4.5 Feet DB9 (9 Pin) Female to DB25 (25 Pin) Male Empty Modem Serial Parallel Printer Cable YOUCHENG for DTE PC Mac Linux Data Transmission Communication
Bottom line: The 4.5 Feet DB9: Null modem wiring crosses TX/RX (DB9 pin 2 to DB25 pin 3, pin 3 to pin 2); main trade-off: listing calls the DB25 end both male and female; confirm the gender your port needs.

- ✓ 4.5 ft (140 cm) run reaches a printer or second PC on the same desk
- ✓ Full pin-by-pin map published, so you can check the wiring before you connect
