CBL ASY,10FT DB9 M/F, NULL MODEM MFR P/NO: CN-11910 3R0301696
This cable assembly is a 10-foot DB9 Male to Female null modem cable designed for specialized serial communication between two devices (Data Terminal Equipment or DTE) without requiring a modem. The “null modem” configuration involves a crossover wiring of the transmit and receive lines, which is necessary for two DTE devices to communicate directly. This cable is commonly used for direct PC-to-PC data transfers, debugging legacy equipment, and configuring network switches or routers through a serial console. With its generous 10-foot length, this cable provides significant flexibility for device placement, accommodating various setup requirements. The Male-to-Female configuration allows it to function as a null modem extension or to connect a male DB9 device to a female DB9 port. These cables are typically constructed with a foil shield to protect against EMI/RFI interference and feature molded connectors with thumbscrews to ensure a secure and stable connection.
