Product Details

The XYCOM XVME-973/1 is a discontinued single-height 6U VMEbus drive adapter module, designed to work with XVME-653 and XVME-658 Pentium VME single board computers, used to route IDE storage signals through the VME backplane P2 connector to external hard disk and floppy storage units. It does not contain storage media itself, acting as a dedicated signal bridge between the host CPU and storage subsystem, and cannot run independently without matching compatible XYCOM SBC.

This adapter board implements standard PC/AT IDE interface signal conversion, including hard disk control signals, data bus, address signals, read/write strobe and IORDY handshake signals. It connects directly to the P2 connector of XVME-653/658 processor via the backplane wiring, and leads IDE signals out to the storage carrier module. It supports both 3.5-inch IDE hard disk and 1.44MB floppy disk drive signals, compatible with DOS and early real-time operating systems, no special driver required for standard IDE devices. The onboard signal conditioning and EMC filter circuits reduce signal reflection and crosstalk on the backplane, improving communication stability in industrial rack environments.

Users need to confirm the host CPU revision, backplane P2 pin definition and IDE device jumper configuration before installation to avoid resource conflict. The module has simple status indicators for power and signal activity, helping maintenance staff check the link status between CPU and storage during commissioning and routine inspection. The PCB adopts industrial-grade vibration-resistant design, suitable for long-term continuous operation in power monitoring systems, chemical control platforms, aerospace test benches and automated test equipment. This legacy drive adapter is mainly supplied as spare replacement parts for existing XYCOM VME automation racks. Users need to verify firmware compatibility between host board and storage devices before deployment. A conformal coated version is optional for high humidity, dusty and corrosive industrial sites. This model is widely used in old VME control system renovation projects to expand IDE storage for Pentium series VME CPU boards.

This drive adapter module adopts standard 6U single-height VME rack mount structure. It draws power from the VME backplane. LED indicators display power and signal status for convenient on-site inspection. The operating temperature range is 0°C to 65°C, storage temperature ranges from -40°C to +85°C, relative humidity 5% to 95% non-condensing. It complies with industrial shock, vibration and EMC standards and has CE certifications. It supports IDE signal configuration backup for fast recovery after hardware replacement.

This XYCOM XVME-973/1 adapter module is widely applied in legacy VME control racks and industrial automation upgrade projects. It serves as the P2 IDE signal bridge for XVME-653/658 SBC to connect external hard disk and floppy storage. As a reliable discontinued spare part, the XYCOM XVME-973/1 retains original IDE timing and backplane signal compatibility, and effectively reduces the renovation cost of legacy industrial control system maintenance.
