General Electric DS200SLCCG3A LAN Communication Card

Configured for high-speed network integration within Mark V and EX2000 control platforms, the GE DS200SLCCG3A (DS200SLCC LAN Communication Card) provides direct physical/electrical execution of LAN-based controller communication.

Hardware Specifications

Industrial Control and Firmware Compatibility

The DS200SLCCG3A facilitates deterministic data exchange across the Mark V backplane. Proper operation is contingent upon backplane bus communication velocity settings that synchronize the LAN control processor with the driver controller processor (DCP) on the SDCC board. Firmware flash compatibility is managed via replaceable EPROMS (U6, U7), which house the LCP software stack. Any replacement of these memory modules requires strict adherence to checksum validation to ensure data integrity during LCP execution. I/O density scaling is supported through the board's dual-ported RAM (U5) architecture, which regulates the data handshaking between the LAN controller and host drive electronics.

Frequently Asked Questions

Q: How is the LCP software updated on the SLCC board?

A: The LCP software is stored in replaceable EPROMS located at U6 and U7. To update, remove the board, extract the existing EPROMS, and install the new programmed EPROMS into the designated sockets while observing static discharge precautions.

Q: What is the purpose of the connector labeled KPPL?

A: The KPPL connector serves as the interface for the programmer module. This module allows operators to perform diagnostic testing, adjust software parameters, and view fault codes via the 16-position alphanumeric display.

Field Installation Guidelines

• Static Sensitivity: The SLCC board utilizes sensitive CMOS components. Always wear a grounded anti-static wrist strap when handling the PCB to prevent permanent damage to the LCP or memory modules.
• Connector Alignment: Ensure all system-level connections to the NTB/3TB, SDCC, and TCCB boards via the 2PL connector are fully seated. Improper seating of the 2PL or 3PL connectors can cause communication timeouts between the LCP and the SDCC.
• Programmer Module: When mounting the programmer module onto the KPPL connector, apply uniform pressure to ensure the pins are correctly aligned and fully engaged to prevent intermittent diagnostic data.
• Component Verification: Before energizing the cabinet, verify that EPROMS U6 and U7 are oriented correctly according to the notch index on the socket. Reverse installation will result in immediate boot-up failure.
• Grounding: Ensure the board is properly secured to the cabinet chassis via its mounting screws to maintain the integrity of the isolated and non-isolated circuit grounding paths.
