DTECH 15 ft Straight Through Serial DB9 Cable Female to Female 9 Pin COM Port Cord

Bottom line: The DTECH 15 ft Straight Through Serial DB9 Cable Female to Female 9 Pin: Full straight-through pinout 1-1 through 9-9 plus ground, not a partial 3-wire wiring; main trade-off: female-to-female only; connecting two DB9 male ports needs a gender changer.

Pros & Cons

Pros

  • ✓ Full straight-through pinout 1-1 through 9-9 plus ground, not a partial 3-wire wiring
  • ✓ 15 ft (5 m) run reaches equipment racked across a bench, not just side-by-side units
  • ✓ Thumbscrews on both DE9 ends lock the connection against vibration and accidental pulls
  • ✓ Gold-plated pins resist corrosion on legacy COM ports that sit unused for years

Cons

  • ✗ Female-to-female only; connecting two DB9 male ports needs a gender changer
  • ✗ Straight-through wiring, so null-modem PC-to-PC links require a separate crossover adapter
  • ✗ Thin 30AWG conductors are aimed at signal use, not powering attached devices
  • ✗ Needs a USB-to-serial adapter on any modern PC without a physical COM port
