Features:
- Implements Group 4 local communication without DLAN or ARCNET hardware.
- Transfers selected processor data through the SDCC exchange buffer.
- Uses group-specific grounding provisions at designated signal points.
Group identity is essential for
DS200SLCCG4A because its communication scope differs from network-equipped SLCC versions. The absence of DLAN and ARCNET hardware is part of the board definition, not a missing option.
Controller information on
DS200SLCCG4A passes through the shared buffer and the 3PL inter-card route. Local computation remains on the LCP side until data are presented to the SDCC.
Ground references on
DS200SLCCG4A follow the G4 assignment for WJ2-WJ5. Keeping those provisions with the correct group prevents an unused network point from being interpreted as an active channel.
The General Electric DS200SLCCG4A Group 4 LAN Communications Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Group 4 Boundary
- DLAN: Group 4 does not implement the DLAN circuitry.
- ARCNET: No ARCNET module is assigned to this hardware group.
- Local Processing: The LCP and its memory devices remain active.
- Interpretation: Absent network response is expected for interfaces not fitted.
Controller Handoff
- U5 Buffer: Dual-ported memory separates LCP and DCP access.
- 3PL Route: Controller-bound traffic leaves through the SDCC connection.
- 2PL Route: The DCFB or SDCI side supplies its distinct power-and-data path.
- Isolation: A fault can be localized to one connector boundary.
Group-Specific References
- WJ2-WJ5: These provisions assign designated communication points to ground.
- Group Match: The pattern belongs to the G4 board arrangement.
- Unused Paths: Grounding distinguishes inactive network points from signal inputs.
- Wiring Rule: Host connections must follow the G4 cabinet documentation.
On-board Interaction
- Operator Port: Local programming and status use the dedicated service connection.
- Status Path: Display functions are controlled by the LCP side.
- Program Devices: U6 and U7 establish the operating-code context.
- Check Order: Local access can be tested before the SDCC exchange route.
