DS200AAHAH2A is an ARCNET Connection Board manufactured and designed by General Electric as part of the Mark V LM Series used in GE Speedtronic turbine control systems. The interface connection for ARCNET cables connecting R> to the IO cores and HMI is provided by the ARCNET Connection Board (AAHA). There are two BNC connectors available (channels A and B). The boards in R that contain the ARCNET drivers are connected by one plug connector, the APL connector. The AAHA board and the PANA board's APL or BPL connector are connected by the APL connector. Spot 6 of the R> has two AAHA boards.

The Stage Link between R> and the operator interfaces are designated with one AAHA, denoted as AAHA1 in Appendix B. When using both of the BNC connections on this board, it is possible to connect either two separate Stage Links to a single controller or a different controller to the Stage Link. APL connectors on both AAHA1 and PANA are linked together.

The second AAHA, designated AAHA2 in Appendix B, joins R> to the COREBUS link, enabling communication between the Control Engine and the IO cores. The internal ARCNET link used for Mark V LM controller IO communications is known as COREBUS. To the BPL connector on PANA, the APL connector on AAHA2 is connected.


  • The APL connector connects the AAHA board to the PANA board's APL or BPL connector. Location 6 has two AAHA boards. There is one AAHA labeled for the Stage Link between and the operator interfaces.
  • When both BNC connectors on this board are used, you can connect two independent Stage Links to one controller or another controller to the Stage Link.
  • The AAHA1 APL connector connects to the PANA APL connector. The second AAHA connects to the COREBUS link, which enables the Control Engine to communicate with the IO cores.
  • The internal ARCNET link for Mark V LM controller IO communications is known as COREBUS. The AAHA2 APL connector connects to the PANA BPL connector.
