Product Description

The DS200AAHAG1AD is an ARCNET connector board manufactured by General Electric as part of the Mark V LM SpeedtronicTurbine control system.

Mark V LM manual GEH-6353B clearly summarizes the function of the DS200AAHAG1AD in the control system. The board is referred to by its acronym AAHA.

The DS200AAHAG1AD, abbreviated AAHA, is part of the Speedtronic Mark V LM control panel.

The board is capable of providing connectivity and interface functionality between a control engine with an I/O core and external hardware.

The control engine is typically located within the core. The kernel typically requires the use of two AAHA boards.

One board is used to facilitate the stage link between the user interface and the core.

The second board is capable of connecting the core to COREBUS.

This link allows communication between the I/O core and the control engine.

The DS200AAHAG1AD is plugged in and installed to operate without any type of hardware or software modification.

The AAHA board is relatively small. It has an EBNC connection port that is not normally used.

It has one ARCBNC-B labeled P1 and one ARCBNC-A port labeled P1.

These ports are BNC ARCNET communication ports. There is an E2 and E1 LED indicator.

There is an EPL 9-pin connection that is not normally used and an APL 10-pin connection port that is used as an ARCNET communications link.
