DB9 Male to RJ45 Female Modular Adapter

Configure a custom serial pinout between a DB9 male port and an RJ45 female connector using a compact passive modular adapter.

Custom serial pinout

The modular design lets an installer arrange the internal leads for the required RS-232, RS-422 or RS-485 wiring scheme.

DB9 male to RJ45 female

Joins equipment with a 9-pin male D-sub interface to structured cabling terminated with an RJ45 plug.

Compact passive design

Requires no external power, software or drivers and fits neatly into service kits or equipment cabinets.

Built for repeatable installs

Useful when deploying a known serial pinout across multiple devices or replacing a purpose-wired adapter.

Why this model fits the job

Configure a custom serial pinout between a DB9 male port and an RJ45 female connector using a compact passive modular adapter. The design focuses on the exact connector, signalling and compatibility requirements shown in the current StarTech.com specification, helping buyers select the right part without relying on broad compatibility claims.

Compatibility checklist

Map the required pinout before terminating the internal leads.
Confirm that the equipment uses compatible electrical signalling; the adapter does not convert between RS-232, RS-422 and RS-485.
Use this model only when a DB9 male and RJ45 female connector arrangement is required.

Common applications

Create a purpose-wired serial console or control lead
Adapt installed RJ45 cabling to a DB9-equipped device
Standardise repeatable serial pinouts for service deployments

DeviceDeal purchase confidence
