-707 is its seamless integration with the Motorola VME ecosystem. When paired with a host SBC like the MVME5500, it leverages the VMEbus to receive configuration commands (e.g., serial baud rate, parallel transfer mode, digital I/O direction) and transmit multi-interface data—such as RS-422 sensor readings from remote equipment, parallel print data for production labels, and digital I/O states from safety interlocks. It draws stable power from modules like the FAB 0340-1049 (via VME backplane) or 01-W3324F (for auxiliary power), while its passive cooling design ensures compatibility with space-constrained VME chassis where airflow is limited.

Whether deployed in manufacturing production lines、laboratory data acquisition systems, or industrial inventory management setups, the MVME-707 enables versatile device connectivity. Its parallel port supports high-speed data transfer for peripheral devices, while serial ports retain compatibility with thousands of legacy industrial components—making it a critical component for legacy VME systems requiring both classic and parallel communication interfaces.

Core Advantages and Technical Highlights

Multi-Interface Integration for Diverse Device Connectivity

The MVME-707’s combination of 2x serial ports, 1x parallel port, and 4x digital I/O channels eliminates the need for separate serial modules and parallel interface cards—reducing VME chassis slot usage by up to 66%. For example, in a manufacturing production line, the module can: 1) use 1x RS-422 port to connect a remote barcode scanner (tracking product serial numbers 500 m away), 2) use 1x RS-232 port to link to a legacy HMI (for operator control), 3) use the parallel port to send production data to an industrial label printer (2 MB/s EPP mode), and 4) use 2x digital inputs to monitor printer paper status, 2x digital outputs to activate printer alarms. This integrated design simplifies wiring, reduces communication latency between devices, and lowers overall system cost compared to mixed single-interface modules.

High-Speed Parallel Port for Peripheral Data Transfer

The MVME-707’s IEEE 1284-compliant parallel port supports EPP mode with data rates up to 2 MB/s—far faster than serial ports (115.2 kbps max) and critical for applications requiring high-volume data transfer to peripheral devices. Unlike serial-based printers or data loggers, which struggle with large files (e.g., production reports, test data logs), the parallel port enables near-instantaneous transfer of 100 KB label templates to an industrial printer—reducing print wait time by 95% compared to RS-232. The SPP mode also ensures compatibility with older parallel devices (e.g., legacy data loggers) that do not support EPP, making the module a bridge between modern and classic parallel peripherals.

Serial Port Versatility for Legacy and Remote Devices

The MVME-707’s 2x serial ports support software-selectable RS-232/RS-422 modes—enabling connectivity to both short-range local devices (RS-232, 15 m) and long-range remote equipment (RS-422, 1200 m). For instance, in a water treatment plant, the module can use 1x RS-422 port to connect a pressure sensor 1 km away from the control cabinet (differential signaling minimizing noise), while using 1x RS-232 port to link to a local data logger (recording sensor data every second). The serial port surge protection (1 kV ESD) further safeguards against electrical interference from nearby pumps or valves, ensuring stable communication in harsh industrial environments—an advantage over unprotected parallel-only interface cards.

Compact Design and Low Power Consumption

The MVME-707’s 3U VME form factor and 0.6 A typical power draw (at +5 VDC) make it suitable for space- and power-constrained systems—such as portable test benches or auxiliary control cabinets with limited VME slots. For example, a laboratory data acquisition setup can use the MVME-707 to connect a RS-422-based environmental sensor (monitoring temperature/humidity), a parallel-port data logger (storing test results), and 4x digital I/O channels (controlling test chamber lights/fans)—all without consuming excessive chassis space or power. The passive cooling design also eliminates fan noise and failure risks, making it a good fit for quiet laboratory or office-adjacent industrial environments.

Typical Application Scenarios

Manufacturing Production Line Labeling

In a consumer goods manufacturing line, the MVME-707 (paired with MVME5500 SBC) manages product tracking and labeling: 1x RS-422 port connects a barcode scanner (50 m from the control cabinet, tracking product serial numbers), 1x RS-232 port links to a legacy HMI (for operators to input production batch numbers), 1x parallel port sends label data to an industrial printer (2 MB/s EPP mode, printing 100 labels per minute), 2x digital inputs monitor printer paper/low ink status, 2x digital outputs activate alarm lights for supply refills. The module’s parallel port speed ensures labels print in sync with product movement, while RS-422 long-distance capability eliminates the need for a scanner near the control cabinet—optimizing production line layout.

