Description
GE DS3800HMACIHIG Media Access Unit
Product Overview
The GE DS3800HMACIHIG is a high-performance Media Access Unit (MAU) designed for GE’s Mark IV Speedtronic turbine control system, serving as the critical interface for network communication and data transmission in industrial gas and steam turbine applications. As part of the DS3800HMAC series, this module integrates seamlessly with Mark IV I/O boards, microprocessor controllers, and HMIs to enable real-time data exchange, collision detection, and protocol conversion in mission-critical environments .
Engineered with dual coaxial connectors and triple modular redundancy (TMR) architecture, the GE DS3800HMACIHIG supports legacy Ethernet standards like 10Base5 (ThickNet) and 10Base2 (ThinNet), ensuring compatibility with aging infrastructure while delivering reliable performance in high-vibration, extreme-temperature settings (-30°C to +55°C) . Its dual-sided PCB houses over 40 integrated circuits, including AM26LS30 dual differential drivers and AM26LS33 quad differential receivers, which facilitate noise-resistant signal transmission across long cable distances . The module features three LED indicators (two red, one yellow) for real-time status monitoring of power, data transmission, and fault conditions, enhancing diagnostic visibility during operation .
While the Mark IV series is legacy technology, the GE DS3800HMACIHIG remains indispensable for maintaining industrial infrastructure in power plants, offshore platforms, and heavy manufacturing facilities. Its field-configurable jumpers allow users to adjust voltage thresholds, signal conditioning parameters, and communication protocols without hardware modifications, making it adaptable to diverse control scenarios .

Key Features and Advantages
Legacy Network Compatibility: The GE DS3800HMACIHIG supports 10Base5 and 10Base2 Ethernet standards, ensuring seamless integration with aging Mark IV systems while providing backward compatibility for legacy sensors and actuators . Its dual coaxial connectors enable long-distance signal transmission (up to 500 meters for 10Base5), critical for distributed control setups in power generation and oil refineries .
Rugged Industrial Design: Built with EMI shielding and surge protection, the module withstands extreme temperatures, voltage spikes, and mechanical vibrations. Its retention levers simplify maintenance by allowing quick removal and replacement without tools, reducing downtime during repairs .
Diagnostic Visibility: Three LED indicators provide real-time feedback on power status, data integrity, and fault conditions, enabling rapid troubleshooting. For example, a steady red LED alerts operators to communication errors, while yellow LEDs signal partial system alerts .
Field-Configurable Flexibility: Jumpers allow users to adjust voltage thresholds, signal conditioning parameters, and communication protocols, making the GE DS3800HMACIHIG adaptable to diverse control scenarios. This flexibility is ideal for retrofitting legacy systems with modern sensors or actuators .
Application Areas
The GE DS3800HMACIHIG excels in industrial environments requiring reliable network communication and legacy system compatibility:
- Power Generation: Manages data transmission between turbine control modules, HMIs, and grid synchronization systems, ensuring stable energy production and grid stability.
- Oil & Gas: Enables real-time monitoring of wellhead pressure, pump synchronization, and safety interlocks in offshore platforms and refineries, supporting compliance with environmental and operational standards.
- Heavy Machinery: Facilitates high-speed data exchange between distributed control systems (DCS) and field devices in mining crushers and conveyor systems, enhancing operational efficiency.
- Industrial Automation: Integrates with GE’s Mark IV I/O modules (e.g., DS3800HIOD1G1E digital I/O boards) to enable seamless communication in manufacturing plants, optimizing material handling and process control .

Installation and Maintenance
Installation Preparation: Verify compatibility with the Mark IV system and ensure the control rack’s DIN rail is securely mounted. Align the GE DS3800HMACIHIG with the backplane connector and engage retention levers for a secure fit. Use GE’s TriStation software to configure jumpers for voltage thresholds, signal conditioning, and communication protocols. Anti-static wrist straps are recommended during handling to prevent ESD damage .
Maintenance Recommendations: Regularly inspect connectors for corrosion and clean dust from vents to maintain optimal airflow. Monitor LED indicators for 异常 statuses (e.g., steady red for faults) and address issues promptly. Perform firmware updates as recommended by GE or third-party suppliers. For hardware replacement, retain original jumper settings and terminal configurations for reference. Periodically test diagnostic functions to ensure LED and jumper responsiveness .
Product Assurance
The GE DS3800HMACIHIG is backed by a 1-year warranty covering defects in materials and workmanship, provided by third-party suppliers like AX Control and Amikon. Global technical support is available through authorized service networks, offering troubleshooting assistance, firmware updates, and replacement parts. This ensures minimal downtime and sustained performance for legacy systems.
