Overview

The Monoprice 100850 is a purpose-built adapter designed to bridge two common but incompatible SCSI-2 connector formats: the high-density HPDB50 and the older Centronics CN50. For anyone maintaining legacy computing equipment, servers, scanners, or industrial devices that rely on SCSI interfaces, mismatched connectors are a frequent headache. This adapter eliminates the need to replace entire cables or hunt for specialty dual-connector cords by providing a simple inline conversion point.

Housed in a durable plastic shell, the adapter is lightweight and compact enough to fit into crowded cable runs behind equipment racks. While it lacks the metal shielding found on some premium SCSI adapters, the construction is adequate for typical office and studio environments. As a passive adapter, it requires no drivers or external power — simply plug it in and your SCSI chain recognizes the connected devices. For users keeping older SCSI peripherals in service alongside newer infrastructure, the Monoprice 100850 is an economical and reliable connector solution.

Pros & Cons

👍 Pros

Compact form factor takes up minimal space in tight cable setups
Durable plastic housing protects the internal pin connections
Provides a simple, no-driver-needed solution for connecting mismatched SCSI connector types
Affordable way to avoid replacing entire SCSI cables when connector types differ

👎 Cons

Only supports HPDB50 to CN50 conversion, not reversible to other SCSI connector types without additional adapters
Plastic body is less rugged than metal-shelled alternatives for industrial environments
Does not include a SCSI terminator, which must be sourced separately if needed
Limited to SCSI-2 legacy applications with a shrinking pool of compatible hardware

Frequently Asked Questions

What connector types does this adapter convert between?

This adapter converts from an HPDB50 (High-Density 50-pin) connector to a Centronics CN50 (50-pin) connector, both commonly used in SCSI-2 device chains.

Does this adapter support SCSI-2 signaling standards?

Yes, this is a SCSI-2 compatible adapter designed to maintain proper signal integrity between HPDB50 and CN50 interfaces.

Is this adapter male-to-female or male-to-male?

This adapter features an HPDB50 connector on one end and a Centronics CN50 connector on the other, allowing you to bridge cables or devices using these two different SCSI connector styles.

Can I use this adapter in a SCSI daisy chain with multiple devices?

Yes, as a passive connector adapter, it can be used within a SCSI daisy chain. Just ensure proper termination at both ends of the chain for reliable operation.
