Why choose it

This cable eliminates the need for a modem or null modem adapter, saving time and reducing connection points. The cross-wired configuration ensures proper signal handshaking between devices, while the shielding and quality materials provide reliable data transmission even in electrically noisy environments.

Ideal use cases

• Direct file transfer between two legacy PCs with DB25 serial ports
• Connecting a PC to a serial printer or plotter that requires null modem wiring
• Configuring network equipment or industrial machinery via console port (with appropriate gender changer if needed)
• Laboratory or test bench setups where serial communication between instruments is required

Good to know

The cable is grey in color and features molded connectors with thumbscrews for a secure, vibration-resistant connection. It is compatible with any device that has a DB25 female serial port and requires a null modem connection. For devices with DB9 ports, an adapter may be necessary.
