Pair of RS232 DB9 to RJ45 Adapters

This pair of Vszerda adapters converts a DB9 serial port to an RJ45 jack so that RS-232 signals can travel over standard Cat5e or Cat6 network cable. They are intended for installers and technicians who need to extend serial console or device connections beyond the reach of a direct DB9 cable. The adapters require no external power and operate as a passive link.

Moulded Strain Relief and Finger-Tight Screws

Each adapter features a moulded strain-relief body, nickel-plated contacts and finger-tight screws that secure the DB9 connector without tools. Double shielding on the connector minimises crosstalk and suppresses noise during signal transmission. The RJ45 jack accepts standard Ethernet patch cables, allowing the use of existing structured wiring runs up to 20 metres.

Replaces Long Direct Serial Cables

This solution replaces bulky, length-limited serial cables by leveraging inexpensive twisted-pair infrastructure already present in many buildings. The jump is worthwhile when the serial device sits farther than a practical DB9 cable allows but within 20 metres of a network drop. It is not suited for connections that require active signal regeneration beyond that distance or for single-ended use without the matching adapter.

Questions about this item

Does the DB9-to-RJ45 adapter support full RS-232 signalling over Cat5e or Cat6 cable?

It converts DB9 (RS-232) signals bi-directionally over standard Cat5e or Cat6 copper cable, with nickel-plated oxygen-free copper contacts and double shielding to minimise crosstalk and noise.

What physical space and screw type does each adapter need for a secure DB9 connection?

Each unit has a moulded strain-relief body and finger-tight thumbscrews on the DB9 side, so allow room for the connector depth plus cable bend radius at the panel or device port.

What is the correct installation sequence to avoid a non-working link?

Deploy two adapters as a pair — one at each end — connect both DB9 ports, then run a single Cat5e/Cat6 patch cord between the RJ45 jacks; a single adapter alone will not pass data.
