DMP11 Synchronous Controller
The DMP11 Synchronous Controller is a microprocessor-based intelligent multi-point synchronous serial line interface for the UNIBUS. It uses DMA to transfer data to and from main memory. The DMP11 can operate in either half-duplex or full-duplex, at baud rates up to 1M bits/second (half-duplex) or 512K bits/second (full-duplex); when operating as a control station, it can control up to 32 tributary stations.
It consists of two hex boards:
- a microprocessor module (M8207-YA)
- a line module (M8203), which can be configured to one of 4 choices via jumpers and DIP switches, one of:
