The MVB PC/104 is an interface module with which it is possible to connect electronic controllers to the MVB.
The user of the MVB PC/104 module is provided with API software for their development.
The MVB PC/104 connects the parallel PC/104 bus with the serial MVB. Data exchange from the MVB to the PC/104 bus and vice versa is performed via the traffic memory. Arbitration of the traffic memory is performed by the MVBCS1 ASIC.
The module is designed for use with a 16-bit CPU with ready acknowledgment. Bytewise accesses to the traffic memory are not possible because of its wordwise organization. Accesses must always be wordwise (only to even addresses).
