Firmware Flash Compatibility & Communication Bus Processing

The DS200SLCCG3A manages LAN data arbitration across isolated and non-isolated communication circuits via the onboard LAN Control Processor (U1). Firmware flash compatibility and software execution are maintained through socketed, replaceable EPROMs (U6, U7), paired with dedicated RAM modules (U8, U9). The board executes high-speed data transfer to the Driver Controller Processor (DCP) on the DS215SDCC Drive Control Card via dual-ported RAM (U5) routed through the 3PL connector. Hardware diagnostic monitoring and parameter adjustments are handled through the 16-position alphanumeric display driven by U-18 and the KPPL programmer module interface.

Frequently Asked Questions

Q: How does the DS200SLCCG3A communicate with the main DS215SDCC Drive Control Card?

A: Communication is executed via the dual-ported RAM IC (U5) through the 3PL connector interface directly to the Driver Controller Processor (DCP).

Q: Can the firmware on the DS200SLCCG3A card be updated in the field?

A: Firmware is stored on socketed EPROMs (U6 and U7), which can be physically replaced to update the LAN Control Processor (LCP) software version.

Q: What hardware interface is used to connect external diagnostic programmer modules?

A: External programmer modules attach directly to the onboard KPPL connector, interacting with the 16-position alphanumeric display and U-18 controller.

Field Installation Guidelines

  • De-energize the Mark V or EX2000 cabinet and ensure all power supplies are isolated before removing or inserting the board.
  • Wear a grounded ESD wrist strap connected to the enclosure frame to prevent static discharge to onboard semiconductors during handling.
  • When replacing EPROMs (U6, U7), ensure correct pin orientation and alignment within the socket contacts to prevent IC pin damage.
  • Inspect all ribbon cable connections (2PL, 3PL, KPPL) to ensure complete engagement and proper latching before applying power to the drive rack.
