## Features

- INSTANT DB9 SERIAL PORT FROM USB: Add an rs232 to usb adapter connection to any modern laptop or desktop instantly. Supports PLCs, barcode scanners, GPS units, modems, and other legacy DB9 connectors with no external power required. Bus-powered from any USB port.
- GENUINE FTDI CHIPSET FOR STABLE PERFORMANCE: Built with an authentic FTDI chip, not a Prolific or clone chip, for reliable RS-232 data transmission over 1,000kbps. Eliminates driver failures and blue screen issues reported with clone-based serial adapters on Windows 11, 10, and earlier.
- DUAL-COLOR LED INDICATORS FOR REAL-TIME DIAGNOSTICS: Individual LED indicators monitor each RS-232 signal pin, TXD, RXD, DTR, DSR, RTS, CTS, DCD, and RI, in green or red. Confirm live data flow and troubleshoot serial connections without any additional software or test equipment.
- BROAD OS SUPPORT AND PLUG AND PLAY SETUP: Works with Windows 11, 10, 8, 7, Vista, XP, Linux, and macOS out of the box. The FTDI USB to serial drivers are widely supported across major operating systems and retains COM port assignments across reboots, a critical advantage over Prolific-based alternatives.
- COMPACT 16-INCH CABLE FOR RACK AND SERVER INSTALLS: The convenient 16in. length keeps cable runs tidy in server racks, industrial panels, and bench setups. The compact USB connector and short cable design reduce port congestion where space is limited around recessed or closely spaced USB 2.0 ports.

## Questions & Answers

**Q: Can you use this adapter with a null modem, or straight through extension cable?**
A: This product is compatible with both straight through and NULL modem cables.

**Q: does this come with a cd?**
A: Hello,

Yes it does, we also offer the drivers and guide on our website.

**Q: Does this support the rs232 control lines?**
A: +Our software does not use the RTS/CTS/etc functions so I don't know. Since it does have status indicators (something we look for so you can be sure it is being talked to) which include DTR, DCD, RI, CTS, RTS & DSR I would presume it does.

**Q: will this work for gerber plotters?  i have a gerber gs15 it came with a 25 pin db to 9 pin serial rs232 cable, as my laptop only has usb ports.**
A: This has a DB9 male connector on it.
