DB25 male to RJ45 RS232 adapter

This adapter connects a DB25 male serial port to an RJ45 interface for RS232 signalling. It is intended for technicians and hobbyists who need to link legacy modem or console equipment to modern cabling. The compact form factor suits internal routing inside enclosures or patch panels. No external power is required for the passive connection.

Straightforward pin-to-pin installation

The DB25 plug mates directly with the equipment port and the RJ45 jack accepts a standard patch lead. Mis-wired cables are the most common issue because RS232 pin assignments vary between vendors; verify the wiring diagram before crimping or purchasing a lead. The 25 contacts leave no spare pins for custom signals, so the adapter cannot support parallel or proprietary protocols.
