GNP Computers PDSi Wide SCSI Terminator 1-502094 Rev A PCB Module

This is a Wide SCSI terminator board made by GNP Computers for use with PDSi-series systems. The board carries part number 1-502094, Rev A, with a date code of 990107. SCSI bus terminators are passive or active components required at each end of a SCSI bus chain to absorb signal reflections and maintain proper bus impedance. Without proper termination, a SCSI bus can suffer data errors, device detection failures, or instability — making the terminator a critical but often overlooked component in any SCSI storage configuration.

Applications

Wide SCSI (also called SCSI-2 Wide or Ultra Wide SCSI depending on generation) uses a 68-pin bus and was a common storage interface in workstations, servers, and industrial computing platforms through the late 1990s and into the early 2000s. GNP Computers produced the PDSi line of computing and data acquisition systems, and this terminator was designed for use with those platforms. Proper termination is required at the physical end of the SCSI chain — either internally inside a chassis or at the last external device. This board serves that role, providing the bus with a defined signal endpoint. Replacement terminators like this one are still in demand for maintaining legacy SCSI-based workstations, industrial controllers, and data acquisition systems where upgrading the storage bus is not practical.
