Black Box EMN25C-0025-MM RS232 Double Shielded Extended Cable
Overview
The Black Box EMN25C-0025-MM is a 25-foot RS-232 serial cable designed for reliable data transmission in environments where signal integrity is critical. Its double shielding minimizes electromagnetic interference (EMI) and radio frequency interference (RFI), making it suitable for industrial automation, point-of-sale systems, and other applications requiring stable serial communication. This cable ensures that data sent between devices, such as a barcode scanner and a terminal, remains clean and uncorrupted over its length.
Compatibility
This cable utilizes standard DB9 (9-pin) connectors, making it compatible with virtually any device featuring an RS-232 serial port. This includes a wide range of industrial equipment, legacy computer systems, network devices requiring console access, and peripherals like printers, modems, and external drives. It is designed to work with any system that adheres to the RS-232 communication standard.
Installation Notes
The EMN25C-0025-MM features molded DB9 connectors with integrated strain relief to prevent damage from bending or pulling. The double shielding provides enhanced protection against noise, which is particularly beneficial when running the cable near power lines or other sources of electromagnetic interference. For optimal performance, ensure connections are secure and avoid routing the cable parallel to high-voltage AC power cables for extended distances.
