Ugreen DB9 RS232 Female to Female Adapter Cable (1.5m) | 20149

The UGREEN 20149 (model DB101) is a 1.5 m RS232 serial cable with a DB9 female connector on each end. It connects two devices that both have a DB9 male serial (COM) port, such as a computer and a piece of serial equipment.

DB9 female on both ends: Each end has a 9-pin female connector, so the cable plugs straight onto DB9 male ports. This is the cable to choose when both of your devices have male serial ports.

Straight-through wiring: The cable is wired straight through, pin 1 to pin 1 and so on. It passes the serial signals unchanged; it is not a null-modem (crossover) cable.

Screw-locking connectors: Both connectors have thumbscrews that fasten the plug to the port, so the connection does not work loose on equipment that is moved or vibrates.

Passive cable: No power and no driver are needed. The cable simply carries the RS232 signals between the two ports.

Who it's for / Works with

Devices with an RS232 DB9 male (COM) port, for example PCs, PLCs, POS terminals, barcode scanners and modems.

Good to know

This is a straight-through cable, not a null-modem cable. It does not convert RS232 to USB; a computer without a serial port needs a separate USB to RS232 adapter.
