DTECH 1.5ft COM Port Serial Cable Male to Female RS232 Extension 9 Pin Straight Through Cord (0.5 Meter, Black)

Bottom line: The DTECH 1.5ft COM Port Serial Cable Male to Female RS232 Extension 9: True straight-through DB9 pinout (1-1 through 9-9, G-G) — no null-modem surprises; main trade-off: 1.5 ft (0.5 m) only — too short to relocate gear more than an arm's length.

Pros & Cons

Pros

  • ✓ True straight-through DB9 pinout (1-1 through 9-9, G-G) — no null-modem surprises
  • ✓ Screw locks on both DB9 ends keep the connection seated during data transfer
  • ✓ AL foil shielding on the run, standard for RS-232 signal integrity
  • ✓ 30AWG conductors follow standard wire color code, easy to re-solder or repin

Cons

  • ✗ 1.5 ft (0.5 m) only — too short to relocate gear more than an arm's length
  • ✗ Straight-through wiring will not work for null-modem or crossover setups
  • ✗ Male-to-female extension only; won't join two male or two female ports
  • ✗ No VGA compatibility despite the similar 9-pin look — RS-232 signaling only
