EPC-1MS RadiSys Mass Storage Module

RadiSys EPC-1AM
The RadiSys EPC-1AM adapter module is designed to accept 8-bit PC/AT short cards (up to 5.75 inches long). The EPC-1AM has three components: a front panel, a circuit board, and a replacement SCSI disk cable. The circuit board has an edge connector and a sliding bracket which allow a PC/AT short card to be mounted upside down with its panel connector facing the front of the VMEbus card cage. On the back of the adapter module circuit board is a 96-pin female connector which plugs into a matching pin group on the outer board of the EPC-1P CPU module.

Because it typically resides between the CPU and disk modules in an EPC-1 system, the adapter module circuit board has two rectangular holes through which the SCSI and floppy drive cables may pass. Diskless network nodes consist of the adapter and CPU modules, along with the appropriate networking card and software.

RadiSys EPC-1GE
The RadiSys EPC-1GE processor module comes configured for use with a GE Fanuc Series 90-70 PLC acting as slot-1 controller. The EPC-1GE is used in conjunction with the EPC-1MS mass storage module and an EGA monitor. All the switches necessary for modifying this configuration are in a single DIP switch block on the top board of the processor module.

RadiSys EPC-1SE
The RadiSys EPC-1SE SCSI extension module allows you to use an external SCSI device with your EPC-1. The EPC-1SE consists of a single-slot front panel with a standard D-subminiature SCSI connector (with bail fasteners) on a 50-pin SCSI cable. The SCSI cable has two 50-pin female connectors: one attaches to the hard disk on the EPC-1MS mass storage module; the other attaches to connector pins on the EPC-1P CPU module.

The EPC-1SE is designed to reside in the slot immediately to the right of the EPC-1MS (or immediately to the right of the EPC-1P if no mass storage module is present).
