The GE DS200MBHAG2A DS200MBHAG2AFC multi-bridge hub communication board centralizes data exchange for Mark V systems. This board connects multiple serial devices and networks to the main controller. You will find this hub board in turbine control cabinets with extensive field device networks. Its multi-port design eliminates the need for external hubs.
Communication Hub Architecture
This multi-bridge board uses a 32-bit processor for routing and protocol conversion. Consequently, it handles simultaneous communication across all ports without delays. The GE DS200MBHAG2A DS200MBHAG2AFC provides six serial ports and two Ethernet interfaces. Moreover, onboard memory buffers data during peak network traffic. You can configure each port independently for different devices.

Multi-Port Connectivity and Routing
The unit includes six software-selectable RS-232/485 serial ports. Therefore, you can connect legacy devices without external converters. This board replaces the DS200MBHAG2AFC version without any configuration changes. Simply remove the old board and install this one. GE designed this hub board for hot-swappable installation. Hence, you can replace it without shutting down the turbine.
Eight PCB layers separate high-speed communication traces from power circuits. Nine connectors handle all Ethernet, serial, and power signals. The GE DS200MBHAG2A DS200MBHAG2AFC holds 2200 µF of capacitance for stable operation. Accordingly, it maintains communication during minor power fluctuations. Nine status LEDs show power, link, activity, and fault conditions clearly.
Protocol Handling and Installation Guide
The onboard processor routes messages between different protocol types. You can connect Modbus devices to a Profibus network seamlessly. The GE DS200MBHAG2A DS200MBHAG2AFC works with all GE Mark V control systems. Always use shielded cable for serial connections longer than 15 meters. Proper termination of RS-485 networks prevents signal reflections.
Each serial port includes selectable termination resistors for network flexibility. The board stores routing tables in non-volatile flash memory. The GE DS200MBHAG2A DS200MBHAG2AFC delivers reliable multi-bridge communication for complex systems. Installation requires only a screwdriver for power and serial connections. This board operates in non-condensing environments with adequate ventilation.
