About the DS200AAHAG2A
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
- P1 and P2 ARCBNC-B and ARCBNC-A ports
- a 2PL connection
- 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.
