C2G 03019

Overview

The C2G 3019 is a 6-foot serial RS232 null modem cable designed to connect devices with DB25 male and DB9 female ports. It enables direct communication between two devices by crossing the transmit and receive signals, making it suitable for linking older computers, industrial equipment, or networking devices that rely on serial communication. Its durable construction and shielding ensure reliable performance in environments prone to electromagnetic interference.

Key features

• 6-foot length provides flexibility in device placement without strain on connectors
• DB25 male to DB9 female connectors support common serial port configurations
• Null modem wiring crosses transmit and receive lines to allow direct device communication
• Overmolded cable design offers strong strain relief for durability during frequent use
• Foil shielding reduces electromagnetic and radio frequency interference for stable data transfer
• Thumbscrew connectors secure the cable firmly to devices, preventing accidental disconnections

Key specs

• Cable length: 6 feet (1.8 meters)
• Connector 1: DB25 male
• Connector 2: DB9 female
• Wiring type: RS232 null modem (crossed transmit and receive)
• Shielding: Foil shield for EMI and RFI protection
• Design: Overmolded with strain relief

Connectivity and compatibility

This cable is compatible with devices featuring DB25 male and DB9 female serial ports, commonly found in legacy computers, industrial controllers, and networking equipment. It supports RS232 communication standards and is ideal for setups requiring null modem connections without additional adapters or converters.

Ideal uses and environments

The C2G 3019 fits well in technical environments where reliable serial communication is essential, such as industrial automation, network troubleshooting, and legacy system maintenance. Its shielding and robust design make it suitable for use in areas with high electronic noise, including manufacturing floors and server rooms. Technicians and engineers will find it a practical tool for connecting and testing serial devices.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
