USB RS232 to 3.5 mm Serial Adapter

This USB to RS232 converter terminates in a 3.5 mm stereo mini jack. It provides a serial link for legacy equipment that uses a 3.5 mm audio-style connector for RS232 signalling. The adapter suits technicians and hobbyists who need to configure or debug such devices from a modern USB port.

Check connector wiring before ordering

Verify that your target device expects RS232 voltage levels on a 3.5 mm tip-ring-sleeve plug. Some equipment uses the same jack for different pin-outs or for audio instead of serial data. Confirm the required gender and pin assignment in the device manual to avoid a mismatch.
