Product Introduction
GE DS200SLCCG1ACC is a LAN communication board for the GE Speedtronic Mark V control system family. It is designed as a G1-series SLCC board to provide the host drive with the processor and interface circuits required for LAN communication.
The board provides both isolated and non-isolated communication circuits for the host drive. All signals sent to the board are processed through an integrated LAN Control Processor (LCP), which serves as the key processing point on the board.
LCP program memory is stored in two onboard EPROM memory modules. Communication between the LCP and the connected drive control board is executed through onboard dual-port RAM.
As a G1-series SLCC board, DS200SLCCG1ACC supports both DLAN and ARCNET network connections, allowing the drive system to communicate within the Mark V control architecture.
The board may be equipped with an optional 16-key alphanumeric programmer/keyboard that provides access to system control settings and diagnostics when connected.
Some third-party listings describe DS200SLCCG1ACC as an RST analog I/O (TCQA) board used in gas turbine I/O cores. That description conflicts with the SLCC LAN communication board definition and should not be treated as authoritative without verification against the physical board label and GE documentation.

Note: The SLCC LAN communication function, DLAN/ARCNET support, LCP processor, dual EPROM modules, dual-port RAM, and optional alphanumeric keyboard are documented for the DS200SLCCG1A family. The exact connector layout, jumper map, LED indicators, EPROM content, and ACC-specific configuration should be verified from the physical board label and GE Mark V manuals.
Quality Control Process (DYNAMIC GENERATION)
- Visual and label inspection. We check the part number, suffix, PCB surface, connectors, EPROM modules, LCP chip, and mounting hardware for damage or corrosion.
- SLCC function verification. We confirm the board matches the DS200SLCCG1ACC LAN communication board description and is not mislabeled as a TCQA/analog I/O board.
- EPROM and memory check. Both EPROM modules are inspected for correct seating and labeling; dual-port RAM area is checked for visible damage.
- Connector and continuity check. All board connectors are verified for correct pin continuity and no short circuits.
- Final packaging. After passing inspection, the board is anti-static bagged and foam-packed for shipment.
Replacement Pitfall Guide (DYNAMIC GENERATION)
❗ Confirm SLCC function before installation. DS200SLCCG1ACC is a LAN communication board; do not substitute it with TCQA, SDCC, SDCI, or other Mark V I/O boards.
❗ Ignore conflicting third-party descriptions. Some listings describe this part number as a TCQA analog I/O board; that conflicts with the SLCC LAN communication board definition.
❗ Transfer EPROM modules from the original board if required. The LCP program memory resides in two EPROM modules; replacement boards may ship with empty EPROM slots.
❗ Label all connectors before removal. Miswiring DLAN/ARCNET or drive control connections can cause communication failures or drive faults.
❗ Record jumper and keyboard settings before removal. Document jumper positions and keyboard connections for troubleshooting reference.
❗ Verify network compatibility. Confirm the board supports the correct DLAN and ARCNET configuration for your Mark V system before replacement.
❗ Handle as ESD-sensitive equipment. Always use anti-static wrist straps and handling procedures during removal, installation, and storage.
Keep these in mind and you’ll cut 90% of rework time.
Compatibility Matrix & Benchmarks
| Original Model | Replacement / Successor Model | Compatibility Level | Migration Notes |
|---|---|---|---|
| GE | GE | Direct | Same part number; verify EPROM content and jumper settings. |
| GE | GE DS200SLCCG1A variants | Needs Adaptation | Same SLCC family; suffix differences may affect revision or configuration. |
| GE | GE DS215SLCCG1A variants | Needs Adaptation | DS215-level boards may include pre-loaded EPROMs; verify compatibility. |
| GE | GE DS200TCQA / DS200SI0CG1AEA | Not Compatible | TCQA is an RST analog I/O board; not a direct replacement. |
| GE | Mark VIe / IS200/IS220 modules | Not Compatible | Different platform and architecture; not a direct replacement. |
