Functional Description

IS200BAPAH1A is a Analog Processor developed by GE. It is a part of Mark VIe control system. The component pressure inputs and sensor power outputs can be used with non-sparking (nA) devices when properly wired in Class I Division 2 or Zone 2. The product delivers reliable analog signal conditioning, high-resolution A/D conversion, flexible and customizable signal processing, efficient FPGA booting, and robust power supply capabilities. These features collectively enhance the performance, versatility, and functionality of the product.


  • Eighteen Analog Signal-Conditioning Channels: Includes eighteen channels dedicated to signal conditioning. These channels feature differential inputs, allowing for accurate measurement and processing of analog signals. Additionally, the processor offers adjustable gains of 1x, 2x, 4x, and 8x, providing flexibility to accommodate different signal amplitudes. It also supports DC bias nulling, allowing for precise offset adjustment. The presence of a multiplexer enables the bypassing of signal inputs and application of test signals, facilitating testing and troubleshooting. Furthermore, anti-alias filters are included to support a bandwidth of up to 5 kHz, ensuring accurate and reliable signal processing without aliasing artifacts.
  • Twenty-four A/D Input Channels: Integrates twenty-four A/D (Analog-to-Digital) input channels, distributed across six channels per converter. These channels enable the conversion of analog signals into digital format for further processing and analysis. The processor employs 16-bit converters, ensuring high-resolution and accurate digitization of analog signals.
  • Application FPGA: Incorporates an application FPGA (Field-Programmable Gate Array), which plays a crucial role in signal processing and control functions. The FPGA is responsible for controlling the A/D and D/A converters, facilitating the conversion of analog and digital signals. It also handles eighteen channels of Finite Impulse Response (FIR) filtering, allowing for advanced digital signal processing operations. Configuration registers within the FPGA store various settings and parameters, enabling customization and flexibility in system configuration. Additionally, the FPGA includes HSSL (High-Speed Serial Link) control for efficient communication between different components within the MicroNet platform.
  • Booting FPGA with Programmable Read-Only Memory (PROM): Incorporates a programmable read-only memory (PROM) that facilitates the booting of the FPGA. This bootstrap function ensures the proper initialization and configuration of the FPGA upon system startup. The processor also features TX/RX mini-MACs (Media Access Controllers) and PHY (Physical Layer) sync, enabling reliable communication over the Ethernet interface. It incorporates PHY0 and PHY1 physical Ethernet layers for seamless connectivity and network integration.
  • Power Supplies: Includes several power supplies to ensure proper voltage levels for its operation. It features a P28 input, which serves as the primary power input. The processor provides P15 and N15 outputs, delivering positive and negative 15V voltages, respectively. Additionally, it offers a P5 output, supplying 5V voltage.�the module� provides 3.3V, 2.5V, and 1.2V outputs, delivering the corresponding voltages to support various internal components and subsystems.


  • PWR LED: When 28 volts of power is supplied to the system, the PWR LED displays a solid green light. This indicates that the power source is connected and providing the necessary voltage for the system to operate. The continuous green light confirms the presence of power and assures users that the system is ready for operation.
  • ATTN LED: Upon powering on the system, the ATTN LED initially displays a solid red light for approximately half a second. This brief red illumination serves as a power-on indicator, indicating that the system is being initialized. After this brief period, the ATTN LED goes dark, indicating that the initial power-on sequence is complete. The extinguishing of the LED after the red illumination signifies that the system is transitioning to its operational state.
  • BAPA Configuration LED: If a valid serial link is established between the system and the host UCSA (Universal Serial Communications Adapter), the BAPA (Board Auxiliary Processor Assembly) will receive the necessary configuration information from the host UCSA. Upon successful receipt of the configuration, the BAPA Configuration LED will turn solid green. This green light indicates that the BAPA has been properly configured and is ready for operation. The solid green LED serves as a confirmation that the system has established a valid connection with the host UCSA and is configured according to the required parameters.
  • High-Speed Serial Link LED: The high-speed serial link interface on the BAPA is designed to establish a proper link with a UCSA serial port. When this link is established successfully, the High-Speed Serial Link LED displays a solid green light. The solid green illumination indicates that the high-speed serial link interface has established a reliable and functional connection with the UCSA serial port. This LED serves as a visual confirmation of the successful link establishment between the BAPA and the UCSA serial port.
  • Tx/Rx LED: The Tx/Rx LED represents the packet traffic on the high-speed serial link. When there is data transmission or reception occurring on the serial link, this LED blinks in green. The blinking green light serves as a visual indicator of the packet traffic activity, confirming that data is being transmitted or received over the high-speed serial link. This LED provides users with a real-time visual feedback of the system's communication activity.

Replacement Procedure

  • Isolate the power source and lockout/tagout the field equipment: Before starting the replacement procedure, it is crucial to isolate the power source that supplies electricity to the equipment where the module is installed. This involves shutting off the power and taking necessary precautions to prevent accidental power restoration. Additionally, lockout/tagout procedures should be followed to secure the equipment, ensuring that it cannot be energized while the replacement is taking place. This step prioritizes safety during the replacement process.
  • Unplug the HSSL Ethernet cable from the to-be-removed module: Locate the HSSL Ethernet cable that is connected to the module being replaced. Carefully unplug the cable from the module, ensuring that no strain is exerted on the cable or the module's connectors. It is important to handle the cable with care to avoid any damage to its connectors or the cable itself.
  • Remove any cord ties that are holding the cable to the module: Inspect the module and the associated cables for any cord ties or fasteners that secure the HSSL Ethernet cable to the module. Remove these cord ties, taking care not to damage the cable or other components. This step allows for the smooth removal of the module without any obstructions.
  • Remove the BAPA module by unscrewing the retaining hardware: Identify the retaining hardware (such as screws) that secures the BAPA module in place. Using the appropriate tools, carefully unscrew and remove the retaining hardware while supporting the module. Be cautious not to drop any screws or other small components during this step. Once the retaining hardware is fully removed, gently slide the module out of its slot.
  • Insert the new module into the old module's location and securely tighten the retaining hardware: Take the new module that is intended to replace the old one. Align the new module with the vacant slot previously occupied by the old module. Insert the new module into the slot, ensuring a proper fit and alignment with the surrounding components. Once in place, use the appropriate tools to securely tighten the retaining hardware, ensuring that the module is firmly held in position.
  • Connect the HSSL Ethernet cable to the module and secure it: Take the HSSL Ethernet cable that was previously disconnected from the old module. Align the cable's connectors with the corresponding ports on the new module. Gently insert the connectors into the ports, ensuring a secure and proper connection. Once connected, secure the cable to the module using cord ties or other appropriate fasteners, ensuring that the cable is properly routed and protected.
