Functional Description

DS3820MAUD is a Media Access Module manufactured and designed by General Electrics. It is a part of the Mark IV Control System. A Media Access Module is an component in control system, facilitating communication between devices and system controllers. It features an interface panel with multiple labeled ports, such as Cable A, Cable B, and power connections, ensuring seamless connectivity. The module also integrates diagnostic tools, including LEDs and test points, to monitor system performance and enable quick troubleshooting. Its robust design supports secure mounting and compatibility with various communication cables.

Features and Components

• Interface Panel: The module features a well-structured interface panel that connects directly to the PCB (Printed Circuit Board). The panel includes three cutouts, each serving a specific monitoring purpose Cable A OK, Cable B OK, Watch Dog Timer OK.
• Labeling and Connectivity: Clear labels and directional lines connect these indicators to corresponding ports on the panel’s edges.
  
  • Cable A: Marked with endpoints JB and JC.
  • Cable B: Marked with endpoints JD and JE.
• Two labeled boxes appear at the top of the panel: JA/Link Controller Connector, JG/Power Connector.
• Connection Ports: Four ports on the panel's side provide cable connections for JB, JC, JD, and JE. Below these ports are six screw connections, which secure the interface panel firmly to the PCB.
• Back Panel Design: The backside of the interface panel is connected using two pins, which slide over two vertical nylon spacers mounted on the board, ensuring stability and easy assembly.
• Indicators and Test Points: The PCB is equipped with six red LEDs, perfectly aligned with the cutouts on the interface panel for real-time status monitoring. These LEDs provide visual feedback for cable and timer statuses.
• Connectors and Headers: Includes one PCB mating connector (218A4837-P12). A six-pin header facilitates secure and flexible connections. Six TP test points are provided for troubleshooting and diagnostics.
