CBL ASY,15FT DB9 M/F, NULL MDM MFR P/NO: 10D1-20215 3R0301695
This cable assembly is a specialized 15-foot DB9 Male to Female null modem cable, designed to facilitate direct serial communication between two devices (Data Terminal Equipment or DTE) without the need for an intermediary modem (Data Communication Equipment or DCE). This “crossover” wiring reverses the transmit and receive signal lines, ensuring that data is correctly exchanged between the two connected devices. Null modem cables are typically used for specific applications like direct PC-to-PC data transfer, debugging legacy hardware, controlling industrial equipment, or managing network switches and routers through a serial console. With its generous 15-foot length, this cable provides significant flexibility for device placement. The Male-to-Female configuration allows it to function as a null modem extension, or as a null modem cable for connecting a male DB9 device to a female DB9 port. Constructed with high-quality components, it often includes features like foil shielding to prevent EMI/RFI interference and molded connectors with thumbscrews to ensure a secure, stable connection.
