The Black Box EYN257T-0050-FF is a 50-foot shielded null modem cable designed for direct serial communication between two DTE or DCE devices. Its metal hood provides robust EMI/RFI shielding, crucial for maintaining signal integrity in industrial or data-intensive environments where interference is a concern. This cable is essential for connecting devices like terminals, modems, or certain industrial equipment that rely on RS-232 serial ports for configuration or data transfer, particularly when direct device-to-device communication is required without a modem.
This cable is compatible with any system requiring a standard RS-232 serial connection with a null modem configuration. It features DB9 female connectors on both ends, suitable for direct connection to devices with corresponding DB9 male ports. It is commonly used with serial console servers, industrial control systems, legacy diagnostic equipment, and specific network devices that require out-of-band management or direct serial links.
The cable features DB9 female connectors, requiring male DB9 ports on the connected devices. The metal hood on each connector should be securely fastened to the device's port to ensure proper grounding and EMI/RFI shielding. Ensure the connected devices are configured for null modem communication (crossed transmit and receive lines) for successful data exchange.
