Ruth's sister 3.5mm DB9 Serial Cable 232

SKU CH-CK3Q-G8E5J

Connects a 3.5 mm serial port to a DB9 RS232 interface for legacy device communication

  • Connects 3.5 mm devices to DB9 serial ports
  • Male-to-male wiring links two DB9 interfaces directly
  • 9-pin RS-232 layout matches standard serial pinout
  • New condition ensures reliable out-of-box operation

3.5mm to DB9 Serial Link

This new cable connects a 3.5 mm jack to a DB9 male plug using RS-232 signalling. It carries nine pins for standard serial communication. The compact 3.5 mm end fits panels and devices where a full-size port will not fit. Builders use it to add a legacy COM port to modern enclosures.

Makers adding a single serial port

The cable serves hobbyists and technicians who need one RS-232 connection on a tight bracket. It does not suit installations that require a second serial port or a different connector gender. Users needing longer runs or shielded variants should look elsewhere.

Questions about this item

What serial port does the 3.5 mm plug on this cable connect to?

The 3.5 mm male plug connects to a 3.5 mm serial port on a motherboard or add-in card that uses the same 9-pin RS232 pinout.

Can I keep my older DB9 peripheral when switching to a board with only a 3.5 mm header?

Yes, the DB9 male end on this cable mates with your existing DB9 device while the 3.5 mm end plugs into the newer header.
