Gold-Plated USB 2.0 to DB9 Serial Cable

This cable connects a serial DB9 device such as a modem or CNC controller to a USB 2.0 port on a computer. It uses the PL2303 chipset and measures 6.6ft in length. The adapter is USB bus powered and requires no external power supply. It is designed for users needing to link legacy RS232 equipment to modern systems.

Sustained Transfer at 1Mbps

The USB 2.0 interface provides a data transfer rate of 1Mbps for continuous communication with connected serial hardware. Tinned copper conductors and triple shielding protect signal integrity during extended sessions. Driver support covers Windows 11, 10, 8.1, 8, 7, Linux and Mac OS for stable long-term operation.

Replaces Missing Native Serial Ports

This adapter upgrades computers that lack a built-in DB9 port, letting cashier registers, scanners, label printers and PLC controllers stay in service. It is not suitable for cutting plotters or devices requiring a null modem adapter unless one is added separately. The jump is worth it when legacy serial gear must talk to current USB-only machines.

Questions about this item

Does the PL2303 chipset draw enough USB bus power to run hot during all-day use?

The adapter is USB bus powered with no external adapter needed, so power draw stays within normal USB 2.0 limits and it does not generate noticeable heat.

Must my computer already have a free USB 2.0 Type-A port for this cable to work?

Yes, the cable has a USB 2.0 male connector and requires an available USB Type-A port on the host computer.

Will the DB9 female connector mate with the 9-pin serial port on my legacy CNC controller?

The cable provides a standard RS232 female DB9 interface, matching the 9-pin serial ports found on CNC, PLC and POS equipment.
