RS232 DB9 Female to 3.5 mm Jack Adapter

This adapter converts a DB9 serial port into a 3.5 mm three-pole jack for legacy equipment. It provides a 1.8 metre cable run between the two connectors. The unit is supplied new and ready for internal cabling tasks.

DB9 Female to 3.5 mm 3-Pole Male Jack

The connector gender and pin count decide whether this adapter matches your device. One end is a DB9 9-pin female socket and the other is a 3.5 mm 3-pin male plug. Buyers who need a male DB9 or a different jack layout cannot use this part.

Questions about this item

What does the 1.8 m cable length mean when I route this inside a PC case?

The 1.8 m length gives enough slack to reach from a rear-panel DB9 cut-out to an internal header or front-panel jack without strain, but it may leave excess cable to tie down in a small chassis.

Which signals does the 3.5 mm jack carry on this RS232 DB9 adapter?

The 3.5 mm 3-pole male jack provides a three-wire connection — typically transmit, receive and ground — so only basic serial data lines are passed; handshake pins on the DB9 side are not connected.
