DB9 Female to 3.5mm 3P Male Adapter

This new adapter connects a DB9 female serial port to a 3.5mm 3-pole male jack. It provides a direct link for RS232 serial communication between legacy equipment and devices that use a 3.5mm serial interface. The cable is ready for immediate use in compatible setups.

Suits technicians linking older serial hardware

It is not for users who need a USB connection or a different pin configuration. Buyers requiring a longer cable run or a moulded strain-relief design should look at other options. No driver installation is required for the passive adapter.

Questions about this item

What serial port does my device need for the DB9 female connector to fit?

The adapter mates with a standard DB9 male RS-232 port, so your equipment must present that 9-pin interface.

Will the 3.5 mm plug carry the same RS-232 signals as a full DB9 cable?

The 3.5 mm 3-pole jack passes only the lines wired by the adapter, typically transmit, receive and ground, not the full DB9 pinout.
