About the DS200AAHAH1A
The DS200AAHAH1A is a GE ARCNET Connection Board (AAHA) for the Mark V LM series of Speedtronic hardware. The Mark V Series that this DS200AAHAH1A printed circuit board product offering belongs to is one of the final General Electric product series to incorporate the patented Speedtronic control system technology into its various offerings; a control system first seen with the introduction of the Mark I Series in the later 1960s. This DS200AAHAH1A printed circuit board or PCB for short is definable as an ARCNET Connection Board, although it is not the original product of its intended functionality to feature within General Electric's Mark V Turbine Control System Series. The original ARCNET Connection Board manufactured for placement in the Mark V Series is the DS200AAHAH1 parent printed circuit board missing this DS200AAHAH1A PCB's A-rated functional product revision. Before making any ultimate purchase decision on this DS200AAHAH1A product offering, it is critical to be cognizant of the fact that this DS200AAHAH1A PCB's greater Mark V Turbine Control System Series is considered to exist as a now-obsolete legacy GE product series, given its eventual manufacturing discontinuation in the many years since its initial release.
Hardware Tips and Specifications
The DS200AAHAH1A is a PCB that has the ability to act as an interface unit that can link various I/O cores or external devices to the <R> Control Engine. This intended functionality necessitates the adoption of several recognizable hardware components to this DS200AAHAH1A board's assembly. The AAHA provides a connection to the ARCNET. There are two AAHA boards used in the <R> core. One acts as a go-between for the <R> core and user interfaces. The APL connector links this board to a UCPB daughterboard that is located on a UCIA board in the <R> core. The second acts as a way to connect a COREBUS to the <R> core. It also facilitates communication between I/O cores and the <R> Control Engine that’s in the <R> core. The APL on this board connects to a PANA daughterboard. The DS200AAHAH1A is a small PCB that has 3 communications ports on the top side. The left port isn’t used very often and is labeled as an EBNC port. Beside of the EBNC are ARCBNC-A and ARCBNC-B ports which are connections for ARCNET communication. On the bottom right-hand-side is a 2-pin 2PL connection port. In the center is an APL 10-pin connection port. This port has the ability to provide a method of communication with boards that have ARCNET drivers and are located in the <R> core. On the bottom left side in the corner is a 9-pin EPL connection that is also not used. For more information about the DS200AAHAH1A, please refer to GE Instruction Manual: GEH-6363B. Generally, this DS200AAHAH1A product has to be considered a fragile Mark V Turbine Control System Series product offering, given the jutting nature of the small above-described BNC ports in its normal Mark V Series assembly. It is a little bit surprising to find out that this DS200AAHAH1A product offering has not been defined as an ARCNET Connection Card by General Electric; given the fact that its relatively-small base printed circuit board dimensions would seem to indicate this with most other Mark V Series products.
Two total BNC connections are established in the normal Mark V Series assembly of this DS200AAHAH1A ARCNET Connection Board. As detailed in the DS200AAHAH1A instructional manual attached above, one of these connectors corresponds to the A and B channels, respectively. The EBNC and EPL Connectors inherent to this DS200AAHAH1A product's normal Mark V Series assembly as they are truly vestigial structures not meant to be even accessed during normative functionality of this DS200AAHAH1A product and its greater Mark V Series automated drive assembly. As a particularly voltage-sensitive General Electric Mark V Turbine Control System Series product offering, this DS200AAHAH1A device will be shipped from our North Carolina warehouse protected by several pieces of padding foam and a specialized voltage-resistant static plastic bag. The above information represents about the extent of viable DS200AAHAH1A ARCNET Connection Board-specific hardware details and specifications available from an analysis of its sparsely-available instructional manual materials. With this in mind, the DS200AAHAH1A functional product number itself, as designed by GE, can be identified as a main source of DS200AAHAH1A board hardware details. The DS200AAHAH1A functional product number begins with the initial DS200 series tag outlining this DS200AAHAH1A product's normal Mark V Series assembly version as well as its domestic manufacture location. Some of the other relevant hardware details revealed in the DS200AAHAH1A functional product number itself include this DS200AAHAH1A board's:
- AAHA functional product abbreviation
- Conformal style of PCB coating
- Group one Mark V Series product grouping
- A-rated functional product revision
