UGREEN DB9 RS232 Male To Female Adapter Cable | DB101
The UGREEN DB101 is a DB9 (9-pin) RS-232 serial cable with a male connector on one end and a female connector on the other. It is wired straight through, pin to pin, so it works as an extension cable between a computer's COM port and a serial device.
Available lengths: 1.5 m (#20145), 2 m (#20146) and 3 m (#20147), black.

Straight-through wiring: Each pin connects to the same pin on the other end (1-1, 2-2 ... 9-9). This is the standard wiring for extending an RS-232 link; it is not a null-modem (crossover) cable.
30AWG pure copper core: The conductors are 30AWG pure copper, which carries the serial signal reliably over the cable length.

Gold-plated contacts and foil shielding: Gold-plated contacts resist oxidation, and aluminium foil shielding reduces interference from nearby cables and equipment.
Screw-lock connectors: Both connectors have thumb screws, so the cable stays firmly fixed to the port and does not work loose.
Who it's for / Works with
PCs and RS-232 (COM) devices such as modems, routers and industrial machines.
