Product Description
The DS200AAHAG2A is a MARK V LM Speedtronic ARCNET HUB LAN Drive Board. This board was originally created by GE but is now a legacy series module that no longer receives any support from GE. Despite this, AX Control does try to keep this board in stock when available surplus presents itself on the market. While a legacy series, this DS200AAHAG2A PCB's greater Mark V Series is additionally considered to exist as one of the final General Electric Mark product series to make use of their Speedtronic control system technology first seen alongside the rollout of the Mark I Series in the later 1960s. This DS200AAHAG2A ARCNET HUB LAN Drive Board is not the originally-developed product of its functional role to make an appearance in the Mark V Series; that would be the DS200AAHAG2 parent ARCNET HUB LAN Drive Board missing this DS200AAHAG2A device's standard A-rated functional product revision.
Hardware Tips and Specifications
The DS200AAHAG2A is also known as an ARCNET Connection Board (AAHA). It was made to be a part of the control panel in a Mark V system. The AAHA board has the ability to connect external devices to the Control Engine which is a part of the <R> Core. It uses the ARCNET connections to accomplish this. The <R> core actually uses two of these boards for slightly different purposes. One AAHA board is used for facilitating a Stage Link between different operator interfaces and the <R> core. The other AAHA board is used to grant the <R> core communication to the COREBUS network. Making this connection will encourage communication between the Control Engine and the I/O cores within the <R> core. This board also connects to the PANA board using the APL connector. The features of the DS200AAHAG2A (AAHA) are as follows:
- Two connection ports.
- The two other ports on the right side labeled P1 and P2 are ARCBNC-B and ARCBNC-A ports.
- Below the P1 connector is a 2PL connection. On the bottom right corner of the board is an APL 10-pin connector that is used to provide a communications link between the AAHA board and the boards that contain the ARCNET driver within the <R> core.
Each one of these connectors, as with any individual hardware component in this DS200AAHAG2A printed circuit board's assembly, is accompanied by its own factory-printed nomenclature label for convenient identifications purposes. Some of this DS200AAHAG2A device's included connectors outside of the APL connector are the 2PL TCPS Board R Core Connector, the ARCBNC A and ARCBNC C ARCNET BNC Connectors, and the EBNC and EPL Connectors. Each of these connectors have been named through a combination of their functionality within the Mark V Series automated drive assembly, their aforementioned nomenclature labels, and their Mark V Series interfacing potential with other PCBs. The EBNC and EPL Connectors in this DS200AAHAG2A PCB's assembly have not been named as they are both vestigial structures intended to go unused during normative functioning of the DS200AAHAG2A PCB and its greater automated drive assembly.
