Product information

Description

The StarTech.com 10 ft Cross Wired DB9 to DB25 Serial Null Modem Cable Female to Male Grey is a practical solution for connecting older serial peripherals and legacy hardware. Measuring 3 meters in length, this cable facilitates stable serial communication and data transfer between computers and devices with differing port configurations. Built with attention to quality and safety, it includes shielding against electromagnetic interference and complies with CE and RoHS standards.

Advantages

This null modem cable ensures dependable data transmission between legacy systems by utilizing cross-wired pinouts specifically designed for direct device-to-device communication. The integrated molded connectors provide essential strain relief, preventing cable damage at the connection points during regular use and adjustment. High-grade shielding protects transmitted data from external electromagnetic interference, maintaining signal integrity even in environments with multiple electronic devices.

Suitable for

  • Connecting a 9-pin serial device to a 25-pin serial port
  • Transferring files directly from PC to PC via serial connection
  • Linking legacy hardware, industrial equipment, and older peripherals

This cable is not designed for straight-through serial connections. If your specific hardware setup requires a pin-to-pin straight-through configuration rather than a null modem crossover, this cable will not establish communication.

Key specifications

  • Cable length: 3 meters (10 ft)
  • Connector 1: DB-25 male
  • Connector 2: DB-9 female
  • Wiring type: Cross-wired / Null modem
  • Jacket material: PVC
  • Color: Grey
  • Compliance: CE, RoHS

To use this cable, first verify that your devices require a null modem and cross-wired connection configuration. Power off the equipment before plugging the DB-9 female connector into the corresponding 9-pin port and the DB-25 male connector into the 25-pin serial port. Secure any thumbscrews on the connectors to ensure a stable physical connection, then power the devices back on and initiate your data transfer or terminal communication software.

What to consider before purchase

  • Verify whether your peripheral or computer requires a null modem or straight-through cable
  • Check the physical port types and pin counts available on your legacy devices
  • Ensure the 3-meter length is sufficient for the distance between your connected equipment

Always consult your device manufacturer documentation to confirm pinout requirements before connecting serial hardware, and store the cable in a dry location away from sharp bends to prolong its functional lifespan.
