DB25 Male-to-Male Gender Changer

This shielded adapter connects two DB25 female ports, converting the gender of a serial or parallel interface. It suits technicians maintaining legacy industrial, laboratory or networking equipment that still relies on 25-pin D-sub connectors. The compact metal housing protects signal integrity in electrically noisy environments.

Shielded D-Sub Interface Limits

The DB25 standard carries up to 25 conductors but offers no defined maximum cable length or data rate; those depend on the connected devices and cable quality. Shielding reduces EMI pickup, yet the interface itself cannot guarantee performance beyond the specifications of the host equipment. No active circuitry is present to boost or regenerate signals.

Straight-Through Pin Mapping Decides Fit

This changer uses a straight-through pin assignment, meaning pin 1 connects to pin 1 across the adapter. It will not work where a null-modem or crossover wiring is required, so buyers needing reversed transmit and receive lines must select a different adapter. Verify the pin-out before ordering.
