Description
GNP Computers 1-503153C1 cPCI RTM Wide SCSI I/O Rear Transition Module 6U
The GNP Computers 1-503153C1 is a 6U CompactPCI (cPCI) Rear Transition Module (RTM) providing Wide SCSI I/O connectivity for PDSi cPCI systems. It mounts at the rear of a 6U cPCI chassis and mates with the host processor or SCSI controller card via the P3 and P5 backplane connectors, routing Wide SCSI signals to external devices through front-accessible 68-pin HD connectors labeled SCSI-OUT and SCSI-IN.

Applications
Rear Transition Modules are a standard part of CompactPCI system architecture. In a cPCI chassis, the main I/O and processing cards plug into the front of the backplane, while RTMs mount at the rear and provide the external I/O connectors that would otherwise crowd the front panel. The 1-503153C1 specifically routes Wide SCSI bus signals — the 16-bit wide variant of the SCSI-2/SCSI-3 parallel interface that was the dominant high-performance storage and peripheral bus in embedded and industrial computing through the 1990s and into the 2000s. Wide SCSI supported data transfer rates up to 40 MB/s (Ultra Wide SCSI) and was widely used for connecting disk arrays, tape drives, and other high-throughput peripherals in mission-critical and real-time systems. GNP Computers was a well-known developer of CompactPCI single-board computers and embedded systems targeting defense, aerospace, industrial automation, and telecommunications applications. The PDSi product family used 6U cPCI as its core platform, and RTMs like this board were essential for cleanly routing I/O to the rear of the chassis in rack-mounted deployments. This module would be relevant to integrators maintaining or expanding legacy GNP Computers PDSi cPCI systems that require Wide SCSI peripheral connectivity.
This GNP Computers 1-503153C1 cPCI RTM Wide SCSI I/O Rear Transition Module has been inspected and is in good condition. The board is clean with no visible damage to the PCB, connectors, or card handles. The front-panel 68-pin SCSI-OUT and SCSI-IN connectors appear undamaged and the P3/P5 backplane connectors on the rear are intact. Normal light wear consistent with previous installed use is present.
