Black Box EYN12A-0500 RS232 Foil Shielded Plenum Bulk Cable
Overview
The Black Box EYN12A-0500 is a 500-foot bulk cable designed for reliable RS232 serial data transmission in demanding commercial environments. Its 12-conductor configuration and foil shielding minimize electromagnetic interference (EMI), ensuring data integrity for sensitive serial devices. The plenum rating makes it suitable for installation in air handling spaces, meeting stringent building codes for fire safety and smoke propagation.
Compatibility
This cable is designed for use with any RS232 serial device requiring a 12-conductor connection. It is compatible with a wide range of equipment including industrial automation controllers, point-of-sale systems, network devices with serial consoles, and legacy security system components. Ensure your connected devices utilize a 12-conductor pinout for full functionality.
Installation Notes
The foil shield should be properly terminated at one end (typically the equipment end) to prevent ground loops. The plenum jacket requires careful handling during installation to avoid damage, but offers superior fire resistance compared to non-plenum rated cables. Ensure proper strain relief is used at connection points to maintain cable integrity over time.
