Description
DataMate DM2750-02-68ADR Active SCSI Terminator Single-Ended 68-Pin SCSI-2 HD
The DataMate DM2750-02-68ADR is a single-ended active SCSI terminator in a compact external plug-on form factor. It fits directly onto a 68-pin High Density (HD) SCSI-2 connector and provides active termination (ADR type) at the end of a SCSI bus. The label on the unit confirms model DM2750-02-68ADR, date code 9739, Type ADR, Patent 5362991, and PWN 8003236858.

Applications
SCSI terminators are required at both physical ends of a SCSI bus to prevent signal reflections that cause data errors and bus instability. Active terminators regulate the termination voltage using internal circuitry, providing more consistent impedance matching than passive designs — particularly important on longer buses or buses with many devices. The 68-pin HD wide SCSI connector was the standard interface for SCSI-2 Wide and later Ultra SCSI devices from the mid-1990s onward, found on workstations, servers, storage arrays, tape libraries, and external disk enclosures from manufacturers such as Sun, SGI, HP, and IBM. A plug-on external terminator like the DM2750-02-68ADR attaches directly to the last device's open SCSI port, eliminating the need for a separate termination cable. These terminators remain in use wherever legacy wide SCSI infrastructure is still maintained.
This DataMate DM2750-02-68ADR Active SCSI Terminator is in good used condition. The beige plastic housing is intact with no cracks or significant damage, and the 68-pin high-density SCSI-2 connector shows normal contact wear from prior use. The label is clear and fully legible, confirming model, date code, ADR type, patent, and PWN. Please view our photo set and contact us if you have any questions.
