Product Description

The DS200AAHAH1A is a GE ARCNET Connection Board (AAHA) for the Mark V LM series of Speedtronic hardware.

The DS200AAHAH1A is a PCB that has the ability to act as an interface unit that can link various I/O cores or external devices to the <R> Control Engine. The AAHA provides a connection to the ARCNET. There are two AAHA boards used in the <R> core. One acts as a go-between for the <R> core and user interfaces. The APL connector links this board to a UCPB daughterboard that is located on a UCIA board in the <R> core. The second acts as a way to connect a COREBUS to the <R> core. It also facilitates communication between I/O cores and the <R> Control Engine that’s in the <R> core. The APL on this board connects to a PANA daughterboard.

The DS200AAHAH1A is a small PCB that has 3 communications ports on the top side. The left port isn’t used very often and is labeled as an EBNC port. Beside of the EBNC are ARCBNC-A and ARCBNC-B ports which are connections for ARCNET communication. On the bottom right-hand-side is a 2-pin 2PL connection port. In the center is an APL 10-pin connection port. This port has the ability to provide a method of communication with boards that have ARCNET drivers and are located in the <R> core. On the bottom left side in the corner is a 9-pin EPL connection that is also not used.
