Internal Design and Communication Processing
This communication board uses a 16-bit CPU for protocol handling and data buffering. Two UARTs manage simultaneous serial communication on multiple ports. The GE DS200STCAG1A DS200STCAG1ABA supports Modbus RTU and GE proprietary protocols. Flash memory stores the board’s firmware for field updates. A super capacitor retains configuration data for 72 hours during power loss. Consequently, this board enables reliable data exchange between turbine systems and external networks.
Installation and Wiring Guide
First, mount this communication board onto standoffs inside your control cabinet. Next, connect a 24 V DC power supply to the designated terminals. Then, wire your RS232 devices to the 9-pin SUB-D ports using shielded cables. Connect your RS422/485 network to the terminal block for multi-drop communication. Configure the baud rate and protocol using the onboard DIP switches. The board automatically buffers incoming data for the main processor. This communication board works with all Mark V turbine control systems and compatible Modbus devices. Always terminate the RS422/485 line with proper resistors for long cable runs.
