DS200SLCCG1AEE, Open-Box Spare Stock

This DS200SLCCG1AEE is a G1-group SLCC – GE's LAN Communication Card for the Speedtronic Mark V system, offered here as new-surplus, open-box material. The SLCC's job is to process and filter incoming LAN communication signals through isolated and non-isolated circuits, built around a LAN Control Processor (LCP, U1) whose software lives in two replaceable EPROMs (U6/U7) with dedicated RAM at U8/U9. A dual-ported RAM at U5 links the LCP with the drive control processor on the SDCC card via connector 3PL, and an attachable alphanumeric keypad/display module gives access to configuration and fault-code readout.

The card belongs to the documented set in the Mark V's <C> (communication) core, connecting to the NTB/3TB, SDCC, TCCB, and DCFB boards through a 2PL connector. Being G1-group, it includes the DLAN and ARCNET network adaptation circuitry that a later G4 group removed entirely, so the group letter reflects a real hardware difference rather than a simple batch marker.

About the Open-Box Condition

Open-box in our listings means genuine new-surplus, factory-sourced stock that has been removed from its original retail packaging – usually for inspection or inventory handling – but never installed or field-used. It carries the same 1-year warranty as our other new-surplus boards; ask for a label photo with your quote request if you'd like to confirm cosmetic condition ahead of time.

Know How to Diagnose an SLCC Fault Before You Need This Spare

Because a board like this is often bought for a spares program, it's worth understanding in advance how often SLCC-shaped symptoms turn out to be something else. In one documented Mark V case, the operator interface stopped updating live data, and the site replaced every card in the <C> core (SLCC, TCCA, SDCC, TCDA) plus the TCPS power supply – and the fault didn't clear. What eventually pointed to the real cause:

• Power supply voltages at the <R> and <C> test points, checked against Mark V Maintenance Manual (GEH-5980) limits
• The BOI (backup operator interface), which talks to <R> directly, bypassing <C>
• Connector corrosion or a broken cable conductor, ahead of a card swap
• The TCQC card in <R> and its ARCPL link to the <C> core's SLCC – faults here mimic a bad SLCC exactly

And remember that a processor core reaches I/O status A7 only once every card inside it individually reaches A6 – identify the specific holdout card before assuming it's the SLCC.

Reading DS200SLCCG1AEE

DS200 is the Mark V-era board series prefix, SLCC is the LAN Communication Card acronym, G1 is the product grouping (with DLAN/ARCNET circuitry), and EE is this unit's specific revision combination. Since SLCC groups reflect genuine circuitry differences, confirm the exact group your system requires before ordering.

Related Boards and Longer-Term Options

Inside the <C> core, the SLCC works with TCCA, SDCC, IOMA, TCDA, and the TCQC card linking back to <R>. If your facility is weighing a platform migration, GE's Mark VI system replaced the DS200 series with IS200-series boards and a different communications architecture; see our Mark V vs Mark VI: DS200 to IS200 guide. For GE's part-numbering logic, see the GE Speedtronic Part Number Decoder, and for the SLCC's place in the DS200 lineup, see GE Mark V DS200 Boards Explained.
