Description

DB25 Female to Female Serial Null Modem Cable RS-232 25-Pin F/F Gender Changer

This is a null modem serial cable with DB25 female connectors on both ends. It cross-wires the transmit and receive lines to enable direct communication between two RS-232 devices that would otherwise require a male-to-female connection.

Specifications & What's Included

  • Connector Type: DB25 Female to Female
  • Interface: RS-232 / EIA-232
  • Pin Count: 25
  • Configuration: Null Modem / Gender Changer
  • Compatible With: RS-232 serial devices with DB25 male ports
  • Cable only; no accessories included

Applications

Null modem cables were standard for connecting legacy computer equipment, terminals, modems, and industrial control systems. This cable type was widely used in data centers and telecommunications environments to link two devices without an intervening modem. It accommodates scenarios where two male DB25 connectors need to communicate directly, adapting the gender mismatch while maintaining proper serial signal routing.

Condition: Used
This DB25 Female to Female RS-232 serial null modem cable has been inspected and is in good used condition. It was pulled from a working environment where it was actively in use. The cable jacket shows some surface discoloration and light age-related yellowing consistent with older surplus stock, and the connector shells show minor wear, but the 25-pin contacts on both ends appear clean and undamaged. Please view our photo set and contact us if you have any questions. Please note: We have multiple units in stock — yours may not be the one shown in the photos, however, it will be similar in condition and function.