Laboratory Environmental Data Logging

In an environmental science laboratory, the MVME-707 (paired with MVME172-263/260 SBC) automates data collection: 1x RS-422 port connects a remote weather station (1 km from the lab, transmitting temperature, humidity, wind speed data), 1x RS-232 port links to a local pH meter (for water sample testing), 1x parallel port sends daily data logs to a high-speed printer (generating hard copies for research records), 2x digital inputs monitor printer power/paper status, 2x digital outputs control a test chamber fan (activating when temperature exceeds 30°C). The module’s low power consumption avoids overloading the lab’s portable power supply, while passive cooling ensures no fan noise disrupts sensitive experiments—an improvement over power-hungry external parallel cards.

Industrial Inventory Management

In a warehouse inventory management system, the MVME-707 (paired with MVME2434 SBC) coordinates stock tracking: 1x RS-422 port connects a handheld barcode scanner (used by workers to scan pallet labels 200 m from the control cabinet), 1x RS-232 port links to a legacy inventory HMI (displaying stock levels), 1x parallel port sends inventory reports to a laser printer (generating weekly stock summaries), 2x digital inputs monitor printer jam/error status, 2x digital outputs activate warehouse alarm bells (alerting staff to low stock). The module’s RS-422 multi-drop capability (up to 32 nodes) allows adding more scanners later, while parallel port speed ensures reports print before the next inventory cycle—critical for timely stock replenishment.

Installation, Commissioning and Maintenance Instructions

Installation Preparation

Before installing MVME-707, power off the VME chassis and disconnect the FAB 0340-1049 and 01-W3324F power supplies to prevent electrical shock. Verify the chassis has an available 3U VME slot and that the VME backplane supports 16-bit slave modules. Use an anti-static wristband and mat to protect the module’s serial/parallel components from ESD damage. Gather tools: Phillips-head screwdriver (for chassis mounting), twisted-pair cables (RS-232/RS-422, 22–18 AWG), IEEE 1284 parallel cable (for peripheral connection), torque wrench (0.5–0.8 N·m for terminals), and a multimeter (to test signal levels). Avoid installing near high-EMI equipment (e.g., variable-frequency drives) or heat sources (e.g., power supplies) to prevent signal interference or thermal damage.

Commissioning and Maintenance

For commissioning, insert the MVME-707 into the VME slot and secure it. Wire serial devices (RS-232: TX/RX/GND; RS-422: A/B/GND) and connect the parallel port to peripheral equipment (e.g., printer) via an IEEE 1284 cable. Connect digital I/O devices to the terminals, matching TTL/CMOS voltage levels. Power on the FAB 0340-1049 and 01-W3324F, then check the module’s LEDs: green “POWER” confirms voltage; serial “TX/RX” (blinking) indicates data transmission; parallel “DATA READY” (solid green) confirms peripheral connection; digital I/O “HIGH” (green)/“ACTIVE” (red) confirms state. Use the MVME5500’s configuration software to set serial parameters (baud rate, parity) and parallel transfer mode (SPP/EPP). Test communication: send serial test data to a remote sensor, transmit a test file to the parallel printer, and toggle digital outputs to verify alarm activation.

For maintenance: Inspect serial/parallel wiring monthly—tighten loose terminals, replace damaged cables (especially parallel cables with bent pins), and clean parallel port connectors with lint-free wipes (use isopropyl alcohol for dirt). Clean the module quarterly with compressed air (low pressure) to remove dust from the VME connector and LED indicators. Test serial port surge protection semi-annually using an ESD simulator (ensure 1 kV protection is active). If the parallel port fails, check for bent pins or incompatible peripheral settings; if digital I/O malfunctions, isolate the issue with a bench power supply. When upgrading, replicate the module’s interface configurations to avoid disrupting peripheral communication—use EEPROM backup to transfer settings to a new unit.
