Black Box 20ft RS232 Serial Cable DB9 Male/Female Shielded PVC

Overview

The Black Box BC00232 is a 20-foot RS232 serial extension cable designed to provide reliable connectivity between two DB9 devices. It supports all nine signals for complete RS232 communication, ensuring that hardware handshakes and control lines function properly. This cable is ideal for extending connections in setups involving point of sale systems, industrial controllers, or legacy computer equipment where the original cable length is insufficient.

Constructed with 26 AWG stranded conductors inside a beige PVC jacket, the cable balances flexibility with durability. A Mylar shield surrounds the wires to reduce electromagnetic and radio-frequency interference, making it suitable for environments with dense electronic equipment. Molded hoods and thumbscrews on both ends secure the connectors firmly, minimizing the risk of accidental disconnection during use.

Key features

• DB9 male connector on one end and DB9 female connector on the other for straightforward device linking
• 20-foot length provides extended reach without compromising signal integrity
• All nine conductors pinned straight through to maintain full RS232 functionality including hardware handshakes
• 26 AWG stranded wire offers a flexible cable that withstands routine bending and movement
• Molded hoods with thumbscrews ensure secure connections and reduce strain on the cable ends

Connectivity and compatibility

This cable is compatible with any device featuring a DB9 serial port, including AT-style mice, vintage EGA or CGA monitors, console ports, and various industrial or legacy computer systems. Its full pin-through wiring ensures that all standard RS232 signals, including control and handshake lines, are transmitted without interruption. The thumbscrew connectors provide a secure fit, making it suitable for installations where stable, long-term connections are required.

Ideal uses and environments

The BC00232 cable works well in environments where extending serial connections is necessary, such as retail point of sale stations, manufacturing floors, or IT racks with legacy equipment. Its shielding and durable construction make it a strong choice for locations with significant electromagnetic interference or frequent cable movement. Technicians and system integrators will appreciate its reliability when servicing or upgrading older hardware setups.
