2m RS232 Serial Cable – DB9 (DE-9) Male to Male Straight-Through COM Port Lead

The 2m 9-pin DB9 (DE-9) Male to Male Straight-Through RS232 Serial Cable is a serial communication cable designed to directly link two RS232-compatible devices with male DB9 (DE-9) connectors. It's a straight-through pinout cable, meaning each pin is mapped directly (1:1) from one end to the other — essential for standard data communication between devices like modems, routers, and industrial equipment.

The 2m 9-pin DB9 (DE-9) Male to Male Straight-Through RS232 Serial Cable is also known as a DB9 M-M RS232 Cable, DE9 Straight Serial Cable, 2m Male DB9 Serial Lead, COM Port Cable, and RS232 Serial Extension Lead.
