FOXBORO FBM241 P0914TG Channel relay module

The 82596CA is used to implement the Ethernet transceiver interface. The 82596CA accesses local RAM using DMA operations to perform its normal functions. The Ethernet transceiver interface is located on the MVME167, and the industry-standard connector is located on the MVME712X transition module. Every MVME167 is assigned an Ethernet Station Address. The address is $08003E2xxxxx where xxxxx is the unique 5-nibble number assigned to the board (i.e., every MVME167 has a different value for xxxxx).

Buffer Overruns

Because the 82596CA has small internal buffers and the VMEbus has an undefined latency period, buffer overrun may occur if the DMA is programmed to access the VMEbus. Therefore, the 82596CA should not be programmed to access the VMEbus. Support functions for the 82596CA are provided by the PCCchip2. Refer to the 82596CA user's guide for detailed programming information.

SCSI Interface

The MVME167 provides for mass storage subsystems through the industry-standard SCSI bus. These subsystems may include hard and floppy disk drives, streaming tape drives, and other mass storage devices. The SCSI interface is implemented using the NCR 53C710 SCSI I/O controller. Support functions for the 53C710 are provided by the PCCchip2. Refer to the 53C710 user's guide for detailed programming information.
