Functional Description

DS3820MAUD1A1B is a Freeway Media Access Module developed by GE. It is a part of the Mark IV control system. The module is also known as the Directo-Matic Plus Control System Freeway Media Access Module and functions as a interface component within the larger Mark IV architecture.

Design and Front Panel Configuration

The module incorporates a compact and functional HMI (Human-Machine Interface) panel, designed for connectivity, monitoring, and diagnostic purposes. Key elements include:

• Cable Connectors: Four cable connectors are prominently positioned on the front panel
  • JB and JC for Cable A
  • JD and JE for Cable B
  • These connections enable secure integration into the control system, providing data and communication pathways.
• Indicator Cutouts: The front panel features three labeled cutouts, corresponding to operational status indicators.
  
  • Cable A OK
  • Cable B OK
  • Watch Dog Timer OK
  • These cutouts allow visibility of internal status LEDs, facilitating quick diagnostics.
• Additional Connectors:
  • JA-Link Controller Connector: Serves as a communication link.
  • JG-Power Connector: Supplies power to the module.

Features

• It features six light-emitting diodes (LEDs) that align with the front panel cutouts, providing real-time indications of system status and alerts for efficient diagnostics.
• The board includes a six-pin header and a PCB mating connector marked 218A4837-P12, ensuring compatibility and secure integration with other components.
• For troubleshooting and monitoring, the PCB has six labeled test points: RXA, RXB, RCFG, DCOM, OXMIT, and 1RCV, each serving specific diagnostic purposes.
• Additionally, ten jumpers are incorporated into the board, allowing flexible configuration and system adjustments as needed. These features collectively enhance the module's functionality and reliability.
• LEDs and status indicators provide immediate feedback on system health.
