Designed as PCMCIA plug-in module, the PC Node allows the communication between a notebook and the MVB/AF100.
This board is being used as a maintenance and diagnostic interface within the train control automation – MVB. Once inserted in a notebook, the PC Node is accessible as a standard PCMCIA card.
The design includes the entire logic of the PCMCIA-Slave interface inclusive the CIS table. Among other things the ASIC contains also an interface, which allows reading and writting of the "Traffic Memory" from the notebook.
A local processor system - Motorola MC68340 & 1MB SRAM & 2MB Flash – off-loads the PC from the computing intensive tasks for the bus administrator functionality.
