Serial Null Modem Cable – 3m DB9 Female to Female

This 3m Serial Null Modem Cable provides a cross-wired RS232 connection between compatible DTE devices. DB9 female connectors at both ends support direct serial links for industrial controllers, legacy PCs and debugging equipment.

  • Cross-wired null modem design with dual DB9 female connectors, swaps TX/RX signals to realize direct DTE-to-DTE RS232 communication without extra adapters.
  • 3-meter extended length with full aluminum foil shielding, blocks EMI interference and supports stable baud rate up to 115200bps for industrial serial transmission.
  • Nickel-plated DB9 pins & reinforced strain relief, anti-rust and anti-breakage, locked firmly via mounting screws for long-term equipment connection.
  • Standard RS232 pinout, widely compatible with PLC, industrial controllers, serial scanners, legacy PCs and debugging devices.

자주 묻는 질문

What’s the difference between null modem cable and straight-through DB9 cable?

Null modem cable crosses transmit & receive pins to connect two DTE devices directly; straight cable only works for DTE-DCE matching.

Is this 3m F/F null modem cable compatible with industrial PLC programming?

Yes, standard RS232 protocol supports most PLC, serial testing instruments and old COM port equipment for data upload/download.

Does the shielding prevent signal drop in factory electrical environments?

Full aluminum foil shielding reduces electromagnetic interference, ensuring stable serial signal transmission near power equipment.
