GE DS200AAHAH1A Mark V LM ARCNET Connection Board

DS200AAHAH1A provides the AAHA cable interface for the Mark V LM ARCNET network. In the system described by GEH-6153, AAHA connections link the control engine with operator interfaces or I/O cores according to the board’s assigned network role.

DS200AAHAH1A uses the AAHA interface with two ARCNET BNC connections, ARCBNC A and ARCBNC B. Their cabling depends on the installed Stage Link or COREBUS arrangement; the two external connections must not be mistaken for Ethernet ports.

DS200AAHAH1A uses APL for the internal ARCNET connection to PANA. GEH-6153 connects the Stage Link AAHA board to PANA APL and the COREBUS AAHA board to PANA BPL, so the correct destination depends on the installed board role.

DS200AAHAH1A belongs to the AAHA connection-board family. The documented controller uses AAHA1 for Stage Link communication with operator interfaces and AAHA2 for the internal COREBUS link to I/O cores; match the installation’s assigned cable path.

DS200AAHAH1A has no board-level hardware or software configuration in the AAHA description. GE places the related ARCNET address settings on PANA. AAHA and PANA have different functions, so changing a cable interface does not define a new network address.

DS200AAHAH1A must be used within the documented ARCNET installation arrangement. For Stage Link, GEH-6153 requires a 93-ohm terminating impedance at both ends and prohibits loops; use the system topology rules rather than treating the cable as an unrestricted network.
