  • Converts DB9 male to RJ45 female for modular serial links
  • Gold-plated connector and contacts resist corrosion and maintain signal integrity
  • Supports RS232, RS422 and RS485 protocols for versatile industrial use
  • Female-to-female design enables custom pin-out wiring for specific applications
  • Compact black adapter fits tight panels and rack environments

Rocstor DB9 Serial to RJ45 Adapter

The Rocstor Y10A342-B1 converts a DB9 male connector into an RJ45 female connector. It supports modular RS232, RS422 and RS485 serial links. Gold-plated contacts maintain signal integrity across the interface. The black housing suits rack and bench environments.

Suited for custom serial pin-outs.

Technicians who need to map DB9 signals to an RJ45 patch panel will find the adapter useful. Installers extending serial equipment over structured cabling can terminate their own pin assignments. Buyers who want a ready-made Ethernet connection should look at something else. The adapter does not perform protocol conversion.

DB9 female to RJ45 female gender configuration

One end presents a 9-pin DB9 female socket while the other provides an RJ45 female jack. This fixed gender arrangement determines which cables can attach directly. Verify that your DB9 source is male and your RJ45 cable is male before ordering. A mismatched gender will require an additional changer.

Questions about this item

Will the 9-pin DB9 female side mate with my existing DB9 male cable?

Yes, the adapter provides a DB9 female port that accepts a standard DB9 male plug, letting you keep your current serial cable.

How can I verify the adapter is passing RS232, RS422 and RS485 signals correctly after wiring?

Connect a loop-back plug to the RJ45 female port, run a terminal program at the expected baud rate, and confirm transmitted characters echo back without errors.

Does the package include any RJ45 cable or pin-out guide, or must I supply them?

Only the DB9-to-RJ45 modular adapter is included; you will need to provide your own RJ45 cable and create the pin-out for your specific RS232, RS422 or RS485 device.
