InLine null modem cable DB9 Pin female / female molded red 3m

InLine null modem cable with 9-pin Sub-D female connectors on both ends, molded die-cast plugs and a 3 m red sheath. Designed for direct serial data transmission between two PCs, notebooks or servers via RS232/RS422/RS485 compatible COM ports. Check the PIN assignment before use.

Advantages

The cable uses a null modem wiring configuration to allow two DTE devices to communicate without a modem or additional converters. Molded die-cast connectors increase mechanical durability and the colored sheath improves visibility in crowded cable runs. Standard Sub-D 9-pin female connectors ensure compatibility with common serial devices and equipment.

Suitable for

• Direct serial connection between two computers or notebooks
• Connecting servers or industrial devices with Sub-D 9 COM ports
• Extending or adapting RS232, RS422 and RS485 interfaces
• Temporary or fixed setup where a visible cable color is beneficial

How to use

Connect each end of the cable to the Sub-D 9-pin serial ports of the two devices. Ensure both devices are configured for serial communication (matching baud rate, parity, stop bits). Verify the null modem PIN assignment matches the device expectations. Secure connectors to prevent accidental disconnection during use.

Usage recommendations

For reliable communication, set identical serial port settings on both devices and avoid routing the cable near high-voltage or strong electromagnetic sources. If communication issues persist, check PIN mapping and consider using shielded ports or ground continuity checks.
